Public bug reported: Hi,
I am am experiencing slow wifi for a Linksys WMP54GS v1.0 wireless PCI card with Ubuntu Server 20.04 installed, e.g. apt-get has taken 18 minutes 41 seconds to fetch 459Kb. Following the advice from https://ubuntuforums.org/showthread.php?t=2214110, I have installed the firmware-b43-installer package. The card is recognised and is sometimes allocated an IP. When it is connected, it is very slow. Using the wireless-info tool the logs for the wireless system configuration is given below. As shown in the logs the b43-pci-bridge driver is outputting an error message concerning the swiotlb is full. Has anybody managed to get the Linksys WMP54GS v1.0 card working on Ubuntu Server 20.04 using the b43 firmware supplied in package firmware-b43-installer? Since the log was produced I have also tired setting the REG_DOMAIN in /etc/default/crda but still does not work. ########## wireless info START ########## Report from: 04 May 2020 09:24 UTC +0000 Booted last: 04 May 2020 00:00 UTC +0000 Script from: 22 Oct 2018 03:34 UTC +0000 ##### release ########################### Distributor ID: Ubuntu Description: Ubuntu 20.04 LTS Release: 20.04 Codename: focal ##### kernel ############################ Linux 5.4.0-28-generic #32-Ubuntu SMP Wed Apr 22 17:40:10 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux Parameters: ro, maybe-ubiquity ##### desktop ########################### sed: can't read /root/.dmrc: No such file or directory Could not be determined. ##### lspci ############################# 04:04.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd.
