From b52a3124db2e5e41f9df77aa5459ccbd616af4cf Mon Sep 17 00:00:00 2001 From: Valent Turkovic Date: Sat, 3 Jan 2026 09:50:16 +0100 Subject: [PATCH] wifi-scripts: wdev.uc: fix mesh mode frequency handling Mesh mode interface creation fails when the freq parameter is empty or undefined. Unlike adhoc mode which checks if freq exists before using it, mesh mode blindly constructs the iw command with freq parameter, resulting in invalid syntax like: iw dev mesh0 mesh join ssid freq NOHT This causes the mesh interface to be created without joining the mesh network, leaving it in a DOWN state with no channel assigned. Fix by adding freq validation check similar to adhoc mode.
