WiFi is still not working - very disappointing. No updates?

Fydetab Duo
1

I’ve had my Fydetab Duo for a couple of months now, but am still unable to use it because it will not connect to my WiFi router.

This is the same router that has successfully connected with literally hundreds of devices of all shapes, sizes, quality and price. I fail to understand why the Fydetab Duo cannot connect, simply displaying “bad password” which is untrue.

Basically I’d dumped the device in a corner for a month, and was hoping that when I switched it on again yesterday that I’d be able to make it work, but no luck, even after changing some router parameters. I connected it to my phone and checked for a firmware update, and disappointingly, there was nothing.

Is the device still supported and when can expect some proper support?

Sorry about the bad experience. Earlier versions of FydeOS for Fydetab Duo had issues connecting to WPA3 Wi-Fi networks, and this has been fixed in the latest v21-SP1.

If possible, please try USB tethering (network sharing) from an Android phone, then update the system to the newest version. If that’s not possible, you can follow the instructions on the Fydetab Duo Wiki to flash the latest version manually:

And you can download the newest FydeOS system image here:

My Fydetab Duo updated to FydeOS 22 and I am having the same issue with “bad password” when trying to connect to my home wifi. This was not an issue before the update.

Can you share more information why this happens and how this can be fixed?

Could you send feedback in the system? In v22, we upgraded the kernel. During our testing, we did not encounter any Wi-Fi connection issues. However, since there are significant differences compared to previous versions, there may still be some corner cases that were not fully covered.

I was frustrated and installed Arch instead, I do miss having access to Android applications though.

Not sure I will install FydeOS again just to send a bug report. I might.

I was able to connect to the WiFi hotspot on my phone when having issues connecting to my router.

All I can provide right now is that I have an older router (10 years old??)

Before installing Arch, I found a downloadable FydeOS v21 and installed that and did confirm WiFi was working just fine again.

Then, it automatically updated to v22 and I could no longer connect to my router with error “bad password”

Here’s a Reddit post where multiple people are reporting the same thing.

Buy a new router I think it would get resolved.

It is possible that the issue is caused by the router being too old. In this update, we upgraded the Fydetab kernel from the Rockchip vendor kernel 6.1 to the Google ChromiumOS kernel 6.12, which may lead to compatibility issues with older routers.

The new kernel brings improved system stability and better graphics performance.

I bought the FydeTab Duo several months ago. Out of the box, everything worked! The touch screen, wifi, the keyboard, the pen, touchpad, Linux and Android. I was very impressed.

Trouble began after immediately updating to the latest version. Wifi never connects, falsely reporting “Bad password”. I flashed back to v21.0. This worked! But v21-SP1 failed. So did the most recent, v23.0-SP1. Note that I had to guess what file names to download because a link to the older images was not obvious. Setup does not let you skip connecting to wifi, though this would be helpful.

The router uses WPA2-PSK (AES), which works with almost every device in my experience. It is a Netgear Nighthawk R7000, firmware v1.0.12.216_10.2.122.

Because automatic updates are on by default, wifi stopped working again after rebooting (because it installed v23). It booted this even though I disabled automatic updates after the update finished downloading.

The automatic update begins immediately after boot. You seemingly cannot cancel it. Automatic updates may not be turned off while an update is downloading. But you may disconnect the wifi, reboot the system, then cancel automatic updates, then connect to wifi again. Any Linux system setup will need to be re-initialized. Also, returning from sleep will still create the same bug. You will have to reboot to restore the network.

The issue is still the same. This router is too old, and the newer Realtek kernel no longer supports it. It’s a 13-year-old model—it’s time to replace it. Routers that have reached end of support can pose security risks.

By the way, I work in cybersecurity. AI is lowering the barrier to some types of cyberattacks, making it easier for people with limited technical skills to cause harm. One basic step everyone can take to protect their home network is to use a router that still receives security updates, keep its firmware up to date, and configure it securely.

We recently found that some changes made to fix WPA3 connectivity issues may have introduced compatibility problems with older routers. We’re purchasing a Netgear Nighthawk R7000—the same model as yours—to see if we can reproduce and fix the issue.

This issue was caused by the WPA3 support we introduced in v21-SP1, that would lead to the incompatibility with some old routers(especially the ones with Broadcom SoC).

You may try the following steps to fix this issue temporary:

press ctrl-alt-t to open crosh, then execute the following commands

crosh> shell
chronos@fydetab_duo-fydeos / $ sudo mount -o remount,rw /
chronos@fydetab_duo-fydeos / $ sudo sed -i 's/^sae_pwe=2/sae_pwe=0/' /usr/lib64/shill/shims/wpa_supplicant.conf 
chronos@fydetab_duo-fydeos / $ sudo restart wpasupplicant
wpasupplicant start/running, process 7291
chronos@fydetab_duo-fydeos / $

Reconnect to the failed WiFi AP, it should works now.

Wow, it does indeed work. You’re super responsive. Thanks for investigating!

Hacker is also right of course, though I won’t always be able to choose what wifi I’m connecting to.

Note: ctrl-alt-t opened crosh
