To All:
      I am using a pair of 3C905B-TX NICS.  I pulled the logs.  Here is what 
I have:

      WAN interface
      Status up
      MAC address
      IP address 208.17.66.204
      Subnet mask 255.255.255.224
      Gateway 208.17.66.193
      Media 100baseTX <full-duplex>
      In/out packets 471805/453678 (248.37 MB/105.20 MB)
      In/out errors 0/0
      Collisions 0

      LAN interface
      Status up
      MAC address
      IP address 192.168.14.10
      Subnet mask 255.255.255.0
      Media 100baseTX <full-duplex>
      In/out packets 1114677/1051494 (189.18 MB/333.25 MB)
      In/out errors 0/0
      Collisions 0



2 days, 00:15   I have reboot once a month to clear the modem.  I have been 
tweaking my configuration to the limit.  I have it running perfectly.

I am using a c3 giga pro motherboard with 256 mb of ram.  I have a total of 
4 interfaces.  The 2 3com adapters, the on-board adapter, athern wireless 
adapter.  I am bridging the wireless to the LAN side.  I would look at the 
link speed of the port that the 3 Com adapter is connected in.  I recently 
ran into a issue where one of the 3Com adapters was negotiating 100 half but 
reporting 100 full.  I found the issue with Ethereal.  I saw error in the 
trace.  I set the post speed of the WAN to 100 full and my DSL modem has to 
be set to 10 half. This was step up with a managed switch with 3 vlans.

VLAN1 - modem connection
VLAN2 - LAN Connection
VLAN3 - OPT1
OPT2 - bridged to the LAN via the M0n0Wall

Once done it was great.  It was no issues.  I have simplified my network 
with a Netgear router.  Just for a 4 port switch.  I am only using 1 port 
and everything else is wireless.  I be glad to give anyone on the forum 
anything that I can.
