Question : PC with 3c905c-tx NIC returns 110ms ping, but rest on same hop <10ms.

Their are three computers in our 10.10.20.0 segment, the two intel pro 100 NIC return constant <10ms ping, but the 3com 3c905c-tx is steady with 110.  I intermittantly loose connectivity too. But I appears to be the T1 is unstable.
I'm using needTEXT and freeping to monitor connectivity.

Maybe I have a incorrect device setting on the 3c905c-tx.
Here is a list of the device settings.
802.1p Support                     Disabled
DoubleNego                          Enabled
Down Poll Rate                      8
Eng LAN Power Mgmt            On
Flow Control                         Enable
InitDelayCount                       0
LnkChk                                 Enable
Media Type                           100 MB, Full Duplex
PHYCompat                          Enable
RWU ARP                             Disable
RWU Magic Pkt                     Enable
RWU Ping                             Disable
Rx Checksum Offload             Enable
Software Cable Detect           Off
Stdby RWU Magic Pkt             Enable
Stdby RWU Pattern                Enable
Tx Checksum Offload             Enable

What is:
    RWU stand for? (Restart/WakeUp?)
    PHYCompat ?  What does it do.

Well anyway any ideas appreciated.

Unfortuatly BestBuy, CircuityCity, MicroCenter don't carry Intel pro 100 NIC and CompUSA's has them for delivery only.  Or I'd just go get one today.

500 pts is for urgency.

Answer : PC with 3c905c-tx NIC returns 110ms ping, but rest on same hop <10ms.

Try the following config :

802.1p Support                     Disabled
DoubleNego                          Disabled
Down Poll Rate                      8
Eng LAN Power Mgmt            Off
Flow Control                         Enable
InitDelayCount                       0
LnkChk                                 Enable
Media Type                           Auto
PHYCompat                          Disable
RWU ARP                             Disable
RWU Magic Pkt                     Disable
RWU Ping                             Disable
Rx Checksum Offload             Disable
Software Cable Detect           Off
Stdby RWU Magic Pkt             Disable
Stdby RWU Pattern                Disable
Tx Checksum Offload             Disable

This is a FailSafe configuration .
In the same time, update all drivers from 3COM .
If you are usind W2K or XP try PATHPING  <targetIP> to see some statistics.
From another point of view, check cable and conectivity. A ... question: if you change the connection point ( INTEL <-->3COM), the response is the same ?! If NO, you ave some collisons or other connectivity problem.
Try another test : FTP , the same file from the same server . If the result is the same time, don't lose time to fix a PING response. :-)
