Home internet connection failure
My ISP sent me a new DSL cable and microfilter, which got me back online for a very few minutes and then failed in its turn. They eventually accepted that I'd had that router for more than a couple of years and sent a replacement - but even that didn't work. Nothing in the router connection manual helped me to get online.
A helpful neighbour came round to check that my new connection worked for his laptop, then tackled mine. He tinkered with something - a programme in a long list (that I can't find) - which seemed to be about mobile connectivity. That didn't seem relevant to getting a laptop to 'talk' to my home router but it worked - until I turned the laptop off for a few hours!
So I went into Startup and scoured the list of apps there, found something with a different name that sounded as if it were about mobile connectivity for my Dell and turned that on, then restarted the laptop. That worked, fortunately.
Yet it hadn't been necessary while the old router was working. Is it common for different routers to need different software to be used on the same computer before the two can 'talk' to one another?
