Model: EAP225  
Hardware Version: V3
Firmware Version: 5.0.5 Build 20210604 Rel. 51118

Hi,

My device is not connecting to the nearby access point. It persistently connects to a device of the same brand but different version. 

 

 

Thank you for your help.

Hey

 

I am guessing you are not running a controller to manage the EAP225s?   However if you are, do you have Roaming or AI Roaming enabled?

 

I have seen this before with a printer..  Guessing the device is 2.4ghz?

 

Short answer is I had a printer that was constantly connecting to the wrong AP, it always connected to the furthest away.  After much head scratching I worked out that the printer was scanning the airspace for known SSIDs in asscending channel order.. namely it started at Channel 1 and worked up to 11 stopping when it found an SSID it liked.  Turned out channel 1 AP was the furthest away, when I powered the AP off it went to channel 6 the correct AP.

 

I had to manually set channels on the APs so the one nearest the printer was channel 1 (it was previously 6) and its connected first time to the right AP each time.

 

Hopefully same for you?   Roaming and AI Roaming will help with this if you have a controller is place.

Hi,

I use omada for management AP. My device is 2.4 ghz and it connects for second channel (screenshot is ready bottom) as more connection. But  

I sometimes experience packet losses.

Hey

 

Packet loss is to be expected on 2.4ghz, especially with 5 APs set for 40mhz widths.   The 2.4 spectrum is very small and in nearly all scenarios congested, to reduce packet loss change to 20mhz channels only and spread out your APs on channels   1    6    11      6     1    to avoid interference, you may need to set each AP manually.   When using 20mhz widths you will get more capacity and less interference, resulting in fewer errors / retries but at the expense of speed.  20mhz can support 3 non overlapping channels, 40 you are down to just 2 channels, with this many APs I personally would be running 20mhz channels

 

In relation to your camera issue, you mention its connecting to the AP on channel 2?    Try changing this camera manually to 11 and see if when you reboot the camera it decides to connect to another AP.   It may be that that specific AP being channel 2 is the first it sees and therefore connects too it

  @Philbert My camera is running at 2.4ghz. And it only works stably on channel 2. When I set the channels to auto, it connects to the remote Access point. Packet losses are rare in the 2nd channel and near the access point. What I want is to connect to the nearest access point under all conditions and to have no connection problems. When I tried before, I could not run it at 20 mhz.

I think you mis-understand what I was proposing, do not use AUTO for the channels, instead set each AP for a specific channel when using 2.4ghz.  

 

Start with the one nearest the Camera and set it for channel 2 as you require

Next nearest, set to 7

third nearest set to 11

4th to 6

and 5th to 1

 

Hopefully then the camera should connect to the nearest AP on channel 2 as you desire. 

 

This should give you enough frequency space between the APs to address interference.  Sadly 2.4ghz is known to be congested at the best of times so you will get errors / retries for sure.
