So I'm back to testing your 857 using ALL modes on WiFi, Short GI and HT20/40 is OFF and disabled. Turned off the cooler. Game play was ok however not sure if H4 servers and players were not working well, had a couple of games where single was in the Red. Woke up this am and iPhone had a good connection from what I could tell.
I'm wondering if maybe you should be using ALL modes instead of specific G and N mode since you have a couple of walls in between and more distances to cover.
Temps went up to about 108F this morning before I left. Ambient room temp was 65. I'll turn on my 2 APs tonight or tomorrow and test again. Alone, this router is working very well.
I have BO2 waiting for me at redbox after work so I'll be on tonight.
