I have noticed over the last month that my access to certain websites (as example www.msu.edu) and certain other sites within this domain do not work. When I click on website I get a time out error on browser. I have used several browsers and get same response.
When I go to website via my cellular phone cellular connection it works fine, then when switch to my home WiFi i get the error. Further, when i connect through VPN on my work laptop through home WiFi it again works fine, but when disconnect VPN and go through work laptop on home WiFi i get same error.
Given these facts I am assuming this is an issue on Xfinity end and I have called/texted them several times with no solution. The only response i got was that my modem must be blocking the sites. Because i have my own modem, they directed me to the modem provider who I called and explained situation and modem provider noted it was internet provider issue. Thus I am getting caught in middle of the two each blaming the other. Given i can connect through VPN, I do not believe this is something in my modem or router but again rather an issue on Xfinity side.
Any help or thoughts would be greatly appreciated as it is really annoying to have to switch to cellular hotspot or VPN to access these sites when desired. I have tried many items I was able to see on net as IP renew, reviewing DNS settings, etc. without any luck. Thanks in advance.
