Help, can't stick on to my network.

[MaMister]

I have a wireless router which I have setup wep and ssid. It can connect perfectly well and surfing and so on.

It happens when my neighbour or don't know where comes another network without security and keeps rushing to get my computer connected... I tried prefer network but after a while my network will stop and switch to my neighbour....how to do ??

Try changing the SSID in the router and on the lappy first, make the router only accept manually added MAC addresses than add yours as another option.
