Netgear Nighthawk Router Dropping Internet Connection

Despite bad reviews, I have decided to purchase the “Netgear Nighthawk(R) X4S R7800″ router because of Netgear’s reputation and great history of making excellent networking devices.
Once the router received I found my self in the same situation faced by the other users who bought this router. So, my techie mind started searching for solutions. After searching for half an hour finally found a solution that actually works and would really happy to share the solution with you people.
Please follow the below-given steps as mentioned to resolve the issue.

What is PON Device?

A passive optical network (PON) is a fiber-optic telecommunications technology for delivering broadband network access to end-customers. Its architecture implements a point-to-multipoint topology, in which a single optical fiber serves multiple endpoints by using unpowered (passive) fiber optic splitters to divide the fiber bandwidth among multiple access points. Passive optical networks are often referred to as the “last mile” between an Internet service provider (ISP) and its customers.

First:

First of all, you need to login to the router using its IP Address. By default Netgear IP is 192.168.1.1, In my case, it is 10.0.0.1.

However, If you don’t know the user name and password of your router then you need to reset it using the below-given method.

We need to use a pointed object such as a pen or a paper clip to press and hold the Restore Factory Settings button, located on the bottom of the router, for over five seconds until the Power LED blinks amber.
Release the Restore Factory Settings button, and wait for the router to reboot.

Second:

Once you login to the router, then click on advanced and navigate to setup.

Third:

After that, navigate to WAN setup and from here make a small change in MTU size. i.e Change the MTU size to 1400, and that’s all save the settings.

Now, you can reboot the router and start using it with no issues.

What is MTU?

In computer networking, the maximum transmission unit (MTU) is the size of the largest protocol data unit (PDU) that can be communicated in a single network-layer transaction. The MTU relates to but is not identical to the maximum frame size that can be transported on the data link layer, e.g. Ethernet frame.

Larger MTU is associated with reduced overhead. Smaller MTU values can reduce network delay. In many cases, MTU is dependent on underlying network capabilities and must be adjusted manually or automatically so as to not exceed these capabilities. MTU parameters may appear in association with a communications interface or standard. Some systems may decide MTU at connect time.
