Region : Argentina

Model : TL-R470T+

Hardware Version : V3

Firmware Version :

ISP :


I just got this router, thinking that it being enterprise class and all it will perform better than my trusty DIR-615. To my surprise it cannot even handle properly two P2P clients running on my LAN. One client alone is capable of using up my 50 mbit/s bandwidth, but as soon as the second client starts on a different machine everything goes downhill - combined throughput drops to less than 20 mbit/s, WAN packets get lost etc. Is this really beyond the abilities of R480T+ or am i doing something wrong? Is there and alternative firmware I can try? I'm not even able to find the hardware specs on V2 - any pointers here?

Thanks!
