If you are having a problem sending or receiving e-mail, 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...

we’re working with (1452+28=1480). 
Once you find your MTU, you can now configure...
