I did what stated here https://unix.stackexchange.com/questions/397370/wireless-network-slow-speed-inconsistant-connection-intel-dual-band-wireless as the solution and seem to be now working fine. Not 100%. But far better than before. I got the error message only like couple of times today!
That is a pretty standard solution. That’s why I gave him the driver options earlier in the thread. You should not just post links, as they can go down. Post a summary of the pertinent info as well:
/etc/modprobe.d/iwlwifi.conf with the following options:
options iwlwifi 11n_disable=8 options iwlwifi bt_coex_active=0 options iwlwifi swcrypto=1
It will enable antenna aggregation ,disable Bluetooth coexistence and enable software encryption.
You might want to try substituting “1” for “8” and see if that works better. As so:
options iwlwifi 11n_disable=1
Thank you. Great explanation.
