Wireless-G Router WGR614v10 Reference Manual
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. Table
Table 5-1. Common MTU Sizes
MTU | Application |
|
|
1500 | The largest Ethernet packet size and the default value. This is the typical setting for non- |
| PPPoE, |

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 technologies such as ADSL2+ and Fiber to the Home (FTTH) will increase the connection speed to tens of Mbps.
