|Which ISP is he connecting to ? |
Does he have a standalone router, with a standalone high speed modem connected to it,
or a router / high speed modem combo, or just a standalone high speed modem ??
If he has a standalone high speed modem, can it be connected via either a USB or a network cable connection ?
If so, which is it connected by ?
Is the high speed modem DSL, or ADSL,
or coax cable
or coax cable / satellite ?
For some DSL or ADSL connections, the ISP requires that there be the MAC address of a network adapter registered with a web site of theirs. That's normally done by running installation software provided by the ISP, but you may be able to access only a certain web page to do that as well. If that hasn't been done, or if the MAC address detected by the ISP is not one that was registered, you can't access the internet via that ISP. Some allow only one MAC address to be registered, some allow a small number of them more than one.
(E.g. Telus allows two MAC addresses to be registered.)
If a MAC address was registered when the standalone high speed modem or combo router / modem was connected, then you change the network adapter you're using to connect to the standalone modem, or change the router / modem combo, or change the standalone router, either...
- you must register the MAC address of the changed device
- or - if there is a router between the computer and the internet, you must either ....
- clone the MAC address of a network adapter that has already been registered, in the router's configuration settings,
- or - type in manually the MAC address of a network adapter that has already been registered, in the router's configuration settings.
- or - type in the MAC address of the original router /modem combo that has been registered.
Routers have their own MAC address, but that can be over-ridden by cloning another MAC address of a single network adapter that's connected to the router at the time, or by manually typing a MAC address - the ISP detects whatever MAC address the router allows it to see.
