Description
Wifi card Intel N6235 in the revision 56168 works poorly, unstable. It spontaneously disconnects and loses its wifi access point. Revision 56147 works perfectly, a stable wifi connection. It is likely that the bug appeared in the revision 56148 - 56158.

Can you please test with hrev56154 and see what happens? Either way, upload a syslog from that revision.

I dug out the laptop I have which uses this driver (though with a much older device), and unfortunately the bug does not reproduce on hrev56168 here; the device works fine. I downloaded a bunch of stuff with no problems...
I guess we are going to have to go the old-fashioned route to debug this then. I'll build a test driver or two and we will go from there I suppose.

Here are two versions of the driver to test with. Please use the latest version of Haiku itself, and blocklist the driver before booting.
Test with the iprowifi4965-1 driver first. If it works, then test with the iprowifi4965-0 driver also. If it does not work, please upload a syslog. (If it does not work, then do not bother testing with iprowifi4965-0.)

OK, thanks, that info was helpful. Try this version and see what happens, please.

Excellent, that narrows down what the problem could be. This new version should behave the same as the previous one, but it will print a lot more information to the syslog, and hopefully I should be able to determine what the fix needs to be from that.
Please use it for a while (10-20min or so) and then upload a new syslog.

Thanks. I think I found the bug this time; it was a monumentally stupid error on my part.
If this new driver works, I will commit the fix and close this ticket. Thanks again for your patience in testing this.

I've committed the fix in hrev56182. Thank you very much for patiently testing all the different builds!
