He does not have a router according to his other posts.
I did not see that in this thread but maybe you searched other threads by this user.
If this is true we need more info.
Some cable modems and DSL routers will use NAT.
If so it could be this device is failing on these ports.
If this is the case it may be possible to login to the device and change these settings, we (myself or someone else) may be
willing to try to help you with this but this is beyond the scope of this forum.
What is your connection type?
What is the brand/model is the cable modem or DSL router?
You are not using dial up I assume, I know some of the users are.
Is the IP reported by typing "ipconfig /all" at the command prompt [C:>] the same as shows in the port test(Shields Up?)?if these are different we can stop here
and see if we can change the config on the cable modem or DSL router.
I would suggest if you want to troubleshoot further
you post the your CFP config.
You can download the reporting script directly from here
or the forum thread with more info and a privacy warning can be found here .
The changes to the report noted below should get most, if not all, of your sensitive info off the report. If want want to read through it to see what is shown the report could be 30-40 pages or more
If want to delete your Ip address you can do a replace using "Notebook" hit Ctrl+r and type your IP address
i.e. in find box type 192.168.0.23(Your IP reported by "ipconfig /all") & in the replace box type X.X.X.X
However this info may be needed to troubleshoot your problem
also at the top of the report, in the first 2(two) lines under "General Information" you will find your computer user and your computer name, you can delete both of these.
This script makes no changes to computer what so ever. It only reports on some CFPv3 & computer network settings
