Whats the possibility of this being my problem?

[ampz]

Basically I have a surfboard 4100 and theres a new Motorola surfboard 5100 out. Someone said in the past that the 4100 has a cap on it etc. and they got the 5100 and got awesome speeds. I have the 6mbps package and I'm only getting 3.9 mbps which is horribly sad. I've done everything to try to tweak my speed from cablenut to a fresh windows install and nothing has helped me at all. I called comcast and they told me they see the line as being fine and told me to go tomorrow morning to get the newest modem. Whats the odds of this being the problem? Is there anything else that could be my problem? I will give any information asked of me if you need to know more information about the situation before you can comment on it. I would appreciate any feedback. thanks!

hey ampz

usally it is modem / router that messing up speed, if your ISP claim your line is fine.

also some NIC have problem with duplex mode

if you connect direct to modem, i suggest 10 Mbps half duplex, you can also try 100 Mbps half duplex

but if your connecting via a router, then always use 100 Mbps full duplex

If you bypass and connect direct to modem, you will know if its the router or not

Update I tried force 10 half duplex and the speed was REALLY bad, at force half 100 it was what im usually getting which is about 3mbps (half of my package) and this is directly to modem i.e. no router connected. My NIC is NVIDIA nForce MCP Networking Controller (which is on-board I believe) im not sure if my NIC sucks or whatever but do you have any good nic suggestions or what else can be the problem?

You should be able to get advertised speeds. According to the 4100's data sheet http://broadband.motorola.com/modem/SB4100.pdf  <-pdf file the 4100 can go up to 38Mb
