I don't care whether you delete this topic or not. It is, somewhat, development related. I'm just doing a new topic for this thing because, if I were to post this on a ROM thread, it would have become covered with 100 other posts within the hour, decreasing the chances of the developer reading it! My hope, with this thread, is that someone interested or someone who knows about this, sees it and does something about it! Please read first, and if you, the one who has the power to delete threads for whatever reason, consider it utterly useless and retarded, delete it.
I'm a new DHD user (switched over from the Desire). This issue was in Sense ROMs for the Desire, as well. The Desire S had this problem with stock GB, too.
In CM-based ROMs such as MIUI (which is what I'm currently using), you get an "Advanced" section under Wireless Networks. From there, you can choose the wi-fi channels (11, 13, 14). On a freshly flashed MIUI, no channel is selected. I have two wi-fi networks in my appartment (one is mine, one is from a neighbour). That second wi-fi network, from my neighbour... my phone does not see it (unless I choose 13 or 14 wi-fi channels).
Funny thing. That neighbour's wi-fi... it's set on channel #3. It's a MSI RG54SE II router, if that matters.
Now, on Sense ROMs, such as Android Revolution HD and RunnyDrOiD (the ones I have tried so far), you don't get the option to choose the channels. So... that RG54SE II is unseen by my phone.
Back when I was having the Desire... Only LeeDrOiD ROM had that "Advanced" section under Wireless Networks. Not sure if that's the case with his ROM for the DHD, as well...
So, this thing is not only for the DHD. It's also for the Desire, and the Desire S. My gilfriend has a DS, and until I convinced her to let me unleash her phone's lockers and flash something on it, she could only see 3 Wi-Fi`s (stock 2.3.3, that is), while I could connect to all 20 that were available in the zone.

Hope you get my point. Hope you know what I'm talking about. Hope I'm not the only one that noticed this!!!
If anyone has any idea on how to solve this... please tell me. I have tried LeeDrOiD's "Adhoc networking" (that was the only network-related addon I could find, so...) patch, but that didn't do the work. I don't know what will, since there isn't any addon for this... or I'm blind? Open my eyes, then - KINDLY, not with a banhammer.

This is not the answer you're looking for, but it's worth a mention. You should just ask your neighbor to use a recommended channel. I notice that you're outside of the U.S., where you are supposed to use channels 1, 5, 9 or 13 to prevent wi-fi networks from interfering with each other (within the U.S. you are supposed to use channels 1, 6 or 11). You can make up a story and tell your neighbor that his oddball channel 3 configuration (that he probably decided to use for no good reason) is causing interference with your own network, and you have the technical proof to back it up. From Wikipedia:
"There are 14 channels designated in the 2.4 GHz range spaced 5 MHz apart (with the exception of a 12 MHz spacing before Channel 14). As the protocol requires 25 MHz of channel separation, adjacent channels overlap and will interfere with each other. Consequently, using only channels 1, 6, 11 is recommended in the US to avoid interference. In the rest of the world, the four channels 1, 5, 9, 13 are recommended."
Maybe you can just get your neighbor to follow the rules and switch his network to channel 1, 5 or 9. Then every ROM that you use will have no problem connecting to his network and the problem is solved. I'm assuming you have his permission to use his network resources.
Both my Huawei and his MSI router are configured to channel 3. I put it to that, because there are other 10 networks within this area, and I thought... meh... perhaps they're not using the same channel, lol. Anyway, with the phone, on 14 channels, I only see 5 networks, including mine. With the laptop, I see about 11, so I believe this applies to whatever networks there may be outside, too...
The neighbour I'm talking about... I don't have his permission. I think it's one of those 50 year old couples who don't give a **** about what hardware the ISP installs in their home. Most older-than-45 people here, in my country, know nothing about Wi-Fi, and, since they don't even use it... I wouldn't be surprised if the people who own that MSI router don't even know it's there.
Anyway... the gateway, interface, whatever (192.168.1.1) is accessible, and the user/pass are not changed ("admin', that is). It ain't got a password, neither, obviously. So I could get in and change everything I wished regarding WLAN. Too bad it ain't got /n, but still... I'll try to change the channel even further, and try again with a Sense ROM.
Still, that doesn't fix the issue. Downtown, the most crowded place in the entire city... there are about 25 Wi-Fi networks around (at least that's what I can detect with my phone). My phone (CM-based ROM) can see them all. My girlfriend, with her stock ROM`ed Desire S, could only see 5 or 6. That is no longer the case now, since she's got MIUI, too. And I believe this is the issue with all Sense ROMs : you see 30% of the WLANs you'd see with a CM-based ROM...
I can't ask public stores : hey, your wi-fi... it's set to a channel that my phone just can't see, change it!

