You needed to connect to your new house because it was the only choice available. Currently, you're getting 12 megabits per second—which isn’t great—but that’s not the main issue. The ISP router seems to be blocking shared folders on your Windows PC. Usually I map a network drive and type something like \\DESKTOP-******\Server. Now it doesn’t work. I also can’t access Remote Desktop. If I open a browser on another computer, it shows Windows Internet Services instead of the usual desktop. It looks like the connection is being blocked or redirected somewhere. Hopefully someone can help figure out why ports are being blocked or if there’s an issue with customer support. Thanks!
they didn't assist since they aren't permitted to help with topics outside specific sections. Or they simply can't. Do you have any additional outdated routers nearby? I understand your frustration. I also had 12 Mbps at my previous home, but now I have 500 Mbps.
The router can be set up as a bridge rather than a traditional router, meaning all your computers are linked directly to the Internet, which might explain why shared files aren't functioning. Connecting directly to the Internet is risky unless you're familiar with the process. Verify the IP addresses of your computers to ensure they match standard internal LAN ranges or public Internet addresses. For LAN addresses, the numbers typically fall into categories like 10.x.x.x, 172.x.x.x, or 192.x.x.x.
Are there any devices employing wireless technology? Yes, most routers offer an option to block WiFi devices, preventing them from joining network shares. It seems unlikely the problem lies with bridge mode. Also, it appears AT&T doesn't possess the necessary IP addresses for this functionality. I've heard that in certain areas of their network they're implementing carrier-grade NAT. Typically, most ISPs restrict to one IP address per customer unless you upgrade or qualify as a business client.
