Deco X50 V1.0 – Mesh / “No Internet” Issue

Setup:

• 3 × Deco X50 V1.0 units, firmware 1.7.1 Build 25080612 Rel. 70421

• Ethernet backhaul between all units

• Network: 192.168.1.0/24

  • Gateway: 192.168.1.1 (Linux router)

  • DHCP/DNS server: 192.168.1.22 (Linux)

• All Deco units have static IP addresses:

  • PATRO – 192.168.1.20, MAC 7C-F1-7E-4F-CB-A4

  • VSTUP – 192.168.1.21, MAC 7C-F1-7E-4F-D3-0C

Observed behavior:

• When moving with a tablet or mobile device between mesh nodes, the device disconnects and either:

  • does not reconnect to the next node, or

  • reconnects but shows “Connected to device. Cannot provide Internet”.

• Sometimes the device stalls at “Obtaining IP address”.

• Signal strength for PATRO and VSTUP is acceptable (confirmed with WiFiman).

• Example: PATRO shows tablet connected with good signal, but the tablet has no internet access.

• Even when a static IP address is manually configured on the tablet, the same issue occurs, so it is not related to DHCP.

• The problem affects different devices (phones, tablets) in the same way.

• Ethernet connectivity is stable and reliable; the issue only affects Wi‑Fi mesh.

• Temporary workarounds: reset networking on the device, disconnect/reconnect manually, or forget and re‑enter Wi‑Fi password.

• Because of this behavior, Wi‑Fi mesh is practically unusable for mobile devices.

Log excerpts:

• Repeated errors: /usr/bin/apsd: wlan_get_links_qca:69: Error: ioctl

• stadbEntry_modifyTriggerThreshold shows RSSI ~41–44, RCPI -64 to -68.

• wlanifBSteerEventsHandleBeaconReport reports multiple BSSIDs with varying RCPI.

My question: Is this a known issue with Deco X50 mesh on firmware 1.7.1, and is there a recommended fix or configuration to prevent mobile devices from losing internet when switching between nodes?
