(SOLVED) Massive internet problems since update to LM 18.1

Post by gfl » Sun Feb 26, 2017 1:13 am

Good morning

I have been a satisfied LM user for several years now and although I'm not an expert, I have always found a way to solve the odd issue with my system. But I'm not sure about this time around:

Recently I have updated from 17.3 to 18.1 on two of my computers. On both of them internet use (Wifi) has become a real nuisance. Not always, but much too often, when I try to open a website I get a DNS_PROBE_FINISHED_BAD_CONFIG error. After 2-5 reloads the page would eventually open. This is extremely annoying, especially if you are in the process of booking a flight ticket or similar, because it would interrupt the process several times. Now this is probably very unspecific. What I can add is the following:
  • The internet connection per se is fine and so is the Wifi. I have now installed Solus Linux on my wife's computer and the internet works just great. The same internet connection works also fine on my iPhone and Android tablet.
  • The problems do not depend on the browser on LM. I have the same issues with Firefox, Chromium and Chrome. So changing some of the settings on the browsers, as recommended in other threads, did not help.
  • It's not only affecting the browsers. Updating through the Update Manager has become a real nightmare. Most of the time I get something like: W: Failed to fetch http://packages.linuxmint.com/pool/main/m/mintupdate/mintupdate_5.2.1_all.deb Temporary failure resolving 'packages.linuxmint.com'. Only after several re-runs the updates are finally found and installed.
What could have caused these problems after the update to 18.1? And how can I fix this?
Thank you so much in advance for any hints!

Have a great Sunday,
gfl

Try install this :

Code: Select all

sudo apt-get install linux-firmware
(you will need a Lan /hard connection temporarily)
reboot it should work.

Now it seems that the problems persist mostly with Google Chrome.
Firefox runs much better, also I was able to use the Update Manager.
That's better but not perfect, since I prefer Chrome since it synchronizes so much better with my Google account.
When is LM 18.2 due??? Maybe it will solve this issue.

Can you change the encryption on the wifi router to WPA2 only? I see it is using TKIP

Thanks.

So what I could do was:
  • Authentication mode: WPA/WPA2 (unchanged)
  • Encryption mode: AES (instead of TKIP&AES)
No great success so far.

When is LM 18.2 coming out? :-)

In about 3 months according to what I've read.

You could try

Code: Select all

echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf

Code: Select all

sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
Reboot

Thanks. No idea what I did here, but I did it...

I will let you know whether this solved my problem or not.

If not, I'll wait for Linux 18.2 instead...

Cheers,

The first command affects hardware encryption and has worked on some troublesome situations. The second command prevents network manager from trying to enable power management on wifi...it shouldn't be a problem with the ath9k driver being used as it blocks power management changes but you never know if it might cause a conflict

Re: (SOLVED) Massive internet problems since update to LM 18.1

Post by massasauga » Wed Mar 22, 2017 8:30 pm

I have a triple boot setup:
Windows 10, Linux Mint 13, and Linux Mint 18.
Windows and Linux Mint 13 connect to the internet over ethernet normally (so I know my hardware is OK).
Linux Mint 18 started screwing up with connecting to the internet after the second to the last update (I think). I can still connect to my router and my wireless printer, but I can't get past the LAN.

I came up with two workarounds for this. Neither one is perfect, but they seem to work in a pinch (until the connection to ethernet is fixed).

1. Boot up into Linux Mint 18 as usual.
2. Restart your DSL modem. This takes about 2 minutes with the DSL modem I have. Of course, this isn't too good for anyone else using the LAN.
I can usually get onto the internet once this is done.

Another possible workaround to this problem if you are using a router is to put your DSL modem into bridge mode. This makes your router make the internet over ethernet connection instead of your computer. You may have to set your router up to pass your user name and password to your ISP, and you may have to restart your router or log onto your router and force a test connection, but this will probably be a little quicker than restarting a DSL modem.

One other possibility is to scrounge up a WiFi card and install it. I have heard that Linux Mint 18 is still connecting over WiFi.

Good luck, have fun, and let me know how any of these workarounds work, or if you find out something new.
