Getting wifi in garage

I used net gear WiFi extenders and it did the job. The issue is the extender must itself be able to get a decent signal to work. The new sky q mini boxes also boost signal if you also have sky broadband.

TP Link are the best manufacturers for wifi boosters for residential properties. Not expensive. Plus they come with a Ethernet port built in to enable a hard wired connection no matter where you are. Easy to install when using the WPS button on your hub. No wires no fuss

There are various models and options, TP LINK as mentioned are well respected in this field. Personally I recommend passthrough devices, this means you don't lose the socket its plugged into. Some units are ethernet only and some are combined units. Speed wise I would recommend models AV500 and above. For these to work, the sockets do not need to be connected to the same ring main circuit, but to any ring main connected to the same consumer unit.

You will need to run a cable connection as far as possible then attach it to a Wireless Access point. Using 'wifi extenders' or Range extenders will only boost an already bad signal (missing bits of data due to loss) and be just as bad of a connection even if the device says it has a better connection. Your best bet for a cheap solution is a something from the TPLink EAP range. You want the kind of device that has to be cabled in then output's WiFi signal. If you cannot run a cable, you can use something called a powerline adapter which will send the network signal using your electrical cables. Then connect the wifi device to the other end. You can also get powerline adapters that have the wifi signal built into the far end, such as Mercusys MP510.
