3. Why can’t I connect to certain sites or send and receive emails when connecting through my router?

If you are having a problem sending or receiving email, or connecting to secure sites such as eBay, banking sites, and

Hotmail, we suggest lowering the MTU in increments of ten (Ex. 1492, 1482, 1472, etc).

Note: AOL DSL+ users must use MTU of 1400.

To find the proper MTU Size, you’ll have to do a special ping of the destination you’re trying to go to. A destination

could be another computer, or a URL.

• Click on

Start and then click Run.

• Windows

95, 98, and Me users type in

command (Windows

NT, 2000, and XP users type in

cmd) and

press

Enter (or click OK).

• Once the window opens, you’ll need to do a special ping. Use the following syntax:

ping [url] [-f] [-l] [MTU value]

Example:

ping yahoo.com -f -l 1472
