We have tested the Colibri module with the following Wifi chips
- LM technologies - LM821 (Realtek RTL 8188CUS chipset) http://lm-technologies.com/product/wifi-smt-module-150mbps-with-ufl-receptical-lm821/
- Sparklan - WUBA-171GN (Atheros AR9271 chipset) http://www.sparklan.com/p2-products-detail.php?PKey=165dTr_MFn9dBglbfDIFMYEfkjdkOAcsBetxkHnXhA&WUBA-171GN
The first adapter from LM response stable and reconnects every time using connman.
The second adapters has the specs we need for our solution but stops auto reconnecting after a random timeout (could be hours or few days). We are using connman as the connection manger.
We already tried using a powered usb hub to rule out any power issues. The module is wireless connected to a WPA2/CCMT secured network. The accespoints are provided by HP and are centrally managed.
We are running on the latest V2.5B2 image.
Are there any known problems with the Atheros chipset in combination with the Colibri module or do you have any kind of suggestion?
