But apparently they can be tricky to configure. I also looked into a second Wi-Fi router, but I assume then you have two Wi-Fi hotspots? And have to configure your devices to connect to both? Icky.
Then something occurred to me. See those 3 antennas on the back of the router? What are they doing exactly? I assume they're all receiving in a spherical (or perhaps conical) space, but seeing as all 3 are stuck under my desk they're not achieving much. I noticed they unscrew easily and you can buy a coaxial cable like this...
...from online stores like rfshop.com.au. Specifications are:
|Connector 1||RP SMA Plug (Female pin)|
|Connector 2||RP SMA Jack (Male pin)|
|Cable Type||240 series|
|Ohms||50 ohm (TV coaxial is 75 ohm)|
So I ran one of the antenna up into the roof cavity and guess what? Now I get great Wi-Fi reception, even out in the garden! I still have only one Wi-Fi hotspot, and there was no configuration required. A bit unconventional, perhaps, but an idea for all you Do-It-Yourself-ers out there.
Update: I subsequently ran another 10 metre cable through to the front of the house, and it works equally well. I now get above 90% signal strength everywhere in the house.
