Wireless network not validating

08-Jul-2016 04:48

I recently bought a new Linksys wireless router and after setting it up with basic WEP security, I tried to logon from my laptop and was successful! So then I tried to connect from my desktop computer that has a wireless USB adapter attached to it and I ended up getting this error message: Fabulous! I checked my settings on the wireless router to make sure I didn’t accidentally setup certificate security, but found no such thing.

EDIT (for bounty) I keep trying the same things as listed above, hoping something will just magically work, but it's proven unsuccessful. I know the best solution would be "Just reinstall Windows", but right now that's not a possibility.

After doing close to the same steps that you have done, I did these things: In my case it was simply that Windows Update had installed the newest driver for the NIC and I needed to rollback to a Vista version of the driver.

The odds are somewhat against drivers for both of these devices becoming damaged at the same time.

Try looking at the Event Viewer in the System log for any error or warning messages related to networking, then Google any you aren't sure of. You can revert the computer's settings to a point prior to the issue appearing (or several weeks back if you don't know when it stopped working).

The issue is probably not a software one but a hardware one.

Unfortunately, I am not intelligent enough to explain the reason that the 'updated' version of the driver failed.Also, SFC failing may be some foreshadowing of a larger problem or it could actually be the problem. This definitely sounds like a driver issue, but the fact both your wired and wireless connections don't work suggests the problem could be something else.If this doesn't help you can always "undo" the System Restore.SR doesn't harm user-created documents, e-mails, etc.

go into CMD (command prompt) and type this: netsh wlan connect name="name of network trying to connect to" use quotes if the network is more than 1 word.Also try: netsh interface set interface name="name of your wireless/wired adapter" admin=enabled this will manually enable the adapter.
