Decreased battery life on company WiFi

[bernd_zierhofer]

our mobile phones have a decreased battery life, when they are in the company wifi. if they are off the company wifi or in a wifi in the employees homes, battery life is normal.

we are using vSZ with R700/R710 APs. 

are there any settings we could try?

Wild guesses: Do you have any sort of "disconnect idle users after ____" setting?

Have you tried sniffing the network and seeing if there's a lot of broadcast/multicast traffic that devices have to respond to, like Bonjour?

Ruckus defaults to a DTIM of 2, which should help save battery life over "constantly aware mode" DTIM=1.

You can increase DTIM on a per-WLAN basis, but it needs to match what the phones are using.

These are AP CLI commands.


- First find the WLAN number in your system:

get wlanlist

rkscli: get wlanlist

name status type wlanID radioID bssid

-----------------------------------------------------------

wlan0 up AP wlan0 0 00:1d:2e:02:79:09

wlan1 up AP wlan1 0 00:1d:2e:42:79:09

Then apply the setting to all voice WLANs.

set dtim-period wlan0 2


set dtim-period wlan1 2




The dtim-period setting can be done either by SSH to each access point or via the Controller to all

access points with the command below.

debug#remote_ap_cli -A set dtim-period wlan0 2


debug#remote_ap_cli -A set dtim-period wlan1 2

Hi Michael,

i have tried the DTIM 2 setting, but it does not help. Also Broadcast/Mutlicast is not an issue here, i have tested with a seperate network, only 4 clients in it.



the device was sitting on the desk, with no interaction. see the drop in the screenshot.

Bernd,

   Can you open a ticket with Tech Support, and help us take a wireless capture
in order to determine what is really happening?  Thanks!
