My airtel connection is horrendous. I cannot remain connected for more than a few minutes at a time.SNR varies from 6 to 12(Downstream), and every 2-3 minutes the modem disconnects (450BX).I have complained many times, and every time the same idiot comes, and he tells me that apartment building wiring is old, so nothing can be done.So should I call up airtel and ask them to disconnect. Will the retention department change our apartment wiring?Since I am in noida, my only other option is BSNL, which can turn out to be worse. So if I do get rid of airtel, is MTNL data card (1650/month unlimited) a good option? I will be happy if I can get around 200 KBps for this price (approx 1.6mbps)
