Hi,  Extreme novice here. 

I have Vodaphone fibre  and the router they provided is terrible so i brought a TP-LINK - Archer VR2800 to ideally get a better signal that deosnt keep dropping out.  Unforuntately the signal strenght in my garage and garden around 15m away is weak / non existant and we would like to put an internet tv on the wall and ideally stream tv outside in summer evenings. 

Can anyone eiither recommend a better router that has a stronger signal over distance or someting that i can add to the currrent router so that i get decent internet outside.  If a new router is recommended it either needs to be a modem router or happy for someone to recommend a modem and then another router on top if this would work better.

Thanks

Brett
