The internal wifi card works fine but sometimes, automatically gets switched off until I reboot the pc.

The rfkill list all doesn't show anything related to wifi so I think its not blocked

Code: Select all

0: hci0: Bluetooth
	Soft blocked: yes
	Hard blocked: no

I don't know what to do to fix the issue, if its a driver problem, then please tell me how to download and install the drivers.

NOTE- I an using an usb wifi adapter (TL-WN722N) to connect to internet.
NOTE2-I use mint in dual-boot with windows 10. Their is no issue with windows 10 as well as ubuntu 16.04 which I used previously in the same machine.

not restart but start. Try this instead.

Code: Select all

sudo service network-manager start

[greerd]

Soft blocked: yes
Hard blocked: no

Gleaned from one of JeremyB's posts, try

Code: Select all

sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/*

to disable power management.

EDIT: Might have to reboot after.

I tried but the problem remains.

And the lines you quoted, I think that shows the soft block for the Bluetooth (as I disable it )

sudo service network-manager start

Nothing happens if I type the code. Any other solution??

Try to install 4.4 lts kernel.

Only a link. I use 17.3 and it works there, but I see things have changed in 18.3, so maybe as others stated, you have driver problem, so give you this link.

viewtopic.php?t=226293

I suspect the driver being used is not the correct one, shown below. You should check what the device itself identifies as using lsusb command. Maybe then we can determine the correct driver for it. It may be you have to do similar as in the above link.

The problem is with the inbuilt wifi adapter not with the USB one(as I am using that to connect to the internet).

You use both wifi devices? This is the internal one.

Code: Select all

Card-1: Intel Wireless 7265 bus-ID: 04:00.0
           IF: N/A state: N/A mac: N/A

you said;

The internal wifi card works fine but sometimes, automatically gets switched off until I reboot the pc.

So, this doesn't even seem a wifi problem as much as a power control problem. Have you checked your power settings to see if some of them may be causing this? Just to check it out, make all power off timed settings be many hours, or turned off totally, see if the problem continues.

I saw on Utube that setting your router to only broadcast on one channel (static rather than dynamic) was a fix. I'm trying it now and it seems to have helped thou it's only been a couple days. NOTE: it helps to check on what channels other wifi networks in your area are using so you can select one that is possibly more "isolated"
