Thanks a lot for your help. I was afraid i hadn't planned it enough and spent the whole weekend coughing up dust for no reason. The shared uplink is now 1GB on this switch. and it's only shared between 3 users so i doubt we'll saturate it in the near future.
Thanks a lot for your help tompsonn. Much appreciated.

Good luck finding a switch these days without auto-MIDX (even the cheap ones!).
Glad it's sorted smile.gif For the record, a Cisco 300 series switch might be plausible in the future if you need a thicker uplink. You can use LACP to trunk switches together (either normal ethernet ports or via the two ComboC ports on the switch).

Because 100mb only uses a subset of the Cat5e copper wires, whereas gigabit utilizes them all, it sounds like termination for one or more of the gigabit wires was bad, hence the switch only detecting a 100mb link.

Ya also with 1000BASE it only negotiates the connection over 2 pairs, so if they are good you can get a 1000BASE light. Depending on the hardware on each end you can endup with a working slower link or a "fast" non-working link. That is a real pain to diagnose without a cable tester, and that is what happens when one side is T568A and the other is T568B. redface.gif

Glad you got it sorted. One thing to watch out for when using Cat 5e is that some cables can be labeled "2-wire". I got one of these with the free router from my ISP and was wondering why it didn't do GigE on a GigE switch...

Is that just cable that's wired for RJ45 but it isn't really twisted-pair? I got some cheap 'cat5e' on ebay but when i cut it open the wires weren't twisted.

Monoprice or Cables2Go for cabling if you are ordering online.
Unless you have a local distributor that has competitive pricing.
