Here's the deal. I have a router and modem upstairs, and it is sending signals to three other computers in the house with all have wireless USB adapters. Everything works fine 85% of the time. For some reason, they keep wanting to connect to our neighbor's router. Instead of linksys showing up (our router), it shows some wire24lan, and they keep switching and trying to connect on theres. and its causing trouble and staying-connected issues. But works fine, once I redirect them to the linksys router. Is there any way I can lock them onto the linksys I have upstairs?
Thanks.
P.S- It is running on an open network. So basically anyone can connect onto our network

Since we got it installed a year ago, I've never been able to figure out the whole wep thing and securing the network. (they only installed it on one pc via modem. We were left to buy the router and usb adapters , and do the networking....which has been half assed and open basically for the last year)
