Sometimes when my connection dies, my computer does a slight "hardware freeze." The sound jitters as though a BSOD is about to happen, mouse freezes, video freezes. This happens for 1-2 seconds, then returns to normal, except for being disconnected from the internet.
- I am using a wireless NIC plugged into a PCI-E slot on my motherboard.
- Sometimes I lose connection to the internet from my computer. There are usually no notifications for this other than I notice I am unable to browse the internet, or my dropbox green-checkbox-overlay disappears.
- I retain LAN connectivity.
- All other computers and devices retain internet connectivity.
- Given steps 2 and 3, we can deduce that I am able to ping a web site from my computer by using my router's admin page. This is indeed the case.
- I fix this issue by disabling and re-enabling my adapter (Windows 7). I do not wait after disabling my adapter; I immediately re-enable it. I do nothing else to the network at all.
- If I needed to check DHCP settings, or lease time, or any of that, why would I retain LAN connectivity?
- What is it that the NIC does upon being re-enabled that restores internet connectivity? If it somehow "refreshes" my NIC's IP, that would imply that it somehow got "stale" previously. Yet even in this stale state, I retain LAN connectivity! How/why? What is the core issue?
- Better yet: could someone explain clearly and simply (my networking knowledge is very limited) how this could be anything other than a driver issue?
