An al­ter­na­tive for ex­tend­ing Wi-Fi

Mac Format - - APPLE TALK -

With my third­gen­er­a­tion Time Cap­sule, one can­not ex­tend an ex­ist­ing Wi-Fi net­work un­less an Ap­ple router, such as an Air­Port Ex­press, is con­nected us­ing Eth­er­net to the broad­band mo­dem. I be­lieve this is a com­pat­i­bil­ity is­sue with non‑Ap­ple routers. As my router’s Wi-Fi sig­nal can­not reach the ex­trem­i­ties of my house, I’m us­ing a re­peater to ex­tend the sig­nal, which kills net­work speed. My Time Cap­sule is half­way be­tween my router and the outer lim­its of my house, so will I have to at­tempt the Ap­ple so­lu­tion by us­ing an Air­Port Ex­press? Arthur Dardalis An­other op­tion is to use Pow­er­line net­work­ing to bridge some of the gap. This tech­nol­ogy sends sig­nals through your do­mes­tic wiring by mod­u­lat­ing the fre­quency of the AC elec­tric­ity sup­ply. It’s quite invisible to or­di­nary elec­tri­cal ap­pli­ances and has a the­o­ret­i­cal band­width of 500Mbps, which is faster than most Wi-Fi net­works. It’s a pretty ma­ture tech­nol­ogy now, though I wouldn’t rec­om­mend it as a re­place­ment for Wi-Fi since it’s more re­stric­tive and no use at all for mo­bile de­vices. It’s a great way to fill in Wi-Fi blackspots.

Net­gear’s XWNB5201 is about £70, for a pair of re­peaters. You plug one into a socket near your router and con­nect it with an Eth­er­net ca­ble. The other can go any­where in your home (on the same cir­cuit), where it will re­broad­cast the Wi-Fi sig­nal.

Pow­er­line net­work­ing reuses your home’s elec­tri­cal wiring.
