Various channels on 2.4GHz band. Distance between hub and computer
made no difference.
I tried the two broadcom-sta drivers, but they failed to compile,
versions 6.30.223.248-3, from the ubuntu repository.
I was having what I thought might have been radio contention, so I changed
the radio channel from the default of 8 up to 12.
Various other Windows and Android and Xubuntu devices reconnected with no
trouble but this newish laptop stubbornly refused to reconnect.
iwlist wlan0 list didn't include my hub and 'connect to hidden WiFi network'
didn't succeed.
I tried reinstalling drivers and such without success.
Then I changed the radio channel down to 9 and voila, things were on-line
again.
Also, this driver doesn't seem able to handle the 5GHz channels either, even
though I get:
iwlist wlan0 freq
wlan0 32 channels in total; available frequencies :
Channel 01 : 2.412 GHz
Channel 02 : 2.417 GHz
