Hi!

Thank you so much for both of your notes. I really appreciate it. The question I started typing before I was banned again was regarding my internet connection. Ever since I converted my Dell from windows 10 to mint, my connectivity has been mediocre at best…tons of DNS errors. Daily. I actually revisited the post on the forum where you guided someone thru a similar issue who lost their ability to connect after installing proton VPN. I added two new DNS addresses, disabled IPV6 and voilà!

Thank you…and my telegram name is Moana. -)

I’m back. I have fully lost my ability to connect to the internet. Here is a screenshot after typing the command you recommended.

Just checking back. The conversion has rendered my laptop (my primary computer) useless since the conversion. Oddly it wasnt bad a first but slowly lost the ability to connect. Thanks in advance!

Hey @Moana,
Completely losing Internet is troubling. I have noticed that Proton has been having a few issues lately on Mint, having the IPv6leak active even when you disconnect. I have two recommendations for it:

1 - When booting up, check the network
First check to see if the IPV6leak is still running. You can do that via terminal when you execute:

ip link

If you see a connection named “ipv6leak”, you’ll need to delete it via:

sudo ip link delete ipv6leakintrf0

This is something I’ve been doing on my Mint installation quite a bit lately and described the issue here:

If you lose Internet connection under ProtonVPN

This may have happened to a few of us. Meanwhile, you will find some workarounds in these forums that will help you regain connectivity. Well, it’s time to get rid of the workarounds and address the issue head on with a solution that will work on all distros. First, to identify the problem. You are not losing internet connection. ProtonVPN initiates two different connections when you fire it up. One is the actual VPN tunnel, while the other is a leak protection for the IPv6. If you shutdown, su…

Also, on the DNS issue, you can open up your Network Connection in the Settings (for your current connection as in WiFi or ethernet) and put in the following settings (in red):

This will direct your system to resolve DNS via CloudFlare.

If general connectivity becomes an issue, then I’m suspecting it’s the old kernel (your Mint has the 5.4 version, while the latest one is 5.18). In that scenario, you can either upgrade the Kernel or - install the latest Kubuntu distribution, as I show below:

2 - Shift to a newer distro that has a much newer Kernel
In general, Kernels are the motherships that hold all the modules, AKA drivers, for the Operating System. For example, Kubuntu runs on the 5.15 Kernel, which has a huge number of extra hardware supported. It’s environment is also very Windows-like and much more configurable than Cinnamon.

Worst-case, if you enjoy the Cinnamon desktop environment, Linux Mint will update in a week or two with its Mint 21 that will also feature the 5.15 Kernel.

If you’re looking to test-out Kubuntu, you can pick up the ISO from here:
https://kubuntu.org/getkubuntu/

Please let me know what you are more comfortable doing.

By the way, I also looked you up on Telegram, but I noticed your profile is hidden. Alternatively, you can contact me there via my handle @vasileikon.

Good morning…thank you so much. I am trying all these solutions today and will report back. I am not married to mint so another distro is an option. My internet does eventually connect. It just takes like 15 mins and then constantly drops.

BTW I unblocked my profile on Tgram. Can you let me know if you can see it now?
Thanks again!
