Hi all.
I have this Belkin rt73usb card – it’s connected to this SUPER OLD Thinkpad 600E machine and it’s associated always with only one router – static IP setup – basically laptop is stationary / not moved. I had little problems with connecting it to the network at boot time but thanks to Boohbah from #Archlinux channel and a bit of research I got it to connect and to turn off power management and to keep the rate as “fixed” 54M – worked well BUT… I had a problem with it – the connection stayed up – I could browse the internet from the thinkpad / I could access the sshfs share on my server (from Thinkpad 600E) and so on but after a while sshd port – 50505 in my case – was switching from open into filtered and I could not connect to it anymore.
Example – rebooted Thinkpad 600E – i can connect – Thinkpad was left alone for lets say sometimes 10 minutes – sometimes an hour – connection was active but I could not ssh to the machine anymore.
After a bit of investigating I have found this line in the dmesg (after the connection dropped)
ieee80211 xyz0: abc0: No probe response from AP xx:yy:zz:aa:bb:cc after 500ms, disconnecting
and I had googled it but could not find solution so I have asked for help on the Arch Linux forum and Strike0 has sorted me out in no time. Thanks Dude!
I am reposting the info here just in case forum post goes missing in the future. To solve this issue I had to do this:
As root add:
options rt73usb nohwcrypt=1
to the file:
/etc/modprobe.d/modprobe.conf
and save it. Then re-create kernel image with
mkinitcpio -p linux
and reboot.
Hope someone will find it useful in the future.
Regards.
Andrzej
