    Ok, I have a big problem. I have ethernet wiring in the house, but I want to upgrade to gigabit, my problem is that I have Cat5, not 5e, 6 or 6e. If I hook up a gigabit switch to just cat5 what should I expect?

    Would it just default back to 100Mbit/sec or would I see somewhat of an increase. I do have gigabit lan cards on my machines, so the wiring is the only thing holding me back from gigabit, minus the switch.

    If I do need to rewire it what could I expect to pay? I have about 200-300ft of ethernet cable that needs to be replaced, and all the cabling is behind drywall.

    The NICs & Switch would try to run at 1000Mbps but since the cables are not rated to that level you would probably have excessive cross-talk on the wires causing performance degradation. Exactly how bad the problem would be is hard to say. (Or rather hard for me to say.)

    It's possible your cat5 cable could actually pass the tests to meet the cat5e specs in which case you'd probably see no problems, but on the other hand it might not fair that well and actually perform worse than simply running at 100Mbps. I'd guess not, but that's just a guess.

    Regarding the cost of replacement I have no idea. Call some local cabling companies and get a few estimates.

    :p :lies: ;)

    Good luck.
