moshe@moshe-ThinkPad-T420:~$ lsmod|grep iwl
iwldvm 233472 0

iwlwifi 311296 1 iwldvm
cfg80211 679936 3 iwldvm,iwlwifi,mac80211

Laptop Lenovo T420
Linux Mint 19.1 Mate
Any ideas?

Code:

dmesg | tail

Should have some info when wifi drops out before logging out and logging back in to get wifi.

Edit: Was md5sum done to check iso file integrity before installing to usb before installing mint?

I found another sort of solution if you could call it that, to turn off the router wait and two minutes and turn it on again.

I don't remember doing mdm sum before installing.
This is something that started to occur about 6 weeks ago, otherwise it worked OK. Do you need anymore info?

Reseting router is a Internet Service Provider problem on their server end hooking up to your place of residence.

That is problem outside of operating system territory.
Md5sum explained in laymen terms.

Also. Try and use the advanced reply option < go advanced button underneath > and use the # symbol to bring up code tags so you can insert terminal readouts to show like so. Like your dmesg output.

Code:

harry@biker:~
$ inxi -G
Graphics:
  Device-1: Intel 3rd Gen Core processor Graphics driver: i915 v: kernel 
  Display: server: X.Org 1.19.2 driver: modesetting unloaded: fbdev,vesa 
  resolution: 1366x768~60Hz 
  OpenGL: renderer: Mesa DRI Intel Ivybridge Mobile v: 3.3 Mesa 13.0.6

I see nothing in dmesg that leaps out as a root cause but my skill set is not perfect Yet, when it comes to reading code outputs.

So far. It seems you might have started a thread over Internet Service Provider problems.
Something I live with on a daily basis. Which is outside of my laptops, desktops, and smart tv control.

Edit: found this though

Quote:

Your "wlan0: deauthenticated from 00:13:10:ee:af:97 (Reason: 7)" log message probably came as a result of your client receiving a DeAuthenticate (or DisAssociate) management frame from the AP. It seems as if the AP is allowing your client to Authenticate and Associate, and then a moment later, when the client starts sending real data traffic ("Class 3 frames"), the AP acts as if the client wasn't associated, and kicks it off the network (deauthenticates it).

Was there anything that occurred at that time that may cause this, even if it may seem unrelated to the problem? Maybe a router firmware update?

As someone has asked me about the Router Not known to me, I've not updated the Router Hardware. I'll contact the Internet supplier and see what they come up with. One thing I've also found that sometimes I've had to move from the 4G connection to the 2.4 Wirele:ss connection. The router is only 3 meters from my laptop.

I believe it's a bug in Linux Mint 19.1 with the Bluetooth, and it's recommended to disable Bluetooth.
