WiFi coverage over through the house!!
First thing which springs to my mind is could it be a faulty router?
You're going to have to test a few things to narrow this down. You mentioned the speed is poor on wireless (when you can get it). It may not be convenient, but you need to test a wired connection with your computer and yes I know that might involve moving it. Ideally in the master socket and also check there is no noise on your landline too. I'd make a test call or dial 17070 and do a quiet line test (option 2).
Yes I know a song about that. 
If it makes no difference and the speed is still poor, PlusNet can perform tests on your line just make sure the router is on.
Hi @Myasophie, thank you for getting back to us. I have tested your line this morning and the drops we saw towards the start of last week were certainly concerning and could be signs that there's a underlying issue.
Although the connection has looked to be much better starting from the end of this week, when testing your connection we were seeing the speeds have been banded. This is more than likely due to the automated line management making changes to help prevent further drops. It's capped your speed between 3-6Mbps which explains the 4Mbps or so you've been seeing your side and I have taken steps to get the speed cap removed for you. Hopefully from here you should see increased speeds however this may result in drops continuing with the connection as a whole moving forwards. As there's convincingly a underlying issue occurring with your connection I'd advise we look into getting to the bottom of this before exploring wireless improvements as any monitoring or tweaks when changing wireless settings can be easily by misjudged by overall connection issues.
My changes to your connection and speed should come into effect straight away and if you can please monitor throughout the rest of today to see if the drops persist or not. If they do then we'd recommend running through some troubleshoot steps as seen below:
Can you run through our troubleshooting guides here, let us know how you get on: http://goo.gl/p2tpvL
If you do notice the connection dropping (broadband light goes out) over the next few hours then one of the key troubleshoot steps would be to get the router in the optimal set-up and then seeing if the issue persists. This rules out internal wiring such as the face plate, extension sockets and wiring to other sockets as being the problem. For steps on how to locate and set-up in the test socket you can check here:

Please let us know how the connection goes over the next 24 hours or so, how the troubleshooting goes if need be and if the speeds have jumped up somewhat and there's no further drops then I'd recommend now beginning to optimise your wireless with all the settings on our side where they should be. Let us know how it goes.
Hi @Myasophie1980,
Your line seems to be alot more stable (the drop at 13.30 today was my testing) and everything seems to be fine.
If you're still having problems I would suggest trying the other wireless channels, not just 1,6 and 11. It's a bit of trial and error but usually perseverance is worth it. I myself am currently sat happily, for the moment at least on channel 8, but that wasn't without trying channels 1-7 before this.
The other thing I would suggest and I know someone touched on this briefly, but try connected via a wired connection with a device to your router and see if you are still experiencing an issue. If not and the connection works fine then its almost certain that the problem is wireless.
From that point, if none of the channels help, then either signal boosters, powerline adapters and using a wired connection to things like computers and TV's may be the best means of a solid, reliable connection.
