Clients connections keep dropping
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I'm experiencing frequent loss of connection between clients and the wireless access points. On many occasions, a tablet or phone that is unused for an hour (or less) when trying to access internet via web browser (or email app) for instance will not load the screen and finally "no internet" even though the wifi connection shows as connected to the ssid. I have to manually turn wifi on the client devices off then back on again to access internet.
It's a simple (overkill) network with 3 EAP 245's in a large home on an Edgelite router. I've optimized network as much as I can tell (I'm just an old retired guy, not a techie, but I try hard). Different non-overlapping bands (20 Mhz on the 2.4) and on the 5 Ghz, Cat 6 backhaul with no mesh, most of the time only 8 to maybe 12 clients connected, cable internet speedtesting around 105-150 mbps, Omada controller running on a intel i7 machine with plenty of ram and fast ssd's, and I've tried to look at and understand different settings plus used simple wifi analyzer programs that seem to indicate little to NO interference on any band. Nothing ever seems to drop out or lose connection when using devices---only when sit idle for period of time. Never happened with old (Netgear Nighthawk) wifi network or on other networks away from home.
When it works, it's fantastic but frustrating when the wife keeps telling me her phone doesn't have internet (or her tablet). Any suggestions appreciated! There has to be a setting somewhere that I'm missing?
Thanks,

That is an interesting issue. I have sites with hundreds of clients on a controller, and I have not run into it. Some things I'd recommend looking at:
1. How are the clients spread out across your APs and bands? Are you getting 50+ clients on one AP or one channel? That's a recipe for problems
2. Check the data rates! Look at the connection speed in the controller. This has given me a lot of good insight when I'm debugging. Look for devices with unusually low speeds, and see if any devices are linking at 0Mbps.
3. Find some way to link the problem devices together. You say your Mac users are having issues, and in my experiance, that usually means you are having issues specifically with 5GHz, which Macs don't like to roam from as easily as other devices. See if you can find anything similar between the devices.
Now assuming that the controller is actually causing the problem, some other questions I'd ask are:
1. How is your controller set up? Did you get a OC200, or are you running Omada on some other hardware? If it is a custom setup, is on on Linux or Windows?
2. Have you checked the controller system to make sure it has plenty of space avalible, etc?
3. Is there anything relevent in the controller logs?
I know, that's quite a list... Hopefully, it's actually helpful instead of annoying! 
Good Luck!
