Friends please help me to know the difference between Linksys WAG54G2 and WAG120N, there is a cost difference of 1000/- between the 2 models. I would like to know what is the main difference between them. I could not find any reference to WAG120N in this form too.How is the failure rate or MTBF of these 2 Linksys modems as I am not able to find any good detailed reviews of either models given above. How is Belkin model F5D7634sa4A in terms of connectivity, failure, and other such parameters.Please help me out with this query or should I go in for BSNL Teracom ADSL wi-fi modem (1600/-)
