An alternative for extending Wi-Fi
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.
