I finally managed to set aside some time to do the few initial "black box" investigations. I tried varying the WiFi connection speed on the ADSL router and the kernel version. I also tried Ubuntu Natty as well as Debian Testing, both the 2.6.38 kernel and 2.6.39 kernel -- Natty only has a 2.6.38 kernel as far as I can tell. The 2.6.38 kernel works fine with the router at "upto 270", "upto 130" , and "g only". The 2.6.39 kernel fails to work on higher loads at "upto 270" and "upto 130", but works fine at "g only". The deduction from this is that something has changed in the 802.11n aspects of the 2.6.39 kernel that either: -- has diverged from the standard as implemented in the router. -- has corrected a divergence from the standard, that is incompatible with the router. I am sure there are other possibilities, but these seem the most obvious. I will put this anecdotal data onto the Netgear forums, to see if anyone at Netgear cares. Hopefully the folk upstream in Linux land (especially iwlagn land) already do.
