Don't judge too quickly! Go to Dialup Networking Properties/General/Configure/Maximum Speed=? Some isp's require you to downgrade the top speeds to match their end. Also see:Connection/Advanced/Extra Settings=? Some modems & some isp's require a code string to be typed in here. It varies by modem and isp. Also go to: Server Types/Allowed Network Protocols=? Just check TCP/IP for internet use. Other boxes should be nulled. Also see if the TCP/IP settings are identical between the two modems you are comparing. Then MAYBE make a judgement call.
