As per Wifi keeps on dropping in Ubuntu 12.04?, I followed the instructions: Copy it to your home folder and run sudo dpkg -i rtlwifi-new-dkms_0.5_all.deb . Having done that to 3.13.0-70, my connect speeds have dropped from 150 Mb/s to a max of 72 Mb/s and Internet speeds as well.

How do I uninstall the package? I did find out after the fact, that I have an Intel wireless card. Did not think Realtek driver would affect it as it has.

You can uninstall it by running

sudo dpkg -r rtlwifi-new-dkms

But if you have an Intel adapter, this package does not affect it in any way.

  • I was under that impression, but could not explain the drop in reported speed. I just used Synaptic to uninstall, but as you said, it should not affect. It is a Lenovo Z50 laptop.

Having gone through the network, the connect speed issue was network hardware and not Ubuntu 12.04. A WiFi a/p was at fault which cleared after a hard reset. Package was removed through Synaptic rather than command line.
