I have a brand new Hp 15 r215nt notebook. I have just installed 14.04 LTS. I noticed that wireless connection drops after sometime and needs a startup. (Disconnect/Connect wifi doesn't help) If I connect powercord I don't have this problem. Is there any solution?

Run this command and reboot:

echo "options rtl8723be fwlps=N ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf

If Power Management is on, your wifi card will stop working after some time to save power especially when power cord not plugged in. So check whether Power Management is on using iwconfig

for restarting wifi use sudo service network-manager restart
