To troubleshoot a Netgear wireless router, check that the device is being used within range and that there are no metal objects or large objects obstructing the signal; if nothing has changed in this regard, try disconnecting other devices from the Internet as they might be using up too much of the router's bandwidth. Finally, check antennas, check the settings of the router, change the channel and lower the router's speed.
If those main fixes fail, try the following:
- Check antennas and interference Either turn off other devices that use wireless signals, or move them away from the wireless router as they might be causing interference. This includes things like cordless telephones and baby monitors. Adjusting the angle of the antenna can also work in some situations. Some cable modems can cause interference. If there is a cable modem move it at least 3 feet away from the Netgear router.
- Access the settings Changing the settings can fix the problem. To access the router's settings, go to a computer, open a browser and type 192.168.1.1 or 192.168.0.1 into the address field. The default username is "admin" and the password is "password."
- Change the channel Once logged in, the first thing to check is the channel. Go to Wireless Settings and change it to a different option to check to see if that improves the problem.
- Lower the speed If changing the channel doesn't work, go to Mode and lower the connection speed.
- Change advanced setting If this still does not work, there is one more thing to try. Go to Advanced then Wireless Settings. Change the setting for both Fragmentation Length and CTS/RTS Threshold to 2304.
