I run mainly run Gentoo, but have the same rtl8712 driver problem with several other distros. On the gentoo forum, there's a kernel 3.2 thread, and I posted a work-around that works, but I guess it really needs an offical patch (beyond my expertise, or I'd submit one). http://forums.gentoo.org/viewtopic-t-901702.html Anyway, here's some info I posted, which I hope helps. (On the forum, they wondered if this info had been passed along upstream):
This information had not previously been passed upstream.
FWIW, I have a work-around for my wicd and wireless connection failures with all 3.2-rc's and 3.2.x's. I simply copied over the entire linux-3.1.9/drivers/staging/rtl8712/ folder to the 3.2.0 kernel source (replacing the newly patched 3.2.0 version with the 3.1.9 version), and recompiled 3.2.0 using my current config file, and wicd and wireless now work normally.
In that rambling thread from the Gentoo forum, I failed to see the USB ID for your device. Use the command lsusb to list it.
I believe there is a regression in r8712u *for your device*; however, v3.2 works fine on mine. As you can understand, I do not have an unlimited budget for purchasing test devices, which is why your device was not tested earlier. As you have seen the source, you know that there are a large number of devices handled by this driver. Either your device is not in the USB device tables (unlikely), it requires some different coding, or there is something incompatible between the new code and your router. I checked to make sure we did not miss any IDs in the update. I don't think we did, but there is always the possibility.
If there is something unique to your wifi device, then we may need to bisect the code to see what went wrong. As I suspect that bisection is not your strong point, I just purchased an RNX-N180UBE on E-bay so that I can trouble shoot this problem. Once I get it and do the testing, then we will be able to determine if your router is the problem.
