I have a Dell latitude D820 Laptop.
Worked fine for the last 3 years.
I connect to the internet using a broadband modem from 3.
Last week I downloaded and installed AVG anti-virus, but after that the modem did not work any more.
So I uninstalled AVG, got a blue screen, restored to last good settings, but still no internet.
I checked the Microsoft forum, which pointed me to hardware device manager, and there were 4 yellow circles.
So I upgraded the drivers for these, and eventually fixed three, including WI-Fi, which had gone missing.
But I just cannot seem to fix the RAS Async adapter, and I've tried everything.
It wont uninstall, wont update, disables but makes no difference, etc
And I suspect that the broadband modem will not connect until this is resolved.
Help!!!!!!! (I am using my daughters computer to try to solve this as I cannot log onto the internet)
