I am having a similar issue with my Thinkpad L15 Gen2 (Intel), running Ubuntu 21.04 with Kernel 5.11.0-25-generic: After a suspend/resume cycle, the LAN interface only receives at very low speed (less than 1 MBit/sec reported by iperf). So far only rebooting brought back the full speed (approx. 950 MBits/sec.).
It seems that using the MEI fix from #77 also fixes the problem in this scenario - after applying the fix the network speed was back to normal immediately, and I tried several suspend/resume cycles with no decrease in network speed anymore. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1927925 Title: Massive network problems with I219-V on Thinkpad T14 Gen2 (e1000e) To manage notifications about this bug go to: https://bugs.launchpad.net/oem-priority/+bug/1927925/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
