> We are on the fancy new fibre stuff, and it's useless!! We don't know if it's the line from the fibre to our house that's rubbish or the router etc. However, we just don't need a line if mobile is sufficient and the deals I am finding are cheaper.
My partner got upsold to an expensive fibre deal when we called for the umpteenth time to report a line fault and crap internet. The fibre stops halfway up the road, the rotten decades old phone lines that crackle in the weather are the problem so obviously the premium product was still crap. I was fuming given it wasn't the first time they'd had to fix cable faults, they just scammed her while she was stressed about having remote access to her uni work. Eventually I got that scam cancelled and a tech came out to find the best remaining pair between us and the roadside box. Worth persevering and having a chat to the guy or girl who goes up the pole, you'll probably get a straight answer from them.
If your WIFI router is set up right it should, at least when you're in the room with it be significantly faster than your internet (I assume it's not fibre right into the house/flat). I haven't looked in years to see what manual settings if any are still available in bundled router/modem units to screw up a link, I suspect almost none. There could be interference but I'd be surprised.
It's probably not your WIFI but you could test that a few different ways. Simplest is probably run an internet speed test over WIFI then repeat with you laptop plugged into an Ethernet port (WIFI off to be sure it configures and uses the ethernet link). It shouldn't be any different though you might need to take the averages of a few readings each way to be sure if your internet is as bad as mine was.
No idea what the mobile hotspot deals are like, I suspect it's very much buyer beware and worth doing your research into the particular deal you're considering. My 4G phone isn't up to much beyond low-medium res youtube most of the time, fine for web browsing and killing time in a queue but I'd find that pretty frustrating as my main source of home entertainment.
