has anyone had their modem speed drop when the 522 is hooked up on the same phone line,kinda wierd having 34500bps when the 522 is unplugged from phone jack and when it is hooked back up and i go and sign on to my isp ,my spped drops to 17300.tried this over an over to see if this was my connection or if was my imagination....but to no avail...the 522 modem must be feeding back or somthing ?...any ideas or thoughts on this matter.
