I recently received a replacement ADSL2 modem in the hopes that it would work better than the previous ADSL2 modem. It turns out that it doesn't work, either. I.e., neither ADSL2 modem works. My old BroadMax ADSL1 modem is working fine. Postage for returning the first ADSL2 modem was sent and I will be returning it shortly. What should I do with the second ADSL2 modem?
