After having lots of issues with 18.104.22.168, TAC is suggesting that I use 22.214.171.124. I have 6 production 4404s and 1 test 4402. I have wiped the config on my 4402 and loaded 126.96.36.199 code. I want to test all of my applications before trying to migrate everything over. I cannot get any APs to associate to the 4402 runing the 4.2 code. I suspect that since they are now looking for CAPWAP controllers, they aren't connecting to the LWAP controller now. Any ideas?
