I am having the same problem since I upgraded. 5GHZ reaches 20megs on the 5ghz connection. Xfinity COMCAST came and did several tests but the culprit is my laptop as well as my wife's laptop. We need help in resolving this situation. Could it be the Linux Kernel version?

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 using 5ghz. 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
Let me know if it works for you!!
