Issues after upgrading to Aruba OS 6.1.3.1 - Slow speed and mobility problems

Hi,

We have two Aruba 6000 controllers and around 200 AP 125 at our campus. We are having issues of very slow download speed and  issues with Roaming users while they get disconnected from APs and have to re-authenticate. 

 

I have few questions. If you can answer only few of those please answer. 

 

1. What is good SNR value? I see clients in all SNR ranges from 0 - 6. ANything can be done to improve?

 

2. What is Goodput? Is there any minimum acceptabel value?

 

3. What is Noise Floor? Any significance?

 

4. What is channel busy? Any acceptable values?

 

5. What is Interference? I see most of it between 0 - 10.

 

6. In potential issues section, I see Busy Channel issue with 2.4 GHz? WHat does it mean? In Low Goodput I see a lot at 2.4 Ghz and a good number at 5 GHz. ANy significance of it? 

 

7. For some SSIDs I see "Frame Dropped to Client" value of 17%. It seems high. Any comments? 

 

8. I also see some 11 - 15% for "Frame Retied from Clients". WHat is significance?

 

9. For APs, how many MAX clients per AP is acceptable? What is acceptable Noise Floor? 

 

10. For clients, I see a, g, HT. What is HT? Where do I see "n" clients?

 

11. Should my clients have "a", "b", "g", "n" capability? Is there any problem if a client has less capability, meaning only, b and g?

 

12. For APs, some APs have 2.4 GHz and 5 GHz band, while some APs have only 2.4 GHz band. Why so?  

 

Thanks

San

I would look on the page here:  http://www.arubanetworks.com/technology/reference-design-guides/

 

Download or look online at the document called "Optimizing Aruba WLANs for Roaming Devices"

Thanks but there are 25 large documents. Is there a quick ref guide?

Unfortunately I am unable to get to any of the documents on the Aruba site as I am unable to register because our controller is branded Dell (w-650). Is there any other location/way to view docs?

That login is for Airheads, not the Aruba support site.