@Formhault - You risk Jail if you violate the neighbors privacy. It's like you found on the street a wallet full of money and you don't gave back to the injured person.
I posted a thread just like this before and it passed rather unseen. And un touched. Also I asked for a similar situation and had negative answer. But my issue is that I have a VIZIO router.
This is a rather new router and it gives me another option VIZIO HD. Which is more advance and speedier. I have a 12mb connection but I dont have full speed as I cant connect with this.
And a samsung galaxy can also a motorola atrix so I would like to know if someone knows if this can be modified.

Firstly, using a persons WiFi without permission is theft, regardless of whether it is locked or not. Does an open window in someone's house mean you can legally steal there belongings?
Secondly, this is not Development related in the slightest.
Thirdly, you want the XDA community to help you find a solution to break the law? You should search for an answer elsewhere. i.e. not XDA.

After flashing CM6.1 I got the notorious wifi connectivity issue that numerous people have been reporting around the web. The issue is the following:
1: Wifi discovers neighbor's AP but no longer home AP.
2: Wifi problem randomly fixes itself, but sometime comes back and home AP can't be found again.
Many random solutions on the web include removing all stored AP's on the phone, resetting the router, rebooting and power cycling the phone numerous times, etc. Most people report that wifi miraculously start working again after the above but there is no consistency to exactly why and what works.
I tried all of the above with no luck, and even flashed three different roms with different kernels, did wipes, formatted everything inculding boot partition etc.
Here is the ACTUAL problem:
Different regions use different wifi channels. North America uses the first 11, most of the world uses 13, and Japan uses all 14. After flashing CM6.1 it changed the regulatory domain on the phone to only scan the first 11 channels meaning my European router broadcasting on 13 wouldn't show up. This setting seems to be persistent and doesn't change just because a new rom is flashed.
The reason people report the problem to be randomly fixed after a few days (and sometimes coming back days later) is because most routers automatically select which channel to broadcast on and therefore might end up within the first 11 at occasion. If it changes to something higher after that however, the problem is back.
Solution:
Open Settings, Wireless & network settings, Wi-Fi settings. Press "Menu" and select Advanced. Press regulatory domain and change to 14 channels.
To learn more about this and understand which channels are used in which countries, look here: http://en.wikipedia.org/wiki/List_of_WLAN_channels#2.4.C2.A0GHz_.28802.11b.2Fg.2Fn.29
Thanks man, even I still met an issue which was wifi disconnect frequently (usually after 12 seconds or less, it's re-scanning AP and trying to re-connect again) when I was trying to share my broadband internet from laptop to my legend.
BUT, after I update my wlan driver (now using 8.0.0.238 for my Atheros AR5XXX), the issue seems gone.
I found that by updating wlan driver to the very latest driver (for mine is 9.2.0.xxx) is not a guarantee to resolve this problem.
Now, by combining your suggestion and an "appropriate" driver version for my wlan, it work flawlessly until now
PS: driver version which will work varies from devices to devices. Do trial and error if you must
edit: well, not 100% gone, but much better . the connection is far more stable
Could be a problem for some but not all the issues with WiFi. I knew about this and even posted one or two times this check for the number of channels in different other topics as a possible solution. Still there are times when the connection to the "home" AP is done very late after entering in range or switching on the WiFi and the signal is changing from none to full and back frequently, for the same relative position to the router (I'm standing in the same place). Also even if the signal is full or good, the Legend seems not to have Internet connection that is, the weather updates or XDA applications or browser could not connect. This is still happening even if the selection for the number of channels is correct. And also this is not happening with a stock ROM, I made some comparisons between my Legend and one of my friends that has stock ROM. He is having full signal and excellent browsing experience while I have random disconnects or drops in signal level. My thought is that the difference between drivers made by HTC and the ones in CM ROM is the cause. As it is with some other HTC proprietary developments (like Flash implementation or FM radio), could be that HTC spent some more development time in eliminating bugs and making a better driver.
Of course, this will not stop me use CM ROMS, it is a little bit frustrating, but the other things in CM ROM's makes the difference for me.

