Need new modem

[ForeseenVisionz]

so ive been using the technicolour tg582n for a while but recently i hard reset it ( with the pinhole),

and it wont work no matter what we do and now we are using this old dlink one, 

which has dropped our speeds

from 17down and 1up (all in kbps unfortunately )

to an ever shitter 5(or less)down and like 0.01up.

and it doesnt load most pages and wifi doesnt evn work evn though its connected.

so please,i need a new one that can maintain good wifi signal throughout the house,

its pre big so the old one didnt evn used to reach the back barely.

and one that can maintain those speeds (probs not very hard lol)

i need it fast because as you know u cant do anything without the internet lol

for budget well im sure nothing will be too much anyways so thats fine, any help is appreciated, cheers
