Same here. Is there no help for this?

So in the original poster's post here they included lots of useful information. I think you should start by doing the same thing. Also include the output from lspci -nn | grep -iE "net|wire" to correctly identify the exact hardware in use. I would say that since the OP's output starts with
Jan 2 08:41:06 mapr04 kernel: iwlwifi 0000:3a:00.0: Microcode SW error detected. Restarting 0x2000000.
that points pretty much at the wireless firmware inside the wireless card crashing. You might look at the Intel website or ftp sites and see if you can find a newer firmware version that the one it reports itself as running 4 lines after that in the crash output.

You should also make sure that your system is fully up to date by running yum update. That will update the kernel and also the linux-firmware packages if they are not the most recent. I'd do this before you try anything else.
The future appears to be RHEL or Debian. I think I'm going Debian.

CentOS 5 and 6 are deadest, do not use them.

Also, be aware that CentOS 7 only has about 1 year of life left. You might also look at running 8 or 9 on it instead as those will both have much newer kernels with newer hardware support. I'd skip 8 and go straight to 9 as it seems better and more stable and doesn't have 'modules' for packages as much. Since there is no CentOS after 7, you'd need to pick one of Alma, Rocky, OEL or even RHEL itself.

You can get a free Red Hat Devleoper subscription from the Red Hat site and that allows you to run up to 16 copies of RHEL. The license lasts a year and then expires but you just need to revisit https://developers.redhat.com/ to re-activate it and then re-subscribe your system(s).
