Touchstar Boston 8500 Handheld Scanner Disconnecting

[julius_kisieli1]

Hi all,

We have quite 40 Touchstar Boston 8500 (http://www.touchstar.co.uk/product_mo...) Hand Held Barcode scanners that connect via ZoneFlex 7352 controlled by a Smart Standby Zondirector 1100 to our network.

We have just started testing and what we have found is that the hand held units seem to "disconnect" from the network at random intervals (5-60 minutes) all sleep and power setting are either off or on max. The hand held still has an IP address but the device can no longer access the LAN or can be pinged from any machine within our network. To reconnect we need to put the device in standby mode and then switch it back on, this effectively restarts the network card.

The WLAN card that the handheld has is a Summit, I have found a setting that I thing may be responsible for the drop off's as it may interfere with what the ZoneDirector is trying to do: http://www.summitdata.com/Documents/G...

Agressive Scan is a feature in Summit WLAN cards that actively looks for better Ap's and try's to connect to them, from my understanding the ZoneDirector will transfer the device between Ap's? Would this be culprit?

Any help appreciated.

Thanks,
Julius

Is now CF on or off?

Hi Primoz, no CF is off. We thought that it would be better to leave it off to eliminate the amount of traffic going to the clients. Is it better to have it ON? What are the benefits?

[julius_kisieli1]

There has been a new development in the situation, we have added a few laptops to the wireless network and now the laptops are experiencing the same thing. So this is no longer isolated to hand held devices only. We have isolated the issue to occur while the connected devices are migrating between AP's.

Any thoughts any one?

IS it allways one or 2 APs that this occurs on or all of them?

Which FW are you using? Have you upgraded to 9.6.1? Did the upgrade go through to all the APs OK?

Do you have a spectral analyzer and an L2 analyzer you can use to help with this?

[julius_kisieli1]

Hi Primoz, it's all of them. We had also once thought it was one or two AP's but this has happened to many oof them

All I have is Wifi Analyzer app on my android phone.

We are still on FW 9.5.
