I believe that Suse Yast2 selects the modem kernel driver settings from the modem module.Let's try two things:1) Try it manually:root@linux:/# wvdial -C /etc/wvdial.confroot@linux:/# ifconfig ppp0A similar output should be displayed:ppp0 Link encap:Point-to-Point Protocol inet addr:10.69.60.203 P-t-P:192.168.254.254 Mask:255.255.255.255UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1RX packets:4 errors:0 dropped:0 overruns:0 frame:0TX packets:5 errors:0 dropped:0 overruns:0 carrier:0collisions:0 txqueuelen:3 RX bytes:64 (64.0 b) TX bytes:97 (97.0 b)Does that look like what you manually designated?Alternate Solution: You can start your modem automatically and bypass Yast2 by adding your startup string directly to /etc/rc.local at boot:/usr/sbin/wvdial -C /etc/wvdial.conf[make sure that's the correct path]2) Verify your settings in Yast2Yast modem configuration documentation:In the YaST Control Center, access the modem configuration with Network Devices > Modem. If your modem was not automatically detected, open the dialog for manual configuration by clicking Add. In the dialog that opens, enter the interface to which the modem is connected for Modem Device. Configure supported CDMA and GPRS modems with the YaST modem module just as you would configure regular modems.From:
http://www.novell.com/documentation/sles10/sles_admin/index.html?page=/documentation/sles10/sles_admin/data/sec_basicnet_yast.htmlIt's a fairly good bet that your settings are being passed to the modem, but the kernel driver and modem itself is not compatible with those settings.You say that these were the same in XP? I am not understanding... Did you recently rebuild this server? Are you running a liveCd or comparing the modem as initialized in another computer?Also, what is your process to compare your download and throughput time, just out of curiosity? BUT THE BIG QUESTION is whether this is a WINMODEM or not? It's always worth doing a quick two page google of:1) Your MODEM device manufacturer and model.2) Your distro version.3) Any error - in this case MTU..Some modems have specific anomolies based on known hardware limitations of the specification, kernel driver issues, and distro (just like ethernet, graphics cards, etc).Use the Source, young Jedi!
