Networking & wireless: Inconsistent Internet Speed
Inconsistent Internet Speed
by Jaydoc1999 - 7/4/09 6:57 AMThanks in advance to anyone offering suggestions.
Comcast 6Mb/s service > Cable modem > Linksys WRT400N > Linksys WRT150N (acting as access point)
WPA2 security
Two computers in the same room both connected wirelessly have drastically different internet speeds as tested at multiple speedtest sites including CNET's.
My gateway laptop gets speeds of 18-20 Mb/s while my desktop (with Linksys WMP300N card) gets 1 Mb/s 19 times out of 20 with the other one being 18-20 Mb/s. Interestingly the upload is consistently 2.5 Mb/s on both computers. Connection per windows is 270 Mb/s with "excellent" signal strength on both.
A third computer (also with a WMP300N card and older firmware) in a different area of the house gets 18-20 Mb/s.
I have cleaned/repaired the registry, eliminated unneccessary startup items, run adaware, updated virus software and run it, checked the hard-disk, even done a fresh install of XP with SP3, updated mainboard drivers, run DSLreports speed optimizer as well as System Mechanic's speed optimizer, all without improvement.
The slow system is XP SP3, AMD athlon 64, 2 GB RAM if that matters.
Please help, I've been wrestling with this for over a week.
We have a post about that.

The member found that flipping it all to 802.11g only and using our forum's basic settings helped.
BUT the internet speed tests SHALL ALWAYS VARY. This is the way of the internet. If you can't accept that, then we have to wait till you learn more about the internet. Once you accept that tests DO VARY then your tests should be with the more stable connections and you toss out the high and low and take the averages.
There are MACHINE ISSUES beyond my first sentence. Someone might have installed Norton plus adaware or other TOXIC combinations. YOU have to reveal the combinations since I will never be able to post all that I've found.
Good luck,
Bob
Slow connection on one computer of the network.

I understand that tests will (and do) vary. But the test results are consistently different between my one desktop and the other computers in the house. I did a clean install of windows XP to try to take software out of the picture, and even then the desktop in question was consistently 1/20th the download of the others.
Have you/anyone heard of nForce drivers contributing to network speed issue? The mainboard I am running is an MSI nForce 4 board and when I did the clean install of XP, the only software I installed was XP SP3, required drivers for the mainboard (nForce 4 as above including a RAID 0 array), and drivers for my linksys wireless card.
Yes to nforce.

Especially the nvidia firewall.
About 2 machines and they don't match. Detail what differs and move them to closer configurations. Also do your test with a more consistent OS like Linux.
And again. Wifi is not a good idea for these tests.
