Bad PPPoE performance with Cisco 871.

[Vieron82]

Hi!

I have a 80/25 Mbit Cable link, but it uses PPPoE for authentication of users.
When i connect my laptop directly, i can achieve 95/40 MBit according to speedtest.net, but when i use the 871, the speed drops to 35/33 Mbit.

Is it a misconfiguration?
