I posted last week similar observation. My atheros based pccard only works if inserted on boot, or at least before starting any memory heavy applications such as Mozilla and OpenOffice, while XEmacs is no problem. If I insert the card after I have started Mozilla, I need to reboot to bring it up. I have also observed the "No buffer space available" error. It appears that the card needs a reserved continuous chunk of memory to work properly. As you use your laptop, some apps fragment the memory. I have also experienced that if the card has been idle for a while it sort of disconnects. Using arping I can get things up again, but not with a simple ping? I don't think usin NDIS will solve the problem. AFAIK NDIS is for use when everything else fails or a driver is not available. Cheers, Erik BTW, I'm on 6.0 but I don't think this makes any difference. -- Ph: +34.666334818 web: www.locolomo.org S/MIME Certificate: http://www.locolomo.org/crt/2004071206.crt Subject ID: A9:76:7A:ED:06:95:2B:8D:48:97:CE:F2:3F:42:C8:F2:22:DE:4C:B9 Fingerprint: 4A:E8:63:38:46:F6:9A:5D:B4:DC:29:41:3F:62:D3:0A:73:25:67:C2
