[laptop-discuss] ndiswrapper with BCM4306 loses downstream functionality after a few minutes

[Brandon Barker]

I purchased an atheros based Netgear WG511T (it was what was available
at the local Best Buy Store) and it has worked great so far.  In the
mean time I still eagerly await suggestions on how to debug this
issue; I am trying to read up on Dtrace and eventually kmdb but I'm
not sure if I'll ever have the opportunity to become fluent with the
ndis driver itself =(.

Thanks,

Previously I used the linux ndiswrapper with no trouble at all.   After  installing solaris and the ndiswrapper (I downloaded a separate windows driver than the one I used in linux), things seemed to be fine, but after a while of using the wireless connection the system would hang and then reboot itself.  At the time I wasn't sure if these were the same windows drivers that I had used before (they had the same name), but luckily I backed up the ones I used in linux.

Now the system no longer crashes, but downstream activity nearly stops all together after several minutes of heavy downstream activity (like downloading some large file).  In fact, I thought it did stop all together, but if I try to SSH in to the laptop, I do eventually get a prompt (after about a minute).  When I do "ifconfig -a", it prints out the info for the device, but it hangs so I have to Ctrl-C to exit.  I can't use modunload to remove it either, and having ifconfig attempt to detach does nothing.

Just let me know what info you would like to see; I'd love to learn more about this as well as get it fixed.   If anyone has any ideas about a way to at least get it going again without rebooting the system, that would be a good temporary fix (and allow me to test more easily).
