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, XP, and Vista
®
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
