Can you confirm without ipw2200 the memory shortage doesn't happen? Did you enable fragmentation (tell from iwconfig output) btw? The error only appears under *heavy* network traffic. That's a situation I cannot reproduce without ipw2200. Fragmentation is off. Maybe you can try it on wired network? i.e connect to your AP with an ethernet cable? |
