you can make YOUR router the preferred connection AND disable auto-connect to
non-preferred. These settings are associated with the Wireless Adaptor.

chklist:
1) disable SSID Broadcasting
2) enable encryption

 

sounds good. I'll try it. I already have encryption enabled. Does it matter whether I have a static IP or dynamic IP?

 

You should also check that your network on a different channel. It is best to have wifi networks 5 channels apart a la if the other network is 6, set yours to 1 or 11.

 

I'm quite interested in this as well, how is it possible to check the channel of a nearby WiFi connection without access to the router's settings ?

 

not at all

 

Uhm.. Tell your computer to scan for wifi networks and see the channel number in the results? That is you have decent wifi software

You can also connect to that network and see what channel your interface uses then.

 

The WiFi enabled computer in the house uses a Dlink WiFi card & the Dlink software is quite crappy. I just checked & I cannot seem to find where the network's channel is mentionned.

 

The Toshiba ConfigFree software shows the channel, {open/encrypted}, MAC
with a mouse hover over the ssid
