One of my clients has a Zyxel ADSL modem/router and, until today, had a Netgear wireless access point plugged into one of the LAN ports of the modem router which served 3 PCs. There is also another computer which is wired directly to the modem/router.
Due to the nature of their business they had a lot of interference on wireless network and have decided to go for a more stable wired connection. So they replaced the Netgear wireless access point with a 3com 5 port hub.
Now all PCs, except the one directly connected to the router/modem, say "Limited Or No Connectivity" for the wired NIC card.
When the PCs are swapped (one the three problem ones with the one directly connect to the modem/router) each of them work, indicating the problem is the hub...?
I have tested all of the cables and all are fine.
All of the lights flash on the hub and would appear NOT to be faulty.
I have ran all the usual network troubleshooting methods, is it likely to be a problem with the configuration of the router/modem and the hub or is it more likely the hub is faulty?
If anyone could shed any light on this I would be very grateful.
