A friend asked me to take a look at their computer which is having problems connecting to the Internet. It’s a RCA cable modem connected to a Linksys wireless router connected to a WinXP SP3 laptop. After some experimentation, I found:
- Plugging the laptop directly into the cable modem results in an in Internet connection.
- When the router is connected to the cable modem instead, the router can successfully ping Internet addresses.
- When the computer is connected to the router, whether wired or wirelessly, there is no ping response from anything except for the router and itself.
- The laptop can reach the router’s admin website (i.e. 192.168.1.1).
- The router’s admin website can remotely be accessed (I had a friend who’s a little more experienced with Linksys routers connect to it as a test).
- Plugging the computer directly into my router results in an immediate Internet connection… but it’s a D-Link.
Any ideas why the laptop can’t reach the Internet when connected to the router, when the router itself can reach it?
