Internet Connection Issues

Ok here we go, problem:

My fiance' has an Acer Aspire 5810T (old but still usable) Well it hasn't seen much use since we moved IPSs from Verizon to Comcast. Recently installed Windows 7 to said Acer (because 8 bogged it down) Anyway the problem I am having is this:

I can connect through our home Wi-Fi network, but not the internet. Tried several fixes, nothing!!! But it does connect through XFINITY's Hot Spot (weird huh). All other devices have no problem just the Notebook! Anyway I was doing a bit of trouble shooting and for the sheer hell of it I hooked up an old Netgear Router and wanted to see what that would do! Guess what? the Notebook connected to it's Wi-Fi signal (and INTERNET) with no problem! (Confused!!!) So I am using this old router (hooked to the same Comcast Modem) so that my Fiance' can get on the internet!!

Please for the love of God tell me what I am doing wrong !!! lol



ISP: Xfinity/Comcast
Router/Modem: Arris TG1682G
Notebook: Acer Aspire 5810T
Operating System: Windows 7 Ultimate

Older Router: Netgear WGR614v10

To get more help if you could do "ipconfig /all"(delete the quotes) for the one that does and the one that does not work one of us might be able to help.
