We are with virgin media they recently installed a new modem router box that is working. I've checked on my laptop when plugged directly in to modem it works. The downstairs is working on and off. Upstairs my laptop won't connect to the internet and I'm cant get Netflix on the tv. I brought a TP link a year or two ago and connected cables from TP link to tv and laptop no problems a bit slow occasionally and some connection issues. Not sure what problem is or what to do or buy. Novice at technology.
