I bought a TP-Link Archer T2U AC600 Wireless USB adapter for my media centre upstairs, works fine but will not connect any higher than 150mbps, I've tried changing channels on the router, region/channel on the adapter settings, I have 40Mhz Wide channel enabled, but also tried with 20Mhz, tried just about everything I could find online, new drivers too, but nothing will allow it to connect any higher
It is connected to 5GHz as I have the router set to only output 5Ghz
My Phone (Galaxy S9) connects at 300mbps, so the router is fine, I've tried it on two different machines with the exact same result on both, one is a laptop right next to the router
Updated router firmware to build 36079, previously running 359xx with the same problem

Thanks
This router has 2 radios. But only one works at a time. 2.4. or 5 Ghz. Switch only 5 Ghz band, leave 2,4 disabled _________________ [Ramips] Nexx WT3020F Openwrt @kernel #4.14.167 (OpenVPN server, Wireguard server, AD blocking, SQM QOS, USB)

The router says 450mpbs for 5GHz too
Thats max for this router. 433 mbps on 5 Ghz to be exact _________________ [Ramips] Nexx WT3020F Openwrt @kernel #4.14.167 (OpenVPN server, Wireguard server, AD blocking, SQM QOS, USB)

Yes, which is why I am asking why my 5GHz USB adapter is only connecting at 150 when other devices connect at 300 _________________ TPLINK TL-WR2543ND (5GHz)

Your "other" devices should connect at 433. Disable 2,4 band on your router _________________ [Ramips] Nexx WT3020F Openwrt @kernel #4.14.167 (OpenVPN server, Wireguard server, AD blocking, SQM QOS, USB)

lol, are you reading any of this thread, including what you have already said?
You said yourself my router is only single band, therefore if it is already set to output 5GHz, then 2.4GHz is already disabled...
My router is only outputting 5GHz WiFi
Other devices are connecting at 300mbps
USB adapter is only connecting at 150mbps
Why is USB adapter only connecting at 150mbps? _________________ TPLINK TL-WR2543ND (5GHz)

150 is max. with a single stream client (one antenna).
So this 5GHz @ 433mbps is only AC mode, not N, that's pretty sucky, I'm guessing the S9 has more than one antenna then allowing twice the connection rate
It staets on the box that this is capable of 433mbps @ 5GHz, the website says only AC can do this, but it would still only be a single antenna client right?
So how can AC get 433 when N can only get 150 with the same number of antennas?
Thanks I`ll have a read through, not used AC yet so it seems there is much to learn
Well it cured my problem i was having with 2.4GHz and crowded channels, so it's working for what I need it to anyway _________________ TPLINK TL-WR2543ND (5GHz)

I do not know how you determine actual speed. WIFI sweetspots claims around 130Mb/s while iperf says 92Mb/s to android, and dd-wrt speedchecker claims 28Mb/s to my really old 32bit laptop running Kubuntu. This is to the wzr-hp-ag300h connected to 5GHz. So I would take 150 happily and wish for more.
I copy large single files from my NAS to my media centre to check local wifi speed _________________ TPLINK TL-WR2543ND (5GHz)
