When prompted for a user name enter: Line Test Why can't I connect at K56Flex or V.90 rates? - Courtesy of Zoltrix - The most common barrier to 56k performance, is the presence of a SLC96 (slick) concentrator in your neighborhood. Telephone companies install a SLC96 to split up lines in existing phone hubs to add more lines in high-growth areas. This split nullifies the 56k capability, dropping all lines down to a maximum V.34 specification. A second barrier occurs when a phone line is stretched beyond 18,000 feet from a telephone company office, which is beyond the effective range of the 56k technology. This occurs primarily in rural areas. Corporate offices that are using PBX systems will lose 56k capabilities due to line attenuation. Check with the phone company to see if the above applies in your situation. Another cause could also be the connectors and wiring in your house. Following is from a user of a K56Flex Zoltrix modem. Like alot of us I also was having trouble with the 56k! I have both the 56k access lines from my ISP and a 56k modem! But usually I would only connect at 21,600 (sometime 44,000 bps if I was Lucky) My average speed only being 17,000 bps! My high was 27,000 bps and my low was 500 bps! I also kept getting error messages! If you are like me, you thought the Telephone Company had bad wires! But then I thought about my house's plugs (I have a Old house with Old jacks)! So I cleaned the connecter pins on all the cords I was using, I cleaned the Jack's connecter pins I was plugged into and the Wire inside the jack! I cleaned them with a fluid that cleans connector pins! (aka video game cleaner!) I cleaned everything until it turned from a dark green to a Bright Brass-e Color. And WOW! I connect at 50,000 bps sometimes and get no errors. My speeds are great with 37,000 bps being my average 28,000bps being my lowest and 50,000bps is my highest! What a Great improvement!
