[Q] 5GHz wifi and AOSP - Galaxy S 4 Q&A, Help & Troubleshooting

My i9505 has been misbehaving when trying to connect to 5GHz wifi since the 12th of October, when I flashed the then-newest official Cyanogenmod 10.2 nightly; before that it had been working with any problem on those same nightlies. Something must have been introduced between then and the 2nd of October; I didn't do any flashing during that time as I was abroad on business, so I'm not sure exactly when the change might have been introduced. Since that time I've moved to a 4.4 ROM but the problem persists.
It seems that I'm not the only one having problems with 5GHz wifi on AOSP ROMs - Google turns up various problems on different ROMs and devices. There are even suggested solutions such as editing text files in /system/etc/wifi or changing one's router's channel. None of these work for me.
The symptoms vary. Some of the time the device will simply refuse to connect to 5GHz networks. Other times it will connect and work normally for a time, anything from approx. 1 minute to 30 minutes or more (the latter making me think for a while that the problem is fixed). But, eventually, apps will stop getting a network connection and I'll be unable to ping anything. Despite this total lack of connectivity the wifi indicator will show that the device is still connected to Google's servers. Turning wifi off and on will start the cycle again, until I give up and switch back to 2.4 GHz.
This is rather frustrating and I wonder if anyone has any clue what it might be, or how it might be investigated further.

Has anyone else experienced this problem?

Yes, i have similar problem. i changed few custom roms, and nothing helps. First, it works normal, for few minutes, then wi fi go automaticly off, and then i cannot connect to wi fi network

I noticed this on 4.3 all versions, but since I updated to 4.4 official on my i9505G, the problem went away. I think it may be s bug in the NON-HLOS in the 4.3 roms .. official or otherwise.

I think it came in on 4.3, and I wonder why it is still affecting me on 4.4 as some people are reporting that has been fixed.
When official jfltexx CM11 nightlies come out I'll try a clean flash to see if there's any change.

I decided to try something similar - I updated to the latest UK firmware and then did a clean flash of an unofficial CM11 4.4.1. 5GHz Wi-Fi still doesn't work properly, as above.
I can get better results within a couple of metres of the AP.

[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] Package File is Invalid - No mentioned fixes working for me

I got my Nexus 4 today, and I've been pretty excited since.. So far, it's worked flawlessly everywhere except for when I need to download something from the play store.
Almost every download results in "Package File is Invalid"
I googled for hours, literally. I wiped data/cache of Google Play Store, Services Framework, wiped Cache from the stock recovery, and even factory resetted the phone to no avail.
I'm guessing it's a problem with my home's router setting. Everything works fine on my nexus except for the play store. Haven't gotten a chance to mess with other wifis yet, but can anyone tell me a way of fixing it?
If it doesn't work by tomorrow, I might run a custom ROM and try, though I really wanna stick with stock till 4.3/5.0 comes out :\
Any help?
Login to the Playstore from a PC and make sure your N4 is listed on your account. Also, try and install an app on your phone from there.
What happens if you try to install an app with Wi-Fi off (Mobile Data)? This could rule out an issue with your router or ISP.

It works fine on 3G for me. It's not a ROM issue since I tried it on stock, PA, and now CM10.1.
However, very small apps download without issues. I think the cap is around 5 mb above which the error shows up.
I'm 100% sure it's my router's settings that seem to be working against the nexus. Any idea what I could do?
I absolutely LOVE the fluidity of this phone (coming from a single core phone running a buggy JB rom) but this is killing me!!
The worst thing is, all the workarounds that I've read about since yesterday work for few, but not all people. And there are lots of workarounds. I've tried all that I've read but nothing's working :\

What router (Make / Model) is it?
Check for a router firmware update. If there are no updates or support, check if it is supported by DD-WRT.
Try doing a factory reset on the router, then set the security settings to (WPA2 only / AES only) and use the Android app WiFi Analyzer to find the best channel.

