I would like to update a location that is using an old 10MHz hub, but I am very perplexed.
When I replace the hub with a switch I encounter some connectivity problems. Some computers have faster connections as I would expect, but some computers can't connect at all.
Tried a Gigabit switch then a 10/100 switch, different brands, one new and one used. The used switch I took from a working environment where I knew all of its ports were in use and working.
The network cabling at this location is very old and is in a rough use environment. Some of it is Cat 3.
If I put the hub back into place then all computers connect ok.
Dell server running 2003, 8 client computers running Win 7 or XP, cable modem, Cisco RV220W router.
What could be going on here?
