Due to recent failure, back using the old Speedtouch ST585.
I have an old 3 floor stone wall house. Main phone socket on ground floor, computer currently wired to ST585 via an extension on first floor, as figure wired via a (probably poor quality wire) extension is better than wireless from the floor below, given the equipment. Wireless use now for occasional laptop and mobiles. Area only has max 8MB line at present (rural location) but I'm only 50yards from the exchange. Most usage web browsing and some gaming.
Advice on upgrading the equipment, please. No point getting all the bells and whistles kit given the line restrictions, just something fit for purpose and some install advice.
