Unable to connect to Mikrotik 5G after changing wifi card

jp flag

I have an ASUS TUF A17 (FA706IU) and my wifi card stopped working, I decided to replace it with another one and I changed it to Intel Wi-Fi 6E AX210 M.2 2.4Gbps 802.11ax Bluetooth 5.3 (AX210NGW). But now I'm unable to connect to 5G Mikrotik wifi. I'm saying Mikrotik here because I have an older router tp-link and I'm able to connect 2.4 & 5 GHz but only 2.4 GHz Mikrotik. For Windows 11 everything works fine so the card is able to do it, I guess something wrong with the drivers I tried to install driver from https://www.intel.com/content/www/us/en/support/articles/000005511/wireless.html but id didn't help. I'm using Ubuntu 22.04

upd: Tried echo "options iwlwifi 11n_disable=1 wd_disable=1" | sudo tee /etc/modprobe.d/iwlwifi.conf It helped to connect but the speed was awful.

upd: for some reasons speed dropped again, even when I removed password at allenter image description hereenter image description here

UPD: Well, I'm 99.99% sure that Mikrotik misconfigured, when I changed it to 20/40/80MHz Ceee from 20/40/80MHz XXXX it started working with encryption pretty fast. Hope it will be useful for somebody or somebody will advice something better! enter image description here

Fixed with changing wpa2 psk to wpa psk on Mikrotik side.

Upd: speed was awful, so I enabled encryption to normal wpa2 and changed Channel Width from 20/40/80MHz XXXX to 20/40/80MHz Ceee and now it works

Note that WPA is not secure. It can be cracked!

Yes, but at least now I know what to fix

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
