The rtl8192de driver is working fine for me at 5GHz, but I am having trouble
getting scan results for 2.4GHz 802.11g networks. I have been doing a lot of
debugging but am not making much progress. I suspect the 802.11 b/g/n phy is
not being initialized correctly, but I'm pretty far outside my domain on this
one.
Is anyone successfully using this driver with a 2.4GHz 802.11g network?
I have several different models - some work better than others. What
is the PCI ID for yours?
This is the one I have:
02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:8193]
02:00.1 Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:8193] (rev 01)
It turns out that both kinds have the same ID. I think one of them
is a prototype, while the other is probably a production unit.
Obviously, bitrot has set in while I wasn't testing. With the kernel
driver, neither unit can even scan in the 2.4 GHz band. Using the
latest version of the vendor driver, the production version connects
with APs running WEP, WPA, or WPA2. The prototype can only handle
WEP.
Obviously, I have some work to do. In the meantime, I will send you
a tarball containing the vendor driver - privately so as not to spam
the list.
Thank you, I appreciate that.
Of course, my preference would be to fix up the kernel driver. I don't mind
doing some manual bisection with compat-wireless releases unless you think that
would be a total waste of time. Do you have any sense for what the last working
kernel version would have been?
As you suggest, we may need to use the vendor driver in the meantime. Thanks
again for sending it over (although I suspect it is the same version I
downloaded from Realtek's web site).
It started with the Realtek version, but has some important bug fixes that I
wanted you to have.
Of course, we want to fix the kernel version, but if you want to bisect
compat-wireless, that would be a big help. In the meantime, I will try bisecting
wireless-testing when I get a chance.
