The symptoms were = that the router worked, but not very well. Speedtest was gave miserable = speeds; netalyzr didn=92t work at all. (It said there were serious = problems: see = http://n3.netalyzr.icsi.berkeley.edu/summary/id=3D36ea240d-26536-45539c09-= 7334-456b-b81a ) I was able to download the proper system upgrade = firmware, but it took forever. Don=92t do it :-) - After installing the proper image (for WNDR3700v2), PPPoE didn=92t = immediately come up on my 7000/768kbps ADSL from Fairpoint. I had to go = to the Edit page for the ge00 interface, and click Apply (without making = any changes to the saved settings). This caused the link to come right = up. - The henet 6in4 tunnel did not work. The router received the expected = global IPv6 address, and handed an IPv6 global address to my notebook, = but neither the router nor the notebook were able to ping = ipv6.google.com. I removed that interface from the configs using the = GUI. - Had to enable and set AQM parameters, since they=92re saved = differently from the QoS settings in the 3.7.5-2 firmware. Set = parameters to ~ 90% of link speeds=20 - The kernel.log shows lots of the stack traces below: 2-5 per second on = a long-term basis.=20 - This may be related to the netalyzr test - after netalyzr completed a = run that complained that nothing worked (see above), these errors = stopped for a while. - However, using NetalyzrCLI.jar, I got the following results where most = everything worked: = http://n2.netalyzr.icsi.berkeley.edu/summary/id=3D43ca208a-24217-0cc69e65-= e649-4be6-b2c5 - The PPPoE running on ge00 link seemed to bounce every 10-15 minutes, = and I often had to bring it up manually. - Reverting to 3.7.5-2.
