Here's the problem. My Desktop has full internet access, e-mail, web browsers html, FTP, etc. But lately my Android devices are only partially internet connected. By this I mean I can use email apps, and apps dedicated to a specific task i.e. Facebook, You Tube, T-Mobile. These work almost flawlessly. But, regardless of the web browser I use I can only access some web sites. I can access Earthlink but I can't access Amazon.com with either Firefox, Chrome, Dashlane, Opera Beta web browser apps. I can't connect to many websites receiving various error messages. Not Found 404, Timed Out, The Proxy Server is Rejecting the requested website...etc
I've run anti-virus, anti-malware on all devices. They all come back clean.
I haven't changed configuration since I got everything working with this setup a year ago. Suddenly the Phone and Tablet can do everything but access the internet via Web Browser.
