Estimated Capacity very low on AP R710

New Contributor II
Hiya All 🙂

I have a big problem into a building here, with the WiFi. 

Actually users complain about speed of APs, so what I already did :

- Did a complet site survey with Ekahau Site Survey
- Move/remove a lot of APs for remove Overlapping and get a good strengh of signal
- Remove the 2.4 Ghz, like that users can connect only with 5 Ghz. 

Unfortunetly, the last step was a disaster... users complain more than before. 

Specialy some girls who are on a specific room. When I see the information of the concerned AP, OMM it's not normal at all.

The estimated Capacity is very low and I dont know what's wrong and how I can solve the problem.

If anyone have an idea ?

Thanks a lot 🙂

Hi JS,

I checked the APs neighbour list and I see the overlap has come pretty less to 17 db and so. I am not sure how far the nearby APs are to Rolle -mo Rc access point.

I can also see 4,5 and 9 db which are apparently very less. Please make sure that 5 Ghz have shorter wavelength and they do not transverse through thick concrete walls. 

I would suggest to enable 2.4 Ghz first so that clients connects and then find the reason for low throughput. 

Check the throughput or speed using speedflex on both 2.4 and 5 ghz individually. Simultaneously check the wired speed by connecting a laptop to the switch.

By downloading the support file from the AP, check the phy errors and see if interfernce is not causing this.

If it is an issue with interference, try manual channels and see if that works.

Hope this helps.


Hello Ahamed,

Thanks a lot for your reply.

I dont understand this sentence : 

I can also see 4,5 and 9 db which are apparently very less. Please make sure that 5 Ghz have shorter wavelength and they do not transverse through thick concrete walls. 

I am going to enable 2.4 Ghz for this moment, as you suggest.

What do you mean by using speedflex on both 2.4 and 5 ghz individually ?

Yes a second test will be the testinf of the wired. 

I am novice on that kind of product, that's why my question are a little bit stupid I guess, and I would like to apologize for that.

Thanks again Ahamed 🙂

Hi JS,

I meant to say 4 db, 5 db and 9 db in neighbor AP list. The APs are overlappiing with very less overlap. But then these are using 5 Ghz. 

Speedflex is nothing but a ruckus propreitary tool to test the speed. Image_ images_messages_5f91c479135b77e247aacd3f_9126837672353a24bc3713579031a8bd_RackMultipart201604151023621dq-fb5cce1f-fcd0-4ba0-ac19-257c03734e8f-1289075863.JPG1460733304
You can find the speedflex on the monitor >> access point page. You can also go to clients and check the speed using speed flex as shown below.

Speedflex is also available in app store for iOS and android devices. 

Hope this helps.

It's best to confirm your wired layer is performing as a start.
Run a SpeedFlex to all your APs to confirm they're running gigabit speeds and that there isn't a backhaul issue.
Run a 10-15 second ping test from a machine at your core switch/AP switch to all AP's to ensure latency is good and there is no packet loss to APs.

Consider dropping your 5GHz from 80MHz channels down to 40MHz channels.

Walk around with a client laptop, one connected at 2.4GHz and one at 5GHz and run a ping check to test the latency in trouble areas.
Consider spectrum analysis in the trouble areas.
