troubleshooting a network is a multiple step process.
1. Establish that your modem is working properly, and plugged in. As per the diagram shown here
- Your "Cable link" light should be on (signifying that the outside cable is properly connected to the router)
- Your "Internet" light should be on (signifying you have an established Internet connection)
- And, most importantly, your "PC Link" light should be on (showing that at least as far as the modem is concerned, it is detecting that the computer is plugged in to it.
double check to make sure that the network cables are seated properly, and plugged in all the way. the PC link light should give you an indication for modem-side- the LED light around the network cable jack on the laptop should give you an indication PC-side.
check on your laptop for any security software that may restrict new networks from being detected and disable them to test. For example, Symantec or Mcaffee Firewall can sometimes block a "new" network from being detected.
Completely shut down the laptop and unplug the power cord from the modem. Plug the modem back in. Wait around 3 minutes for the modem to initialize and do it's thing- then turn on your laptop and see if this resolved your issue.
If this doesn't work, you may want to try other things, such as resetting your network
, and removing/re-installing your network adapter drivers.
