I am developing and managing a real time seismic data network.

I have 2 3com dual speed office connect hubs connected back to back with 3 computers connected to hub1 and 8 computers, 1 router and one multiplexor connected to hub2. Most computers are using 100Mbit ethernet cards but the multiplexor and at least 1 computer are running at 10Mbit.

Problem:
1. The network utilization lights are turning off on a regular basis on hub1. This can be rectified with a simple power cycle of hub1.

2. Sometimes I am unable to communicate back to the 10 mBit multiplexor. This results in data loss and can be rectified by a power cycle of hub2.

3. At one time I had a computer7 with a 10mbit ethernet card connected to hub1 but computer7, which was only a data display machine would lose contact with the network (ie data was no longer flowing into computer7, the screen display stopped). This problem could be resolved by a simple power cycle of hub1.

comment maybe these hubs are not suitable for this level of network traffic??

Any comments??