I think you're right. Yesterday, I tried my friend's phone (which has a stock ROM), using the same AP and there was no dropped signal or disconnected in wifi. I also tried using other android phone brand (5 series from samsung) which also has a stock ROM and there was no problem at all. Drivers is the culprit
Work
Thanks u very much.worked on my milestone
Thanks. Actually worked.

Hello Rapier,
I have installed the CyanogenMod 6.1.1 (stable) on my HTC Desire (GSM / France) with latest radio image (32.49.00.32U_5.11.05.27) and taken some time to configure it. Now, everything seems to run well ... excepted the WiFi (and perhaps also the GSM). My problem is exactlw what you have described:
- on stock ROMs, the WiFi signal is stable and quite strong
- on Cyanogen ROM 6.1.1, the WiFi signal fluctuates, the connection is unstable and gets lost.
I like CyanogenMod ROMs very much. The WiFi issue is the only thing that I was not able to correct. You were speaking about WiFi drivers: would it be possible to extract the WiFi drivers from the latest HTC Desire stock ROM and copy them into the CyanogenMod installation?
My impression is that the CyanogenROM is scanning for networks in the background, even if a stable and strong WiFi network has been found and is currently connected. Perhaps there is a possibility to disable this scanning?
To finish, I have also the impression (I know, this is not very scientific ... but perhaps it could help to determinate where the issue comes from) that the GSM network is also fluctuating. I use WiFi Analyzer (available on the Android market) and when I plot a graph, without moving the phone or even without moving myself, the plot oscillates between -80dBm and -30dBm (I swear that there is nobody playing with the on/off button of my ZyXEL router ).
@sz1a: Thank you very much for your post: this helped me to discover these "hidden" settings, but my configuration is manual on the ZyXEL and everything was fine. Perhaps you should switch the thread to "unsolved".
I'n not a developer, only an ethusiast with a Legend. Also I'm not a Linux expert so I can only guess and experiment...threfore I cannot tell if porting HTC proprietary drivers is possible. I'd say not...if it was, we would have it by now. The main reason I think, is that those drivers are not open source, so nobody can port them since the sources are not available. I'm sure that if it was possible, they'll have been included in CM

