Disable wifi (nmcli radio wifi off) and problem leaves. I threw in the towel and did a fresh install of F32 to no avail. A little research reveals similar/same problem in mac80211 beginning around kernel 5.6.9 IIRC. In any case wifi is to important to me so I will need to revert to CentOS until this is fixed or if it is a hardware issue the kernel can deal with it (report and move on). I am suspicious about a hardware problem since sometimes I can run connected through wifi for hours, other times the problem appears quickly. I'll keep it up to date and if/when the issue is resolved I'll be back. Let me know if I can provide any info or tests. -- Roger Wells, P.E. leidos 221 Third St Newport, RI 02840 401-847-4210 (voice) 401-849-1585 (fax) roger.k.wells@xxxxxxxxxx _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
