After 15.6 version upgrade, my internet's speed is capped at 20mbps with the 5ghz connection. My wife's laptop has Elementary OS and she can reach speeds of 150mbps on the 5ghz connection. My stepson's laptop has Windows 10 and he as well can connect to speeds of 150mbps with the 5ghz connection. My Android phone can also reach speeds of 150mbps with the 5ghz connection. I am assuming that it is the new 15.6 version and not the Linux kernel version. I saw another user post the same issue. Help us please!
Was the Network Manager updated for 15.6??
JUST TO BE CLEAR, the wifi card works but it is not reaching the speed intended speed that I had before. I was connected to 150mbps. Not anymore. Here is my wifi card information.
$ lshw -C network

WIRED CONNECTION reaches 176.8mbps, so something broke in the new version broke the wifi speed and it is capped!
UPDATE!!!
I found a website that someone else was having a similar problem and decided to give it a try. Guess what? It worked! My wifi is now reaching the top intended speed that I am paying for. The command in the terminal was echo "options iwlwifi 11n_disable=8" | sudo tee -a /etc/modprobe.d/iwlwifi.conf
Afterwards, reboot and hopefully it will work for you! The site where I found the solution was at https://ubuntuforums.org/showthread.php?t=2246457&p=13133995#post13133995
I purchased a new wifi card to receive 5ghz and deleted the 11n_disable=8 line. Why? Because even with 5GHZ speed it was still giving a top speed of 25mbps when I should have had over 150mbps.
