Are all computers connected to the router affected?
If so, try this first:
Unplug the power to the cable / DSL modem
Connect the power to the router.
Connect a computer to one of the LAN ports of the router.
Restart your computer.
Restore the router to factory defaults. Note: This will remove all previously configured settings.
Once the router has gone through the restore it will then begin the reboot. When the reboot completes plug the power back into your modem.
This addresses a common scenario where the router has been connected to the Internet for an extended period and holds an IP address (DHCP lease) for a longer period of time than your Internet Service Provider (ISP) allows.
This is normal and does not indicate any issue with your Belkin router or ISP.
If the router is located where you cannot easily unplug it, you can restart it using the router’s web-based interface. If your DHCP lease time seems to be extremely short, contact your ISP to see if there are other issues on the network.
In certain network scenarios, it may be helpful to turn off all the equipment on your network, and then turn it all back on. Leaving some devices unplugged for up to five minutes can also help. Try unplugging the router, any switches, and any cable or DSL modems. Shut down connected computers. Plug in the cable or DSL modem first.
Plug in the Belkin router second, and wait for the lights to cycle through the startup routine. This prevents another device from taking the DHCP lease. Lastly, start up your computer.
Are just wireless clients affected?
If so, focus on factors that affect wireless clients, such as:
Network selection and security
Hardware access control
Client TCP/IP settings
Sources of interference
Are just wired clients affected?
If so, check your network adapter settings. Check all cable routing, connections, and power supplies.
Can you connect to the Internet directly?
Set up a computer to connect to the Internet directly, without the router.
If you cannot connect to the Internet without the router, please contact your Internet Service Provider for assistance.
Check your signal strength
You may lose your wireless connection if you go beyond the range of the router, or if there is an obstacle between your computer and the router that blocks wireless signals. You can check signal strength by opening your wireless adapter’s interface.
Is your modem configured correctly?
For Windows XP and 2000:
1. Connect your computer to your modem with an Ethernet cable.
2. Click Start, and go to Run.
3. In the Run box, type CMD and click OK.
4. In the DOS window that opens up, type ipconfig and then press Enter on your keyboard.
For Windows Vista/7:
1. Connect your computer to the modem with an Ethernet cable.
2. Click the Start button and in the Start Search box, type cmd. You can either press Enter on your keyboard or click on cmd.exe when it appears in your search list.
3. In the DOS window that opens up, type ipconfig and then press Enter on your keyboard.
4. The IP address (or IPv4) will be a series of numbers following the pattern xxx.xxx.xxx.xxx (for example, 192.168.2.2).
After following either of the steps above, your IP address is 192.168.xxx.xxx, then your modem is also a router and will need to be bridged by your ISP. If your IP address begins with a 169.254, your computer did not receive an IP address from your ISP.
