It all depends if you want to use an Openreach modem and a router or if you want a one box solution where you have a VDSLModem/router.
The cheapest method will be an Openreach modem and router. You could get an Openreach modem for under £20 and a router for not much more.
Once you have made your decision which method you want, do an Internet search and as long as you stick to big brand names such as Netgear, Asus, TP-Link, Belkin etc you won't go wrong.
I think a bean can and string out performs a faulty Homehub 5. It is difficult to say if it would be better without being able to carry out tests in the same environment. There is no reason why it should not perform well.
Well, the plunge has been taken. Dusted off the OR modem - unfortunately, an ECI jobbie - and called into PC World/Curry's and picked up the RT-AC68U, purely and simply because I have had enough. Just got it all connected up a few minutes ago, and so far, so good. Wireless seems stronger, and a quick Speedtest shows my download to be back nearer where it was - still a little way to go, but the whole system just feels quicker.
Next is to get hold of an unlocked Huawei HG612 and get rid of the unwanted interference from on high.
Suggest you keep an eye on the CRC errors shown - mine's not been stable and yesterday when I was testing with it, had 1000 CRC errors in 2 hours soDLM intervened overnight, added 8ms latency and dropped sync by about 10%.
Never had a problem with the ECI modem for the 18 months I've been using it before starting to think about changing to the DSL-AC68U.
There is a new firmware today for the DSL-AC68U, maybe not replicated around all the ASUS support sites which has new DSL firmware so may make it more stable.
When I first connect the Asus, my line speed went from 27M to 30M. However over the past 5 days, DLSM has kicked in and I am now down to 22M. This is with the latest firmware. Whats weird is that after a line drop it was re-syncing at 6dB and for over an hour no CRC errors. Then all of a sudden you could watch the CRC increasing whilst S/N was still at 6db. DLSM has now increased my target s/n to 8dB in order to compensate, so I guess I need to wait 2 weeks now for it to drop!!!!
Asus put back in box and going back to PC world later....such as shame.
