[ActionTec] MTU - Size does matter

Recently switched from a cisco modem to an actiontec.

Guess there is an MTU issue with actiontec. Wasn't too pleased with the support I got from CenturyLink.

If you want the gory details, still a pretty short read, here is a link to my adventure

Bottom line, if you notice slowness when using an actiontec modem, lower down the MTU size on your router to 1454.

The issue you had was an improperly defined MTU, not the modem itself. With PPPoE, it's supposed to be 1492.

Many ISPs don't use PPPoE and, therefore, the proper MTU size is 1500, which is what the modem was probably defaulted to.
