Have you reset the browsers?
Dafydd.
Chrome and Firefox often stop responding while I am trying to use the internet. It only happens on my laptop when using the connection from my new router (other devices work fine). The laptop shows that it is connected to the internet but I sporadically can't browse on chrome. The laptop always shows a strong connection and diagnostics doesn't show anything. My laptop works fine on other networks.
I have Windows 10, my laptop is a Dell Inspiron,just bought it around a year ago.
