Will "TP-LINK TL-WR841N 300Mbps Wireless N Router" support 60 Mbps connection?

You can use on ACT and you will get full 60Mbps speed.

Please note that, speed on wifi depends on factors like range, other wifi networks around you, channel it is beaming on etc but you should be able to get 60Mbps speed with this router.
