Wireless printer losing connection hourly.

[ottoale1958]

I currently have a Cisco 4400 wireless controller running 7.0.116.  We use Cisco 1262, 1242 and 1210 Access Points. I am fairly new to all this. Our issue is that we have a wireless laser device that runs fine for about 1 hour and then loses connection. I can not ping the device and the web page via IP is no longer reachable. The printer regains connection after a power off/on. I have talked with the manufacturer and supplied logs to them and they say they do not see anything. Other devices in the office are running fine. I am wondering if there is a setting closing idle ports. The only clue I have it that it appears to be when the device is idle.

Hello,

I understand that your printer gets dissconnected from the Wireless every hour. Do you have "enable session timeout" enabled on the WLAN? If so, it can be the reason why it get's disconnected.

To change that pls go to WLAN > Advance settings and uncheck the option or set 0 there.

You mean on the 4400 controller?

[josuvarg]

Yes on the WLC!!!

It is set to 4 hours. The disconnects were happening 30-40 minutes. We have gone an hour since the last one. Very odd. Looking through controller logs and debug data. Thanks.

Ok... Please check the advance settings on the WLAN.

There are some settings that may create problems on some clients, like MFP, Aironet IE, band select and load balancing. It is a good idea to check disabling them.

Also, the "debug client [client mac address]" will help us to understans why it gets disconnected.

[ottoale1958]

MFP is optional

Aironet IE is unchecked

Band Select is checked

Load Balancer is unchecked.

We have gone 3 hours now without issue, there was one change made. I noticed that the time on the printer was manually set and lagged the network time by 6 minutes. I corrected that and we have been without issue since. Without a time server paying attention does the 4400 WLC or WPA2-PSK/AES have any sensitivity to that? Security time out caused by time issue on peripheral device?
