Hey

There a few things we would need to know before we can help you.  On the 225 outdoors are you connected via 2.4ghz or 5ghz?   Is this different to the router direct?

Also have you tried changing the channel on the AP? 

Its unlikely a device hardware issue, usually that would stop working completely and not slow speeds.

...

PS.   In response to your question

access point/router with good signal even behind wall, wide coverage, and stability for gaming

Honestly... WiFi signal is WiFi signal and regardless how what AP you use a wall will have a very negative impact on it.  Speaking from experience, generally different vendors / models / specs  are really the same in terms of signal, its just a limitation of the airspace.   

There is always going to be a balance between speed vs coverage, wiring in the APs and mutiple APs all controlled by a controller is your best option.  Something like the OC200 would work with your 225 Outdoors

Thanks for the reply. To answer your questions:

On the 225 outdoors are you connected via 2.4ghz or 5ghz? 

Yes, and both are experiencing the same issue.

Also have you tried changing the channel on the AP?

I haven't tried it, do you have the recommended channels for me to test? I just tried playing with the transmission power for both 5 and 2.4ghz to know if this is an interference problem, but unfortunately no luck.

Something like the OC200 would work with your 225 Outdoors. 

Actually, I looked into purchasing one but I only have a single EAP225 (I thought it was an overkill for my simple home setup). But, I did tried the Omada's offering of cloud-based controller. I was facing a lot of issue like the AP is disconnecting, problems with the IP renewal etc. So I did not proceed in purchasing a paid license.

As of this writing, The EAP225 seems gone haywire, I could connect sometimes to it but I couldn't manage it as a standalone AP on the Omada App. :(

Edit: Even if I could connect, it will do its thing again:

2nd Edit: Posting some of the EAP225s info:

Hey

Looking at your reply and screenshots there is little to be concerned about there, it looks to be setup fine..   so its not a config that i can see

However what firmware are you running on the AP?   5.0.6 by any chance?   Some users have started to report issues with 5.0.6 and downgrading to 5.0.5 appears to fix this..   sympotoms are not totally un-similiar to yours.  

I would try updating / downgrading to 5.0.5 firmware and see what happens then.   That would be the first good point of call

In terms of a OC200, its not required for a single AP no and really wont offer any advantage unless you are going to consider a seconed AP at some time

AH the old cable issue, that has caught me out SO many times!!  

Glad you got sorted all the same  :)
