Worked a lot with the older 3g USB modems with the Cisco SRP router lines. Never had an issue. Enter the uml290vw which showed up on the compatibility list this January. Had a client get one. Plugs in, the SRP recognizes it but never dials in the auto mode where this just worked with the 3g modems. You can put the srp in manual setup mode but other than the dial number which I assume is still #777 no idea what to configure for the APN, username and password. Anyone been able to get this modem to work with the Cisco SRP routers?
