Let’s go back to the previous century and care about IPv4 by ditching IPv6 support. If it doesn’t, check the other solutions. It should fix the slow wireless connection problem for you. Save it, close it, restart your computer. If you find this file, replace it with the following line: hosts: files dns In here, look for the following line: hosts: files mdns4_minimal dns mdns4 You can also use nano instead of gedit if you want to use the terminal. This will open the configuration file in gedit so that you could edit it easily in GUI.

Open a terminal and use the following command: sudo gedit /etc/nf To fix this bug, you have to edit the nsswitch configuration file. Ubuntu and many other Linux distribution are based on Debian so this bug propagates to these Linux distributions as well. The slow WiFi in Ubuntu problem could also be related to a bug in Avahi-daemon of Debian. Solution 3: Fix the bug in Debian Avahi-daemon Restart your computer and live your life at full speed. If you find no significant increase in the wireless connection speed, restart the computer to revert the changes and forget about this solution.īut, if it worked for you and you have a faster WiFi now, you should make the changes permanent by using these commands: sudo suĮcho 'options iwlwifi 11n_disable=1' > /etc/modprobe.d/nf It’s worth noting that in newer kernels, doing this will also disable the 802.11ac protocol and will limit the device throughput to 54 Mbps as mentioned in Gentoo’s wiki page. Open the terminal and use the following command: sudo rmmod iwlwifi It has been observed that disabling the 802.11 n helps speed up the wireless connection in Ubuntu and other OS. While 802.11n provides better data rate, not all the routers support it, especially the older ones. Even after so many years, most of the world runs 802.11a,b and g. The next trick is to force disable the 802.11n protocol. Solution 2: Disable 802.11n (works best if you have older router) If it does not fix or if you don’t have Atheros WiFi adaptor, try other solutions. Restart your computer and you should be good to go.

This will add the additional line to the configuration file. Here, you’re basically enabling a module to use software-based encryption over hardware encryption for your adapter. Open a terminal (Ctrl+Alt+T in Ubuntu) and use the following commands one by one: sudo suĮcho 'options ath9k nohwcrypt=1' > /etc/modprobe.d/nf

If your adapter manufacturer is Atheros, this solution should work for you.
