Hi Jonathan, first of all, thanks for answering my email ;-)
I found it was caused by my router, smc-7908/arcadyan ARV7518PW-A-LF-LT. It seems to be that when signal is not good enough its implementation only allows clients running windows os to connect. I have a cordless phone base and when I place it near the router no machine running linux is capable of connecting, although some times they connect for 2-3 minutes and disconnect showing the same error. I've two laptops (with dual boot, windows and linux) and a computer with a pci card (running linux). When running windows it takes them a little bit longer to connect, but once connected wireless works perfectly. I fixed it just by removing the cordless phone, but maybe I can help to find the problem. I answer your questions below. One more thing: iwconfig power off this is a fix only for driver rt2500pci when it fails to enter state 1 (-16): .... rt2500pci 0000:02:0a.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22 phy0: Selected rate control algorithm 'minstrel' Registered led device: rt2500pci-phy0::radio Registered led device: rt2500pci-phy0::quality .... phy0 -> rt2500pci_set_device_state: Error - Device failed to enter state 1 (-16). .... > I suspect the signal is weak. When I place my laptop below the router the signal is 100%, but the problem is still there. > Does this always happen within a few minutes of connecting? Not always, some times it is not capable of connecting. > Does the signal strength matter? I do not think so, but I'm not an expert ... ;-) > If you have other wireless hardware to try, do they produce the same problem? Yes. I tested on rt2500pci, Intel(R) Ultimate N WiFi Link 5300 AGN, REV=0x24 (iwlagn) and zd1211rw 1-6:1.0: firmware version 4725 (zd1211rw 1-6:1.0: zd1211b chip 0ace:1215 v4810 high 00-1a-ff AL2230_RF pa0 g--NS) > Do current kernels behave the same way? Yes. I now have linux-image-2.6.32-5-686 (2.6.32-35) both in a laptop and the computer, but I tested bpo kernels in both. In the other laptop I have linux-image-2.6.39-bpo.2-amd64 (2.6.39-3~bpo60+1) and linux-image-2.6.32-5-amd64 (2.6.32-35). Some times they connect for 2-3 minutes and some times they do not connect. > Does downgrading the kernel to a version that worked before make it go away? I tried kernels in stable and forcing a downgrade of all packages from bpo to stable, but it didn't worked. If you think that this is caused just by the router (I think so), just close the bug. I do not know why windows os works, but sw inside this router is a piece of crap and my only hope is the openwrt guys succeed in running linux on it ... https://forum.openwrt.org/viewtopic.php?id=15934 Thanks.