It's a DLink router.. No updates available
I reset it yesterday and put WPA2 but it hasn't solved the problem still :\
Wifi analyzer told me channel 6 onwards were good, so I tried 6 and 7 but didn't help either
I've had to download apk's for all the free apps to make it work as of now
I'll check with my mom and dad's phone to see if this problem exists for them too, but they're running gingerbread so idk if it'll mean much even if it works

First I would return to stock ROM. A custom ROM could have it's own WiFi issues.
As for the router, the only other suggestions I can make are;
test it in unsecured mode (open Wi-Fi access)
force 802.11G (disable B and N access)
lower the MTU from 1500 to 1480
disable uPnP
disable (or enable) WMM support.
disable any content filtering (like blocking java, proxies, etc).
Changing these options one at a time and see if any one fixes your issue.
Use VPN
Has been occurring a lot lately. Well, not a fancy fix but a simple one ..... use hotspot shield to connect and then all files install normally over wifi. Don't know why it does, but it works!
I have had "package file is invalid" issues with my Nexus 4 and my home WiFi connection from day 1 of owning a Nexus 4. I have tested it on 4 different WiFi Routers with different firmwares including stock and DD-WRT.
- Linksys WRT320N Dual Band (With Stock and DD-WRT Firmware).
- Linksys WRT160N V3. (Stock and DD-WRT)
- Tenda N60. (Stock "2012-12-12 V1.0.0.16_EN" and newer variants).
- ASUS RT-N66U "Dark Knight".
Tested 2.4ghz and 5ghz, varrious combinations of WEP,WPA-PSK, WPA2-PSK, WPA2-AES. It makes no difference the ONLY router from the above 4 that works correctly when downloading over WiFi from the Play Store is the Tenda N60 using the early release stock firmware "2012-12-12 V1.0.0.16_EN" that the router is shipped with. Even with the Tenda N60 if yuo upgrade the firmware to newer releases of stock firmware it will cause the issue to return.
Now this is an issue specific to the Nexus 4, I also have a Nexus 7, Samsung Galaxy S3, HTC Desire, Huawei Ascend G300. None of these devices have this issue using any of the router or firmware revisions. i.e: I can download from Google Play over the same WiFi connection with no problems.
I have had my Nexus 4 swapped for a replacment and the issue remains. So I've come to the conclusion that it's defintiely device specific the Nexus 4 has something inherently wrong with it..whether it's WiFi Drivers, Android Kernel, WiFi Chipset I dont know.
It doesnt affect all WiFi conenctions I can use my WiFi connectiona t work and the issue doesnt occur. It's strange that the cheapest router of the 4 I ahve tested i.e: The Tenda N60 is the only one that works consitently, I have never seen the "package file is invalid" issue using this router and Tenda firmware "2012-12-12 V1.0.0.16_EN".
This basically rules out any ISP, or WiFi security settingas as I used the same SSID, Security types and Network Key on the Tenda as the other 3 routers..
Poor show by Google, they obviously dont care about fixing this issue.
So your router having an issue is a Google problem? Well done coming to that conclusion...
For what it's worth, I have no such issues with my home router (Thomson) or my work WiFi network (no idea what router we have here but it's probably a Linksys/Cisco jobby)

Ermm...you might want to read that last post again, 4 different routers from different manufactuirers with different WiFi Chipsets (Linksys x 2, Tenda, ASUS) tested with stock and 3rd party firmwares all exhibit the same issue with the Nexus 4. Where as NO other android device or any other WiFi device on my network including a Nexus 7 with the same version android version as my Nexus 4 (4.2.2 ), connected via the same routers have any issues, even side by side downloading the same app from the Play store at the same time the others will suceed the Nexus 4 will fail the download "package file is invlalid" which sounds like a data corrption issue.
Co-incdecne thats it's only the Nexus 4 that has these issues ? I highly doubt 4 different routers are all faulty...especially since it's only the Nexus 4 that has this issue.
If you check the google code pages you'll find several other people complaining of the same issue.

All I'm saying is the 2 routers I use most have no issues and neither does the one my parents, my local pub or any of my friends. Might be a UK thing, I don't know, but I've never had a problem on WiFi at all...

