Some thoughts for Fire HDX 7" & 8.9" WiFi Issues

Some users on this thread (and also on the LOS16 thread) have reported WiFi connection problems which seem to be dependant on the make of router they use. I have tried to put all the information that I used to improve matters a little in one place.

Signal from a WiFi router is often a combined 2.4Ghz and 5Ghz, both with the same SSID and password.

Typically 2.4Ghz has a better range than 5Ghz and is less afected by building structure. 5Ghz gives better performance but only at close range. The device automatically switches between the two frequencies seamlessly monitoring the quality of received signal.

The HDX tablets have a Qualcomm Snapdragon processor which seem to have some issues in dealing with multiple band WiFi and tend to suffer from dropouts and connection issues.

Editing the WCNSS_qcom_cfg.ini file to change the way the tablet deals with the received WiFi signal can make an improvement to this.

Unhide developer options and enable root for tablet.

Use a root file explorer.

From root, navigate to :-

/system/vendor/firmware/wlan/prima

Use a text editor to edit:- WCNSS_qcom_cfg.ini

Change BandCapability=0 to BandCapability=1

0 = auto, 1 = 2.4ghz only, 2 = 5ghz only.

Changing to 1 will set a preference to connect to 2.4Ghz even if 5Ghz is close enough to be viable. 5Ghz has not been disabled but your tablet will not switch to it automatically. This should improve the reliability of the WiFi service greatly.

To increase channel width, find the entry :-

#ChannelBonding

And add this line underneath

gChannelBondingMode24Ghz=1

There is already one of those for 5Ghz, but adding the 2.4 Ghz channel bonding will allow the radio to use 40hz channel width on 2.4Ghz channels as opposed to the default 20hz (essentially doubling your link rate as long as your router supports channel bonding)

There is a greater possibility for wireless interference if you enable a channel width of 40MHz. In general 40MHz wide channels over 2.4GHz is not a good idea in areas with a high density of WiFi access points.

If there are only a few wireless networks to interfere with your own, this fix provides an easy way to improve network speed.

Save and reboot

Many thanks to countless other internet sources that allowed this information to be brought together.

I don't have /system/vendor/firmware, there's just /system/vendor/lib.

A file of that name is located at:

/data/misc/wifi/WCNSS_qcom_cfg.ini

/system/etc/wifi/WCNSS_qcom_cfg.ini

Both seem to have no effect, my router shows the tablet connected to 5ghz.

I'm on Apollo 14.1 2020-05-28
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Buzzpcsos:
Couldn't see 14.1 2020-05-28 as a Lineage build, so it may be why the position of the files is different. My own tablets are on lineage-14.1-20200705-UNOFFICIAL-apollo and lineage-14.1-20200705-UNOFFICIAL-thor. The WCNSS_qcom_cfg.ini was located at the location specified for these builds and that is also true for the LOS16 builds.

Editing WCNSS_qcom_cfg.ini seems to have different effects depending on the details of the individual setup but there are so many positive experiences documented that it seemed worthwhile to record what to do and the effect it would have.

Changing to BandCapability=1 will not disable a previously established 5Ghz connection. If a connection to the router has previously been established then "Forget" that connection and set up a new one.

If the router settings have been changed to split the combined WiFi signal into a 5Ghz SSID and a 2.4Ghz SSID

then the problem you are trying to fix by editing BandCapability in WCNSS_qcom_cfg.ini has already been fixed.

Hope that helps a little.

Good idea, but after deleting and re-connecting it still connects to 5GHz. I guess these are still not the right config files

It may be that editing WCNSS_qcom_cfg.ini has mixed success as there seem to be numerous instances of it in the Lineage install, it is possible that the location I have used is not the correct one and the improvements that I have seen have been a placebo effect. Maybe a future build might incorporate the BandCapability tweak directly into the ROM if an improvement is deemed to be tangible by some other users.

Certainly splitting 2.4Ghz and 5Ghz signals at the router fixes a lot of WiFi problems so that might be an easier fix short term.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
/system/vendor/firmware/wlan/prima is the correct location on the later builds. This is a symlink to /data/misc/wifi/WCNSS_qcom_cfg.ini.

In the next build I could remove the one erroneously included within system/etc/wifi/

I think I was wrong. I looked back and realised I wanted to remove the symlink to /data/misc/wifi/WCNSS_qcom_cfg.ini

wncss_service is then forced to use the one at /system/etc/wifi/WCNSS_qcom_cfg.ini which is the correct location.

Maybe it's just me... tried doing a clean install with the latest Thor build and flashed OpenGapps Pico after and Gapps doesn't seem to show up on first boot. I can't remember how this is fixed.

Well I'm coming from the previous build of 14.1.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
Ok, I tried clean install on a tablet with a previous version of los14 and gapps did not show up at all.

I wouldn't have picked this up before as problem as I don't use gapps.

I just looked at the open-gapps Recovery_tmp.log and it looks like /system partition is not been remounted as read/write for some reason - will look into it.

