post #1 of 5
Thread Starter 
I dont know whats going on but my wireless network card is acting up. I open up windows and watch the link speed keep changing on me until it drops to 1mbps instead of the usual 144. Please this is so frustrating i cant use anything (internet) on my computer!!

Wireless connectivity issues are extremely difficult to diagnose remotely. You need to provide at least SOME basic information for anybody to help. For starters:

1. What kind of WiFi card are you using, is this in a desktop? Laptop? Mac? PC? Who knows. You gave no information at all.

2. How far is the wireless router from your computer? Are other wireless devices working OK and just one device is failing?

.... OK buddy since you ask so nicely here is your info. The reason I'm not uploading screen shots from my host computer is because I can't!

1. desktop trendnet 620 Wireless N PCI card. Used for years without a hitch. 2.4Ghz

2. About 9 feet. Yes I reset modem and router. Only my desktop has issues

Decent enough wireless card, and wow - 9 feet, shouldn't be any interference issues with such a short line of sight.

Only thing I can think of is you could have some malware running in the background like a DNS DDoS attack Trojan or something like that that's sending a large number of tiny TCP/IP packets - which causes flooding on the WiFi connection and drops bandwidth to near-zero. If you're running Windows 7/8 you can check performance monitor (open Task Manager, click performance, open Resource Monitor) and click network tab and see if there's a process that's continuously sending packets.

You might be able to set up a Linux LiveCD with Ubuntu or something similar that supports that wireless card and see if the network issue continues with that. If so, it's a hardware issue. If not, it's a software/driver/malware issue.

Does this happen on all non overlapping channels?

Sometimes it is hard to diagnose without a spectrum analyzer.
