[Q] Carbon rom Question - Nexus 10 Q&A, Help & Troubleshooting

Nexus 10 here. Just installed latest carbon ROM to test vs PA- couldn't see my 5 GHz network. Anyone else? Back to PA for now.

You should ask this in the carbon rom thread...

Not allowed, new member.

Liquid rom as well
No 5 GHz support on any of these ROMs... Am I missing something? Stock and paranoid are the only ones that see my 160+ channel.

Crazy question:
Do you check tick at wi-fi setting Frequency band on Auto or only 5Ghz?

Do some research on the channels there is a glitch with certain channels not working on 5ghz

Your right. It was set to Europe. Had to change to USA and reboot in order to see my 5 GHz. I'm a dummy.:silly:
Could only connect at 130Mbit on 5 GHz no matter my settings. Guess I'll stick to Paranoid until those issues are settled (300Mbit steady).

[Q] [Solved] CM7 + Kindle Fire = no 802.11n?

Hey everyone!
I have installed CM7 onto my KF, which I am loving btw, as directed by whistlestop over at http://forum.xda-developers.com/showthread.php?t=1390773, but I notice that my KF cannot find my 802.11N network. However, my 802.11G network is working w/o any problems.
I have searched that thread and the entire xda forums and could not find anyone commenting on CM7, KF and 802.11N. I am just wondering if the feature has even been added yet to the build or if I have a problem.
Much thanks for any info!
Has no one have any observations on this? I see the thread has gotten nearly 100 views, but no one is even able to confirm/repute my observations?

and your using CM7 on your KF? Can you tell me what band 2.4GHz, 5GHz or both you are using? Are you using a static channel or is it set to auto?
I ask because I had to set my 5GHz channel to a static channel for my Galaxy Nexus to see my N network. I am also using dd-wrt for my router firmware.
Thanks for the response!
there is a post from a dev that says 5ghz is not possible because the chipset is'nt capable of that - only 2.4ghz

Ya, mine was able to connect to my N network when it was running stock, but not since moving to CM7. In CM7, it doesn't even see the network.
just updated my last post ...

Thanks for the heads up! I also found a page on wlanbook.com after you mentioned it. I would post the URL, but not allowed yet.
As for seeing N network on stock, I realize I previously had my N network SSID extended to the 2.4GHz band as well as the 5GHz band, which I do not anymore.
Thanks again!
glad to help ...

[Q] WiFi radio

So I'm asking this question to find out more info about WiFi radio, is there ?? and what does it do, I was on stock MT4g and had both 5 ghz and 2.4 ghz bands from my router on my phone, and now I get only 2.4 ghz band with this rom, and I have tried many roms lately and none work like the stock rom....
so can you flash a different WiFi radio or not, and where do you find them
There is no "WiFi radio". There are WiFi drivers in the kernel.
You change them by changing the kernel.
And I guess that the custom kernels out now for MyTouch 4G don't support 5GHz bands.
This question was discussed here recently. With Cyanogenmod 7.1 and standard CM7 kernel I do have 5 GHz Wi-Fi supported.
Btw, it is believed that lack of 5 GHz is somehow related to Sense Framework, and not to custom kernels. So in Sense-based ROMs you don't see 5 GHz Wi-Fi, while in others do. Of course this conclusion might be invalid.
Sense has a different line of kernels from CM7. Those kernels aren't interchangeable, and I don't know how many drivers do they share. Possibly that difference is responsible for the lack of 5GHz support.
Official MySense 2.3.4 supports 5ghz, I believe. Have you tried flashing it?

Are you sure, i was assuming it was on the hardware side...If that is so there is nothing you can do to get the 5ghz band
Hardware does support it. I saw a thread where someone posted that after getting the GB OTA they all of a sudden got 5ghz frequencies. Someone responded by saying the chip always supported it, but there was no driver in the kernel. That TMoUS must have added the modules into the new kernel.

I am having a similar issue with my wifi on my mt4g. My issue is that when i go into my network settings and turn on my wifi, it doesn't turn on and my settings is then put into error and force closed.
i was wondering if anyone else had similar issues with this. after hours of research i have come to the conclusion that it may be a hardware problem.
if anyone knows how to fix the wifi hardware on the mt4g please reply.

Wireless 5ghz problems

The Nexus 4 cannot see my 5ghz wireless network for some reason. Anyone experiencing this problem? I have restarted the router and it is set to 20mhz but the nexus does not see it. It works fine on my other Android phones.

Perhaps try a different channel. Some devices can see a certain channel while others can not. It's worth a try.
Go to Settings, Wi-Fi, click on the 3 dots at the bottom right corner, Advanced, Wi-Fi frequency band, is it set to Auto or not?
Turns out the Nexus has a very limited selection of channels. Anything above 5.240mhz is not seen. That's really strange when others phones almost 2'years old had no problems. Still trying to decide if I should keep this phone, not a fan of the stock experience over htc sense.

I highly doubt that. Stock Android does not even have a T9 dialer and the widgets are but ugly compared to sense.
My N4 sees my 5ghz wireless just fine..
And Sense is bloated and ugly to some people as well. If you prefer sense then stick with it. No one is forcing you to have an N4.

