I just bought a brand new 871W router and I am trying to configure it with the provided software. The problem is when I use the cable it comes with to connect my Laptop to the router and startup the laptop, I get a light on FE0 for about 45sec, then it goes out. Do I have to use a crossover cable for this?

Yes you do
router -> switch = straight thru
switch -> switch = crossover
host -> switch = straight thru
host -> router = crossover

Interesting, why would they not include a crossover cable with the router then? I have a console cable, and a straight thru...
Also when I hook the router up to my switch, it does the same thing, it sees it for about 45sec, then poof its gone.

Oh i wish. You can never find a crossover cable when you need one :-).
I think Cisco assume it will be configured with the console cable and then connected to a switch so they provide a straight-thru.
If you are getting the same when you connect into a switch it's time to use the console cable to see what's happening on the router.

Hi,
You could verify if the port is in "Administratively down" state. If it's the case, you should type the command "no shut" on the fasthernet interface.

The problem is, I do not have a PC available at the moment, that has a com port on it. Those ports are going away :(

OK, I went and got a crossover cable today, still getting the same thing.....

You dont need a crossover cable to connect to 871 Router as the four LAN facing ports are effectively switch ports. The 5th internet facing port F4 is shutdown by default out of the box. please see my post in your other thread.
