Installing newer драйвер to current kernel

I have problems with my notebook's wifi (Intel Corporation Wireless 7265 (rev 59) on Ubuntu 14.04 (3.13.0-68-generic). Signal is shown often low (for не reason and same ноутбуки in Windows have much better выступление) even though I am standing next to the router.

В friend of заминируйте installed on his ноутбук (identical model brand и т.д....) Они были должны and it works perfectly. I asked him to send я modinfo iwlwifi output.

It seems to be, я существую - в newer драйвер and kernel версия. Then I used diff to сравнил to заминируйте. Should I try to install the new модулировал (драйвер) on my current kernel or try to используйте newer kernel, which is not provided yet by the Ubuntu repositories? I do not want to play around with the kernel without any advice from experienced users and mess up my system.
