I have a BSNL Type -2 WA3002G4 ADSL Modem which has been giving me all sorts of problems , the biggest of which has been very poor Wifi coverage. I am looking for a good alternative , which can give me the best coverage possible. My budget is go upto 5k.I assume the modem can be connected in bridge mode and the wireless router can take care of all authentication details. Could anyone suggest a few good options? How about the D-Link DSL-2320B ADSL2+ DSL Modem and the Cisco-Linksys WRT54GL Wireless-G Broadband Router ?
