Using broadcom-wl ?

mikerog25 commented 4 years ago

Hi, yes it is Broadcom but I have both radios disabled, using other WiFi solutions on network. I rebooted a couple of times without luck, but then detached it from wan connection to try a downgrade. When booting up offline to do the downgrade to 18.07, graphs were working. How weird. When I get a chance it try it again connected . I guess I'm happy for issue to close as its not blocking me as I'm using another device for now.

Same bug vith empty Graphs. If I disable Wan interface (3G USB modem) - the graphs start working.
