Public bug reported: In brief, I upgraded Kubuntu 18.04 to 20.04 Beta.
STEPS TO REPRODUCE 1. Connecting to as yet "random"(?) websites (duckduckgo, startpage, and OMGUbuntu for example) can result in extenuated wait times for page loading. 2. Attempting to updatwapt leads to failures to fetch. 3. Connecting to Speedtest.net resulted in 300 mbps upload and download whereas onnecting to https://www.speakeasy.net/speedtest/ resulted in a Connection Has Timed Out Error.

(This is getting quickly above my pay grade.) I used Grub Customizer to boot with kernel 4.18.5-041805-generic and network connectivity/throughput is now functioning as it should. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871408 Title: Upgrading 18.04 to 20.04 causes Network/WIFI Throughput Slowdowns To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1871408/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
