Correct. The best case throughput of this router is 55 Mbps. As you know, it will also depend on distance and interference. The law of diminishing returns applies when it comes to wireless data rates. You'll need a Rs. 4000 router to get 100 Mbps. Rs. 8000 router to get 125 Mbps and probably a Rs. 15000 router to get 150 Mbps. Actual real life data rates will be less than a third of manufacturer specifications at higher speeds.
Thank you! Final couple of questions:
1) Does the N300 do any better?
2) Is Netgear the way to go? What about TP-Link/D-Link etc?
