Ok, so as I said in my previous comment, I have tested the performance
of wifi in Ubuntu 14.04 in 3-4 laptops in last 1 week.
After fresh installation, wifi keeps on dropping. Then I applied tlue's
workaround on all of them which was:
echo options rtl8723be fwlps=N ips=N | sudo tee /etc/modprobe.d/rtl8723be.conf
Now after doing this, the wifi stabilizes but after long usage (2-4
hours continuously) it drops for 5-20 seconds and then either comes
back automatically or needs a reconnect (Reboot is not required to
reconnect in this case).
So after digging about incompatibility related to msi in rtl8723be, I added one
extra parameter in above command:
echo options rtl8723be fwlps=N ips=N msi=1 | sudo tee
/etc/modprobe.d/rtl8723be.conf
After using for 4-5 hours I didn't see a drop. Still I am keeping
fingers crossed.