EDIT:

Problem solved: Do the following:

1. Reboot into TWRP

2. Go into settings

3. Uncheck the option "Unmount System before installing ZIP"

4. Press back

5. Go into mount

6. Select System partition for mount (for good measure)

7. Press back and flash gapps

8. Factory reset if desired

9. Reboot

10. Should be all good after that.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Bwangster12:
For what it's worth... I followed these directions immediately after clean installing and before rebooting and it didn't seem to work. After I rebooted into recovery again and followed it again, it worked. Perhaps needed a boot up.

Updated the previous version to the new one without any problems the "dirty" way (wipe system, than install rom and gapps in one). Many Thanks for the fresh ROM to ggow!!
[Kindle Fire HDX 7" & 8.9" Original Android Develop] cl-i:
Yes, this helps me because 5Ghz is not in range for the tablet anyway.

And when WIFI is lost (overnight for example, cause Router is powered off), it reconnects way more easy!

Thanks, Buzzpcsos

Just flashed this, now my Thor won't start, LineageOS boot animation runs forever. After flashing it said "Unable to wipe cache: Invalid argument."

TWRP can't wipe cache, can't mount cache, repair errors with "/sbin/e2fsck -fp /dev/block/mmcblk0p21 process ended with ERROR: 8 - Unable to repair Cache."

Any idea how to fix this?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
that's odd, I upgraded on thor from the previous release of cm-14.1.

which twrp version are you running?

which rom were you running previously?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
This could be because I picked the wrong branch for building the compat-wireless driver. I can do you another build to test privately?
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Cl4ncy:
TWRP is 3.5.0_9-1

Previous version was lineage-14.1-20200705-UNOFFICIAL-thor.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
That was also my upgrade path...

it sounds like your /cache partition has become corrupted is my best guess.

you could try formatting the /cache partition from TWRP with the following command:

make_ext4 /dev/block/platform/msm_sdcc.1/by-name/cache
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Cl4ncy:
Didn't work (make_ext4 not found), only with make_ext4fs:

make_ext4fs /dev/block/platform/msm_sdcc.1/by-name/cache

But that didn't fix the problem. 🤷‍♂️

The previous version that I flashed back did load now, but some apps crash, e.g. google AppStore. Will try to flash the latest ROM again...
[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
Ah, make_ext4fs is what I meant.

I am not sure, might have to put this one out to the wider community for an answer.

If I think of anything, will let you know.

Wiping cache in TWRP worked now, did take a while though.

When I remember right : OpenGapps and the ROM must be installed in one step, otherwise gapps don't do work. I switched to Bitgapps and are fine with this very small package.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Cl4ncy:
Funnily enough I had to use @ggow's problem solving mentioned above to get OpenGapps to work/show up. But now the latest build is up and running, freshly installed. :)
[Kindle Fire HDX 7" & 8.9" Original Android Develop] ggow:
I have been meaning to do this for some time - testing the experimental cm-14.1-testing branch of the compat-wireless wifi driver so doing some extensive testing of this vs the cm-14.1 branches. Long story short is that the cm-14.1 branch wins hands down. The testing branch won't be carried forward.

I found that the 5GHz band wasn't operable in either Smart Connect or isolated bands on my asus router (AX-88U). Per 15 minute intervals over a few hours there were so many disconnects it was unusable.

Switching to the cm-14.1 branch things were very different, even with Smart Connect mode enabled on the router the tablet was able to connect @ 300Mbps on 5GHz with good throughput and 144Mbps on the 2.4GHz band also in isolated.

New build will be out shortly containing the patches that @void555 provided me with. If we can get as many people testing with this as possible it would be great. I have been testing with it this afternoon and it seems to have an impact on switching between bands successfully and reconnecting out of sleep seems better too.

I'll push the new build shortly.

I came across UAD a while ago, definitely worth a look.

It is a program for removing unnecessary apps that can reduce battery life or make the device more vulnerable.

There is a recommended selection of apps that can be uninstalled (for user only) with a descriptor of what each one does when you click onto the name.

It is worth spending a little time selecting the apps to remove as some of the recommended ones may be useful to individual users.

After removing the apps I rebooted and cleared the dalvic cache, everything seems to be running fine.

I also de-bloated my phone about a year ago, it is now a little quicker and has a longer standby life.

Be careful, I used the windows version and detected, that deleted apps can not be restored Later. On the other hand you can gain more free memory, especially when you don’t use LTE and remove all the telephony stuff.
[Kindle Fire HDX 7" & 8.9" Original Android Develop] Buzzpcsos:
I used the Linux version (which requires the file extension .appimage to be added to the file) without any issues. The program can Uninstall/Disable and Restore/Enable system packages without any issues. Apps are not removed from the phone, only from the user profile so they can be restored by deploying a factory reset or through the UAD program. The FAQ gives you all you need to know although some parts are a little hard to understand.

If there is a choice it is much better to use the Linux version just because it plays so much better with Android. No need to set up Android Platform Tools Program Path or worry about finding drivers for the tablet. I have used ADB on windows and was very surprised at how much easier it was on Linux.
