Hi. I recently bought and installed a 2925n with very few issues . I tested the USB 3G facility using an old borrowed Huawei E172 modem on Vodafone and all was good . I have just received a new ZTE MF730M on Three and I naively thought I could just swap the modems, but the mew modem refuses to connect even when I select it as online permanently . Are there any known compatibility issues and/or changes to the modem initialisation that I need to perform to get this working.

Thanks
Chris

Got the Same Issue, ZTE MF730M with Draytek 2830. Did you find a resolution?

1) When the 3G stick is plugged into the router just keeps restarting.