I agree with that, maybe it's even a particular hardware batch of N4's, not sure. I can use my N4 fine on my work WiFi and other locations. Like I said it does work on my home WiFi if I use The Tenda N60 router with it's early release stock firmware, any firmware upgrades cause the problem to return though. But it cant be right that you should have to use a specific router and specific firmware which you cant upgrade without breaking the N4.
I've got another support case open with Google Play which they've apparently passed to their techs, lets see what they come back with... I have heard of someone with this issue using a custom ROM with a different Kernel to the Google stock build which includes newer Qualcomm Prima WiFi drivers (Paranoid Android) , they claim this fixes the issue for them.
Im relectant to flash a custom ROM and void warranty though for a basic feature that should work out of the box though.
I tried a lot of different things but nothing seems to have worked sadly.. I'm gonna update my ROM tomorrow to CM10RC4 and see if that helps, though I doubt it's the ROM's fault. Btw, I had the same issue with the stock ROM too
I've been having this problem whenever my portable wifi device connects to a slow mobile network. All my friends connect to my hotspot, but only my Nexus 4 gets the "Package file is invalid." error. For months, I've had to contend with switching to mobile data just to finish my downloads.
My only conclusion is that the Nexus 4 has a problem with slow connections over wifi by corrupting the data transmitted. It's fine when using mobile data.
Check this out:
http://forum.xda-developers.com/showthread.php?t=2300873
It requires the phone to be rooted. I'm already testing it out now.
I cant verify 100% yet but my Nexus 4 took the Android 4.3 OTA update yesterday. I have since tried several WiFi downloads over WiFI from the Google Play store and not a single one has failed !
So my intitial thoughts are that the Android 4.3 update has recolved this issue..and it was indeed a bug/fault in the previous versions maybe it's the new kernel, Qualcomm Prima WiFi drivers, New Google Play app... But whatever it is. It seems to have fixed the issue. Well done Google about time too !
The only down point is the denial of any issue their end from Google Play staff and blatant lies they tell customers about not knowing about such bugs.

Ironically, the 4.3 update on my Nexus 4 yesterday actually seemed to trigger the Package File is Invalid error, as it wasn't a problem before. MX Player and Jetpack Joyride are triggering this for me atm. Anyone else still have this on Android 4.3?

Having the same issues on all of my devices, but only while trying to download on my home wi-fi. Like the OP said, anything over 5mb won't download. Droid Razr M, Droid Razr HD, Note 10.1, Tab 2 10.1, and Nexus 7 (running 4.3), I cannot figure out what changed on my Belkin router (AC900) to cause this to happen suddenly. It was just noticed last night, and I have spent hours today trying to find a fix, and creating more problems to fix. If anyone has any step by step instructions of how to fix this, please explain to me like you would a 6 year old. BTW, rooting is not an option of all of these devices, so please make it a root free option. And I have cleared all caches/datas and done all the force stops recommended, as well as removed the google accounts and readded them.

Data dropping problems after 4.4 update

I have read many of the bug threads and thought if this were an issue for others it would have been a hot issue. With my nexus 4 since the jrt16o and s updates when I charge my phone up and then unplug it while connected to WiFi and then leave WiFi range to use data sometimes the data will connect and disconnect constantly until I restart the phone.
Also I cannot use 5ghz WiFi with the phone but I'm not too concerned with that. If anyone has ideas of what I could do I would appreciate it. I have flashed back to 4.3 and let the ota happen and still problems. Clean flashed through fastboot both krt16o and s and tried various Roms. Have also flashed back to the .84 radio with no change. I'm beginning to wonder if it could be a problem my specific carrier. I am with Tbaytel/Rogers in Canada.
Thanks.

[Q] 4.4.2 wi-fi issues

HI, I've got constant wi-fi issues on ma nexus 4 4.4.2. It certainly isn't the hardware, I got a replacement and the problem persists, which annoyed me cos all my photos cos messed up in order . anyway my wi-fi always disconnects and doesn't connect, this keeps on happening. im on a dual band router. is this only on 4.4.2? this problem only started happening in the last month or so. as far as i know it doesnt happen with other networks but when my wi-fi on my nexus drops, it doesn't drop with any thing else in the house. thank you
p.s. - i have a feeling it may be to do with something about the dual band. also the problem doesn't persist on my iphones, does this happen for you too?
was on paranoid android 4.2 beta with matr1x now on complete stock though

In your phone's Wifi settings, select either 5.0 Ghz or 2.4 Ghz and see if it helps. Also, try to search for Wifi fix by Kalo in the Development Thread and then flash it in recovery.