I already confirmed that it can see the wireless signal when on a lower channel. I'm just surprised at how featureless stock Google is compared to others. I mean n it does not even have a t9 dialer

Everything that Sense gives you, you can get with apps from the play store. Most people that have already owned a Nexus phone know this. Also most of the time stock Android is faster then Sense. If you want a HTC phone get a HTC phone. People don't want to you hear you complain about how bad stock Android is. There are people that are dieing to get the Nexus 4 because of stock problems. When it comes to the 5ghz chs., my Nexus 4 plays fine with my D-link dual band router. Just lower the channel down.
Bands
So I spoke with someone at work who is our network engineer for the wireless portion of our network, and he told me that most devices can only use the upper and lower ranges of the 5GHz band. Apparently the middle of the band, channels 52 - 140, can receive interference from nearby airport radar. The current setup at work uses channels 36 - 48, and 149 - 161 and skips the large portion in the middle. I haven't had a chance to test this at home, but looking at my router settings really quickly, it doesn't appear that you can set a range of channels to use using DD-WRT (DD-WRT v24-sp2 (08/07/10) mega). The other day I did confirm that channels 36 - 52 worked on my phone, so tonight I can test if the upper channels work. Just looking at the network here at work though, the phone sees the upper range of channels.
Totally bumping this topic to say I can confirm setting your band lower than 5.240GHz works. I set my band to 40 (5.200GHz) and the channel width to 40MHz and it sees it and connects to it just fine now. For future reference, if anyone searches.
I was using 149-153 and works just fine as well. That's closer to the 5.7Ghz ranges. The middle bands are not allowed in some countries so depending on which you are in your phone will not turn those on.
Wikipedia has a nice chart of available channels:
http://en.wikipedia.org/wiki/List_of_WLAN_channels
I think the DFS (Dynamic Frequency Selection) channels are also blocked.
I think the Nexus phones use SIM carrier country to decide what channels are available.

[Q] 5Ghz WiFi, Galaxy Tab 2 7"? (GT-P3113)

I've been scouring shopping sites and odd forums, and for the life of me it's proving difficult to find a newer-ish (relatively inexpensive) tablet that has 5Ghz support.
So far, the only tablet I've actually come up with is this one (GT-P3113), but I've been unable to find if anyone can confirm the 5Ghz radio working. I saw one forum thread that mentioned issues with higher 5Ghz channels, and it's got me worried. Has anyone had any experience on this? Stock ROM? CM?
Thanks in advance.
B G N only no 5ghz
Are you certain? Quite a few places (and forums) suggest that model has a 5Ghz radio
To list a couple..

Are you running stock ROM?? From what I've read the 5ghz radio can be enabled with root, but I'm curious to see if it works in CM or not.

From what I've read 5Ghz wasn't enabled from ICS on. Something to do with the availability of 5Ghz in Europe. I've seen several guides on how to enable it on ICS at least, but I can't test it since I don't have a 5Ghz router. Here are the two guides I've seen on it. I'm almost sure you'd have to be rooted to do either.

I'd probably go for CM10(.1) straight away, which is why I wondered on if it's enabled in there. Luckily for me, CM is opensource so I can just go look and see if it's enabled in those files lol.
Thanks for the help, much appreciated.

awesome! Did you have to do anything post-root to get it working? IE did you switch from stock rom, or did you need to modify any wifi-config files?

Yes ,lucky its open source except for the proprietary bits that you need from hardware vendors like the wifi and GPU drivers and several others , just like the open source Samsung stock ROMs.

Neither of these work to enable 5 GHz on my GT-P5113.

I believe you are right in that the Kindle Fire HD has a 5GHz radio, but I'm looking for a more pure Android experience, google play and what not. I know there are methods to getting Play Store on the Fire HD, but more specifically I'm looking to go CM with the tablet, and I'd rather run the Samsung for that if it has a working 5GHz radio.

Nevermind. My noobness is showing

hey guys,
i have been baffled by this too when my gt-p6800 upgraded to jb, it lost the capability to access my 5GHz-N wifi. i tried going back to ics and i had access back to the 5GHz wifi. however, ics have had its problems (wifi disconnects when the tab goes to sleep) and eventually i went back to the jb: no 5GHz wifi but wifi is stable and doesn't disconnect.
earlier today, a friend of mine with p3100 on jb visited me at home. his tablet wasn't able to detect my 5GHz wifi too.
interestingly, my very old p1000 on gb can still access the 5GHz wifi.
is it now safe to say that tablets with jb have problems detecting and accessing the 5GHz network?
regards to all!

Router suggestions for N4

Greetings,
I'm planning to purchase a router for my office and I'd like to use it for my N4 via WiFi.
What specs should I be looking at?
Is there something I should consider (bands, frecuencies, etc.)?
My connection is not that fast, only 1.5MB.
Please share your experiences. It'd be truly appreciated.
For the best speed it should be N and 5GHz.

Wireless routers have different standards that they go by. As of right now for consumer use, there are B, G and N. B & G have been around for quite some time and N has had some time to develop to the point where its the fastest standard available currently.
So basically, you want to see if the router you are purchasing supports the wireless N standard. Chances are if the router supports N it will support B and G as well...

That is for 300 mbps, there is a section for 150 mbps. My guess for the difference is obviously the speed, but that difference in speed will most likely affect the price as well.

I'll contact a few stores here. Thanks again for all your help.
By the way, the person that replied first recommended 5Ghz but most of the TP-Link options I've seen in that page you linked show 2.4-2.4835Ghz. Would that be enough in your opinion?

The frequency is to circumvent interference. For example, a lot of home phones operate on the 2.4 GHz frequency, which is probably why the first guy who posted recommended 5GHz, so you could have a dedicated frequency for Wi-Fi. If you can get your hands on a 5 GHz router, then go for it, but if not a 2.4 GHz router shouldn't be a problem...
