Hi, With the rtl8192ce driver, I get freezes a few seconds after connecting to a network. (see PCI id below) Machine is unusable after hang. I'm using the linville/wireless-next git tree. I've been playing with the different options, and noticed that setting fwlps=0 fixes the issue. I've tried to get more messages with netconsole, but once the lockup happens I'm unable to get any debug message (regardless of the log level of the driver).

I have been doing long-term tests with that same card for about one week with no dropouts and no freezes. I am running wireless-testing, not wireless-next; however, I have all the rtlwifi and friends patches applied. I think it is safe to say that I cannot duplicate your results, and that we need to explore the rest of your system to see what is different.
Is your system 32- or 64-bit? How many cores in your CPU? Have you tried connecting to more than one AP? What is the make and model of the AP that needs to have power save turned off? What is the mode of operation?
I am using a 64-bit system with a dual-core CPU. My main AP is a Netgear WNDR3300 running standard firmware and is encrypted using WPA2-TKIP (AES). The mode is 802.11n at up to 270 Mbps; however, I have also tested using a Linksys WRT54GL running openWRT Kamakaze firmware. That one is 802.11g at up to 54 Mbps.
