Hello! I am a new user of Linux, and I decided to start by installing Mint Cinnamon on a Dell Inspiron N5110 on Monday. It worked fine then, but when I booted up the laptop on Tuesday, I couldn't download anything over the internet (not web pages, updates, software, anything). I checked my internet connection, and it said it had a strong connection both with Ethernet and on WiFi. I tried using TimeShift to go back to Monday, but it didn't work. I tried searching these forums and the internet, and while I saw several people who had similar issues to me, I couldn't get any of their solutions to work either. Is there anything I can do to fix this without having to wipe the system and reinstall Mint from scratch?

Re: Internet won't work despite being "connected"
Go into Network Manager -> Network Settings then select your wifi connection. Click on the gear then select IPv6 and turn it off (slider at top). Also, turn off any VPN you might be using. Reboot and test wifi.

Re: Internet won't work despite being "connected"
I may be jumping the gun here, but have your tried using the ping command to ping the site's IP address instead of pinging FQDN (Fully Qualified Domain Name).
For instance, I happen to have the IP address for kadaza.com. It is 45.79.79.74
So you use the bash terminal and type 'ping 45.79.79.74' without the single quotes. See if you get a response.
If you receive a response, then try this 'ping kadaza.com' If you don't receive a response, then it is probably a DNS issue.
I usually assign my DNS server manual to either of these:
8.8.8.8
8.8.4.4.
1.1.1.1
If you try to edit the /etc/resolv.conf file, it won't last. There is a way to do it using the GUI for Network Manager.
Sometimes, this is an issue that can persuade an experienced network admin to remove some of his/her remaining hair.
Another thing you can do is to boot the install medium (USB or DVD) and when Mint appears, try the same thing. If it works from the install media, then it is definitely an issue with the DNS on your installation of Mint.
Too bad you don't live close by...I'd be happy to have you bring your computer over and work on it at my house.
One other question has to do with the connection between the computer and the router. Do you use a wired connection or a wi/fi connection?
Best of luck.

Re: Internet won't work despite being "connected"
I tried both methods you suggested, and they both seemed to indicate that this is a DNS issue, thank you so much! In order to fix it, would you suggest going in to manually fix the DNS, or just reinstalling the OS from scratch? I've only had this system running for a few days, so I wouldn't be losing anything important.
I typically use a mixture of wired ethernet and WiFi depending on what's most convenient at the time, I'd been testing both on the original system and neither worked, though both worked when booting on the install medium.

Re: Internet won't work despite being "connected"
My recommendation is to fix it on your machine.
There are at least 2 ways to do this; one is very easy and the other is easy also, but depends on your comfort editing a file.
At this point, let's try the 2nd method.
1 open a terminal window and become root with the 'sudo su' command
2. then type 'xed' in the terminal.
3. Xedit will open. Using the open file command, open /etc/NetworkManager/system-connections
4. You will need to know the name of the connection. Once you find that, you may want to save a backup copy of the file.
5. Edit the connection. Put the lines in it:
[ipv4]
dns=8.8.8.8;8.8.4.4;
dns-search=
method=manual
6. save and close the file.
7. restart your network to see if it works.
You can also use the NM GUI (Network Manager GUI) to do the same thing. Some people find this easier to do.
1. Open the Network Manger GUI. You can find it in the applications menu (listed as Network)
2. In the window, you should see a list of your network connections. Click on one of them, then click on the icon that looks like a gear. In the new window, click IPv4. Disable the DNS automatic section by clicking on the Automatic arrow so it become unchecked. In the DNS Server box, insert the following IP address numbers: 8.8.8.8
3. Restart your network connection and see if that works.
