TP-Link Archer T2U Plus AC600 Wireless Dual Band USB Adapter

This device actually works really well. The wireless is reliable and the setup was flawless for a windows PC. The problem is the design. It is back heavy which makes the connections to the port fail. Makes it seem like it’s on but it isn’t. I have resorted to using something, rubber band or whatever, to make the connection reliable. Once that is in this works well and is worth the money. I recommend to anyone who needs a cheap wireless ac adapter and has a little macgyver in them.

I bought this adapter because the onboard wireless adapter in my laptop was limited to the 2.4 GHz band and I was hoping to increase download speed by switching to the 5 GHz band. The adapter was immediately recognized by Win 10, so setup was a breeze. But when both signal strength and internet speed were significantly lower on both bands than with the onboard 2.4 GHz adapter. On the 2.4 GHz band, signal strength dropped from -53 dB (excellent) to -68 (OK, but not great), and speed dropped from 50 MBps to 25 MBps. Worse yet, strength on the 5 GHz band was -73 (marginal at best) and speed was 10-15 MBps. It's a good thing the price was low. I don't think there's anything inherently wrong with the adapter and suspect that, in other situations (perhaps not so far from ... MoreI bought this adapter because the onboard wireless adapter in my laptop was limited to the 2.4 GHz band and I was hoping to increase download speed by switching to the 5 GHz band.

I purchased two. The first installed very easily and over came the problem that the internal wi-fi had in dropping the signal. This is much improved. Installation was very easy and no issues. Because of that I purchased a second. The installation was not so easy. Can't say as to why but it would not find the device and having found it would not find a router. After getting the latest down load from the web site (used the CD installed software first) it was okay. Again, over the nano dongle used before the Archer T2U Plus with the antenna worked better either with the antenna vertical or horizontal and at the back of the PC. It is 5GHz only so some older routers wont be found.
