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

I bought this unit to install on a home DLNA server in order to play 4K content on a new TV. When you try to install the driver from the disk, Windows 7 crashes into a blue screen. At the office site downloaded the driver marked "First Released", ancient as a mammoth. As it turned out, it lacks support for 8022022ac mode. The official forum is dead, posts from 2022. I contacted technical support, where they gave me a link to a beta version of the driver two years ago, in which there was 8022022ac mode, but the adapter flatly refused to connect to the router in this mode. Further conversation was reduced to the repeated assertion that the problem is in my devices that do not allow this miracle of high technology to work, to which I modestly remarked that I had a top-end Keenetic router, Sony flagship TVs, an Onkyo AV receiver and a Huawei smartphone. And they work beautifully at speeds up to 867 Mbps without a single gap. The answer was enchanting - "Turn them off." Those. do I have to turn off the $500 home theater to let this bauble work alone? In general, by self-picking, I found out the chipset model, downloaded the native driver from the Realtek website (2022, I note) and, finally, connected it at a speed of 867 Mbps at 5 GHz. The joy was premature. The device, the only one in my network, is periodically lost from the visibility zone of the router, and then just as suddenly appears. There is a suspicion that it overheats, the case heats up decently to the touch. In the 2.4 GHz band, the device works stably. But after all, it is declared as one of the fastest on the market! In general, it’s not the spending of some 1500 that upsets, but a week of wasted time and running around with an external HDD from a computer to TV. And, what is especially offensive, this device has a high score on the market and positive reviews from owners who have not exploited it in the 5 GHz band. And it was they who turned me away from buying Asus and Zyxel's proven acquisitions.
