DSL line quality - speed problem

Level 1

Hi guys,

 

Just a easy question, my dsl plan should offer me a 24mbit connect but my Cisco 1801 only syncs at 11mbit.

the provider told me i live to far from the dslam. But when i check my dsl status my attenuation is 22db that should be enough to have a higher download speed right?

The lower the attenuation the better and the higher the noise the better signal

Your noise level is very low

6dB or below is bad and will experience no synch or intermittent synch problems
7dB-10dB is fair but does not leave much room for variances in conditions
11dB-20dB is good with no synch problems
20dB-28dB is excellent
29dB or above is outstanding
