Hi @Melvinp 

Thanks for posting in our business forum.

Do you examine your direct connection from the ISP?

I don't think replacing a router would yield a difference. The loss of your packet is factual as far as I think.

Hi @Clive_A, i've tried to unplug my cable from ONT and do a ping test directly to ONT, everything works fine. but once i re-plug the cable back to the switch, it will started timed-out. i've contact my ISP provider and everything works fine at their end.

 

 

 

Ping result when you connect directly to the ISP modem-router. Use ping -t and the result screenshot.

WAN information while the Omada router is connected to the modem-router.

PC directly connected to the router LAN port. Run the ping directly from the computer. Result.

What's your LAN subnet? LAN config.

This is the second time you reported such an issue. What happened last time? How did you resolve it last time or was it never resolved?

Network Broadcast IP : 192.168.0.255

Network IP Count : 254

Network IP Range : 192.168.0.1 - 192.168.0.254

Network Subnet Mask : 255.255.255.0

 

Nothing solve on the first time when i posted it, i just leave it be but right now, its getting more worst.

But some information I require is still missing.

This looks really bad as far as I can see. Your line is not stable. It is through, but not stable enough. I cannot judge based on the given information.

Preliminary conclusion is WAN is not stable.
