First, you need to check if the SlingLinks are providing network connectivity to your Slingbox. You only need to verify if the Slingbox shows solid lights (specially the network light). If not, you will need to check these links.
Once you get the Slingbox network light, you will need to check the security settings (security software) running on your computer. This link will provide you with some information and steps to follow.
Finally, we encourage you to check this link in order to get the step-by-step instructions in order to set up your Slingbox for Internet Viewing.
There are serious connectivity issues. The power light comes on and works fine, but the network light never comes on solid. It blinks a few times sporadically, and the horseshoe light even comes on and blinks sporadically, but the network light never comes on solid. It is plugged directly into the router...no slinglinks involved. The router works fine with every other device in the house, though for good measure we reset it back to its factory settings. I have also done multiple resets, including a "hard reset" per the suggestion from tech support the first time this thing went crazy, but nothing works. I have tried all steps involved in the links you sent me.
If you have not already done so, I suggest that you power down both the Slingbox and the router. Then power up the router only, and program the router to assign the static IP address 192.168.x.254 to the MAC address of the SB (you will find this printed on a label on the bottom of the SB). Your router will typically have the IP address 192.168.x.1, where x might be 0, or 1, or 10, or possibly some other digit. Whatever it is, this will be the number you use for the X in the static IP address to be assigned to the SB.
Next, program your router to forward port 5001 to that static IP address you assigned to the SB.
Then reboot the router and power up the SB, and see if you can rerun the slingbox setup routine.
Good luck, and report back any error messages that your receive.
