Mt7601u fails with new kernel 5.14.21-150400.24.84.1

English Network/Internet

Since installing the new kernel I’ve noticed in the message log that what previously was working is now broken. In particular, the log shows a continuous stream of attempts to connect to the wifi dongle ID 148f:7601 Ralink Technology, Corp. with the following excerpt from the log.

What else can I provide to help solve this?

Thanks.

Does it work if you boot the previous kernel?

3

It does connect and work with the previous kernel. Thanks.

4

Then it is regression and you need to open bug report on https://bugzilla.opensuse.org/ (same user/password as here).

5

Thank you. I’ll try that.

This kernel version has been retracted, so the best thing to do is the delete it.

If you need instructions on how to delete this kernel version, please see Installing multiple kernel versions | Reference | openSUSE Leap 15.5

I had to scroll to the bottom of the versions list to find the retracted kernel to remove.
