The problem has gotten worse, I'm unable to use my wifi because it disconnects every 1-2 mins. It happens mostly after resuming from sleep. The workaround script helps only for another 1-3 mins.

Sometimes after 1h of using my laptop, and sometimes after resuming from sleep. It can't work again until I reboot my laptop. The most relevant error message is: sty 25 14:42:13 leetbook kernel: iwlwifi 0000:25:00.0: Failed to wake NIC for hcmd sty 25 14:42:13 leetbook kernel: iwlwifi 0000:25:00.0: Error sending STATISTICS_CMD: enqueue_hcmd failed: -5 I'm using Ubuntu 20.04 that was upgraded from 18.04 and earlier 16.04. I've searched for similar bugs, but it looks like my error message and card model is a bit different. The workaround script from bug 1673344 works to fix the wifi without rebooting. The card works fine in Windows 10 so it's not a hardware issue. This is not a stock card from HP EliteBook 8470w, I've replaced it to gain Wifi 802.11ac transfer speeds.
