A user experiencing a slow data transfer problem or internet connection issue in the routerlogin.net network is recommended to connect to the technical support team of the NETGEAR. If secure websites like MSN portal and Yahoo email are unable to access and you are experiencing severe performance issues, it may be because of an inappropriate MTU set in the router. The best MTU setting for a Netgear router is often a default value but sometimes changing the MTU may resolve the network and other severe issues.