pleaaaase help, im running CM 6.1 RC 1
wifi was working fine untill yesterday, i tried to connect to my friends router but couldnt.. i tried putting it in manually too.. then i couldnt connect to any router infact my phone wont even pick up any even my home one.. i tried switching to 14 channs like this said but no luck
any help please
Hey guys, I am currently running ICS mod 2.5 (http://forum.xda-developers.com/showthread.php?t=1364075&highlight=gps) . I just recently noticed the regulatory domain setting on the wifi advanced settings and I have done some searching but I havent been able to find the optimum settings. Now i know some of you would say "well that depends on the networks you will be around and the country you are in" Until this setting showed up on the most recent rom (ICS mod 2.0 er something) I had never seen this setting or any problems.
The first time I found this setting i selected 11 because that sounded right and I could never get a connection- I had to flash my backup. Then a few days ago I decided to come back to ICS mod and flashed 2.5 and had GPS issues so I flashed the fix (http://forum.xda-developers.com/showthread.php?t=1132412&highlight=gps+fixes) and my WIFI dropped out permanently. I would get the neighbors wifi (on a WRT-54G I only know because I set it up ... DD-WRT! ) that is over 500 ft away but not my own TP LINK DD-WRT N-router in my computer room that was 20 ft away? So I flashed all the new radios with fingers crossed ( http://forum.xda-developers.com/showthread.php?t=715485 Thanks Caulk!) That fixed nothing. I flashed this wifi - N fix ( http://forum.xda-developers.com/showthread.php?t=1158629 ) that fixed nothing. I wiped 3x with kings format and flashed the rom from scratch and I still could not pickup my own router. So as I was picking through posts on XDA someone said something about the regulatory domain.... So I decided to look it up and see if anyone else had the same issue. I didnt find any post immediately so I decided to look up the optimum settings- didnt find it immedately so I started plundering. I set my router and my phone to the highest possible settings and BAM! just like that my network was on and I received an IP faster that ever before.
So I ask does anyone have any insight or best practices ? Why did this just become an issue as I have been flashing custom roms since July 4 2009 (I didn't see any fireworks that night) Anyone else have similar issues? I figured since I didnt find anything about this I could start a thread
Also does restricting the channels in an N network hinder the networks speed? As wireless standards allow multiple channels for use by different links to accommodate greater speeds, am I throttling my N network?
Choosing the best Wifi Channel
I've searched through the forums, but don't think this subject has been previously raised.
So, just to simplify this problem, let me demonstrate with a specific example.
Let's say in my vicinity there are four Wifi APs.
Two running Channel 1, and the other two Channel 6.
Now, common sense will tell you to choose Channels 2, 3, 4, or 5, to prevent conflict with other APs.
But, this is where the problem starts.
Though Channels 2/3/4/5 are running on different channels, their actual frequency ranges overlap with each other, including with 1 and 6 (note that Channels 1 and 6 themselves don't overlap each other). Thus, this means that if I choose Channels 2/3/4/5 I'll have all four of my neighbouring APs overlapping with mine.
Wouldn't this be worse than choosing either 1 or 6, since if I choose either of these, I'll only have two APs conflicting with mine.
You are very much correct. Using the 2.4GHz ISM band, only use channels 1, 6 and 11.
Read more at http://www.cisco.com/en/US/docs/wireless/technology/channel/deployment/guide/Channel.html
Basically the channels bleed over 4 channels worth (I think) of frequency. 1, 6, and 11 are far enough apart to avoid this bleedover. So if someone has a channel 2 wireless signal it will affect channel 1. If someone has a channel 5 signal, it will affect channel 1 (I'm pretty sure, it's been a few years since my Wi-Fi college class).
Slow wifi on cm10 on GT 7 p1000
I have searched to death, but cant find a solution or actual discussion on this.
MY p1 is on;-
Baseband ver. P1000XXJPZ

