We have about 185 AP's (AP121) in our network. Users get a VLAN assigned (802.1x) according to their group membership (VLAN's are available on all AP's), so they get the same VLAN where ever they connect.
All AP's are in the same management VLAN and in the same Hive. We use HiveManager On line.
Today, while scanning with InSSider (following up on some complaints we received) I noticed that my laptop remained connected to the first AP I was connected to entering the building. I took over 5-6 minutes before I was connected to the AP with the "best" signal quality.
Are there any settings (AP, Hive manager) I can adjust to speed up the roaming process?
Thanks in advance!
Do you have tested with different clients? Know that it is mostly the client that take the roaming decissions, not the ap.
Thanks for the quick reply.
Yes, we received this complaint from different users, using different clients and OS'es (ios, windows, android). Some of them where standing directly under an AP and where still connected to their "previous" AP, it sometimes took minutes before they where connected with the new AP.
I'm not at all familiar with these settings but I have read some info about the possibility of layer2/3 roaming and a caching option within aerohive ...
An other cause of sticky roaming is the use of load balancing (clients sometimes won't reassociate at AP's that are crowdy and load balancing is configured). Is this configured at your network?
no, that option's not configured.
Thanks Mike and John!
John would it be possible to point me in the right direction?
Am I correct that radio rates are set on the SSID?
How do I configure this correctly?
The threshold you should set to really up to your wireless network but 25 dB is considered a good SNR so 15 to 20 dB could be suitable.
We set the 2.4 and 5 ranges to 12MB.
Then we created a radio profile to set the power and channel settings. Create the profile and under the advanced settings (we) set MAX Transmit Power to 10. And channel setting t oadjust channels every 10 minutes.
Will try these options and will report back!
