I've had a Dell Inspiron 620 for less than a month. Because I found Dell's onboard wireless less than useless (IF it picked up the signal from my TalkTalk router it usually dropped out after a few seconds) I installed a Netgear USB wi-fi dongle which I'd previously used with no problems on an XP machine.
My annoyance (rather than problem) is that the Netgear doesn't always fire up first time when I switch on the PC. This is solved by briefly unplugging the Netgear's USB for a few seconds and then plugging it back in.
This is an annoyance rather than a problem but I wonder if members might have suggestions or a fix so that the Netgear fires up first time every time.
The only available option in the Netgear's power settings is "Allow the computer to turn off this device" which is de-selected.
I'm loathe to update the driver but any suggestions will be welcomed.
The only other thing I can think of is when you sign in to the wireless connection using a password or username for the first time I am sure there is a box on there that you tick to say keep me signed in.
Not sure that's your problem though but thought that I would mention it.
Not sure if you would need to switch off the wireless connection on the laptop as you do not use it.Now you obviously need the Dongle to run at start up so check in msconfig to see if it is ticked on there and the laptop one unticked.
If I remember right my daughter has D-Link on her start up programs.Will check tonight when I am up there.
