Some cable ISPs only connect to a specific MAC address (each piece of
hardware has its own MAC address). Sometimes, this is fixed as the MAC
address of the first PC to successfully connect -- in which case you
have to call the ISP to reset your connection if you change equipment.
Other times -- and it looks as if this is your case -- turning off the
modem briefly allows the connection to reset.
If this is the case, I'm not sure why your router wasn't recognized if
you had turned the modem off for several minutes before connecting the
router. Are you sure you configured the router correctly otherwise?
However, many routers have a feature that permits them to "clone" the
MAC address so that they appear to be the original PC. Try this.
Connect with your PC. Make sure that you really are connected to the
Internet. Open a command prompt window (start > run > cmd [click OK])
In the command prompt window that opens up, type
"ipconfig /all" [without quotes] [press enter]
Among other things, you should see a line like this:
Physical Address. . . . . . . . . : 00-10-DC-D2-77-F2
That is the physical address (or MAC address) of your computer. Write
it down.
Now, read the manual for your router, learn how to clone its MAC
address, and set the router's MAC address to the MAC address that you
wrote down. Configure the remainder of your router's WAN connection
entries appropriately. The router should now connect to the Internet
and you should be able to connect both computers to the router and get
to the Internet.
If you have problems, be sure to include the make and model of your
router in your next post.
