Re: lost connection on laptop
If you're having problem with the wireless connection check first if your son's laptop can still detect the network of your router. Right click on the wireless icon on the bottom right hand>click view available wireless network>if network is showing connect to it.

try updating the firmware to the latest version.
it may fix any bugs or wireless issues in the update.
I presume that your internet was working fine before you bought your new laptop. Unless you've done something to change it it should still be working as before.
You shouldn't need a CD - if you think about it you don't need a CD when you log in in Starbucks so why should you need one at home?
The only thing you need to know is the router's wireless name; Talktalk 12345etc, and its password - which is the password your son is using.
I can't explain why you can't connect when your son is connected - as the router should be able to host 253 laptops (very very slowly mind) - unless the router has been set with an access list that only allows his laptop to connect.
Your laptop seems to be hooked to your neighbours unsecured network automatically and it is going online with that. About comcast, when you connect a router to the modem or a computer to the modem, the modem has to be rebooted to give a valid IP to the connected device. If the modem is not rebooted the computer or the router will get 192.168.x.x IP address which is called private IP address.
Sounds like you are setup to use Internet Connection Sharing. don't do this. Have each computer connect to the internet via the router. If the router is wireless connect all computers wirelessly to the router that are wireless capable and any computers that are not wireless capable, connect them to the router via a cat5 cable to the cat5 ports on the router. This will solve your problem. BPCS
