I need help from a network admin. I cant get this turd to connect to any network other than my home network.

Problem description: I typically connect this laptop to my home satellite isp network and use a vpn for work. The internet works fine at home on or off the vpn. When I travel I cant load the hotel internet login screen after connecting. My phone connects and browses fine. If I connect my laptop to the phones hotspot, it cannot browse the internet.

I can ping websites and recieve replies.
I can telnet to sites over port 80 and the screen goes blank as expected.

Attempted fixes: netsh int ip reset, netsh winsock reset, netsh http delete cache, dns flush, changed dns to 8.8.8.8, tried multiple browsers.

Recent changes: None.

Operating system: e.g. Windows 7 pro 64 bit

System specs: HP elitebook840 g3, 8g ram, i5-6300 2.4ghz

Location: usa

I have Googled and read the FAQ: Yes.

Do you have a proxy that's used for work? Thinking about it more, it's odd that it works fine on the sat without VPN but doesn't work anywhere else, but I'd still check proxy, if you do use one for work (or an automatic config script) turn that off and try to launch webpages.

Nah no proxies. Im wondering if the enterprise endpoint garbage is interfering. Its not letting me telnet on port 80 now so thats different from when I was troubleshooting. I may just send it back and have the IT goons reimage it or tell me if port 80/443 is truly blocked at the pc by their stupid poo poo. It may be faster to do that than to learn what I need from wireshark to see what the hell.

Oh yeah, it definitely makes sense that your work security software would do this.

Yeah, probably best to deal with your IT rather than random goons, since your IT will know the policies/security applied to your machine.

Try manually lowering the MTU on your NIC to something like 1430. Especially if it mostly manifests with HTTPS.
