I've had an unstable connection for a couple months now. I've attempted to research and correct this problem on my own but so far nothing has resolved it. I'm using ICS from a Win 7 desktop to a Win 7 laptop via a USB network adapter (on the desktop) and an ethernet cable. No router. The desktop's internet connection is fine so it's not the internet connection itself. I've also replaced the USB adapter and the ethernet cable but that did little to improve it. The symptoms, as far as I can tell, are: no recognition that there is any connection whatsoever; a recognized connection but with an unfixable error (things like "unidentified network", "no network access" and "no internet access". It varies); an apparently functional connection but with no actual function in practice (it says connected and it says it has internet access, but nothing loads and current connections such as Skype, etc. are lost); and different combinations of these in a row.
Some things seem to trigger it, such as streaming video (Youtube or Netflix), which causes an error sign. Most of the time though nothing at all seems to trigger it. And in the past few days Firefox freezes when I lose connection.
A few things temporarily fix it, such as removing and plugging the USB adapter back in, and disabling and reenabling the connection, but these only work for so long and sometimes don't work at all. The desktop's device manager does not indicate any hardware malfunction in the adapter during these times.
Having replaced most of the relevant hardware except the computers themselves, I'm guessing this is either some kind of Windows setting error or something else entirely. Someone suggested it was a virus, but Windows Defender and Trend Micro indicate my system is clean and I've had no other virus-like symptoms.
If anyone can help here, it'd be greatly appreciated. Thank you.
