This a laptop Toshiba Satellite s55-a5279, the newtwork is called freebox_QPOUCI, or any other router and even with public WIFI services. This problem began in february 2018, so I suspect is a buggy update, but I am not completely sure.

Ubuntu is installed in the HDD.

Try switching your router to channel 1 (use the router config page)

This may help

Mijail Febres Soria (mijaplex) said : #2

actionparsnip. Thank you for your answer, unfortunately I cannot keep changing channels in router everytime I leave home.

Do you take the router with you?

Mijail Febres Soria (mijaplex) said : #4

;) sorry, misspelled, I meant this problem is not only at home. I cannot go visiting friends/relatives or going out to libraries and keep asking them to change their channels.

You won't have to at their place. Do you get the issue with all networks?

Mijail Febres Soria (mijaplex) said : #6

Thank you again for taking the time.

Yes, I get this issue with all networks. I changed the channel to 1 in the router, I didn't help. I have this problem since February, I think it may be a buggy update, but I am not sure. I tried stuff I found in internet like:

 wifi.scan-rand-mac-address=no

and also:

echo "options iwlwifi 11n_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf
sudo modprobe -rfv iwldvm
sudo modprobe -rfv iwlwifi
sudo modprobe -v iwlwifi

It is like somehow the adapter goes off or gets uninstalled at random intervals and then like 10 seconds later turns on again. Maybe there some switch that puts the adapter to sleep? I am not sure how to test that.

I already reported it in Bug 1757561. It seems that no one else is suffering this problem with this version of Ubuntu.

Try:

echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9kfix.conf > /dev/null

Reboot to test

Mijail Febres Soria (mijaplex) said : #8

I tried:

echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9kfix.conf > /dev/null

The problem persists

OK then you can undo the change with:

sudo rm /etc/modprobe.d/ath9kfix.conf

Then reboot. You could try a newer kernel.

To try a new kernel I followed instructions from:

https://askubuntu.com/questions/119080/how-to-update-kernel-to-the-latest-mainline-version-without-any-distro-upgrade

and from http://kernel.ubuntu.com/~kernel-ppa/mainline/

I downloaded *.deb for amd64 in folder:

v4.17-rc1/

It didn't work, Do you think I can downgrade the kernel to a version from 2017? or is it risky?

Thank you in advance

Upgrade (from scratch) to Ubuntu 18.04 solved all issues.
