I have identified one issue that looks like it's contributing to the problem. This isn't a kernel bug, but a problem with the data from the router that causes mac80211 to disconnect from the current AP and roam to another one. The test kernel linked to below contains a workaround that _might_ help, if the AP is also sending us the same information in another way. Please install this kernel and then attach syslog after using it for a little while. Also let me know whether or not it's working any better.