[email protected],,,,mod#1

Build nr. cm_p1-userdebug 4.1.1 eng..20120926.040310 test-keys
performance settings are default- Too scared to touch!
The problem is that wifi is slow, i.e. speedtest.net app shows normal speed, yet ACTUAL performance is very slow. For instance, connecting to the same network and going to the same site, such as Cm 10 nightly downloads, takes about twice as long on my tab as on HTC Desire S or laptop. This goes for most sites and apps including BBC News, Pulse, Bloomberg etc . Even though I'm a newbie, dummy on tech, especially according to my children, I have run cm9 and have flashed every cm10 nightly since they started. Yes, I use it as a daily driver and whilst I got close to going back to cm9, I'm NOT.
So far the wait has been great. I love cm10 and everything I need now works, apart from WiFi tethering. (Does USB tethering work?) It's just this slow wifi that bothers me, if there's any help out there.
3G/HSDPA works fine, fast and smooth. Thanks to everyone for all the great work(cdesai, jenkins, many others)! Even us older, non-tech guys like bloat-free smooth OS'.
Hello. First, great forum- I can feel the love, as well as the collective genius at work here. It's refreshing to find a forum where people actually know their sh*t on a real, technologically advanced level. It's relieving as well, considering the headache that my new G2 is causing... as follows:
This is a Sprint device and I am still within the time frame to return if a resolution is not found.
Issue:
1.) While wi-fi remains connected (doesn't drop), it is terribly slow, averaging .8 - 3 mbps. Whereas, other Samsung android devices are averaging 15-20 mbps. Internet is cable, and I have reset the modem without experiencing any performance increase. (technicolor TC8305C, bgn)
2.) 4g is no better, averaging a mind boggling .5 mbps. (Don't even get me started on 3g- .1-.3 mbps)
3.) If 4g is even able to connect, which is rare... it disappears and and is nowhere to be found, or be (re) enabled.
Attempted (unsuccessful resolutions):
1.) Performed Sprint recommended troubleshooting techniques:
a.) updated profile
b.) soft reset(s)
c.) hard resets- multiple
2.) contacted customer care: received "refreshers," and was walked through numerous settings and performed various resets.
Recommended CC resolution: return device for exchange.
3.) Sprint store attempted to identify problem, and in the process found that their demo, along with employee handsets (G2) as well as new unboxed versions had the same problem. They offered to switch to an S4 or Nexus5 for free, or wait a couple days to see if the LG rep could offer a fix.
(further) Resolution: pending
Here's the deal- I think we can all agree that this phone is kick ass. Therefore, I would rather not switch, as I enjoy the experience it provides, as well as the satisfaction of getting to really bond with a device when troubleshooting them. Though, this phone seems to be pretty 'buggy,' and while I don't mind tinkering with computing devices (been seeing the blue screen since win '95), I'm not sure I want to be dealing with the potential hassle with a device we all rely on day in and day out to be our life blood... plus, just because I don't see/haven't experienced the other issues others have, doesn't mean they won't potentially manifest down the road. :/ Maybe the Nexus 5 is the better choice... but it seems like cost cutting has taken place in a couple areas- battery (2300), and the camera. Almost like the G2 is the flagship and the other is mildly scaled down in certain aspects even though the end result is compelling for both.
Please know that I am scouring middle earth low and wide for resolutions, and have not composed this post without first looking and becoming familiar with other peoples similiar experiences. I will continue to fact find, and I apologize for not reading all related threads before posting, but time is of the nigh, as I am still within a time frame to return in case the problem is inherent to this specific device (a lemon). Plus, I don't quite understand everything you're talking about, as I've never had/chosen to dig that deep into the obscure settings and techniques I've seen listed (and also because I JUST got it) Hence, the user name- g2 n00b.
So thank you in advance for your time in helping with this. It is both greatly appreciated, and not without gratitude on my part. Also, I hope I displayed proper educate by formating this post in a manner which is easy to sort through. K. let the trouble shooting begin.
also, to the mods- sorry if this is thread/issue has already been covered elsewhere. I also posted this issue on another board and nobody had heard of this problem, so I am fairly confident that i may be justified in having poted this. However, feel free to delete/lock/merge/ if I just didn't see it.. but please provide the link so I can further fact find, because I'm stumped. Thanks.
I just did a speedtest on mine (Also on Sprint) using Wifi.
Same speeds I get on my PC.
It's an oddball suggestion but did you disable the Sprint connection optimizer?
Optimizer enabled. Though, I have tried disabling it and running diagnostics to no effect- doesn't matter what I do, it still won't exceed 3mbps, unless I am lucky enough to receive 4g in certain areas.. then it's a 'blazing' 3.5mbps, but usually .8. I have msl code and have adjusted band priorities and still no difference there, including ##72786 to reset default connections to make sure nothing was adversely affected after investigating the issue.
I'm really bummed. I love this phone. I feel like everything I felt I was missing in the S3/S4 are present here. Love the interface, form factor and all of the settings. Maybe I should take Sprint up on there offer to get an S4 a Nexus 5, but I REALLY don't want to go back to caveman battery hog status on the S4 and have to purchase a backup. I imagine the N5 is more efficient in this area, but it still has a 2300 battery vs 3000 in the G2. Needless to say, I'm frustrated and confused.. but often times, such is life.
Any thoughts on the N5, or suggestions to further trouble shoot are greatly appreciated and welcome?
I have disable the connection optimizer and have done this http://forum.xda-developers.com/showpost.php?p=47423537&postcount=1
The only other idea I have is hit up a coffee shop and due a speed test on their wifi.
The sprint stores by me have crappy wifi speed hence the coffee shop.
I seem to have mostly resolved the issue. I switched channels and encryption protocol. Apparently, my g2 didn't appreciate AES very much. Has anyone else seen performance differences with their device when comparing AES to TKIP? If so, are they drastic? I would think AES would be fine with the g2, considering how advanced it is. I consider it to be somewhat unfortunate if I am forced to select TKIP just so I can get a decent connection. That is, unless of course there are settings I can alter in the ##data# screen that can make better use of this encryption. Is there anything I can do now that I have narrowed down the culprit?

