Automatic identification of proxy configurations fails across all devices on the network.
Automatic identification of proxy configurations fails across all devices on the network.
Hello everyone, I'm facing some problems with my home network and would love some guidance. I've tried to share as much detail as possible, but if you have any questions, please let me know. All the devices on my network are suddenly showing this error: "Windows could not automatically detect this network's proxy settings." It seemed normal a couple of days ago, but after wiping my main computer and reinstalling the OS for unrelated reasons, everything started working again yesterday afternoon. This morning I woke up and it was all out of order—no changes overnight, and since I'm the only one here, no one else could have affected anything. No other computers on the network changed or disappeared.
* All machines run Windows 10 Pro (updates within the past week)
* Internet access remains intact
* Network shares are still visible directly but not listed in "Network Explorer"
* Three out of four computers are wired with two NICs connected. I attempted to join a bridge or team, but it caused a BSOD on all devices, so I deleted the bridges. Not sure if this is related)
* Every computer has manual IP addresses assigned via the router
* SMB1.0 is enabled because devices couldn't communicate otherwise
* After enabling all computers, they now see all shares correctly
* My home-built PC uses NORDVPN via a Windows app. The "Server" folder has the program installed but it can't connect to the VPN
* Pihole on Raspberry Pi was formatted and updated to version 5.0 yesterday and reconfigured, but seems to be working fine now
* Router: Asus RT-AC86U
* Switch: TP-Link Jetstream2 TL-SG3424
* Raspberry Pi 3: Pi-hole v5.0 | WIRED
* Home-built: 3900x | Asus X570-E | 32GB RAM | RX580 | Build 1909 | WIRED
* R720XD: Dual Xeon 2620 | 224GB RAM | Intel X540 network card | Build 2004 | WIRED
* Archive "Server": Athlon II x4 610e | Gigabyte GA-880GA | 8GB RAM | Build 1909 | WIRED
* Surface Pro 4: I7-6650U | 8GB RAM | Build 1909 | Wireless Network Config
I tried several fixes—reset network settings, checked drivers, used the Windows Troubleshooter, verified IP assignments, and even reconfigured Pihole—but nothing resolved the issue. Please let me know if you can help. Thanks!
