I wish I could post this in the dev thread(s), but alas, I haven't posted enough on XDA yet (I spend most of my time over at RootzWiki).. So sorry about that.
My issue: I'm currently running safariking's 2012-05-27 build of CyanogenMod 9, but I also encountered this on kallt_kaffe's 2012-05-17 build. If my "Wi-Fi frequency band" setting (in Wi-Fi --> Menu --> Advanced) is set to "Auto," I can't see any 5GHz networks.. but if I set it explicitly to "5GHz only," I can see (and connect to) them. The issue with this I'm also running CyanogenMod 9 nightlies on my Galaxy Nexus and the "Auto" setting works as expected -- It shows both 2.4GHz and 5GHz networks. Does anyone else experience this behavior?
yes i have the same issue, i wanted to start a thread for this today, you were faster. I hope kallt kaffe have a lokk in this thread otherwise i will post it in the dev section.
+1 here
didn't mind as long as it connects to my 2.4 ghz :]
i realized yesterday that this bug is fixed. my p7310 shows both networks and can automaticly connect. i have cm9 from 29.6

I think I may have found a difference between hardware rev_10 and rev_11, and I'd like to ask for some help in either proving or disproving my theory.
I have two rev_10 N4s here, and I've noticed both do not see and cannot connect to WiFi networks operating on channels 12 and 13.
I mentioned this to someone a different forum, and after exchanging a few posts and screenshots it became clear that his N4, a rev_11 device, was able to connect to networks on channels 12 and 13.
So the question I'm asking is: Which hardware version do you have, and can you see and connect to WiFi networks on channels 12 and 13?
The only thing I'd point out when testing is to make sure the network is only operating on one channel as it will likely still pick up two-channel networks on the other channel.
Thanks in advance.
My Nexus is rev_10 and can connect to my wifi router in channel 13 without problems.
I had a problem at the begining because my SSID was hidden and I need to unhide it in order to connect. But I solve it with a market program called "Hidden SSID Enabler" that allow me to connect to my hidden SSID again without unhide it first. But I use always channel 13.
i had some issues with it yesterday.. that suddenly wifi vanished off my nexus but was working on my gtab10.1
is this anything to do with the wifi issue u mentioned here

I connected to my hidden network without any issues... You just have to "add" the hidden network. Also r10 here.

It might be a regulatory issue and this isn't uncommon. For some reason the Rev 10 phones may think they are in a different country, and are in a country which is forbidden to use bands 12 and 13. Do these phones have SIM cards? It might be the SIM card/network that the phone uses to confirm the country for radio connections.
I've a rev 10 and I am on band 13 no problem.

I kind of suspect this too.. WiFi reception is pretty weak compared to my s2 running cm 10.1 on the same location in my apartment. But doesn't really matter...

I have a nexus 7 and a rev 10 nexus 4. They both work fine on Wi-Fi. What do you mean that the nexus 4 isn't working well compared top the other device? Are you just going by the meter?

Hi mate I have the same problem than you. My nexus 4 rev11 cant connect with a wifi network in channel 13. And my old Htc Desire works fine.
I've had this exact issue with my N4 I received last week. Mine did actually work but only if I left it alone for several hours. Once ti connected, it worked well and was stable. If I restarted my WiFi or restarted my phone, the problem is back unless I wait several hours!
Then yesterday, I changed my wireless channel from 13 to 8 and voila, instantaneous connections much faster than my iPhone 4. It seems like the wireless receiver in the N4 is of a lower quality compared to other phones.

