How can I test my netbook's wifi receiver/transmitter, to eliminate it as a possibility in some network problems?

I'm attacking the problem from the other end (here and here), and it's looking as if the solution is probably to get a wifi extender. (The dropouts go away when I get close to the transmitter -- I think -- and the other wifi user isn't having problems.) However, I'd hate to drop some money and then find out I hadn't fixed the problem.

Is there a way to run some tests on the hardware, without buying anything (or very much) to completely eliminate the netbook as a culprit?

Specs: The netbook is an Asus Eee PC running Windows 7 Starter.

First, change your WiFi channel to 11 (the strongest) and see if that helps.

If it doesn't, as mentioned in your second link, use inSSIDer to map all signals around you. The problem can always be your neighbor's router, but also your new microwave or even metallic cupboards positioned between you and your router.

It's currently set to "automatic", wouldn't that choose the strongest channel? – neilfein Oct 19 '10 at 13:44

I refer to the channel the router is sending on. You have to logon to the router to change this. – harrymc Oct 19 '10 at 14:07
Yes, I'm using the router software for this, and it has an "automatic" setting. Screenshot – neilfein Oct 20 '10 at 3:22
Turned off interference robustness, switched to channel 11, will see id this works. – neilfein Oct 20 '10 at 3:27
Seeing definite improvement with channel 11 and interference robustness off. – neilfein Oct 20 '10 at 14:12

Assuming your hardware tests end up at best inconclusive, one option is to try a usb wifi adapter. They can be had for < $10.

Do note that it's entirely likely that whatever you're already using has much better range than any USB wifi dongle. ;) +1 – Billy ONeal Oct 19 '10 at 4:30
