First, if you haven't already, try switching the ethernet cable on the affected computer. (We recently had a similar issue with the cause being a bad RJ-45 plug on one end of the CAT5 line.
Or... have you tried updating the ethernet driver on the problem machine??
Next, on the affected computer, it may be an ethernet device issue. I'd try making sure it's still set to full duplex.. In Device Manager, click on the + sign next to the "Network Adapaters" listing, then RIGHT click on the specific ethernet device, choose 'Properties', then click on the "Advanced" tab. Depending on your setup, choose the "Link Speed & Duplex" listing and make sure it says "Auto Detect" or you might even try setting it manually to "100 Mbps\Full duplex".
Hope this helps.
I have 3 computers hooked up to a home network.
They are: 1) AMD 3200 2.2ghz 2gb RAM Win XP SP3
2) AMD 3800 2.4ghz 2gb RAM Win XP64
3) Intel Q6600 2.4ghz(x4) 4gb RAM Vista Home Premium SP1(I think)
I am using a Giganews Diamond account (unlimited with SSL)with the Giganews Accelerator. The server sttings are identical across all 3 platforms.
I used to get a download speed around 2Mbps on each of the 3 systems.
I usually only use on computer for Usenet at a time. Recently system #1 has slowed to about half that (i.e 1Mbps). I thought that perhaps I was being throttled by my ISP, but when I use either system #2 or #3 I get the fuil speed.
I am wondering if anyone can point me towards the reasons why this one computer gives a different download speed.
My home network is set up as follows:
Earthlink DSL > DLink Router > Dlink Gigabit Switch > Computers.
All of my computers (except my wife's latop) supoprt Gigabit networking, hence the extra layer (Gigabit Switch) in my Network configuration. Reducing the complexity of the network (i.e. pulling the Gigabit Switch out of the network and connecting directly to the router makes no difference)
Thanks for your help.
