We are having a problem with a site that is dropping its internet connection. The Digi WR21 does not list a minimum network speed requirement (it only lists the maximum speed at which it is capable of sending). We suspect that the issue lies with the ASDL modem and not with the Digi (I.e. the modem is going offline). However, is there a (slow) speed at which the WR21 won’t work?
