Currently i have a wifi router downstairs, but its signal is not strong upstairs. I have tried a variety of routers and they don't seem to help.
I have a pair of 200mbit homeplugs which connect my computer upstairs and i get a 50megabit connection there which is reasonable. However i would like to connect 3 wired devices in my room, i think a network switch would be okay for this however i would also like to improve the wifi signal upstairs.
What hardware do i need to buy that can act as a switch and a wifi hotspot, using the homeplug connection i already have?
