How far is the distance between EAPs?

About 30ft, but i have the power set low 

 

How far is the distance between the EAP and the controller?

All 4 EAPs are about the same length from the controller

 

Try changing different channel and channel width, better to optimize the wireless network environment.

All EAPs are already optimized for best channels and bandwidth 

 

 

See above, I started to get good results with ping for one of my clients but when I checked again after 9 hours I am once again seeing drops and high pings of 3000ms on some tests. It seems the EAP 225 performance is worse than EAP 245 especially on 2.4GHz.

The EAP225 is closer than the EAP245 when taking into account for physical distance, both have 80% or higher signal strength to the client. 

EAP245 with 100 pings to the same client:

Average 9ms 

Max 293ms

EAP225 with 100 pings to the same client:

Average 336ms

Max 1222ms

Again its not a channel or interference issue, the clients and APs are stationary, the 225 is physically closer to the client. The APs are not that far apart either just different floors but channels do not overlap, I ran the built in scanner to optimally select the best 2.4GHz channel.

I should not be seeing such high pings and poor performance on the 2.4GHz on the 225 while the 245 is working just perfectly. 

At the moment I have just disabled 2.4GHz band on the 225 as it is completely unusable. 

The 5Ghz band has dropped frames are errors as well on the 225, while the 245 has none and i mean 0%.
