Hi all,

I recently bought an Omada setup but I am experiencing problems with my network connectivity. I found many forum posts with problems that look similar to mine. I have read them all and tried many suggested solutions, but for me it isn't solved yet.

I hope together we can pinpoint and solve the problems. Since I don't know exactly what causes it, I'll give you as much information as possible.

Network setup:

• ISP modem in bridge mode
• Asus RT-AC66U router with wifi disabled
• TP-link SG-108PEv2 switch
• OC200 cloud controller
• 2x EAP245v3 AP
• EAP225 outdoor AP

Furthermore:

• This system covers a household with one access point per floor. The amount of wireless devices is rather low (2 smartphones, 3 laptops, tv, chromecast, that's about it).
• All devices in the network are fully updated
• The wifi neighborhood is not very busy here. All my AP's typically show a utilization of less than 20%
• These problems never occured when I was using the router's build-in wifi, and also not over wired ethernet.

Problem description:
Regularly some devices in my network lose network connectivity, while claiming to still be connected to the wifi with full signal strength. This happens to multiple laptops and smartphones.

When this happens, the following is the case:

• The device can't ping anything but itself
• It still shows up in the clients list in the Omada controller
• Other devices which (according to the Omada controller) are connected to the same ssid, same frequency and same AP, keep on working without problems.
• Networking functionality is only restored after switching off and on the wifi, either from the device or from the AP

Turning all advanced features (fast roaming, airtime fairness, band steering...) off does improve the situation for some devices, but even then the problem still exists.

Who can help me to figure out the next step in solving this?