What wireless router are you using? I use a D-Link at home and my G2 kept connecting and disconnecting repeatedly. I was able to fix the problem by updating the router's firmware to the latest version. We've never had any problems with other wifi devices on our router, so it seems the G2 has some unique peculiarities WRT wifi.
I'm running AES with no issues, but noticed following.
LG (Sprint) connects first with a slow 72mbps and switches after a while to a faster speed of 433mbps
I have an Asus Router RT-AC66R, if I play around on the router with Frequencies or the wireless mode, LG would go down to a slow speed.
Don't have Optimizer enabled.
I suspect your problem is a router problem and not the phone.
Anyone having issues connecting to wi-fi networks on channels 12/13? On my device I'm unable to see SSIDs in these channels most of the time. Sometimes I can see networks in channel 13.
Am engaging with Google tech support, so will keep you posted.
What country are you in?
UK
I seem to be the only person on my street that knows channel 13 exists. No issues for me connecting. Although I run my phone to my 5Ghz connection normally, I can connect to my 2.4Ghz if needs be.

Good good.
I'm wondering whether it's down to me not activating the SIM in the phone as yet? Like a double check that the phone should be allowed to use 12&13 (rather than just selecting English UK as the language).

There's really no difference in using that over channel 11 in your case with the co-channel interference.
YES!
It's not just me then. Home router (2.4Ghz) is on ch.13 and when i return home the device will not auto-connect until i toggle wifi off and back on again. Wifi works fine until i leave again. connects fine to my wifi network at work but that is different channel and on 5Ghz too.
RMA'd my device and the new one was bad. Wouldn't see my network at all, but wouldn't register my Sim card either so I have just returned this replacement device. Replacement number 2 is on the way.
I switched to ch.12 and the same thing happens at home. Didn't try any other channels as they are too noisy. So I wonder if this is a software issue? I'm in the UK and the router is made by technicolor for Plusnet.

If channel 11 is noisy, then so is 12 and 13.

I seem to be the only person on my street that knows channel 13 exists. No issues for me connecting. Although I run my phone to my 5Ghz connection normally, I can connect to my 2.4Ghz if needs be.

You might want to change to channel 11. With the current setup you are not only killing your own data rates, but also the rates of everyone on channel 11. These channels are not supposed to overlap, because that creates interference. Switch to channel 11.
This is my WiFi situation. I'm normally on CH.13, but switched to 12 as a test.
My 2nd unit arrived last week, and unfortunately it's the same issue as before - no channels 12 or 13, not even visible. I'll be back in touch with Google today.
Hopefully this is a software issue rather than Google/Huawei spec'ing a duff wifi chipset.
Google spoken to and basically it's a case of tough-titty - some devices aren't going to work with channels 12 & 13.
For anyone else reading this, I had this problem and 'solved' it.
If you find that you can't see channels 12 and 13 then it's almost definitely caused by the Wifi country code restrictions.
I got my Nexus 6P here in Korea and initially tried it out with no sim card. Even though the location is set in settings, without a sim card it doesn't get the wifi country code set, and I couldn't see those channels. As soon as I inserted a Korean sim card, I was able to see them.
If you are in the UK or elsewhere, using a local sim card and you can't see those channels then chances are either your country doesn't allow it or the code is already set. Either way, your options are just accept it or try one of the 'not officially supported' ways to getting around it. That's likely why Google said you were out of luck. It's possible but involves rooting etc. I think. Just search for 'change wifi country code android'. Good luck.

I am afraid that the issue is not as simple. I also have problems with channels 12 and 13, however my phone can connect to those channels, but only for a while. I quote the report I filed in the AOSP bug tracker (not yet assigned, though):
Before I continue, I am based in Switzerland, use a Swiss mobile provider (Swisscom), and I bought my phone through Google in Switzerland. This is relevant because in Europe 802.11b/g/n channels 12 & 13 are allowed, while in the North America they are allowed only under "low power conditions" with the effect that, AFAIK, many devices simply do not support them. My Nexus 6P however should (and shall) support those two channels.
Now, the problem.
I have two access points at home, both in the 2.4 GHz band: one on channels 4+6 and the other (normally) on channels 12+13. What I noticed is that my Nexus 6P would initially connect to the strongest signal independently from the channel, as expected, but then after a while (a couple of hours, maybe) would just stop seeing the signal on channels 12 & 13. Not just my own WLAN, but also neighborhood WLANs on the same channels. This means that the phone can be sitting a couple of meters from the AP in my office (channels 12+13) and be connected to the AP at the opposite corner of the building (the one on channels 4+6). I checked with "WiFi Analyzer" and the phone really does not see any signal above channel 11.
Disabling and re-enabling WiFi will make the phone see channels 12 & 13 once again. However after a while the problem appears again.
At home this is just an inconvenience: I moved the frequency of the second AP to a different channel and that "solved" the problem. On the other hand this might be a much more serious problem when I am in an environment where I can't change the WiFi settings. Maybe I want to connect to a public hotspot broadcasting on the "wrong" channels or I am at the office in an area covered by APs on channels 12 & 13. Tough luck.
Incidentally, I saw at least one report of someone who had exactly the same issue: he had to disable WiFi and enable it again to get the phone to connect to his WLAN (on channel 12 or 13, I can't remember). I also have to say that in our household we have a few other Android devices (2 x Nexus 7, 1 x Nexus 9, 2 x Nexus 4, 1 x Moto X Play) running either 6.0.1 or 5.1.1 and a few other devices (iPhone 5S, iPhone 6, laptop, 2 x Kindle) and none exhibits this behavior. It seems to be specific to the 6P.
I suspect that after a while the WiFi driver simply reverts to its default regulatory domain ("US", I assume) and stops listening to channels 12 and 13. Why it might do so is anyone's guess. Maybe doze interferes with the driver.
Same problem here. The only way to reconnect to WiFi channel 12 or 13 is to manually switch WiFi off and on again on the 6p.
I'm in Hungary.
Guys, there is a thread in the Nexus Help Forum and I reported the issue in the AOSP Bug Tracker. Add your contributions to those threads and star them. Let's try to bring this to Google's attention, otherwise we will never get any action on this topic.
Edit: For some reason I can't add links to the post. Please search issue 197106 ("WiFi 2.4 GHz channels 12 & 13 not working properly on Nexus 6P running 6.0.1") in the AOSP Bug Tracker and the post "My Nexus 6P can't connect to Channel 12 or 13 WIFI's" in the Google Product Forums.

I have been trying for a week to extract some information from Google and Huawei, but I must say that their support just doesn't know anything about this issue. It's even difficult to get someone to understand what the problem is: one Google support guy thought I was talkng about LTE channel 12, for example. Huawei support started talking about options in the WiFi settings that are not there, then they wanted to guide me through adding a new WLAN, and finally started clutching at straws, giving more and more fantastic explanations of why it might be so.
Bottom line is: nobody I talked to ever heard about this issue.
I would really like to understand if it could be a hardware issue (which I honestly doubt) because my RMA window is closing soon and I don't honestly know what to do: apart from this WiFi issue my 6P is absolutely flawless and I do not want to risk getting a new telephone only to find out that WiFi still does not work as expected and it's also got other issues. (And, yes, something like this already happened to me.)

Hello, I also have the same problem. As I can report it to Google? I have not found a way.

Did you call the Google Store Support? I hope that if they hear the same reports repeatedly they will take notice.
If your telephone is unlocked (and if you are on XDA chances are it is), flash Franco's kernel. I did it today and now my problems with WiFi are gone. Plus Franco's is known to be very battery efficient. It's a win-win situation.
