I was wondering if anyone has tried to use the WiFiStix in a managed WiFi
deployment, for example on a campus or in an enterprise ?
Essentially I am looking for the case where there are multiple WiFi APs
(hence BSSIDs) for the same ESSID (i.e. network name).
Almost all WiFi interfaces (whether Windows or using Linux) monitor and
periodically scan for other WiFi APs either proactively
to look for better APs or reactively when the RSSI of the current AP
degrades. At some point if they find another AP with better
RSSI or channel quality they perform a layer-2 handoff to that AP.
Unfortunately the Marvell WiFi on the WIFiStix does not exhibit this
behavior and stays on the same AP even though the channel quality
degrades to levels where the gumstix cannot even ping the gateway. At this
point there are multiple other APs with the same SSID that
it could have switched to but doesn't. After losing connectivity it does not
even come back to the original AP when coming back in range of it.
Any idea how we can enable Layer-2 handoff (or roaming) or whatever it may
be called on the WiFiStix (Marvell WiFi chipset) ? I imagine this
is a driver / firmware functionality.
This is causing some major issues in my current application where there is
some mobility of the gumstix+WiFiStix.
