Router mode: Change the MTU size
If the access point/router is in router mode, you can change the maximum transmission
The 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.
The best MTU setting for router 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 the ISP 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.
