In July I purchased Airtel ADSL2+ Wifi Modem - Beetel 450TC1. However due to 2 weeks of downtime, I recently switched to ACT Broadband 5 MBPS plan. Now the modem is useless for me. Any idea where I can sell it off? It has 1 year warranty and I have the original bill (Dated July 2011).By the way, I am based out of Bangalore, if that matters.
