lately I've got problems with my wifi (Intel 7265). Internet connection is getting off every couple of minutes. Here is dmesg:

Can someone please tell me what is the problem?

Your wireless card is dropping to roam to a different access point. You can see in dmesg that it leaves 84:a4:23:61:56:30 to connect to 84:a4:23:61:56:31. I suspect that these are the 2.4 gHz and 5 gHz channels of your router.
I suggest that you try binding Network Manager to one or the other like this: Ubuntu connect drops. Worked for a while then started dropping again
If this is ineffective, rename the SSIDs to something like router2.4 and router5. Connect to one and stick to it.
