I fear that someone is using my router

[Laughingman12]

My connection speed has been very slow while I am connect to my router. But my internet speed remain fine when I am using my ethernet cable without my router. I was thinking of changing my WPA key and upgrading it to WPA2. How do I get my computer to support WPA2?

First off, you should probably change your current WPA key.
Next, some routers will show a DHCP lease of an IP address to something accessing, check if there are some times or such that don't match.

So what if I find out someones been using my bandwidth?

Why don't you enable MAC address filtering? Then only your network cards will have permission to connect. Problem solved. (Other than for a serious hacker)
If you're speed is low while using the wireless adapter, maybe there is some bad interference affecting the router??

mac filtering is pointless...if someone broke his wpa key, they will have no issues spoofing his mac.

if hes using WPA and someone *is* still getting onto his network, finding and spoofing a MAC address will be a cinch for whoever it is, and a pain for the OP

change your WPA password. use wpa2 if your equipment can handle it (update all drivers if you must) and keep an eye on your router if the speed takes a hit to see how many clients are connected to it

of course, it may *not* be someone else using the network. is your router using up-to-date firmware?
