Squeezebox dropouts - another question

There have been many threads on this and I have tried to read them all, but I still have not solved the problem. I just bought a fancy-dancy dual band (2.4 and 5 Ghz) wireless Netgear router (N900, E4500). I use this to stream music to a Logitech Squeezebox Touch. I still get dropouts when streaming 96kHz files. The router is 20' line of site to the SBT. The SBT says signal strength is 100%. If I connect the SBT to the router with an Ethernet cable, everything is fine, no dropouts. I would prefer to go wireless for convenience and noise isolation. Any other suggestions? I have not been able to figure out how to change buffer size settings on the SBT or the router. Are there other settings I can try? Any help is appreciated.
