Had to replace old box in the basement with this unit. It shows the wrong time (EST) and the wrong temperature outside. It does not show the channels I subscribe to and can get upstairs on my gateway. Its pretty much useless to me the way it is. You just should have given me another portal.
Could be that the 3510 was not correctly provisioned on your account. If you want a portal you could look for a used one on marketplace or Kijiji.
Also, beware of purchasing any PVR or portal or remote-box through any "miscellaneous for sale" web-site.
You may be paying the seller for a box that is a "rental" that the seller did not return to Shaw. It is possible that Shaw will refuse to activate it, or will activate it as a $5/month rental. Be sure to get the serial-number, and ask Shaw to verify it with Shaw. Note that if the serial-number is still attached to some person's Shaw account, the Shaw Agent will cite "privacy", and will not tell you about the rented/purchased status, without the permission of the seller to release that information. I recommend that you avoid such "grey-market" hardware.