Wifi is unusable on android 10

Hi, I have a problem with mi redmi note 7 (lavender)
the problem is that the wifi gets disconnected at some distance (something normal from redmi note 7) the real problem is that it doesn't reconnect, even if i have the router with me, in the lower area of the wifi it shows the message "saved" i try to forget the network and reset the password but i still can't connect, I have to restart the phone to be able to connect normally, but after a while the problem returns.
I'm using a custom rom called AOSIP with android 10, I have already used pixel experience, Crdroid, Evolution x, Havoc os and absolutely, all have the same problem. I want to make it clear that I have already used android 10 on my redmi note 7 (pixel experience) and I didn't have any problems, the problem started after the February updates this year.
I don't think it's a hardware problem because going back to miui or a custom rom with android 9 solves the problem.
I would like to know if you already know about this subject or if you are already working on it or if there is a solution.
thanks

I think you might be onto something. In my case, the problem has been with Wifi Tethering. The phone is basically unusable as a hotspot, cutting out frequently and randomly and I think this has something to do with your wifi problem, maybe a driver issue? Like yourself, I've tried several aosp roms, all have the same problem.
Do you recall the last Pixel Experience release without this wifi issue? I am considering rolling back...

Do you recall the last Pixel Experience release without this wifi issue? I am considering rolling back...

Good morning, I've already tried the most recent version of pixel experience, in fact the AOSIP rom is from May 17, 2020, practically yesterday.
Obviously it's a driver problem, but I don't understand why all custom roms have the same problem and I don't know how to solve it either (in android 10)

I think you might be onto something. In my case, the problem has been with Wifi Tethering.

Could you tell me what rom are you currently using?
Could you also tell me the release date of the rom?

Currently on StagOS May 11 build. I settled on that after trying Pixel Ex, Evolution, etc as it was the one with the least hotspot issues; which isn't saying much as tethered devices would randomly lose internet connection while the phone clearly had internet and you could browse on any browser on the phone.
Since you say the issue occurred for you after the February updates, maybe you could point me to the last stable build you used so I can roll back.

I recommend all the versions that are from February, I would like to use pixel experience from that date but the page only has recent versions.
if you want a specific version use Crdroid 20200209
crdroid if you keep your old versions in the cloud so I recommend it, but I can not guarantee that it is totally stable. Pixel experience if stable but they don't have the versions of those dates.

I would like you to install the most recent version of pixel experience and when configuring the wifi, you will move away from the router until the signal goes away and try to connect again, just to check if it is really my phone or not.
Obviously making a backup before and also doing all this is optional. If you don't want to do it there is no problem thanks.

I already tried StagOs, I still have the same problem with the wifi, I also tried the hotspot and as you say if there is a data problem and in general it is unstable.
I downloaded the latest version of pixel experience and as expected the wifi was still failing, but the hotspot was working correctly so you can install it without any problem.

Okay sorry for the delay, been busy experimenting. Your recommendation of the Feb 09 crdroid build was spot on, flashed it, wifi and hotspot works like a dream, no issues at all.
After confirming that I decided to take a backup and try a recent AOSP build. I had already tried the Pixel Ex May 11 build and had the same issues so I downloaded the most recent build of Evolution X (May 17) and flashed.
So far, (Fingers crossed) I have not been able to replicate your WiFi issues or my tethering issues. WiFi did not disconnect even at a distance of over 50ft from the router. Keep in mind that these connection issues occur randomly but there's been nothing so far.
I will continue to use this build and test for the rest of the day. If I experience any dropouts I will restore to the stable crdroid build. Maybe you should try the newest evolution or go back to the stable crdroid to test if the issues are software related or specific to your device.
At this point I've been testing the latest build of Evolution (May 17) for about half a day, and zero problems so far, very stable.
I recommend you try it, may fix your wifi issues.

I am very happy that I found a solution to your problem, then I made some tests by creating an access point with my sister's phone ( xiaomi mi a1 ) and I performed the distance test and my phone connected normally. After several tests I am reaching a preliminary conclusion that there is an incompatibility with my router, I would need more tests with another router to conclude that my router is practically obsolete. That would also explain why I haven't found another thread with this same problem
good luck, tell me if you have finally solved your problem
