Home wifi network not searching web using Ubuntu












0















Problem: Lost my wifi connection after using HP Laptop running uBuntu 18.04 in a public place. My wifi symbol was gone when I got home. When I click on System Task Bar it says wifi is not connected. I then click on connect wifi, and then choose my home network and it asks for authentication. My wifi signal then appears and Ubuntu shows that I am connected to my network. I am using Firefox as my web browser.. When I try to go anywhere on the web I get a "Hmmm we can't find that website" no matter what it is. I have another laptop, a DELL Latitude running Win 7 and it connects to my home network with no problem. Also, now when I return to this restaurant with either laptop it connects to their wifi with no problem.



Did I get hacked at the public wifi? What do I have to do to get my wifi working again? Anyone have any suggestions? Is this a Mozilla problem as I use that on both laptops but the one running Ubuntu is giving problem.

  • What does nslookup askubuntu.com tell you about nameserver that it's using ? If you suspended the laptop after using the laptop after using it on public wifi it is quite possible that it is still using the old nameserver to resolve websites ( i.e., find what IP address belongs to a website )

  • Try the same command nslookup in your other Windows 7 laptop and compare the nameservers that the two machines are using

My idea is that there is kind of proxy installed. Things to be checked are Wi-Fi and Network in Settings. On the other hand, contrary to other browsers, Firefox may use its own Connection Settings (in preferences - Network Settings). There are 4 possible choices: No proxy, Auto-detect, system proxy and manual proxy. At last, and it worked for me, you can remove firewall in terminal (Ctrl+Alt+T) with sudo ufw disable.
