This has nothing to do with the filesize. What you experiencing is that the driver itself is crashing under heavy load.
You need to uninstall the network driver first, then install it again and then reboot to fix the issue.
Before you uninstall your network driver, make sure you download the latest drivers first (once uninstalled, you won't have a working network, so you can't download it then without going through a lot of trouble).
You can safely install the downloaded drivers without uninstalling it first to test that the drivers will install okay.
Note to uninstall the network driver, do the following:
1. Open your device manager.
2. Locate your network card.
3. Right click and choose uninstall.
4. Restart the computer.
Seen this happen before, and this method fixed it. Hope it does for you as well.
EDIT: I see you haven't actually installed the network driver, so you are using a stock driver, which obviously isn't working well. You might get it fixed by just installing the right driver. To find the proper driver, just search for brand of laptop
type of laptop
drivers
windows 8
.
For example:
hp probook 4030 drivers windows 8
eventvwr.msc
on windows 7. No experience with windows 8 yet, but I suspect it is the same).
