A1's definitely do not like 1.2x, 3 out 3 routers all purchased at the same time hate 1.2x i've got 5 days under my routers belt. I tried the same firmware on the 2 other routers same results "crashes every 4-5 hours","Hate wifi N spotty even close to router","Gamefuel unusable 4% average packet loss" hmmmm maybe your house is very cold or something of the sort.
