@mercenaruss 

Hi, Welcome to the community.

Could you please help me run a test:

1. Temporarily unplug the 7 satellite Deco M5 and only leave the main Deco.

2. Connect to the 2.4ghz and test the ping response again.

 Moreover, could you please also install a Wi-Fi analyzer on the smartphone to check the current wireless signal strength and interference on the same and adjacent channels?

Thank you very much.

Wait for your reply.

best regards.

@David-TP 

Hello David,
1. Unable to unplug all of them today,but will try on Saturday.
2. I checked with WiFi analyzer the frequency:

      -  One Wireles Printer was broadcasting,so was a overlap,disabled him.

      -  Did a optimizations,channel changed to 2

This is the current ping on 2.4 Ghz ,from 0,5-1m distance from Main Deco.

Any more advices,what can be done? Except testing only with Main Deco?

New information available.
1. I disconnected 4 Deco's,remain only 5.
2. I changed their locations for minimal overlap.

3. I change Main Deco
 

Problem still there,from any Deco point(Basement,Gr. Floor, 2nd. Floor, Pent House)
Below is scanner information + ping from respective locations:

1st. Location, 1 mtr from Deco, only 2.4 Ghz Enabled.

  @David-TP 
I disconnected all Deco except the Main One,
problem is still the same.
Tried 3 different PC's with different Wireless Card - the same problem.
Tried 2 different Phones,with ping activated on Main Router,the same.

Like i said before,only Ethernet Port on deco give me normal ping to router or servers inside network.

  @mercenaruss 

Hi, Thanks for the detailed information.

May I know the expected ping response time you wish to get over 2.4 GHz?

Based on your ping test, I can roughly get that:

So far, the ping is best when 2.4gh is on channel 2. So it seems like channels 1,7.8 are less crowded around the house.

As we know, 2.4ghz is always crowded since there are only 13 channels for use, and easily affected by other wireless signals, like Bluetooth, and Zigbee on the same frequency. Its ping reply time would not be as good as Ethernet and 5ghz connection. 2.4ghz is not a preferred band for live video or audio meetings.

Thank you very much.

Best regards.

  @David-TP 

I expect to have a ping not bigger than 8ms or to be able to setup different channels in different location of Deco.
To be 100% sure i installed 3 another Wi-Fi access points from another manufacturers,results are almost similat to this:

So now again i'm not sure whats wrong,if another 3 access point are performing very well,except Deco system.

 

  @mercenaruss 

Hi, can you also help me check the current wireless channels on this Wi-Fi Access point?

If it is indeed on a quite different channel, later changing the wireless channels on Deco might help.

At the same time, I would like to forward your case to the senior engineers to see whether they had any other suggestions.

Wait for your reply.

Best regards.

  @David-TP 

Hello, after many Network Optimisations, now in on channel 9.

Will connect today directly to router,without switch,but I assume this will not help,because like i said in previous post's that:  if using Ethernet Backhaul port on Deco,i have a very good ping (1-2ms) to router or servers in network. 

  @mercenaruss 

Hi, Thanks for getting back to me. I might not say it clearly and I was wondering what is the current wireless channel for Wi-Fi access points from another manufacturer on which you could get the following ping test result, not the channel of Deco:
