Netgear WNR1000v3h2 사용자 설명서

An incorrect MTU setting can cause Internet communication 

problems such as the inability to access certain Web sites, frames 
within Web sites, secure login pages, or FTP or POP servers.

If you suspect an MTU problem, a common solution is to change the MTU size to 1400. If you 
are willing to experiment, you can gradually reduce the MTU size from the maximum value of 
1500 until the problem goes away. 

1500

The largest Ethernet packet size and the default value. This is the typical setting for 
non-PPPoE, non-VPN connections, and is the default value for NETGEAR routers, 
adapters, and switches.

1492

Used in PPPoE environments.

1472

Maximum size to use for pinging. (Larger packets are fragmented.)

1468

Used in some DHCP environments.

1460

Usable by AOL if you do not have large e-mail attachments, for example.

1436

Used in PPTP environments or with VPN.

1400

In the main menu, under Advanced, select WAN Setup. 

In the MTU Size field, enter a new size between 64 and 1500.

Overview of Home and Small Office Networking 
Technologies

Common connection types and their speed and security considerations are:

Broadband Internet. Your Internet connection speed is determined by your modem type, 

such as ADSL or cable modem, as well as the connection speed of the sites to which you 
connect, and general Internet traffic. ADSL and cable modem connections are 
asymmetrical, meaning they have a lower data rate to the Internet (upstream) than from 
the Internet (downstream). Keep in mind that when you connect to another site that also 
has an asymmetrical connection, the data rate between your sites is limited by each 
side’s upstream data rate. A typical residential ADSL or cable modem connection 
provides a downstream throughput of about 1 to 3 megabits per second (Mbps). Newer
