Mode Lan Disconected Frecuently

[recowass]

I’m experiencing a fairly annoying issue with my Anycubic Kobra S1 running Rinkhals (latest version 2.6.0.0).

The LAN mode disconnects quite frequently without any clear reason. After some time, the printer becomes unreachable over the network, and I have to go to the machine and re-enable the connection directly from the printer’s screen.

This happens consistently, not just occasionally. It interrupts my workflow because I lose remote access and can’t manage the printer until I reconnect it manually.

I’m not sure if this is a firmware issue, something related to LAN mode itself, or specific to version 2.6.0.0, but in my case it’s clearly unstable.

Has anyone else experienced this or found a workaround?

the same trouble with the s1 combo, I'm sitting watching the constant departures, by the way, where are you from, maybe the problem is with our service provider? ver 2,7.0.9

Without any debug logs, or other actionable evidence, there's nothing I can do about this issue. I'll leave this issue open until Apr 15th, and if there's no substantiating evidence or actionable error, I'll have to close it out as an incomplete issue report.
