I would like to know what results everyone get if they look at the
ethernet traffic on effected and non-effected radios. Log in to
simpeMonitor and pull up a client. Go to the 'Statistics' tab and click
on the 'Extended View' for Ethernet. Try this befor the radios lockup. 
On the Transmitted side:
You should see zero collisions of any kind on the transmited side unless
the radio is plugged in to a hub with two or more other devices
attached. If you see any, make sure all devices connected are set to
10BaseT/Half Duplex. I have only seen this happen on radios connected
directly to the clients computer. CRC Errors should also be zero. If it
is excessive compared to 'Total Packets' then the cableing is probably
bad. If you see any 'Pause Frames' and the clients is not running a 386
computer, then you can guess that the TCP/IP stack in the OS is Fragged
or the buffer in the NIC is going bad. 'Single Defer Packets' should
also be low or zero and are caused by congestion on the ethernet side.
Add a router to help solve this problem.
On the Received side:
CRC Errors usually indicate that the NIC is faulty. Unknown OP Codes
come from trying to use VLAN tagging or other Layer 1 extensions that
are not supported. Check the protocols attached to the LAN port on the
computer. Just about every other error indicated a bad NIC or damaged
cableing except for Oversized Packets. An oversized packet is generally
caused by a late collision which indicated that the ethernet cable is
too long (over 300') or the network diamater is to large (over 1500' to
the farthest client with no more than 2 repeaters IE Hub, switch,
etc...).
If you see anything other than zeros below received broadcast packets or
transmitted unicast packets let me know. I am trying to study ethernet
errors for the smartBridges MIB Hadbook.
