Hello,
recently a Win 7 user had several connection problems. The PC was connected to an 2940.
I checked the Switch and got Ping timeouts at different time intervals (from every 2nd packet untill every 20th packet).
The problem is recoverable and happens on different PC´s/Cabels with dif. OS (Win7, WinXP, Linux Mint).
I also used different ios versions:
c2940-i6k2l2q4-mz.121-22.EA12
c2940-i6k2l2q4-mz.121-22.EA13
c2940-i6k2l2q4-mz.121-22.EA14
and tried different settings like
duplex half/full
mdix
speed 10/100
and apparently speed 10 was the only thing that worked out.
CPU utilization looks also fine...
Any clue?
Greets,