Relax dude. No WiFi hardware change from rev_10 to rev_11.
How do I check what rev I'm on?
I've got a Rev_10, no wifi issues at all with my phone. In fact, it gets better signal than my plastic backed Asus Transformer, and my old S2.
We need more people with rev11 to try the bug please try it!!
Put your wifi AP in channel 13 and try to connect the nexus to the network,
Edit: Same problem with channel 12 seems that all the Nexus have the USA wifi policy
Well I think it that apart from policies nexus has software issues related to WiFi just like BT.Its simple we are bug testers for 4.2.1

I have same problem with Nexus 4 rev 11 device with Android 4.2.1
channel 13 & 12 broken
Most likely your 12-13 bands are disabled... I remember something from other phones I had where you could enable the non-US channels?

Maybe someone can try following this thread. It was for the Icona A500, but it looks like all they're doing is changing wifi_country_code to EU in /data/data/com.android.providers.settings/databases/settings.db
Yesterday I get the 4.2.2 OTA and now I can connect with the wifi channels 12 & 13.
How do I find out what revision I'm on?
I've been having some problems too with my Channel 13 wifi. My regulatory area was set to Europe (there was no narrower option), and I assure you it's more than legal to use Channel 12 and 13 in my area.
My Nexus 4 kept dropping off the network, and when it did so, the SSID would disappear from my phone's list. My desktop, which was less than a meter away, was still working fine. I had to restart the phone's wifi each time this happened.
I figured it was my ISP's router being dumb at DHCP (the phone's IP was assigned in that way) so I replaced the ISP's router with one of my DD-WRT routers so that I could better log the issue. Still had the problem. At first I wanted to start logging what was happening, but then I remembered the oddity about my network being on Channel 13.
I switched it to Channel 1, all problems were solved.
How do I find out what revision I'm on? I'm currently on CM10.1.0 RC1, which is supposed to be based upon Android 4.2.2.
Stock 4.2.2 here, 306K device (Rev_11) - managed to see & connect to Channel 12/13 only if switched the frequency from "Auto" to "2.4Ghz only" (or from "2.4Ghz only" to "Auto") in WiFi advanced options menu.
It amazes me how Google let us wait for months with these broken wifi/bt drivers. Hopefully 4.3 will fix these.
I got my OnePlus 3T a few weeks ago and love it. I am on T-Mobile and Wifi calling seemed to work fine on the latest release of OxygenOS (I basically have no cell reception at my house). Today I flashed CM 13 using Sultanxda's custom ROM and am SO HAPPY with it so far, except that I can't enable Wifi calling even though I can search for the setting and toggle it on; whenever I go back to the setting page for the option it's turned off again. I believe this has been discussed at length on the OnePlus 3 forums. My question is for any CM developers who may be working to bring CM 13 or 14 to the OnePlus 3T: since OxygenOS on the 3T now seems to support Wifi calling, is the outlook any better for CM supporting the feature on the 3T anytime soon?
For any other ROM developers, same question: will your project be able to support Wifi calling in the near future?
Thanks!
Bumping this since no one has had the chance to answer yet.
Since the Redmi 8 don't have 5ghz Wifi capability we are stuck with 2.4ghz wifi and on my 2 Redmi 8 devices with Bluetooth enabled that kills the speeds to about 5mb. Apperently Bluetooth and 2.4ghz wifi run off same hardware or software and don't appear to play nice together..
I use multiple different wifi connections a day and was a problem for me. Anyway so this was the workaround that fixed the problem for me and my device. Pretty simple and straight forward and suppose it could work on other devices with same issue..
Always only try this at your own risk.. *As Root is Required*
First off: I'm located in Canada, could be different in another region.
I have a unlocked bootloader
latest stable Xiaomi.eu rom for the Redmi 8 installed
Official TWRP installed..
2: *Root Required*
Download and Install latest version of Magisk and flash via TWRP
3: Download and install Service Disabler from Playstore and Grant su permission after opening the app .
4: Search for Google Play Services and click on that .
5: Scroll down the list till you find NearbyMessagesService and click it to disable it permanently.
6: Now Make sure you have Google's "Nearby" functionality disabled
Go-to your Google account - Device connections - Devices - Show Notifications off.
Now back to settings - Passwords and security - Location - Scanning - turn all off
And reboot.
Now my other device is on stock MIUI and I haven't tried this on stock rom as of yet. It's my wife's device so if she lets me I will test this on her device as same issue is present.
In time I will try to see if this "fix" will retain if I unroot the device after..
*Update* this will continue to work if you unroot device.
*Update* when I installed latest Xiaomi.eu rom 11.0.10 sometimes it don't work till I reboot. Not sure why yet.
thanks for sharing
but for me I just changed the Channel used in my router and everything works fine

