Unfortunately, since I've done so, my connection drops from time to time, and I usually don't notice for a while. The period between drops does not seem to be constant, however, as I lost my connection at some point yesterday without noticing, but when I did notice I reestablished contact, then lost my connection again a few minutes later. The connection has not dropped again since then, however. I'm using an Intel 2200BG adapter (Centrino chipset) with WPA encryption and the wpa_supplicant connection manager. My wpa_supplicant.conf: ctrl_interface=3D/var/run/wpa_supplicant ctrl_interface_group=3Dwheel # netwerk network=3D{ ssid=3D"netwerk" psk=3D"ssdpbwqaougj6hr9" } (PSK changed to protect the guilty) When the connection drops, I get the following in /var/log/messages: Jun 9 23:14:21 hostname kernel: iwi0: link state changed to DOWN Jun 9 23:14:28 hostname kernel: iwi0: scan stuck Jun 9 23:14:34 hostname kernel: iwi0: could not allocate firmware DMA memory (watch the line wrap) In case it isn't obvious, "iwi0" is my wireless interface. All /va/log/dmesg seems to show is this: iwi0: link state changed to DOWN iwi0: scan stuck Any ideas on where to go from here would be appreciated. Is this a driver bug, or am I doing something wrong? Another (effectively identical) laptop running Debian does not have this problem. --=20 Chad Perrin [ content licensed PDL: http://pdl.apotheon.org ] Bill McKibben: "The laws of Congress and the laws of physics have grown increasingly divergent, and the laws of physics are not likely to yield." --mYCpIKhGyMATD0i+ Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (FreeBSD) iEYEARECAAYFAkhOmtsACgkQ9mn/Pj01uKW8/wCgnwKS6tegExK8azeBXmHfarJT OFwAoNzsb4cOfTNfG/2271cCHPZHX6ie =k6ny -----END PGP SIGNATURE----- --mYCpIKhGyMATD0i+--
