Ender-3 V3 KE - how to setup mDNS on printer

[psielvis]

Hi There

Recently i had and update on wi-fi network in the office and some filtering was applied on wireless traffic.
Had a chat with local IT and they cannot whitelist printers IP in filtering as its some automated feature but also advised that normal printers work fine so its probably Ender setup which has to be updated.
I was advised to enable and set mDNS on Ender-3 V3 KE but honestly have no idea where it can be.
Tried to google it with no luck and have found 2 posts in which mDNS is mentioned but it doesn’t give me straight answer how it can be set.

Going Full Root on the KE, Getting Deep and Dirty!

Nice write-up. Even though I knew much of it, I learned something. A look at S01hostname was interesting. I changed my hostname to simply “ender” (all lower case) and now access the printer with mDNS as “ender.local”. Having upper-case characters in the hostname caused issues in the browser. ping always worked… I was not able to figure out how to set a static IP for wlan0. Has anybody else?

How to set static IP from root access from terminal for Ender v3 KE

Same problem here. It has nothing to do with the router. ifconfig wlan0 192.168.0.111 will set the IP address, but only until the next reboot. So, I resorted to relying on mDNS. Change the hostname to something all lower case (like “ender”) and then http://ender.local should work. It does for me.

I have followed some advice from there to change hostname on printer (after root) to simple lower case name but still cannot to printed via any slicer nor via web page

Anyone could help what needs to be changed on printer?
