Debian Testing yes then no, Mepis is back

I tried for months to use debian testing. Somewhere along the track the team made some sort of error with the kernel or its modules. On a sytem which had wireless, ethernet and modem working, after an update the wireless and modem stopped working. I searched for answers, couldn't get one which worked so I installed latest 32 bit mepis. Mepis works fine. Pity, would have preferred to stay with debian.
