Wifi generally works well, but there are times when it slows down considerably or completely disconnects. This happens randomly, and I don't have such problems in Windows 10. I'm wondering if there is something wrong with the r8169 driver? I read that it could be troublesome. The problem seems to fix itself after restarting, booting into Windows, restarting again, and then booting into Ubuntu. I'd like a more permanent fix, though.

I tried replacing r8169 with r8168 but I was not able to use r8168 because it said the module could not be verified and there was a missing required key.

The drivers you refer to have nothing to do with a wireless problem.

If you're having ethernet problems, you should replace the buggy r8169 driver with the r8168-dkms driver from the repositories, AND turn off secure boot in the BIOS.
