Fedora 9 Connecting Problem with Reliance ZTE MG880 and Huawei EC325 modems

[eCubeH]

I had both ZTE MG880 and Huawei EC325 modems working with Fedora Core 6. Service provider Reliance, India.

I just upgraded to Fedora 9.

When I try to connect through either modem, it seems the connection is made (Ping) but pppd issues some garbage and Firefox is unable to recognize the connection. The issue seems similar in both cases. Below is some output.
