Q: Okay, this makes no sense to me whatsoever . can someone explain to me what the problem is!? I have an HP laptop with the Realtek 8139 chipset. I was using a 50ft CAT5e cable when I wanted the best transfers between my computers instead of wireless to get. Then one day stopped working, so I thought it was the port or cable. Ive tried a 6 m cable and it works fine, so I decided it was the cable. I tried another 50ft cat5e and it doesnt work and then I tried a 50ft CAT6 and doesnt work either. can someone explain to me why this isnt working? There was a driver update that affected this, there is some setting I can change? I know this sound like stupid questions, but Im baffled .
Thanks in advance,
dan: confusion:

yeah, i tested them with my desktop system just now and it works fine. The only reason why i am confused is the network card shouldnt see the difference between a 6 foot cable and a 50ft cable… ya know? its very very bizarre….
If its bad it will "see" a difference.

Re:Can you test the 50ft cables between two other systems?
I personally wouldn't expect much from a realtek 8139 card.

BUT 3 DIFFERENT 50ft cables? Doesnt that seem odd? and i know that 2 of them worked fine before! any other ideas?

If you've swapped 3 cables and those cables have been verified good (either by certifying them or using in a different installation) then it must be the network card.
My angle is that most all network problems are from the physical layer (cable). Make sure they are indeed cat5 cables.

nope, all store bought.
something is really not right then if they are store bought cables.
BUT – it does happen that pre-made cables are bad. Or, the NIC could be bad. Its rare, but it does happen.
Re:nope, all store bought.
Re:Were those cables hand-made (you or whoever) or purchased, commercial-grade stuff?
If you hand-made them, did you follow the EIA/TIA spec?
If not, that's likely to be your problem.
FWIW
