So, I bought the new Extreme yesterday afternoon sort of spontaneously and got it hooked up earlier in the evening. There were a few issues, but I got it sorted out. What's confusing me, though, is that according to iStumbler my 2.4 channel is so-so, as one might expect in a crowded urban area like where I live, and my 5ghz is stunning, but on both my Roku, which is in a bedroom on the same floor as the Extreme, and on my LG Smart TV, which is basically directly below the Extreme one floor down, the 2.4 channel shows up as full bars excellent signal while the 5ghz shows up as mediocre. My previous router was single band and I was hoping to use the 5ghz channels specifically for media streaming. Neither of my AirPlay stereos can apparently see the 5ghz channel. How can iStumbler and my Roku and Smart TV be right simultaneously with opposing results? Is there an issue with the 5ghz channel extending beyond the room the Extreme is in? Should I exchange it for another? Thoughts? Thanks.

    That would be because 5 GHz signals are much weaker than 2.4 GHz signals. So walls, ceilings, and any other obstruction in the signal path will absorb the 5 GHz signal much more quickly.

     

    You have to think of 5 GHz pretty much as a "same room" or "line-of-sight" deal for good performance.

    So, the only real solution to that would be to get an Express or the like for the living room or bedroom?

    Yes, but even then, 5 GHz may not "extend" well at all if you are trying to use wireless to repeat the signal. You really need to connect the AirPorts together using a wired Ethernet connection for good results.

     

    Can't help on your other issue. Please start a new post for that.
