As the title says, I'm having issues with Windows 8 connecting to my home network (Unidentified Network error).

The applicable segment of my network consists of the NIC wired to an Cisco WES610N bridge, which connects wirelessly to my WRT160N router.

The issue occurred after Guild Wars 2 froze, forcing a manual unexpected reboot (however, it may have froze due to a lost connection, I can't be sure). I have had this issue before (strangely enough, caused by an extra fan connected to the motherboard, directly next to the NIC), however my current setup has been running fine for some time and no changes have been made recently. Everything was running smoothly until the lock up and no settings have been changed in months. Below I've detailed what I have done thus far to pinpoint the cause.

Rebooted the PC.
I've double checked all of my network settings.
I've pinged the loopback address successfully.
I have tried to ping both the bridge and gateway, unsuccessfully.
I've power cycled all my networking gear.
I've run the automated troubleshooter (says the default gateway is not available).
I've switched to DHCP (I use static IPs) and back.
The link light is on when the cable is connected.
The activity light flashes when I ping an IP.
I've changed the CAT5 cable.
I've successfully run another system off of the same bridge using the same cables.
Currently, all of my other devices are running on the same router without issue.
I've installed a USB Wi-Fi connector and can successfully connect through it.
I've checked the Ethernet jack for damage (no signs of any).
I've uninstalled and reinstalled the NIC driver.
I've gone to Intel's site and updated the driver.
I'm currently running Malwarebytes and will run AVG Free afterwards.

Since my previous encounter with this issue seemed to be a power issue (and intermittent lock ups may suggest that, as well), I plan to order a power supply tester. I'm currently using an 800W power supply for an Asus Crosshair V Formula motherboard, 2 Sapphire HD 7870s in crossfire, an AMD FX8150 CPU, 1 SSD, 1 HDD, and a Blu-ray drive; in case that sounds insufficient to anyone.

I am currently taking a networking course where I can make a loopback plug (since I don't have the tools at home) as another possible test. If anyone has any recommendations or advice, I would greatly appreciate any input.

Thanks in advance!

For those interested, I seemed to be able to fix the problem by discharging the capacitors. Unplugging the system and hitting the power button, then plugging it back in and rebooting seemed to do the trick. I even had the same lockup cause the same issue and as soon as I discharged the capacitors, everything connected fine. I'm sure this is a rather unique fluke, but maybe it'll help someone else searching for a solution someday.
