My Modem cannot connect at 56k
The highest connection speed with 56k modems is 53kbps due to the FCC guidelines. If you are connecting at 53kbps or close to 53kbps, this is the highest connection speed that your phone lines and modem will support.
If you are not connecting close to 56kbps, you need to ensure that your Internet provider is using the same standard, such as X2, Flex, or V.90. If you are not connecting to the same standard, you will connect at a max of 28 or 36kbps.
If your Internet Service Provider is using the same standard, it is a good possibility that your phone lines may not be compatible or that your phone lines are not being switched properly.
