I have a 871w connected to a cable-provider in Vienna, Austria.
The speed should be 16384 mbit download, 1024mbit upload. But I only get something like 3 mbit down, sometimes peaks of 5 mbit.
I run the test with an ISP-provided testsite (1MB file per PHP/HTTP), but I see the same data with tools like DUMeter. The ping is about 8ms to this site, and a traceroute show only ISP-routers in between.
The 871w has the most recent IOS (but I didn't check since three weeks or so), and I get the same results on LAN and WLAN.
So, just a simple question: what speed should the 871w manage on its FA4 (WAN) port?
