Home Network and ics problem

by GoreSmasher / January 21, 2017 6:06 PM PST

I live in the country and get my internet from an AT&T aircard. My configuration was enabling ICS on the cellular connection and sharing it with a wired Ethernet to my router which provided service to TV, Xbox, receiver, and directv box. This configuration worked until I upgraded to a new computer. Both computers are windows 10. The router on the new computer connects to the net for like 20 seconds then drops the connection. I've bypassed the router and have gone straight from Ethernet to my smart tv with a different Ethernet cable. It does the same. Grabs an IP and connects for like 20-30 seconds then drops it all. I've disable all firewalls. I've upgraded network and chipset drivers. The cellular and nic are grabbing the correct ips and so does the router until it drops. Any ideas? I created an account here just for this. One idea I have is that my aircard is a USB2.0 device and even when I have it in a USB2.0 port, the trouble shooter says it's in a 3.0 port. It holds the connection and the internet on the actual host computer is fine. PLEASE HELP

Clarification Request
I worry the AirCard is too old.

https://www.att.com/support_static_files/manuals/ATT_UnitePro_AC781S.pdf was from nearly 4 years ago.

I don't see an exact model so I can't see if there are open/prior discussions about this setup.

Even so, I think such use is nice when it works but no one I know supports that setup. That is, you have to go with what you can do to fix it. Even if it takes a complete wipe of the host PC's HDD and a fresh install or new gear.

Not old

They still support the card, but not sharing/ tethering/ hotspot on an unlimited plan. I've already restored the OS. I've also tried it with the old PC that it worked with. It's also dropping the IP. The only PC that stays connected is the host. I'm thinking the ISP is maybe somehow seeing other devices. I can't activate hot-spot in windows because I'm unlimited.

At least that works.

In the manual under "When you select a Wi-Fi profile, consider
the following table to choose the correct
profile for your setup." it appears to have a way to share the connection natively.

If you can't figure out how to use ICS, at least you can use a hotspot.
