Beryl Wifi Crash

Technical Support for Routers
1

Hi All,

I just started using the new Beryl MT1300 router.
The setup is as follows:
Router to WAN.
PC to LAN and to Wifi.
Wireguard to remote server.
Now every minute my Wifi times out for 4 pings and reports this Kernel log:

Anyone an idea on how to fix this?

As I have replied you via email, the message is warning.

If it does not affect your usage it should be fine. But I bring it to the attention of developers and they will have a check.

Hi Alzhao,

Thank you for your quick response.
Maybe I was not complete with my question, but this problem does impact operations as my wifi connections stops working every couple of minutes while this message occurs at the same moment.
If you need more information, please let me know!

I filed a bug internally and let wait for firmware upgrade.

Any Update on this?

I have a brand new Beryl and this bug keeps me from using it completely, since the WiFi goes offline every few minutes and I have to restart the whole router manually.

Can you please change one power adapter?

I have one power adapter (not the one comes with the router) which cause this problem on 5G wifi.

I have verified that it only happen to that power adapter and not yet know the root problem.
