Hi,

 

I have the following setup:

 

• Teltonika TRB500 router with good connection on Mobile WAN, no issues, 180Mbs downlink
  • 192.168.2.1, DHCP active 192.168.2.1 --> 
  • Only connected device = Deco main unit, wired
     
• 3 x Deco M4 Mesh
  • 192.168.1.1
  • DHCP active, 192.168.1.100 --> 
  • Mesh = +2 Deco with wire
  • About 30-40 Wifi clients, 10 LAN clients
• Mostly ESP / Tuya / Other IoT devices
• Couple Xboxes, TV, computers etc.
• 5 x LAN cameras 

 

Problem

 

• Suddenly the Wifi dropped few clients out, like Xbox.
• My phone also dropped to "Not connected to Internet" but Wifi remained active.
• PC was really sluggish. Ping worked to 192.168.1.1 / 8.8.8.8 / www.google.com just fine, but any page couldn't be loaded with Chrome.
  • Speedtest worked 1/10, usually ended up "Network error" or download OK but upload failed.

​​​​

Troubleshooting

 

• Rebooted 4G router, no change
• Rebooted Deco via App, no change
• Moved DHCP away from Deco --> AP mode. No change

 

After 10 minutes everything went back to normal.

 

This has happened now maybe 5 times for the past couple of months. I'm pretty much the "not liked" person in my house, because can't get it fixed.

 

I have the logs on my computer (Deco / Teltonika), but wouldn't like to share them for public because possible data security issues. 

 

Some interesting lines from todays event, CRITICAL level:
