Why can't I connect at 56K?

There may be several reasons for this:

First, the highest connection the FCC allows over standard phone lines is 53.3k. This is the fastest connect rate you can get. If your are connecting in the 40k-50k range, this is considered good for most dial up connections.

If you connect at a rate less than you would like, your modems 56k protocol may not be compatible with ours. We support the fastest and most common protocols, 56k Flex and V.90. You can attempt to update your modem drivers.

The biggest factor in determining connection speed are telephone lines. Age of the telephone lines in your area, "line noise", and weather can all effect your line quality. If you are concerned about the quality of your phone lines, please call you local telephone company. However, keep in mind that the fastest speed the phone companies guarantee is typically 21k.

Lastly, as the technology of modems has advanced they have become less forgiving to phone line noise. Often we see a customer with a new PC and/or modem who suddenly can't connect. This has to do with the fact that the new high-speed modem protocols don't operate on a poor connection and will attempt to downgrade the protocol to something that will accept the conditions. On many new modems the old protocols are not installed because the manufacturers need to save money and keep the cost of the modem down and gamble that you won't need the lesser protocol anyway. So when the switch tries to downgrade the protocol to something that isn't supported on your modem, you are immediately disconnected. Trying an older modem from the same location can sometimes demonstrate this phenomenon and installing an older or more expensive modem with more installed protocols can solve the problem sometimes too. We suggest external hardware modems for the best dial-up connection.
