I have tried to connect HSDPA USB dongle having modem E1750 on router board 951Ui2Hnd and router board RB951Ui2ND with IOS being 6.35.2 but the dongle behaves very abruptly some times both routers detect the dongle and some times they don't. When the routers detect the dongle some times it connects and acquire the desired IP and some times it does not connect at all it seems like the modem gets freezes.
Whereas when i connect HSUPA USB dongle having modem 206 it connects perfectly!
Could someone please help me with this issue??
Re: USB DONGLE WITH MODEM E1750 NOT WORKING
Hi khurram48111,
I have a dongle like you (E1750). It is running on board RB751G-2HnD ROS version 6.36. The current configuration is near to default one:
I am setting default-route-distance=100 because dongle is acting as my backup uplink to the Internet. And port=usb2 has been set automatically, so you can have something else there.
I would suggest you to check firmware revision of your dongle. Old firmware may have bugs causing the problem. This is how it looks for my dongle:
