Regulatory Domain - EVO 4G General

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?

Wifi help please!

Was wondering if anyone could help me.
I was loving almost everything about my elocity tablet, but wifi issues were same as initial g tablet.
Firmware came out yesterday that supposedly fixed this and for everyone in the main Elocity thread, it seems to have just done that.
I have applied it but have the following problem:
While I can see all the available networks, I cant seem to join any unless I am almost 5 feet from the router and despite seeing excellent signal I am only getting 1 mb/s link speeds. Rarely it wil go as high as five.
It is not a router issue as laptops and iphones connect fine. I have rebooted router and tried every permutation of wireless secuirty and wireless speed, b/g/n settings (the elocity is b/g only wifi). With no luck
Went to local McDonalds and could pick up 4 surrounding wifi networks with good to excellent signal and connected to them but again only a best of 1 or 2 mb/s.
I will be returning my device on account of this. Being in Canada I won't be able to get another (I am in USa with family for holidays for another week.)
I am hoping there is something in software I could do that might fix this as I like the device otherwise especially with quadrant scores in the 2400 range now.
I tried resetting the device and reflashing the firmware update to no avail. I don't know enough about android or linux to know if there is anything I can do delving deeper into the device to fix this?
It is almost like it only connects at wireless b and not g working so range is short and slow.
any thoughts or ideas before I send back as I have 2-3 days to wait for the RMA label.

[Solved] Cyanogen Wifi connectivity issues (all models)

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

[Q] Some apps can't connect using wifi (but can using 3G) on my Motorola Defy

Hello,
If you don't want the boring details of how I discovered the problem feel free to skip the next couple of paragraphs and go straight to the technical details.
I got my first Android phone (Motorola Defy) a couple of weeks ago and at first I was only using it with wifi because my data plan wasn't activated yet. While playing with it a little I realised that I saw a lot less ads than my boyfriend on his 6 month old Defy. I thougt it was weird but, well, seeing less ads is not a big problem.
Then when I got my data plan I saw that when I wasn't home I saw a lot more ads, so I began to suspect it had to do with how my phone was connected to the internet : wifi or 3G.
Next I wanted to try out Astrid and when I tried to log in using my Google account it failed repeatedly. Until I disabled wifi and it logged in fine using 3G.
Then I installed RTÉ DocOnOne to listen to documentaries while falling asleep. When wifi is enabled, it cannot start up because it can't connect (network timeout). Over 3G, no problem.
At first I thought it was my router blocking ports or something but it happens with different wifi APs and more importantly my boyfriend's phone, connected to the same access point, loads everything without a problem.
Let's sum up:
Some apps can't access the network using wifi but work fine when using 3G.
It happens regardless of the wifi AP (tried 4 different ones with different routers) and another phone using the same app connected to the same wifi AP can access the network just fine.
If I initiate the connection using 3G then switch to wifi (typically I launch the app with 3G, switch wifi on without closing the app), it still works after that (RTE DocOnOne has no pb streaming the documentaries once it has launched)
My phone is a Motorola Defy, French retail ROM, not rooted, no motoblur account (skipped the configuration), Froyo 2.2.2 (already on the phone when I got it), system version (if that means anything to you) Version.34.164.3.MB525.Retail.en.FR, kernel 2.6.32.9-g050ccf2, build 3.4.2-164
I can't give as much details about my boyfriend's phone (that doesn't have the problem) because he's not here right now but I can tell you that it is a Motorola Defy too, French retail (I think) ROM, Froyo updated from preinstalled Eclair (using the official Motorola update), not rooted, with a motoblur account
I have no idea if that's relevant or not, but my phone has the "google maps 5.7.0 crashes on Defy" issue (18446 in the android issue tracker) and my boyfriend's phone hasn't.
Has anyone encountered this issue before ? I couldn't find anything on this forum or with a google search.
Is there any tool I can use to try and find the cause of the problem ?
Thank you for reading all this, sorry if my message was long but I wanted to give as much detail as possible to help the nice people who may find what is wrong with my phone
I didn't read all..
but if your phone don't have problems then check this:
1. go to settings
2. Select "Location & security settings"
3. enable this "Use wireless networks" Location determined by WiFi and/or mobile networks
4. test does it work...
Hello manumanfred,
I did what you suggested (actually it was already checked) and the problem is still there (tried unchecking it too).
I am not sure why you suggested it, was that related to some phones having wifi problems in some countries ? I read a thread about that when I was researching my problem but it is different. In my case, wifi works most of the time, but some requests always time out.
Thanks for trying
Anyone else has an idea of something I could try ?

Hello, did you solve the issue?

Wi-Fi channels in Sense ROMs - LACKING!

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.

[Q] ***PLEASE READ*** Poll- Wifi/DNS issues caused by Nexus 7 2012 4.4 ?

Mods--I think due to the nature of this possible fundamental issue, it should be posted in the general section as well as the Troubleshooting forum area. Especially if it is affecting other devices in our homes...but if anyone disagrees, I apologize ahead of time if you feel the need to delete this. Otherwise sticky it!!
Full disclosure. I have the 4.4 160 update, not the very final patch that came out right after it, so it is possible that the patch secretly solved this issue. Also, I just bought my Nexus 2012...so I have no experience with 4.3 or 4.2.
I have an Asus RT66U router with the latest Merlin build and NO issues at all for months and months. It is commonly known to be the best router on the market (so is the AC version) . I have super finicky intermittent internet streaming on the Nexus 2012 Android 4.4, with YouTube buffering every 10 seconds and wifi signal boosting and dropping strength (it seems), but not disconnecting. I also had all of my other devices stop working around the same time I bought the Nexus (within the day I connected it).
I found a very interesting link as well-
http://productforums.google.com/forum/#!msg/nexus/PjerorpdZMA/LIJA7cToUiYJ
Right after buying the Nexus, I had to go into my router and change it's naturally acquired (by my provider) DNS, and put Google's DNS in place. I thought maybe the provider was having a DNS outage....I haven't put it back since then. But now I wonder (and I will check tonight).
So...here is the poll-
How many people, that have any wifi issues, are also having DNS issues?
Do you think this is a ROM issue.....in other words....did it happen with 4.3 or 4.2 to you?
Edit: Also I have heard of people disabling the NFC and taking off the back cover and reseating the wifi module (that is popped out a bit) and solving this issue... or changing the SSID, channel and password.
