iwlwifi 0000:03:00.0: Microcode SW error detected. Restarting 0x20000

Hello Everyone,

I am having issues with my wifi connection. My wifi drops sometimes for no reason and I have to manually restart netctl-auto. Sometimes I have to do multiple times and sometimes I have to do only once. Then again it can drop at any time. Below is the logs from `dmesg`

I have seen many questions similar to this but I couldn't find any solid solution for this. I am posting this to see if there are any new answers related to this topic. Please let me know if you need any additional information.

I am using a Thinkpad x250.

Re: iwlwifi 0000:03:00.0: Microcode SW error detected. Restarting 0x20000

I had the same settings except for the `uapsd_disable`. I had the value `uapsd_disable=3`. I have changed it now and when I restarted, I still have the same logs from `dmesg` and wifi dropped couple of times and got connected automatically. I will have these settings for few more days and see how it goes. Thanks.

Re: iwlwifi 0000:03:00.0: Microcode SW error detected. Restarting 0x20000

Today when I try to use the laptop, laptop from sleep mode did't automatically connected to the wifi connection. I had to manually restart `netctl-auto`.
These are the logs before restarting manually.

`journalctl -u netctl-auto@wlp3s0`
