I have been having this issue for a while. I have never had an issue with wifi till I've tried to connect to my school's wifi. I have windows 8 and the above wireless adapter. I have re-installed the driver twice, once completely removing the drive and all files using the device manager then installing, and finally restarting. No one else I know has this issue and my phone connects to it fine. Windows 8 will constantly say that I don't have a valid IP configuration, and sometimes that the default gateway is not accessible. Half the time troubleshooting and it resetting the wireless adapter will get it to start working again. Sometimes it won't even work after a restart. It seems pretty random and the only sure way I know of to reproduce the problem is to do a regular shutdown then boot back up. Does anybody have any ideas?

First is a screenshot of weird ping action when I try pinging the router. Second is a couple of event logs I found that may be related. Last is a screenshot of ipconfig which was asked for below
