I am running a dualboot setup on my Lenovo Flex2 with Windows 10 and Ubuntu 15.10. I am on the rtlwifi - rtl8723be wireless card. While my wifi disconnect issue has been resolved, I have found out that my wifi speed is 3 times less than what I get on Windows 10.
I have a 15 Mbps broadband connection. I consistently get the same speed of 15 mbps on windows but a maximum of 5 Mbps on Ubuntu. On my Android phone I get around 12 to 13.5 Mbps.
I am on channel 6 (2437MHz) of the wifi router with AES encryption .Router is Tenda_3623D8. Current connection of my Ubuntu machine is on the 40M bandwidth as per the router status page.
Any idea how to reach a better speed on Ubuntu?
