Wifi won´t work after update - firewall problem (SOLVED)
« on: January 28, 2020, 08:06:03 am »
After a update a few weeks ago - including a kernel-update - the following strange thing occurs. The wifi-connection is established. But no page will load; nor can I get updates. When I switch the firewall on and off a few times, the connection becomes normal and pages load. I have made no changes at all before this; the firewall was even switched off.
Looking around on the forum I´ve seen a possible solution is to remove advert blocker and delete hosts-file in /etc. There are the following files: hosts, hosts.allow and hosts.deny. Should I remove them all?
Booting a previous kernel did not solve the problem; nor changing the IPv6 settings.
Here are the requested outputs, made before establishing the connection:

What kind of problem lead to kernel update? Maybe you don't need it. If it happened automatically, at the start you can choose an earlier kernel version. If it does the trick, you can stick to that kernel version, no need to go ahead.

The update was automatically. As mentioned in my first post, booting a earlier kernel did not work. I booted ¨back¨ till 5.0.0.36.

Sorry for misreading.

My hosts file after clean install (in VirtualBox) contains:

Spoiler (click here to view / hide)
127.0.0.1   localhost
127.0.1.1   username-machinename

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
[close]

Nothing else. IMHO it worth a try to switch off the advert blocker and delete the rest lines. They will be populated again when you switch it on again. Don't forget to make backup, say,  hosts.ORIG !

The hosts-file is the same:

127.0.0.1   localhost
127.0.1.1   mefibo-HP-Stream-Notebook-PC-11

# The following lines are desirable for IPv6 capable hosts

fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
[close]

Removing Advert-Blocker did not solve the problem, unfortunately.

Generally, at startup the firewall is inactive; when I switch to active the connection is established. Is there a way to activate the firewall automatically while booting?

Hi mefibo, I don't use a firewall so not sure how much help this might be, have you tried right clicking on Firewall configuration and clicking on Options  Use startup notification?   :-\
What was I thinking?

Hi alynur, unfortunately that did not help. I´ve removed the firewall from the system then I don´t have a connection at all. Re-installed it with a usb-stick. Nothing changed, but I can connect by switching to active.

Hi, do you mean that without an active firewall it is all OK? Am I right? If not, maybe this helps: one of my computers is an old ASUS K50IJ Notebook and this one cannot connect to WiFi above 4.18.0-21 kernel, so I had to stick to that version.
Another test: if you try to run a live media with a clean PepperMint Ten, does it works or not?

Hi, Just the opposite; with no firewall I can´t get a working connection. Hence I had to reinstall via usb-stick. I have to change the firewall settings from off to on to establish a working WiFi-connection. I´ve booted several previous kernels; did not work. I have not tried a fresh Peppermint 10 yet due to specific hardware-problems handled in ¨New Users¨. But I will try a new Live USB one of these days.
For what it´s worth; I was at the 5.0.0.x kernel. The problem manifested after a update to the 5.3.0.xx. But however; when I boot a previous kernel now it does not solve the problem.

Hi, for your curiosity I´ve tried the 4.18.0.25 kernel; the...21 kernel is not available on my system. Did not work. So I think it´s save to say the kernel version is not the problem. What is, I have really no idea. I hope someone has.

uname -a gives:

Code: [Select]

OK I guess it but the last chance is to try a clean live media. If it prevail then you can
trace the problem by comparing suspicious files both your os / live os
make a clean install - reinstall and do not forget to make some kinda of saves before any upgrading - fsarchiver, timehift and so on.

I have tried the latest P10 Live distro; everything works. The wifi-connection as well as bluetooth (I had specific problems with that).
So I would like to try upgrading from P9 to P10 rather than perform a clean install of P10 in order to save installed programs and my wifi printer. Is that possible?

Sorry, but that's not possible.  You must do a full install.
