My router keeps showing a device on my network which isn't mine, but gets an assigned ip from my router. It only shows up occasionally though. When i first noticed it i think i was just using WEP security so i deleted the assigned ip for the unknown device and upped the security to wpa2 with a new password. However now the unknown assigned ip is back again showing up as 'active' on my router stats and then when i pull the plug on my wireless access point it then shows up as 'inactive' so im pretty sure its using the wireless access point. By the way i know its an unknown device as all my known network devices have reserved ips on the router and have been named.

I've also been getting an extremely high number of disconnections and line noise on my line, would this have anything to do with it? I can't see how myself, but me and my isp are really struggling to find reasons for it.

Any ideas on what i can do? Please help :(

---By the way im with O2 broadband on the 20mb package using a wireless II box (firmware 7.4.20.5) and my wireless access point is a netgear wg602v4, the wireless is also turned OFF on the o2 wireless II box so its not that. My network setup is via one ethernet port on my router to a series of homeplugs and network switches + the one netgear wireless access point.

Why don't you enable the MAC filter option? I mean, allow only trusted devices MACs to use the router at all. I'm pretty sure all routers have the option somewhere. Just involves getting the MAC addresses of all your networked devices and listing them on the routers config pages
 
sometimes they do.
also even WPA2 passwords are crakable if someones got the time and inclination to do it. leaving a PC with wireless sniffing everything passing it's way for a week or so and they will get though anything.
MAC filtering is bad as it can be spoofed.
turn off the SSID thingy so they can't see it so easly.
change the password every so often too.

It shows up as something like Unknown device 1354-2564-2876. Its not coming up now as i've been keeping the access point turned off for now. Still getting lots of disconnections though, got over 70 today o2 told me and that was at the test socket with the router plugged into a filter. Probably going to need to get an engineer out as i get a lot of noise on the line particularly when the nets up and running.

The only way to break WPA2 with AES right now is to brute force the passphrase, so if you don't use a crap passphrase the time to crack it would be longer than the universe has left.
 
You can also limit how many IP addresses the router will allocate can't you, so if you have 3 machines and you limit it to 3 then no-one else could get on ? Does it work like that ?
 
Use 64 random hex digits generated by a good, reliable rng as your WPA2 passphrase.

No one will be able to brute-force it or crack it (yet).

I recall having an odd device attached to my old speedtouch on Be, I think it was gateway coming up as a device which was a bit weird.
