Connection & network problems

[Martins]

Using Macs 10.2.8 with ADSL router connected to 2 hubs/switches. One computer (iMac G4) acts as host to 2 other FM v6 users. All cables ethernet and switches/hubs 100Mb. Throughout the day, email/internet access will drop out and in order to restore connection, often need to reset modem and/or router which causes hosting problems which can usually only be fixed by restarting everything!

Also have other connection problems (not seemingly connected to internet probs) and client cannot find Host, even though icon available over network.
