So there are a growing number of ways to get a wireless N setup at home- routers (airport extreme, Dlink855 or 655, SMC SMCWGBR14-N, Netgear WNR834B, Linksys WRT 150N, trendnet,others) or wireless access points (Dlink 1522, Netgear, airport express, as well as others). There seems to be a theoretical advantage to those routers and access points which work on the 5 ghz frequency but then you dont have backwards compatibility to all the other client devices that require 2.4 ghz. The mutant 'dual-band devices' have been spawned-some of which require you to select which frequency you want to use as well as those which have 2 radios in them and use both frequencies concurrently. I cannot seem to get a handle on which device gives the best throughput and signal strength despite reading a lot of stuff here, as well as at the dslreports website. I am leaning towards the Dlink 1522 AP. Since I have 2 ancient wireless b access points, my thinking is to replace them with wireless n access points that can fall back to 'b' and 'g' as well. But then you have the throughput gremlin-b/g drops 50% and n drops 30% when the same router tries to do both protocols.The alternative is to leave the ancient 'b' access points in place and to get the netgear AP which is 5 ghz only - simply add that to the network. or the dlink 1522 and turn off b/g? Any suggestions/experience to recommend a different solution/device? is there a 5 ghz router or AP worth getting that does N better than a 2.4 ghz device?
