Hi thereI was suggesting to run a sort of stress test. iperf is a network performance testing utility which is well known and widely available.
You might consider running some varied tests through the updated driven to ensure yourself that its now behaving more stable. On the other hand you may find that under high load (or something) that there are still problems - which you could then feed back to the driver author.
There are many useful iperf tutorials online, i cant recommend one specifically.

Hi, I must admit, I don't know how to do some long iperf (internet performance??) tests... what exactly do you mean?

Your emailhas garbled which driver is in use, could you please clarify andalso which kernel version are you using? Some steps i suggest are...- see if traffic is leaving your machine (mirror ports, hubs or across over to another machine. then use tcpdump or wireshark) - try unloading and loading the driver, does it work again?- check what options are available for the driver, and play withany you might have - update your kernel some more exotic things to check... - check that iptables isnt being triggered by something?- it could be an irq conflict, especially if the card (or driver) doesnt play nicely with shared irqs. you may be able to clear theshare by disabling an unused serial or parallel port- following from the above, you could change to polled rather than irq and see what happens. polling uses lots more cpu (ok thats anover simplification, it is better in some circumstances) - maybe your dns lease is expiring?

Another issue are the function keys. On my old Thinkpad, the tpb package worked very well, however, that package isn't available onamd64. What other possibility is there to get the function keys towork?
