Controllerless Networks

Hi,

I am new to Aruba accesspoints, I have 4 IAP-105 APs without controller (One of them acts as VC) installed in 4 floors of a building. In the GUI i can see them 4 together. I am experiencing, one of the AP in the middle floor often reboots (or the clients looses connection). The firmware in all the APs are 6.2.0.0-3.2.0.2_37229. All are static IPs and these IPs are excluded from the DHCP.

I can see some interferences as seen in the below screenshot. What does the number mean in the interfering and valid metric? are they count of interfering APs around me or channel number? This interference may cause the disconnection?

Any helpful hints are appreciated to resolve this disconnection issue. Thanks in advance

I would begin by updating the SW version.  3.2.0.2 is several major versions old.  The current version is 4.0.0.4.   To upgrade go to the Maintenance tab -> Firmware -> Check for SW Updates.

Interfering APs are just other APs in the area that may be on the same channel as yours.  ARM will choose the best channel for your IAPs based on what each IAP hears in the air.

Hi Marcus,

Thanks for your quick update. I have checked for newer updates many times but i get message no updates available. To my surprise now, i checked again and found there is new update! Now i am downloading the image and updating. Let us see it will solve the issue.

Would you please tell me what does the number means in the interfering graph i sent? Is it number of APs interfereing or channel?

The firmware is updated to 6.3.1.2-4.0.0.4_42384. Is there any configuration checks i have to verify?

Download a copy of the IAP 4.0 Users Guide.  Chapter 4 Table 10 provides a description of Interfering APs, Rogue APs, etc.   The number in your screen capture represents the number of Interfering APs heard in the air.

Thanks for the update. I will download the userguide. Just a quick question, The interfering APs cause the frequent disconnection of my APs? How can I reduce the interference?

I appreciate your support.

bash,

The interfering access points are just access points that can be seen, even on other channels, by your access points.  It does not guarantee that they are causing your issues.  Please see the thread here:  http://community.arubanetworks.com/t5/Aruba-Instant-Cloud-Wi-Fi/Best-Practice-IAP-deployment/m-p/126555/highlight/true#M3694 with important points.

Once again, if you have only a single access point for each floor, how big is the square footage for each floor?  Do you have enough coverage?

Hi Marcus,

Thanks for your support. Since the upgrade i have not noticed the disconnection.

Thanks again.
