ohk..to tell u .mostly there are no hubs for MTNL triband users. cauz its not the same LAN technology which some other ISP's like sify and exatt net use..
alos even if there are hubs for triband users u wont get any speed in mbps and all. what u will get is u r normal internet speed.
so i suggest instead of using dc++ on Triband u better try some other p2p software like .torrents..
