Solution = N and repeaters. Oh, and WPA. (WEP can be cracked in a matter of minuets)
They won't help. You can see poor signal near router. The right solution is: use your neighbor's wifi. It should be green for you.
Use my neithbor's wifi - it's the best advice I've got ever!
The WPA protocol is not very secure, in 2008 it have been cracked. Any hacker can get TKIP key in 15 minutes
