USB ADSL modem does not work after upgrade to 9.1

Asked by Dave O

I recently allowed Ubuntu to upgrade itself to 9.1 -- after the upgrade my USB ADSL modem was no longer working -- it didn't even power up following a boot (like the system did not know it was there). After several failed attempts, I rebooted using an earlier(?) version of the 9.1 kernal that was listed as an option during the booting process. This allowed the modem to be detected and communicate.

I went back to the "newer" version of the kernal and attempted to reinstall UbuDSL (applet); which is what I use to connect with the modem. I got an error message to the effect the program was not supported.

I am a new user of Ubuntu so, really unsure of where to begin...

Connectivity to the Internet is very important to me -- and I'd like to understand how to fix this and prevent it in the future. Thank you.

I have the same problem with ZTE ZXDSL 852 ADSL modem.

I figured out a way to run ubudsl in Ubuntu. by doing the steps mentioned in the link below.

But still my modem is not synchronizing. I found some one has posted that Version 1 of ZTE ZXDSL works in that way see the 17th post.

Can you help with this problem?
