Review on Enhance Internet Speed with TP-Link AC1200 Wireless Dual Band USB Adapter (Archer T4U V1) by Devarajan Devarajan ᠌

The first month everything was great. I put it on a new computer, the device worked like a clock. In the second month, connection failures to the 5 Hz network began. "Failed to connect to the network." Looked through the Internet - the problem is common. Two days in the evening after work, I conjured with ports and the region in the router settings to get connected. Now there is channel 48, the US region. Phew, it worked. If not for these problems, I would put a solid five. 2.4 Hz works without interruption.
