Depending on what you’re trying to do with your wi-fi depends on why you’re trying to extend it – mine is to extend it across the street, I’d recently bought some TP Link 8db high-gain antennae, these worked “okay” but didn’t provide good enough support to “stream” anything with some drop outs.
I decided to go up a level and found some 9.5db high-gain antennae (+9.5dBi Omni 2.4GHz WiFi antenna with RP-SMA for Netgear, Belkin, Buffalo, D-Link, Alfa Routers & Adapters) which arrived this morning.
You can see a direct comparison of size between my old 8db high-gain antennae on the left and the 9.5db high-gain antennae on the right (these are large antennae anyway so the new ones are enormous).
Obviously fitting is pretty simple, just unscrew the old ones, screw in the new ones and it’s done – here’s what it looks like afterwards:
Yeah, pretty big – they’re all pointing different angles to provide a better almost-directional aspect to the signal.
Now, I have the ability to stream HD content across the street with a “good” to “excellent” signal, and obviously using a Netgear Extender provides an even better signal range over there (of course, with some loss of speed).