try channel nom 10 or 11
guys you have slow wifi because your wifi and bluetooth are using 2,4ghz they interfere with eachother you need to download an app like wifi analyzer and go to the last tab then look which channel isnt used and use the channel which isnt used i hope i helped you
without root is there any fix?
Yes WiFi and Bluetooth in same frequency range but that should not cause problem. My mi 8 lite manages to communicate with my mi band 3 and use WiFi ok. I had an ulefone and that worked ok. I had a blackview and that worked ok. The redmi note 8 pro did not. At first I thought it was maybe a bad chip that was leaking so tried another with same result. So its hardware related or software. But it's not the fact of both using same frequency band. As Bluetooth is not as strong a signal I would have expected that to drop not WiFi.
Xiaomi should have sorted this by now. Miui 12 still hasn't fixed this.
Fix for home wlan use

This is a big problem and Xiaomi should fix in the next update!
However if you mainly use Wifi at home, change the wifi frequency to 5ghz and the problem is gone.
In my modem/router you can do separate 2,4ghz and 5ghz networks (both work at same time), so my Laptop and Xiaomi phones are on 5ghz (a lot better speed in both) and old hardware are in the 2,4ghz network.
Didn't know this before, but now also my laptop wifi speed came from 30-40mb-> 120mb.

Are you kidding me? Well, what a waste of mobile I have bought ... everything is fine except for something as important as connectivity. Ok Xiaomi ... Does anyone know of any ROM that this failure does not pass? so far all the ones I've tried happen the same ... :crying::crying:
I also tried the proposed fix (on latest Stock rom / Android 10) and unfortunately it did not work Any other suggestions how to solve this extremely annoying bug?

Install a custom rom like HavocOs
I have the solution ===>>> youtu . be / WMksEEKXlJY
The problem is interference with Wi-Fi and Bluetooth Scanning.
DISABLES THESE TWO CONFIGURATIONS
On MIUI 11:
SETTINGS >> Passwords & Security >> Location >>> Scanning >>>
Wi-Fi scanning> (OFF)
Bluetooth scanning> (OFF)
On MIUI 12
SETTINGS >>> LOCATION >>> Scanning >>>
Wi-Fi scanning> (OFF)
Bluetooth scanning> (OFF)
This will solve the problem of drops in the wifi.
It is NOT POSSIBLE to use Bluetooth in conjunction with wifi. But with these settings disabled, you can use wifi with better quality (as long as Bluetooth is disabled).

Thanks. I watched the video, but unfortunately it is not in English, so I didn't really understand what the actual solution is. For me it seems, that your main "trick" is to switch from 2.4GHz to 5GHz WIFI, is this right?
Would it be possible for you to write a short manual on your steps here in English, that would be great!
Thanks, Lars

Have already disables these options, but was hoping to be able to use Bluetooth in conjunction with WIFI, since my smartwatch is always connected to the phone by Bluetooth
So unfortunately no final solution for me :crying:

Thanks for the suggestion, moving from channel 6 to 13 did the trick! I can finally watch videos with Bluetooth speakers.
Would Xiaomi.EU fix these issues? If so, I'll aim for that ROM!
Anyone else having wifi issues after the Android 11 upgrade on their Pixel 4 XL or similar? I have the latest eero pro's (for now) and had zero wireless problems before hand, but since, my wifi will randomly drop as well as drop between mesh handoffs.
