Hi
I have problem with 5 GHz wifi. Phone won't connect to 5 GHz band on any router. It just doesn't see any router when I manually choose 5 GHz.
On automatic it connects only to 2,4 GHz and I can manually choose 2,4 GHz.
I have installed several custom ROMs and original to. Only one time it worked with 5 GHz, with one version of miglobe ROM.
When I bought the phone it came with global developer ROM and wifi worked fine, 5 GHz no problem.
I've unlocked and installed TWRP, 5 GHz worked fine.
When I first time flashed different ROM via TWRP, 5 GHz didn't work. After several flashed ROMs I've flashed mi.globe ROM and then wifi did work in 5GHz band. I think the version of android in that specific ROM was 7.0.
I'm curently on global dev ROM MIUI 9, android 7.0 flashed via fastboot. I've lost TWRP but anyway 5GHz wifi still doesn't work.
I've read somewhere that when downgrading android version there can be issues with wifi, bluetooth etc. I did downgrade from 7.0 to 6.0 in the process. But also I did upgrade from 6.0 to 7.0 I am on currently.
I've posted this issue on official MIUI forum but no one replied.
Does anyone know what is the problem? I don't think it's hardware fault, only software.
You could try flashing the new kernel that's floating around.
I've never had such issues, 5GHz worked flawlessly for me from the start.

Hmmm... I've never done that. I'll look into it. Thanks.
I'll wait for now. Maybe someone else knows what is wrong, what I did wrong maybe...

Hi everyone.
I just upgraded my xoom to rooted 3.1 using the guide in this forum.
After the upgrade my home network does not get picked up. I cant even see it in wifiscanner.
My phone connects to it just fine, and the network at work is detected by the xoom no problem..
Any ideas?
I already tried to flash the overclock kernel to see if it was a kernel issue... still the same problem. :/
nevermind
Turns out that 3.1 does NOT support wifi on channel 13.
Moved my home network to channel 11 and everything works again
Note:
Windows 7, Android 2.1, Android 2.2
They all mysteriously support ch13 networks.
Can anyone confirm this?
If so; maybe someone should inform the kernel guys
Hello fellow developers,
I am having a problem with my custom rom. I was using FoxHound previously but their latest update i.e 1.9 didnt quite impress me, with much more battery drain than 1.7 and 1.8. Anyways I shifted to PA 2.54 now, but the Wifi does not detect any wireless other than the one in my room and it doesn't connect to that too, it asks for authentication, accepts but they nothing. It says "saved, secured ......."
earlier I had MIUI too, no WIFI problems. I installed stock JB today and it still had an issue but after a hard reset everything was fine. I flashed my phone AOSP too today, the same WIFI problem was there.
Any help?

Hi all -
I recently updated to the 4.4.3 VzW firmware and upgraded from Viper 1.8.0 to Viper 2.5.0. Since upgrading, I have been having troubles with my hotspot. After being on and other devices have been using it for a bit, my M8 begins to rapidly turn on/off the Data Connection. This doesn't stop and the only way to fix the problem is go into airplane mode and back out again. I figured that I may have had a bad flash, so i tried reflashing clean downloads of both the firmware and a full wipe and reinstall of ViperOne, but still seeing the exact same issue. I seem to be also experiencing a problem where my phone is reporting a 4G connection, but data is disconnected and i cannot get anything over the data channel. Voice works fine. Again, to fix it's a cycle through airplane mode.
I tried applying the changes recommended by for the 4G handoff fix, even though the problem described does not seem to be exactly the same as mine. It did not seem to help, and mae it even harder to get a reliable 4G connection.
http://forum.xda-developers.com/verizon-htc-one-m8/general/verizon-4g-handoff-fix-t2868778
Has anyone else seen anything like this and have any recommendations for a fix?
Just realized this would be better in the troubleshooting forum. Is there a way for me to move it there or does that require a moderator?

I have had the same thing, going back to 1.55.605.2 FW does seem to be the fix, I think its something with 4.4.3 FW.
One of the so called improvements is Mobile hotspot connectivity, but maybe that's only with phones that don't use the patched default.xml,
the ones that really pay for the mobile hotspot.

Thanks for the reply - do you have a link for the old firmware, so i can flash and revert back to that?
Also - are you still running Viper 2.x or did you roll back to a prior ROM as well?
After some more searching, i found this link for stock 4.4.2 on VzW, but was wondering if anyone has the firmware only, so don't have to restore recovery, and rom afterwards.
http://forum.xda-developers.com/showthread.php?t=2727831
I certainly can and will do it, if necessary, just would prefer to have the firmware only, if someone has it available. Anyone?
Thanks in advance for the help!

Thanks, downloaded and reverted. Long boot times, but things working. Now to give the hotspot a few tests. I'll update with my results.

initial tests are very promising. hotspot seems to be stable and hasn't dumped the data connection yet. Looks like good old VzW managed to screw up the firmware update as usual. Would be nice if they didn't always to be different. Thank god for these forums and the hardworking devs here!
I spoke too soon. Still seeing the same issue after reverting the FW back to 1.55.605.2. Anyone seeing this? Any thoughts on if reverting back to Viper 1.8 would help?

I don't think it is the firmware that is the issue, I think it is the kernel. You should be good going back to Viper 1.8 as it uses an older kernel. I would think you would also be fine using the newer firmware and an older ROM version.

