Hubs not working

Putumayo · 03-28-2008, 09:18 AM

I'm the IT Director for a SMB of about 100 users/computers. A few days ago one of our switches went bad. We have 4 and we moved all the cables to various ports on the other 3. Whomever networked this building didn't set up enought Data Jacks so we have about five 4 port hubs around the office with no more that 2 cpu's and 1 printer attached. Strangely enough a few of them are not splitting the signal properly. Whichever cpu gets an IP first gets a steady signal and the other gets the 'ole "limited/no connectivity". The printers are not affected. I'm completely baffled. Does anyone have any ideas?

What's the exact make/model of the hubs? Are you sure the connections from the switch will allow you multiple IP addresses? Have you tried one of the hubs that is working correctly in the position of one that doesn't? I'd also move the failing hub to where the working hub was removed from and see if that works.

I'll be amazed if the hubs are actually blocking traffic or preventing DHCP requests from occuring.
