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?

  • See if wifi module has power saving feature. You might consider disabling it if it exists – Sergiy Kolodyazhnyy Feb 27 '16 at 18:16
  • On side note: One should do apples to apples comparison...comparing your laptop/desktop with Smart phone(even based on Android) is not a good idea...my smart phone has always better performance than laptop/desktop for the same wifi. – Ashu Feb 27 '16 at 18:50
  • @Ashu, i dont think that is entirely true. the download speed should not vary too much between devices. having said that I have already compared windows vs ubuntu on the same laptop – Ubuntuser Feb 27 '16 at 19:35
