Billion Bipac 7800DX

I'm not sure yet if I need to try a new router or not (still need to try a new filter etc.) but, I'd like to know which to go for should I decide to try a new one.
I'm happy with the 7800n, but they aren't sold now, but see there's a 7800DX (Also a 7800DXL, but I tried one in 2013 and the Wi-Fi was very poor)

I've had two 7800n because when the first one gave up, I got a newer version with the 7800DXL but the wireless was really bad, and a known problem.

With these things in mind, I'd like to know which Billion model is likely to be best for me now (long line and happy with Billion)

Edited to put the correct model number in for a past router.

I'm on fttc and had a Plusnet router with a BT supplied modem. Decided to change and got a Billion 8800NL. This is a modem/router, so replaced two boxes with one. Happy with it so far.

Thank you!
Do you use the Wi-Fi for anything ..and if so, is it efficient?

Lots of wifi use. Plus a wifi printer in an upstairs room which gets a good signal.

Good to know - thanks!

There's a big price difference between the two.
