Position Your Modem Router
The modem router lets you access your network anywhere within the operating range
of your WiFi network. However, the operating distance or range of your WiFi connection
can vary significantly depending on the physical placement of your modem router. For
example, the thickness and number of walls the WiFi signal passes through can limit
the range.
Additionally, other WiFi access points in and around your home might affect your
modem router’s signal. WiFi access points are modem routers, repeaters, WiFi range
extenders, and any other device that emits a WiFi signal for network access.

Change the MTU Size
The maximum transmission unit (MTU) is the largest data packet a network device
transmits. When one network device communicates across the Internet with another,
the data packets travel through many devices along the way. If a device in the data path
uses a lower MTU setting than the other devices, the data packets must be split or
“fragmented” to accommodate the device with the smallest MTU.
User Manual21Specify Your Internet Settings
Nighthawk AX8 AX6000 WiFI Cable Modem Router Model CAX80
The best MTU setting for NETGEAR equipment is often the default value. In some
situations, changing the value fixes one problem but causes another. Leave the MTU
unchanged unless one of these situations occurs:
You experience problems connecting to your ISP or other Internet service, and the
•
technical support of either the ISP or NETGEAR recommends changing the MTU
setting. These web-based applications might require an MTU change:
-
A secure website that does not open, or displays only part of a web page
-Yahoo email
-MSN portal
You use VPN and experience severe performance problems.
•
You used a program to optimize MTU for performance reasons, and now you are
•
experiencing connectivity or performance problems.
Note: An incorrect MTU setting can cause Internet communication problems. For
example, you might not be able to access certain websites, frames within websites,
secure login pages, or FTP or POP servers.
To change the MTU size:
1.
Launch a web browser from a computer or mobile device that is connected to the
modem router network.
2.
Enter http://routerlogin.net or 192.168.1.1.
A login window opens.
3. Enter the modem router user name and password.
The user name is admin. The default password is password. The user name and
password are case-sensitive.
The BASIC Home page displays.
4. Select ADVANCED > Setup > WAN Setup.
5.
In the MTU Size field, enter a value from 64 to 1500.
6. Click the Apply button.
Your settings are saved.
If you suspect an MTU problem, a common solution is to change the MTU to 1400. If
you are willing to experiment, you can gradually reduce the MTU from the maximum
value of 1500 until the problem goes away. The following table describes common MTU
sizes and applications.
