The range on one of my airport extremes is very bad. I asked Time Warner about it, and they said to "set up the channel settings to 11 and encryption settings to TKIP+AES". First off, I have three routers; one is the twc modem that acts as a router as well, and two airport extremes (connected to the modem obviously). They are on separate networks (means I have three different networks in my house). Second, the channel 11 is only for the 2.4GHz channel and they didn't tell me what to do for the 5GHz connection. Third, I can't find how to change the encryption settings to TKIP+AES. All of my routers, including the twc modem, are all on a different 2.4GHz and 5GHz channel, but I just did it randomly. I did that as when it was on auto, my connection would drop more often. If you guys could help me, it would be GREATLY appreciated. Thanks
