Does AP310i connected in line of site cause any slow speed or coverage issue due to interference?

In our HO we have VX9000 controller installed along with 2 310i Access points connected in line of site to each other. Users complaining slow speed issue also coverage is less.

Please refer attached floor plan along with access point placement marked in yellow.

Please let me know if the 2 access point in line of site causing any issue? How can I confirm what is the issue?

Normally I’d expect that the AP profile has auto channel selection enabled so the AP could choose from 1,6,11 on the 2.4GHz band = if 20MHz channel width is enabled (you shouldn’t use 40MHz on that band).

Regarding the 5GHz band and non overlapping channels it would depend on which channel width is used only 20MHZ or 40MHz (=2x 20MHz channels bonded), 80MHz (=4x 20MHz channels bonded).

For 20MHz there is no overlap, if you’ve 40MHz you’d run on AP on channel#36/40 and the other AP on channel#44/48.

Thank you for the update. So do I need to manually go to each AP and change the channel correct? 

What about 5GHz band same applies to that also? If yes what are the non overlapping channel in 5Ghz band?

[Ronald_Dvorak]

You should make sure that APs DON’T use the same channel.

I.e. AP#1 on channel#11 and AP#2 on channel 6

If both operate on the same channel in near proximity that could result in interference and also that clients use all the same frequency = lower throughput.

As it is an controller based solution. All APs have same configuration as same AP profile applied to all the APs.

2.4Ghz using channel 11.

Actually our HO shifted to new location. In our old office we were using Enterasys C25 controller with AP3610 & physical dimensions, mounting position and AP count per floor was different.

TX power is by default selected as smart.

So my concern is if we remove one AP and connect only one AP will it give us better results?

or If we place 2nd AP in non line if site location means both APs can not see each other. Will this work?

Hi,

interference could only happen if both APs operate on the same channel (or neighbour channels in case 2.4GHz).

What channels to the two APs use for 2.4GHz and 5GHz ?

Was that a replacement and the “old” APs had better coverage > what tx power is used on the APs for both bands.
