The context: I have a nightmare internet connection (slow connection often below 2Mbps, frequent disconnections), despite living in a newly built property where all neighbours are getting a decent +10Mbps connection. My ISP, Plusnet, has gone round in circles for 6 months and is still unable to fix the issue. They've ruled out cabling/telephony issues, connection settings and cabling from flat to the nearest green box (after +10 BT openreach visits). They're now saying that there is a high chance that the issue is caused by their own router-modem, which causes the connection to 'trip'. At the same time they're refusing to replace is free of charge or to do any checks at the telephone exchange. I've purchased my own router (Asus RT-N66U), but cannot connect to the broadband as Plusnet's connection type PPPoA is not one of the options of this router. This means I'm back to where I started: there's no way to see if this is indeed a router issue or not, Plusnet refuses to do anything else and won't help me configure my own router.
I'm thinking of changing provider altogether, but I'm not sure if I will inherit the same problem that I'm experiencing with Plusnet. The question I have is the following: does a new ISP make any hardware changes at the exchange? I have been told of a 'lift and shift' hardware change procedure. If this is something hey do as part of setting up a new user - then I basically just need to change ISP as the possible issue at the exchange would be addressed and I will also get a new modem that I can use with my router. Could anyone help on this?
Much appreciate any advice.
