I've been on this website before and you've always helped me out, so let's see if we can make it a third time!
Here's the problem.
I have a desktop (Dell Dimension 5100, Win XP SP3) i bought a few years ago. I use my laptop most of the time. The laptop works fine, the desktop is the one with the problem. It used to be able to go on the internet, but i left the country for about 6 months, i got back a few months ago and have only recently started to use it.
The wireless adapter (Bluenext adapter rt73 chipset) works fine in my laptop, but on the desktop, it connects to the router and the internet as normal for the first 30 seconds ( i can get to google if i'm quick enough) but doesn't appear to receive any internet connection at all and whatever was there at the start is now gone. I can't get onto the internet with Mozilla, IE, and nothing that needs the internet, like Skype, will work. The virus checker is out of date but still reports no viruses (AVG 7 free). If i restart the computer, the same cycle happens again, i'm able to get on for 30 secs but then it's gone again! Yet the whole while, the little icon in the tray says that everything is fine!!
So, doesn't sound like a router problem since the other computers work. Doesn't seem to be an adapter problem as it works in my laptop and other computers. Doesn't seem to be a driver problem as they are new drivers. I've not recently installed or updated anything new.
I've tried to have a look at the settings for the wireless network connection but everytime I do (and here's the weird part) i right click, press properties, the window opens up and i ALSO get the message saying:
Some of the controls on this property sheet are disabled because one or more other Network property sheets are already open. To use these controls, close all these property sheets and then reopen this one.
Now, i swear, there are NO other sheets open, this happens even after i restart the computer and it's the first thing i do.
If i right click on the wireless connection icon in the tray (bottom right) and press Status, it tells me everything is fine. Oh and here's another odd one... i can't even connect to the router by typing in http://192.168.0.1.
Any ideas? I usually know what i'm doing, but i can't figure this one out!!
Thanks for your anticipated help
