This article contains detailed information about troubleshooting of wireless LAN router for several issues. In the Netgear router setup procedure via routerlogin, there are often some manuals that do not involve problems and failures, but some issues become difficult to cope and cannot be solved without adequate knowledge.
Below, we have analyzed the typical faults caused by routers in the wireless network and has provided the various solutions accordingly. There are many reasons for the connection failure of the wrong line. Let’s start with the basic troubleshooting first.

Basic troubleshooting starts here:
The first thing to check is whether there is an error in the connection configuration. Check the broadband access terminal first to ensure that the power of the router is normal. The indicator light on the router can indicate whether the broadband line access terminal is normal. It can be identified manually by noticing the broadband access terminal and the user terminal lights.
•    Observe the light; the continuous blinking is normal, not bright or long. However, if the light does not flash, check to see if the router is placed too far away from the receiving computer or if there is a large obstacle in the middle.

•    In any of the above-given situations, please re-position the router so that the wireless router and the receiving computer do not have too many obstacles, and the receiving computer can be within the signal transmission range of the wireless router.

•    Checking the wireless card is also essential, you can replace the card and reinstall the driver for debugging, then card, click "wireless connection View Available "refresh" network list after the set card parameters, and then view in  "Properties" that whether there are data transmission and reception, if not then start troubleshooting using the below means.

•    Of course, the hardware failure of the router itself is also the direct cause of the connection failure, but this is not the scope we can solve. It should be contacted by the http://www.routerilogin.net/ for repair or replacement. Improper setup can't connect to "Settings" can be divided into two aspects: computer settings and router settings.

Advance Troubleshooting – Checking the router’s settings.
Advance troubleshooting start here, click into the " My Network Places " properties, open the " Wi-Fi " , then set the "IP address" "subnet mask " and " gateway " , as long as the computer's IP address and the wireless router IP address In the same network segment. The setting of "Gateway" can be found in the description of the network card.

•    Generally, it is the same as the IP address of the router. The settings of the router are relatively professional and complicated. First enter the Netgear router default IP in the system browser, enter the administrator login name and password of the router in the login interface that pops up to enter the setting interface.

•    If you’re unable to login to your router’s settings portal, in this case, you need to check whether the broadband account and password, given by the network service provider are correct. If it is incorrect, try to connect after correcting it. If you still can't open the page after connecting, contact Netgear router troubleshooting team.

•    Other problems exist in some old wireless routers is when we configure the advanced function options of the router, some of the functions cannot be used when repeatedly confirming that the connection is correct. At this time, you the first thought should be to check whether the hardware is faulty, and if it is not then, you need to check the version of the router system using the Netgear router default login.

•     Consulting the wireless router manual, see if the function supports this version of the router system. Router systems usually have many versions, each supporting different features. If your current software version does not support this feature, you should find the appropriate software and upgrade it first.

Given below are the steps for firmware/system update of your router:
•    Click to enter the "System Tools" option of the wireless router, and then select "Software Upgrade ".
•    At this time, the current software version and hardware version will be displayed in the dialog interface.
•    Enter the "filename" in the pop-up dialog box (i.e. the system) Upgrade the file name) and "TFTP Server IP" and click "Upgrade".



Pay attention to the upgrade
Select the software that is consistent with the current hardware version to upgrade. Do not turn off the power of the router during the upgrade process. Otherwise, the router will be damaged and cannot be used. In the case of stable network, the Netgear router firmware upgrade process is very short.

It will take more than a minute. When you find that the router restarts after the upgrade is complete, don't worry that this is normal. After the general upgrade, the router will work more stable and add some new features for this version.
