I have a Samsung SMT-G3010 and Arcadyan ARV752DPW. Both don't run OpenWrt and I use them primarily as a modem for an ALIX.2. However, they consume a lot of power compared to my older Sagem USB modem (the ISP wasn't able to change back to ADSL after I changed contracts) and don't allow direct congestion control. I did some research and found no ADSL2+ USB modems. Has somebody some recommendation what to do in this case?
