I just bought a new desktop and the wireless connection it finds with my router is very weak to the point that it drops out every few seconds, even though I'm about 2m from the router. The maximum wireless I get is 2 out of 5 bars, but when the wired connection is disconnected the wireless connection drops even further!
The desktop runs Windows 7 Home Premium 64-bit and has a 802.11n Ralink wireless PCI express adapter built-in. The router we use in my house is a D-link DSL 2640r (802.11g). I had an old dell laptop in the same position as my new desktop which ran fine wirelessly, so location is not the issue.
The security on the router is WPA and I've logged on to the router to try different security settings and channels to no avail. On the adapter end, I've tried to update the driver (no update found) and the roll-back option is greyed out. Several different OSs and machines in the house (including a Win7 laptop) connect fully to the wireless network but having real problems with this.
I have seen an awful lot of similar problems to this around different forums- anyone aware of a fix or at least the cause of the problem?
Thanks in advance
