Windows 7: Network Discover and auto-connect slowing internet to 0

so heres the deal

can and do connect to my personal network no problem.

at night when signal strengths are greater, i get a "lynksis" network that appears and disappears as available pretty much every 15 seconds

i highlight the "linksys" in wireless connection manager on taskbar and un-check "connect automatically"

internet is normal for 15 seconds until the same "linksys" network appears, since it disappeared and then re-appeared 7 sees it as a new network and then "connects automatically" screwing and damn near disabling my perfectly functioning home network.



repeat

thing is that i want to turn off broadcast OR find a way to prevent the network center from connecting to any old network it can find, especially ones that i dont even have info for.

please help it is driving me mad that my internet pretty much doesnt function at night....
