Router help needed

[Sagittaria]

I have a home phone line network set up, 3 computers connected to a
Linksys HPRO200 router. All computers are running windows xp and
using linksys hpn200 cards. The router is connected to a cable
modem and to computer 1. Computers 2 and 3 are in different rooms,
plugged into phone jacks.

I am having 2 problems.

1. Intermittently the router drops the connection. It restarts
almost immediately, but if I'm downloading something it is thrown
off. This happens on all 3 machines.

2. My bandwidth speed on computer 2 is nowhere near what I should be
getting. My cable connection is 1000 down/200 up and computer 1
tests at that speed, but computer 2 tests at around 350/150. I
haven't tested computer 3.

Before I had the router, computer 1 was plugged into the cable modem
and shared the internet connection to the other 2 machines. We never
had any dropped connections at that point (problem #1). I'm not sure
if I ever tested the speed with that setup, so problem #2 may or may
not have existed.

What more can I do to test and/or solve these problems? Any help
would be greatly appreciated!

This is most likely to be caused by bad cabling. If you didn't use at
least Cat5 cables for your phone cabling, the shielding will be
insufficient and thus you are experiencing packet loss.
While the comuter with the shared connection was able to compensate
that using the mechanisms of TCP your router is unable to employ TCP's
error corrections.
