i know both FW on both computers have unpnp enabled, my router also automatically set UNPNP set to on. i dont know where to check windows 7 or my modem though...i dont think i can set my modem to allow but, but like said i had no problem before when i just had the modem, so i dont think it should matter, but where do i go to check windows 7 unpnp?

I use XP Pro so I can't help with Win 7, I suggest you use your Windows help facility that should tell you how to enable UPnP on your O/S.

As for your modem, you have not mentioned the name or model so I can't really say anything about it.

Finally, you said:If your modem has UPnP, and you should check, then you should switch it on because UPnP was developed to enable software and hardware from different manufacturers to work together. By inserting a router in your set up you have introduce a piece of equipment that is running several technologies at the same time and so causing the problem you are getting.

Therefore, theoretically, if everything in your set up is running UPnP then your chain of equipment (hardware and software) should run seamlessly.

UPnP is not a totally reliable technology either. Even with same model of device with UPnP, some people's UPnP gives problems whereas for others does not. Also often devices are made by different manufacturers but sold under the same company label. The implementations of UPnP may differ or something else in it's operation varies to others.

Example of devices made by different manufacturers: ATI video cards are often manufactured by up to 10 different manufacturing companies with variations between each ones operation abilities, performance & reliabilities.
Linksys are a modem/router company that has several manufacturers. Some other modem/router companies do this also. Also, some devices are customised for a particular ISP.

LOTR (and Dubbin)

Your posting on UPnP not being totally reliable is true and manufacturers seem to implement it in a somewhat hap hazard manner. However, I did not want to add to Dubbin's confusion by revealing this bit of information without him trying it out first.

Remember, if it works on his set up then his problems are solved, if it doesn't work then his only course of action is port forwarding.

You know, I still remember from five or so years ago when I had to port forward my first modem router, I went grey and then bald from the experience , until Wondering Why came to my rescue.

So rather than put Dubbin through the same pain, I would suggest and encourage him to try UPnP first before anything else.
