Try to link at maximum speed with 5GHz 802.11AC Test EDUP USB3.0 adapter 1200Mbps Need MediaTek driver 5.1.21.0 at least to enable 5GHz range. Maximum link is 144Mbps... Need to test with Intel 7260 wireless-AC replaced this, 7260HMW 174Mbps only... sad bad result with this TP-LINK router model , buy another hardware |
