Unusual Networking issue

Long story short I can ping but can't browse, not just from one system, but from multiple systems. I can successfully ping from 3 laptops and 4 mobile devices and am unable to browse on any of them either wired or wireless. Its not a dns issue. I have spent hours on the phone with the isp to be repetitively told its not on their end.

Well, it sounds like a DNS issue. Just for the hell of it enter OpenDNS's servers into your adapter's DNS entries. 208.67.222.222 and 208.67.220.220.

Since this is WIFI have you tried a direct Ethernet connection to the modem?
 
IS it justa specific website? If so try checking your Antivirus protection, check the settings on blocking non secure DNS websites.
 
First thing I would try would be to go to a https site. If it works. Possibly the issue is only traffic on port 80. If it works but there is a warning message there might be something trying to proxy your connection.

Many home routers these days hijack dns and proxy web traffic during their setup phase or when they don't think they have an internet connection to direct you to the routers login. This can also be problematic for sites that automatically redirect you to their secure page. For example if you have ever tried to open up google.com at a McDonalds before accepting the ToS portal page. The page will just say no connection as opposed to an unencrypted site which will be redirected.

Next I'd try to ping with larger packets. Something like: ping google.com -l 1200 -f
The -l 1200 means 1200 bytes. The -f means to not fragment the packet.

Do you have your own router or is it a combo router/modem provided by centurylink?
