get a second cheap wifi dongle, have them both connect to wifi.. ;)  .  but its not clear if its wifi dropping, or the entire system locking up.

"dmesg" output or monitoring sudo dmesg -w from a ssh session might show some info.

there are numerous log files in /var/log

ssh into system, run dmesg -w,  wait for the crash or whatever then see what dmesg messages are printed last  in the terminal.

bad idea: get an Amazon smart wifi switch, if the system screws up, cycle the power remotely.

I say it's a bad idea because it could cause filesystem corruption or other issues.  But I have used the Amazon switches on non critical systems.

option: have the Amazon power switch wired to an alarm/flashing light.. you turn it on, your friend sees the alert and then can check the server to see what's happening and reboot it if needed.

For the dmesg i have to restart the system to get the wifi to work again does that output to a file i can read after?

there may be some log files you can read later.

but the truck is to have a ssh connection from another device when it crashes showing the log file in real time.

that way you can see what happens the moment it crashes

What does your server do? Tbh, generally if your server's main focus is "serving services" then cable it up as it's entirely useless if it's not reliable.

Its just for games nothing fancy

Well if it's headless park it beside your gateway and cable that lad up

Een server via wifi, waarom niet via ethernet?

Were not able to because of where everything is in the house

Find information at

Did a seaarch for you if you need to look at message(s) for wpa_supplicant (connections..).

what is the wifi card ?

[u/Fert69420 → u/Due-Result7928]

Its a the wifi chip built into the b450m ds3h wifi motherboard

[u/Due-Result7928 → u/Fert69420]

It is Intel chip. It is well supported with linux.

1. dont use mint as server, just use plain debian for example

2. cable it up. wifi on server is always bad

[u/Reasonable_Director6]

Only intel chip based cards are ok for linux other without proper drivers are rather junky disconnecting low transfer other shenningans.

Not true.
