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).
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, Vista®, and 7 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
