Wal,
I have 6 mb down/1 mb up service from local Cable company,
my setup is ALL G:
1 wired in 100 mb
2 wireless within 15 feet of router
2 wireless upstairs
when I check signal strength with 1.11 vs 1.21 wireless connections:
Ver 1.11 - 3 connections 100% 1 connection 90%
Ver 1.21 - latest Beta 1 connection 100%, 1 connection 87%, 1 connection 80%, 1 connection at 60%
I tried twice with basically same results, I did NOT move any wireless connecting in, all I did was reset and re-flash to the firmwares above.
Using Time Warner speed tests, ver 1.11 consistently was faster by .5 mb on d/l and u/l is the same as 1.21.
