Good evening, i am using a ubuntu 14.04 lts version on my laptop, whenever i connect to a wifi network, it disconnects automatically after 5-10 min, I have tried most of the posted solutions online as the prob seems common, however im a new user of ubuntu and do not have much experience with the terminal. I tried reinstalling the entire OS but the problem persists. my laptop config, is HP probook 440 g2, 4 gb ram, 500 gb hardrive, intel hd 5500 graphics processor ubuntu linux 14.04 LTS 64 bit system.

kindly help me out as the hardware support from hp has ruled out any defect in my wireless card and i do not wish to switch over to windows. my system shows wifi is working but it just would not connect again till i reboot the OS. NO supplied link so far has been able to fix this problem on a permanent basis. regards.

You can install a driver this way.

sudo add-apt-repository ppa:hanipouspilot/rtlwifi
sudo apt-get update
sudo apt-get install rtlwifi-new-dkms linux-firmware

it should work better after reboot.

  • @BhagirathTallapragada Please do not post extended outputs to comments. This looks OK. If there are no errors, then run all the rest commands and reboot. – Pilot6 Jul 07 '15 at 11:12

    @BhagirathTallapragada The problem was in a bad kernel driver. The driver you installed works better. It the answer was helpful, then you can accept it by clicking check sign at the left. – Pilot6 Jul 07 '15 at 18:11
