Network causing shutdown

Belkin wireless network, 2 systems 98SE on both. The networks been running
fine for months then all of a sudden it's fell over.

There was a slight intermittent problem that occurred sometimes when the 2nd
system was turned on, the main system would freeze. Now it's fell over
altogether.

Belkin support said reinstall the adaptors. Did so, no good. Every time the
2nd system is turned on the main system freezes. If the main system is
rebooted it freezes again within a couple of minutes. Any help appreciated.

Thanks. Ron
