FAQ
TL;DR: After a reset, “DNS server isn’t responding” usually means 1 mis-set step: “No internet connection configured.” Log into 192.168.1.1, enter Orange PPPoE credentials, save, then verify Status. [Elektroda, Heinzek, post #17380259]
Why it matters: For Orange/Neostrada users seeing DNS errors after a router reset, this shows the real fix: reconfigure the WAN, not DNS.
Quick Facts
- Router admin panel: open http://192.168.1.1 to enter service login and password. [Elektroda, Heinzek, post #17380259]
- Orange/Neostrada uses a service login and password from your contract; enter them in PPPoE. [Elektroda, Heinzek, post #17380365]
- PC DNS changes (8.8.8.8/8.8.4.4) and flushdns won’t help without a working WAN session. [Elektroda, Willyff, post #17380225]
- To confirm the fix, check the router’s Status > WAN table and line status. [Elektroda, Heinzek, post #17380332]
- If your Polish firmware UI differs, configure the connection under PVC0 as advised. [Elektroda, Heinzek, post #17380442]
Why does Windows say “DNS server isn’t responding” after my Orange router reset?
Because the router lost its internet session during the reset. The system then mislabels it as a DNS issue. As one expert put it: “No internet connection configured.” Log into the router and re-enter your PPPoE service credentials. Save and verify the Status page shows a connection. [Elektroda, Heinzek, post #17380259]
Where do I enter my Orange/Neostrada login and password?
Open your router interface at 192.168.1.1. Go to the Internet/WAN section, choose PPPoE, and enter the service login and password from your Neostrada contract. Save changes. If you don’t have the credentials, check your agreement paperwork. [Elektroda, Heinzek, post #17380365]
How do I fix “DNS server isn’t responding” step-by-step on Orange DSL?
- Open http://192.168.1.1 and log in.
- Set WAN to PPPoE and enter your service login and password.
- Save, then open Status to confirm the connection is established.
This restores internet, resolving the DNS message. [Elektroda, Heinzek, post #17380365]
I set 8.8.8.8 and 8.8.4.4, but nothing changed. Why?
Changing DNS on your PC cannot replace a missing WAN session. If PPPoE isn’t authenticated, all DNS lookups fail at the source. The original poster tried 8.8.8.8/8.8.4.4 and flushdns, with no effect, until the router connection was configured. [Elektroda, Willyff, post #17380225]
How do I check if the router actually connected after saving?
Open the router’s Status page and inspect the WAN table. Look for connection state, assigned IP, and uptime. Support often asks for a screenshot of that view and the line status. If it shows disconnected, recheck your credentials. [Elektroda, Heinzek, post #17380332]
What is PVC0 and do I need to configure it?
PVC0 is the first WAN interface entry used by the ADSL firmware. On some Polish firmware, the layout differs, so update your connection on PVC0. As the expert noted: “Rewrite data for PVC0. Polish firmware has a different layout.” [Elektroda, Heinzek, post #17380442]
What if I saved the credentials but still get “DNS server isn’t responding”?
Suspect a wrong password or login formatting. Re-enter your service credentials carefully and save again. Then check the Status > WAN table for connection state. A reboot alone won’t fix incorrect credentials. The OP considered a password issue during troubleshooting. [Elektroda, Willyff, post #17380429]
Could this be a line problem instead of configuration?
Yes. If the ADSL modem isn’t synchronized, PPPoE cannot connect. Check the DSL sync light and line status in the router. If there’s no sync, contact your provider to resolve the line before re-testing. [Elektroda, jimasek, post #17380327]
What screenshots should I provide to get faster help?
Share the router’s Status page, focusing on the WAN table and the line status section. Helpers asked for that exact view to diagnose connection state and link status. It quickly reveals whether the session is configured and live. [Elektroda, Heinzek, post #17380332]
I can’t log in—what are the default router credentials?
If you haven’t changed them, try admin as the username and admin as the password. These defaults allowed the poster to access the interface after reset. Change defaults once you restore service. [Elektroda, Willyff, post #17380347]
Does disabling UPnP cause this “DNS server isn’t responding” error?
No. UPnP doesn’t control PPPoE authentication. The error arose because the router’s internet connection wasn’t configured after reset. Entering the service login and password resolved the issue. [Elektroda, Heinzek, post #17380365]
After configuring, should I reset the router again?
No. If Status shows connected, a reset isn’t needed. In the thread, resets and diagnostics didn’t help, while correcting the credentials did. Focus on accurate login and password, then verify on the Status page. [Elektroda, Willyff, post #17380429]
How will I know it’s fixed?
The router’s Status page will show a connected WAN session with an assigned IP. Browsing should work immediately without DNS errors. The original poster confirmed success after entering the correct connection settings. [Elektroda, Willyff, post #17380462]
