There is a lot of work being done to 'fix' WEP - Cisco's LEAP is pretty good (and considerably easier to implement than IPSec) but their kit is always expensive. Symbol now use Kerberos. The main players use EAP which allows for a reasonable security level for a home network - dynamic key allocation helps, although it still relies on RC4.

The 802.1x standard looks good, and most of the vendors are buying in to it, preparing their firmware for upgrading as and when it happens.
