Hey, my PC has been having problems connecting to the internet, off and on, for about the last month or two. Specs:

Router: 5031NV-030 (Frontier Communications; wireless; between one and four devices connected at any one time)
Motherboard: Intel H87
Power Supply: Peak 400W/Peak 500W (can't find exact model, sorry)
Network Adapter: Realtek 8821AE Wireless LAN 802.11ac PCI-E NIC
OS: Windows 7 Home Premium SP1
CPU: Intel Core i7 4770 (3.40 GHz)
VC: nvidia GeForce GTX780
Harddrives: Kingston RBU-SC4 SCSI Disk Device and WDC WD5001FZWX-00ZHU SCSI Disk Device

Connectivity goes downs once every two weeks (infrequent), and only for brief periods of time - generally, when I notice that I cannot log on to any websites, I just have to click the Troubleshoot option on the Network and Sharing Center, and an automated reset of the networking adapter clears the problem up. On at least one occasion, the self-diagnostic suggested that "a connection may be loose".

This morning, I woke up to find my network connection had crashed overnight while dling some data from Steam, and this time, resetting the adapter did not help. (I know the problem lay not with my router, as Wifi was working fine on my other devices, e.g. my laptop and my phone) What makes me wonder if something else might be going on, is that I tried to reboot my PC, and when I did, Windows "hung" for at least ten minutes on the "Shutting Down" screen. I had to do a manual hard-reboot, and after that, everything is working fine - computer restarted in seconds, and the network adapter was easily reset. Could be a totally unrelated problem, mind you, so: advice? What should I do next?
 
Solution
Open your case and double check that the PCI-e network adapter is fully and securely seated in place. Check all other components and cables as well.

Check that any antenna connections are securely in place.

Download and reinstall the latest drivers via Realtek's website.

You should also backup your data and verify the that the backups are working.

Just as a precaution if there is some other developing intermittent problem: e.g., disk drive, PSU, contributing to or initiating the problem.

And if you open the case you should be able to find more information about the PSU including the model number.
