This page lists known issues related to the Wireless Driver, pointing to track numbers and suggested driver patches (where applicable) to fix the issues.

Probe Retry Limit

Probes Request/Response for/from XOs are maintained for the sole goal of not breaking ad-hoc mode (which can be implemented passively and, in the end, brings no obvious advantages over the mesh mode). As it is a very bursty and demanding control traffic, particularly in dense networks, the number of retries, currently set to 2, should be reduced, if not removed altogether.

5.110.22.p6 allows probe response retries to be set from driver, from 0 (no probe response) to 15.

But a driver patch is required and be found here.

Not responding to RREQs

In this bug, the XO stops responding to mesh path requests frames (RREQs). The main cause seems to be that the driver is not waiting long enough for the firmware to download.

A suggested fix be found here.