I'm starting to believe this as well, that there's something flaky in the 2.x Viper ROMS for VzW and hotspots, and likely in the kernel. I've already reverted back to the old firmware, and I'm going to go back to a clean 1.7.x full install, then OTA to 1.8. Will update with the results.

Any luck fixing this issue?
I'm on the latest 23.3.24, unlocked bootloader and rooted. I've been experiencing problems with Bluetooth not working at all and wifi as well on the 2.4ghz band. Can't pair with any devices and wifi only works on the 5ghz band. Wifi hotspot will only work on the 5ghz band as well. Have tried using different baseband radio firmware and different roms, full wipe, and updating to the latest stock rom. Still having issues. I have a feeling it has to do with the hotspot entitlement hack I used posted by Topsnake, since thats when I started having problems. Anyone know what else I can try to resolve this?
Remove the entitlement hack and all is good
CM12 Inside DROID Ultra
Even after completely wiping the phone and installing latest stock rom the problem persists. I'm now using iKrYpToNiTe's app for bypassing entitlement check:
http://forum.xda-developers.com/moto-x/themes-apps/app-hotspot-entitlement-bypass-v1-1-5-9-t2705152
Should also note, checking bluetooth and wifi were the first things I tried right after wiping and installing the latest rom, and I'm pretty sure whatever changes topsnake's hack made were cleaned out with a system wipe.
I have no service and no cellular network problem on my N5, running dark rom 7.1.2 aosp, with franco kernel ( never had issues before ), newest radio and bootloader. This started happening when i got my new sim card from my provider and i got 4g signal in my area for the first time. I tried manually selecting radio by going in the hidden menu by entering *#*#4636#*#* and i got lte and full bars signal after selecting band 8 ( 1800 hz ) but only for a minute then it went back to empty triangle. Tried selecting 3g only in preffered network, tried manually selecting provider, tried toggling airplane mode on/off a bunch of times nothing works. Any suggestion would be highly appreciated, i love my N5 very much and i would hate to throw it in a drawer somewhere. Thanks in advance
Flash back to a stock ROM and test it worth your new new.
Does the sim work in another phone?

Were you ever able to get this rectified? I have recently been having this problem as well. I have flashed back to ROMs I was previously using and flashed back to stock to no avail. My SIM card works in other devices as well. I really do not want to have to drop on a new phone, but I have tried every solution I have found online to no avail. I think it's fair to say that I am desperate right now.
edit: I found another thread on XDA that I'm looking into, I'll edit again if it works. I'm unsure how it took me so long to find that thread.
edit2: https://forum.xda-developers.com/go...getting-cdma-networks-to-nougat-roms-t3534679 is the thread that I found useful; I am now running Pure Nexus 7.1.2 with a full connection. Specifically, his second comment about installing 6.0.1 stock, backing up the efs, flashing the desired ROM, then restoring the efs is what ended up fixing it for me.

This morning it's not sticking with Pure Nexus, so I'll be trying DarkRom. I really don't want to use a CAF if I can avoid it, but it may become a necessity. Do people on T-Mobile have this problem?

So I've hit a point where I have 3G and nothing else. I can't yet get LTE to work. I'm using LineageOS CAF. How about yourself?

No luck with aosp by santosh m and pure nexus 7.1.2 , can't even get it to connect. I guess my last hope is caf based i will try lineageos caf. All i need is the efs backup from stock? If i can get it to work with 3g i will be satisfied because i did some digging and found out that my network provider which is Vip MK has no lte support for nexus 5 d820 ( my model ) only 3g, but i can't even connect with 3g selected. I guess because this one is for US frequencies it will not work whatever i try but i will give lineageos caf a chance.

I was able to get 3G only to work on my Nexus 5 by reflashing the EFS from 6.0.1; I'm trying right now to see if I can install PureNexus 6.0.1 then dirty flash to PureNexus 7.1.2 with any success. Also, I might just switch to T-Mobile, but I have to wait until later this week for that.
Hi,
LTE band 8 is not in 1800 MHz but first of all you can check your N5 model - US model is D820 and is not supported for LTE on 1800 MHz (band 3). For 1800 Mhz band you need D821 model.
Regards,

To clarify that:
You had the problem with not recognizing the sim or having no service at all. And you solved this by flashing the sstock 6.0.1 backing up the efs, flashing to Pure Nexus 7.1.2 and restoring the efs immediatley after flashing the rom (+kernel+root+etc)?
This solves this mysterious no sim/no service bug, which many (?) N5 owners experience? If this is true, I'd be really happy

It didn't stick. After I lost it I was unable to get it back. I gave up and switched to T-Mobile, where it is no longer a problem. Apologies for not having more testing information. I was able to get solely 3G on multiple instances, but getting the elusive 4G was beyond me.
I've had this problem before in two nexus, one of them running latest stock and the other a customized ROM. I tried to flash a stock ROM image in both of them with no luck. I was pretty sure that the image I was flashing was the latest, so the radio & bootloader should be flashed to the latest versions. But it didn't worked.
Finally I found on a XDA thread where someone was posting only the latest bootloader & radio to flash. I did it with NRT (in Advanced Utilities) and it worked:

I can't remember or find the thread, so I post the images here:
- Bootloader-hammerhead-hhz20h.img
- Radio-hammerhead-m8974a-2.0.50.2.30.img
I think I had to flash them twice because the first time it wasn't right, but there were 4 months since then and still no failure

Thanks for your input. I'll check that when I have some time. This is really weird as it looks like a hardware problem but if you can fix it with this method it's clearly a software issue...
