I am glad I bought this. The router offers two frequency bands.The TP Link support explained that the 2.4 GHtz has wider rangeand slower speed; whereas the 5 GHtz has narrower range but fasterspeed. (If you are close to the router go for 5, if far, for 2.4)My Mac laptop detects both the frequencies, but my Dell doesn't. Ditto,some phones detect only the lower frequency but some detect both. Ihave given different names to both the networks and now live happily.Everything said and done, this is a good router. It looks good, too.All my family members remain high on Wifi. The previous router, alsoof TP Link, had lots of Mac Validation issues and it stopped workingevery other day.How can anyone live without Wifi? One joke goes like this: A girlcalls her friend, 'Please stop me! Otherwise I will kill my boss!''Don't,' the friend said, 'jails don't have Wifi...' And it worked. Thatnasty boss is still alive.
