For a few weeks a had a broken network connection and it was accident that I noticed what had happened. The kernel 2.6.8 is broken for me as far as I can't change the broken router. No, your router is broken. There is a workaround as you desribe above. This is not a kernel bug. At least it should be noted in NEWS.Debian file. That sounds fine, can you please send a patch? -- Horms
