Hi,

I'm not particularly techie so please bear with me as I don't know what info is relevant...

We had problems with our Apple products (SE and X - subsequently SE is now 6S but still having problems, iPad pro, Macbook - phones worst though).  Issues were problenms connecting, and things timing out, or websites starting to load (small bit of blue line appearing) then getting stuck.  This was with plusnet fibre business and their router.  Decided it was probably the router since we had also had problems previously with apple products and a BT hub 5 (which looks exactly the same as the plusnet router).   So after looking at reviews bought a TP LINK Archer VR400.  

In all honestly, if there is any improvement it is minimal, still having problems with the iphones, which is immediately cured by switching off wifi and going to mobile data.  Used the mobile speedtest app and it almost always seems to come back with OK speeds, although it takes a while to start up, then does a low ping (20) the curve starts low then increases to steady.  Most recently I noticed the mobile app had a rating for jitter which I gogoled and seems high (it doesnt record it on thr results but think it was at about 300 - just did it and only 0.71 now, but problems not happening).

However, now getting new problems, for the last few months, regularly b ut intermittently having problems with lots of apps which feel like they are ones which communicate boith ways. like video calling, app store, email.  All giving variations of cannot connect to server.  It's getting extremely frustrating.  I've tried phoeing TP link, but they just tell me to go to livechat, I fill in the form and press the chat button, and nothing happens (like the button doesn't work).

I feel really stuck and don't know where to find answers, using zoom is a huge part of my business so I do need to get it fixed, but I'm a sole trader and don't know who to ask! 

Thanks for your help!
