https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=291404 Bug ID: 291404 Summary: rtw880 RTL8821CE random disconnects and other errors ("error 95 during state transition", etc) Product: Base System Version: 15.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: wireless Assignee: wireless@FreeBSD.org Reporter: jetpackjackson@katzenmue.de Created attachment 265848 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=265848&action=edit full dmesg log Hi, I did a fresh install of 15.0-RELEASE on my laptop, and found that the wifi suddenly no longer worked when it used to on 14.3-p5. 1. The connection (which is valid and accessible) will sometimes connect and allow me to have internet, but then will randomly stop without anything in dmesg. 2. The driver spits out a bunch of errors, but I have also seen them during the times that the wifi has randomly worked. (see logs) 3. Occasionally, I was able to trigger a kernel crash by running 'service netif restart' but it's not consistent unfortunately/I can't consistently cause it to happen. 4. I have searched the existing rtw bugs but mine behaves differently, especially now that it's intermittently behaving whereas it was initially just not working. I have attached a full dmesg log ("chonky-dmesg"), as well as a smaller log containing outputs from the log along with ifconfig output and ping output taken at the same time ("logs.txt"), and a log containing pciconf output ("pciconf.txt"). Please let me know if more logs are needed or what other commands I can run to help debug this issue. Thank you in advance. -- You are receiving this mail because: You are the assignee for the bug.
