Hi, 
You can refer to this blog, and try to roll back to the older version of network adapter driver to check the results. Other suggestions can also be used to troubleshoot your issue.
Windows 8.1 Wifi showing "limited" or "No Internet Access"

Meanwhile, please check with the manufacturer of your router to update the firmware.
If the issue persists, please help to collect following information for further research: 
1)            Enable RAS Tracing on the client. 
-              Over an Administrative command prompt. 
-              C:\> netsh ras set tracing * enabled
2)            On the client enable the following log as well:
-              Over an Administrative command prompt. 
-              C:\> netsh trace start scenario=netconnection capture=yes tracefile=c:\net.etl
3)            Now, turn off Wireless adapter on the client and Turn it back ON for making it to authenticate. Once it fails to connect to the Wireless network, proceed to the next step.
4)            Disable RAS Tracing on the client. 
-              Over an Administrative command prompt. 
-              C:\> netsh ras set tracing * disabled
5)            On the client disable the following log as well:
-              Over an Administrative command prompt. 
-              C:\> netsh trace stop
6)            Please provide the following files:
From the Client:
a)            ZIP folder of C:\Windows\Tracing
b)            C:\Net.etl and C:\Net.cab
Upload these files in SkyDrive and post back the shared link. 
Keep post.
