Range Extension

Hi all,

I have an M50 package and want to extend the range of my wifi so that my garage is covered.  I have spent ages trying to understand the best options and I'll be honest I am probably more confused now than before.  I am not too fussed about speed, as you can probably tell by the package I am on, I just want usable internet in my garage which is not connected to the house.  I have a Hub 3 and am not looking to spend too much if I can help it.  Initially I thought Wifi Pods may work for me but the £8 a month seems quite a bit over time.  When I have looked at wifi boosters though they all seem to suggest that I would need to buy multiple items to essentially replace the router I currently have.  Not sure if that is correct or me misunderstanding it.  But if anyone can recommend a simple not too expensive solution then I would be very grateful.
