We tought this could be some kind of bug in the ZEBRA WiFI driver for Android (FUSION_BA_2_00.0.0.021), maybe releated to radio a particular radio frequency. The good thing is that the error can be reproduced and we are able to fix it, anyway it shouldn't happen since all other devices are working fine and they can reconnect without problems. This operation does not hard-reset the AP.ĥ) After fixing the problem by doing the "trick" specified on poing 5), the connection works even on channel 36EĦ) All the other type of devices (Android smartphones, Windows PCs and other non-ZEBRA Android handeld computers) don't experience this issue If the reconnection happens in another channels, it works.Ĥ) We can fix the problem by just going into the infrastructure control panel and re-saving the configuration for that particular AP. After repeated tests we see that after reconnecting the problem occurs only on this channel.

(AP1 and AP2 are just examples, this is valid for every AP)ġ) After the reconnection, the device connection status "looks" fine (there's the wifi icon with full signal, it has an IP address and all other network settings look as before, no errors on the FUSION logs)Ģ) The real problem is that the device is isolated (unreachable host error is thrown if you try to ping from and to the device)ģ) The problem occurs only on WiFi channel 36E.

Following ZebraNet, Martonosi worked on a DTN system to connect rural parts of Nicaragua, C-Link, and SignalGuru to share vehicle data. the TC51 connects to AP2 while the first one is restarting From a cost perspective, collaborative dynamic DTNs and mesh networks seem like a very helpful technology direction. we shut down the AP1 from the control panel, or by removing the power supply the TC51 terminal is connected and working fine to AP1 We're experiencing a weird issue which can be reproduced by doing the following: The radio frequencies are managed by the system which ensures that each AP do not interfere with the others. The infrastructure is composed by serveral access points, one of them acting as a master. We just set up a WiFi infrastructure to use few handeld computer TC51 in our warehouse.
