I am using the Asus RT-N66u with a Cisco modem, on a Comcast 50Mbps Internet connection. I have the router on the 2nd floor on one end of the house, and the distance to the other end is about 50'. All I have to do is walk down the staircase, and about 25' to the middle of the house, and my wifi signal drops. So I bought an Amped Wireless 1000mh external antenna which now enables me to get a consistent 2 of 3 bars on an iPhone 4s, and 4 of 5 bars on an apple TV. However, I am having an issue where random clients just lose their wifi signal completely. Then I go back to the connection manager, see the network which shows great signal, hit connect. Sometimes it connects just fine, other times it will say "Unable to join xxx network". If I reboot router, it usually works, or I just have to wait a bit, and suddenly it connects again.
Prior to this setup, I had U-Verse Internet with ATT's 2Wire router, and it worked perfectly, but I moved and had to switch to Comcast.
I am in range of about 10 or more AP's, but regardless of what channel I select, they all seem to be present. I have tried channels 1, 6, 11, and it does not change the number of AP's, nor does it help with my issue. I finally had to run an ethernet cable from router to Apple TV just so I could stream a movie without losing connectivity multiple times in middle of a movie. Any suggestions would be great.
