Hi! One of our subscriber keeps getting offline. Not sure why. We have clear line of sight to the AP and no power outage.
Here are the details:
AP:
Device Type : 5.7GHz MIMO OFDM - Access Point
Board Type : P13
Product Type : PMP 450i
Software Version : CANOPY 16.0.1.1 AP
Session Dump for LUID 3

Per ChatGPT:
- VCERR (Virtual Circuit Error): This error indicates that the data path between the AP and SM has failed. Common causes include:
- Interference
- Weak signal
- Hardware or antenna misalignment
- Network misconfiguration
- Flag 190 / 191:
- 190: Typically signifies that the SM lost communication with the AP, possibly due to RF noise, interference, or poor signal.
- 191: Often points to a more persistent or severe RF condition or internal timeout, which can also result from mismatched firmware or hardware faults.
I’m leaning towards hardware fault. But I’d like to know if anyone has any idea what could be the problem. Thank you!
