I have access denied to my 5200

I have access denied when I try to get to things like and

Each time it redirects me to, and I am not sure how to get past this, as I have tried logging in at, under admin//admin, and I am sure it logged in, because I was later able to log out.

I am interested so that I can port forward, and failing that, dmz so that I can play Starcraft comfortably. (I can't host games or even join most :/)

Thanks a lot for any help.

Re: I have access denied to my 5200

I assume you can enter the correct username and password.
if not and you don't have any idea what the password could be other than standard ones like 1234, 0000, admin you got to reset your router.

if you do know your password and username you probably have a high internet security settings and/or problems with accepting cookies. Try adding the address to safe websites in your internet explorer settings.

5200 speedstream blocks my peer to peer sites, mystic island game site, all bittorrent downloads and limewire

Hi Shepherd1880,

First thing:
The computer that you're using for these services needs to have a static IP address configured in your private network and not a DHCP address assigned by the router.

Secondly thing:
Depending on your security policies (computer firewall and/or router), you will need to sure that the settings from your router and/or your PC firewall are not blocking the ports that you need to connect for these services.

Once you know that you have this area covered, you can move forward with the necessary procedures to properly configure your Speedstream 5200 using the link below:

Hope this helps!

Open the following link --

speedstream 5200

Download the manual from the link and review page 7 for ethernet connection.

Notice particularly the back of the device. There are four connection points to plug things in the one on the left with DSL is where cable with the phone connectors connects the phone jack to the speedstream 5200. On the right the round connector with the pin is where the power goes. Next to the power connector to the left is a USB connector. In between usb connector and the DSL port is an ethernet connector. One way to avoid the need for the USB software os to use the ethernet connector bu connecting an ethenet cable (wider connector that fits snugly in both ports one on the Speadstream 5200 and the other probably present on your computer.

USB driver including VISTA (if you prefer)
