Hi There,
We have a single IAP-225 on it's own with the latest firmware on it, which we are connecting around 10 devices to(3-4 laptops,2-3 iPhones, iPad's etc), now I've tried and tried but for the life of me cannot figure this out.
NOTE:
Initially we had this working with LACP, so for testing, I took it off LACP but it didn't make any difference(currently it is not on LACP). This is a standalone AP, not part of a cluster.
So the steps I took:
1.) Factory reset
2.) set up 1 new SSID with default settings, WPA-2 Personal.
3.) In the System tab I set the prefered band to 5 Ghz
4.) In the RF tab I change the following:
4.a) Band steering mode: Prefer 5Ghz
4.b) Valid 5 Ghz channels = 116E, 132+, 124+, 116+
4.c) Valid 2.4 Ghz channels = 8,12
From here the devices connect, Band steering mode barely seems to work as devices capable of 5 Ghz more often than not, connect on the 2.4 Ghz frequency, rarely a device may connect onto the 5 Ghz.
My problem starts with the picture below, it seems as though even if all devices are almost next to the AP the stats are like below, with the Signal often beeing close to 20-25, for iPhones especially it's terrible, almost always at 14 or 10.
Below is an example, doesn't exactly show what I get but mostly the Signal hovers around the 25 mark and the speed is a bit lower than that on GN, for iPhones the Signal/Speed is almost always at a combination of 14/30.
Then comes the speed which is always quite low, marked in orange or red, I don't understand why it does that, I've tried almost every combination of options and nothing seems to improve it, I have adjusted the channels to where it has the least interference so the IDS shows very little as interfering. I've tried checking the debugging on the AP but am not familiar enough to know where to look.
Another problem is that if it DOES do AC or AN then either the Signal or the Speed is lower, so it always look like 10/150 or 90/5, it never has good numbers for both.
Lastly, if I change the SSID band setting to "5Ghz"(see picture below for example), it goes completely, no device is able to see the SSID at all, what makes it worse is when I change the setting back to "All", devices connect, but NEVER on the 5 Ghz frequency, no matter how many times I try and disconnect/reconenct them, they ALWAYS go to the 2.4Ghz band.
This is the setting I change:
I have tried and tried differnet combinations of all settings and cannot figure out why this is happening, the effect is of course poor wireless performance, setting the Band steering to "Force 5Ghz" makes absoloutely no difference. If anybody can help with this it would be greatly appreciated, have spent days trying to figure this out and am getting nowhere.
Kind Regards,
Nisha
