I lost the ability to connect to certain site when connected to cisco vpn and on wireless. I'm on windows 8.1. I have no problem from the same wireless and cisco connection on a windows 7 machine.  I get the page cannot be displayed with all browsers. I can access certain client page but not others.  This issue occurs only when I'm on wireless. I have no problem using an wired (Ethernet) connect. 

Below are some specific scenarios.

Windows 8.1 Wireless connection (have to be on vpn to access the pages) - ISSUE

- Can access a site or 2 but most cannot be accessed

The issue started about 1 month ago ( I don't do regular windows update. Not sure if an update broke it or something else. My updates are now up to date)

NOTE: I have the same issue connected wireless thru my phone (phone as a hot spot) and other wireless network. 

Windows 8.1 wired internet (Ethernet) connection (same router as the wireless) same vpn connection as above

- No issues, can access all needed pages

Windows 7 Wireless connection (same as machine on windows 8.1), Same vpn connection

- No issues, can access all needed pages

I have tried many suggested fix. Nothing works.  I desperately need help.  

Thanks
