Cat5e is good to 100 meters (300 feet) on a single line run, so long as
there are no breaks. Coupling two short lines together to make a long
one creates all kinds of issues with timing changes, signal attenuation
or complete loss of signal. Two solutions are to add something to
re-time and regenerate the signal at the break (hub, switch, etc), or
pull a fresh unified run of cable. This is most likely not an issue with
a NIC, but it's a good idea to keep that spare one around for down the
road. Best of luck.

Subject: [PCBUILD] Network lag on Cat 5e

Hi again

Another question on another topic.

For the network experts out their. I have a wired leg off a wireless 
router running Cat 5e cable. I seem to have a lag on a section which is 
100 foot long but it's in two 50 foot sections. I'm wondering as to the 
possible chance the lag is caused by the 100 foot length as being to 
long and thus a signal loss? I don't know for sure how long is too long 
on Cat 5e. Also if it is the length, would putting a switch in the 
middle help or make things worse. The lag might also be caused by the 
computer using the on-board LAN (on the motherboard). I do have a 3-com 
(pci) card I can install if using the on-board LAN might be the problem.

Thanks
