Kindle 8th Generation Wifi stopped working after upgrade

Monstrabilis · 05-05-2022, 04:25 PM

I bought a used 8th generation Kindle, successfully registered it, and set it up. All was good. Then I got an update to 5.13.7 (I think, this was a while back). After the update, Kindle would no longer connect to wifi. It just comes back with "Wi-Fi Error" after 10's of seconds. I tried different networks, different routers, wide open network without password; never connects. I tried reset to factory; still won't connect.

I contacted Amazon and told them wifi stopped working after the update and they suggested I return to who I bought it from or trade it in for a new one. Not very helpful.

Each time a new updates comes out, I download it and send it to the Kindle via usb hoping it resolves the problem, but no luck. I'm now up to 5.14.2. I recently noticed the jailbreak instructions here and successfully completed it. I installed Kual and kterm, so I can now poke around in a console.

Does anyone have any idea what I should look for to resolve this? The screen where you select the wifi network lists the networks and shows signal strength, so it doesn't seem like a hardware problem. Thanks in advance for any assistance.

I found a suggestion on another post on a different Kindle. Delete everything in /var/local, restart, and the Kindle will rebuid it. Didn't fix the problem. Anyone have any ideas?

I assume you have JB.
Then connect to ssh and post the output of the command "showlog -f" here while Kindle tries to connect to Wi-Fi.

Ssh without wifi? I'll see if I can get it another way.

Yes, the OG ssh is done via cable in USBNetwork package by NiLuJe. This is the mode when you lose access to mount Kindle as a disk when connecting cable, but get ssh instead. USBMS (mass storage) it was called in the KUAL menu of that package, IIRC.

Got it. Here it is ...

OK, looking briefly at the log, I can see a lot failed scanning and connecting attempts, but also some successful connection to a network with SSID C***t.
The main executive (don’t know to properly call it) is the Wi-Fi daemon called wifid in short or com.lab126.wifid .

While I don’t have an expertise in this as deep as @katadelos, @NiLuJe do, for example, but in the meanwhile you can try changing wifi channels on your router. See if it helps

I have tried other channels, other routers, other networks in other locations. It still won't connect.
