" Just a note for 20mbps users - if you have a Router, note that 20mbps is probably the last upgrade you'll be able to take advantage of - because the interface between WAN and LAN parts of your Router may not be able to handle the data.

Some Router's may not even be able to handle 20mbps. You'll need to check the specs of your Router, and this particular tidbit of information isn't always given!

Just because it has a 10/100mbps WAN port and the LAN ports are also rated at 10/100mbps - this doesn't mean that the router can deliver it. Those speeds refer to the actual switch performance and receive performance of the WAN port - not the WAN/LAN interface, which is limited by the Router's processor performance.

So expect to see a bottleneck soon.

To find out if that's the case with your Router you will need to plug the modem directly into a PC and measure the performance in both domains. "
