Alright Nurah, this one is a classic Alcatel / ALE Wi-Fi band-steering issue , and the log actually tells us exactly what’s happening 👍 Let’s break it down calmly and then I’ll guide you to fix it properly. 🔎 What the log means (plain English) Log message (key part): [dcm] auth: Client 78:4b:87:e8:5f:82 tries to connect 2.4G radio, the vap is ath001, disallowed by DCM, Deny by 5Ghz Band Steering Enforcement Option. Translation: A client device (MAC: 78:4b:87:e8:5f:82 ) Is trying to connect to 2.4 GHz On VAP ath001 (your SSID radio interface) But DCM (Dynamic Client Management) says ❌ NO Because Band Steering is forcing the client to use 5 GHz So this is NOT an authentication failure, password issue, or encryption problem. 👉 It is intentional rejection by the controller . 🧠 Why this happens Band Steering is enabled, and ALE’s logic is: “This client looks capable of 5 GHz → don’t let it sit on 2.4 GHz.” This commonly happens when: Device supports dual-band RSSI is “good enough”...
