Networking at 1% net utilization

Hi, i know little about networking so bare with me.

i have 3 computers(all winxp home sp2) around the house connected via a d-link dsl 504t router(new).

computer (b) and computer © can share files at 80%+ network utilization and connect to the internet at max (1.5Mbit adsl).

computer (a)(mine) shares files at 1% network utilization and has poor internet connectivity.

The router(d-link dsl 504t) uses DHCP? to assign IP's??

specs:
a64(3400+) on a K8ne delux
1.5G ddr
x800xt
2 x WD sata raptors

Fresh(today)install of WinXP + sp2 + nforce 5.10 drivers

Problem seem to come when we bought the router.(used to use a 8 port switch, with no problems)

I have tried different cables. Using different ports on the router, nothing seems to help.

My computer is the only one with an on-board network card.(dunno if that should matter??)

Thanks for reading.

I got it to work really well for about 10mins today, by pulling every ones cables out of the router except mine, resetting the router and putting the rest back in, i got full bandwidth both locally and on the WAN.

Then about 10mins later i noticed the "network cable is unplugged" warning pop up for about 1 second. then performance was crap again.

I wonder if my IP lease time has something to do with this????

Hi tdbdisco, welcome to SAF

d-link dsl 504t uses DHCP to assign IP's. If this is happening on the new (fresh) XP installed OS, you may update it at MS Windows Update.

As far as I know, d-link router has a lot of filtering options and settings...

At a first try, you can release and renew your IP when the problem starts...

<Start/Run>
ipconfig /release
ipconfig /renew

You may also try setting static IP addresses instead of dynamic ones, but I am not sure it will work on this issue.

sorry, had no effect

thanks for your help tho

upon further testing i have tried connecting just 2 computers to the router (mine + 1 more) then resetting and all is good so far. I think adding a third to the mix stuffs it up (always my comp).

not conclusive yet

Is your OS fully updated/patched ?

completely, even my winxp cd comes with sp2 and the first thing i did was load Mobo drivers then DL all updates(slowly)

all other computers are fully updated, fresh OS's(since we bought the router)
