hi
i'm using archer t9uh wireless adapter and archer c9 router.
but both of my download and upload speed can only achieve around 200mbps. upload speed has no issue as the unifi 800mbps only provide 200mbps upload speed.
tested ethernet cable with the same pc, can achieve 800mbps download speed.

i have no idea where is the problem coming from. i placed my wireless adapter under my router, which is put on top of the shelf, short distance in between. plugged into usb3.0 port as well.

after reading post on earlier page,
even stock tm unifi ac1200 is achieving 200mbps for 300mbps package. it seems impossible for 800mbps package and ac1900 user to achieve above 200mbps.

Seen your other post. Did you consider trying with another router?
I am assuming you are using 5GHz AC? Set it to any channel above 130 and to 80MHz, and see if that helps.

highest channel is 48.
set to channel 48, 80mhz, ac only. still the same.
is that possible arising from bandwidth limit of the wifi? but i couldnt find the setting to adjust the bandwidth for my tplink c9

any problems with the setting below? everything is in default

Hi, try to set to the lowest channel. Or set Auto and see got differences or not.

Is NAT Boost Enabled?

Thanks.

yes NAT boost is enabled. set to the lowest channel which is 36, still the same.

does c9 has the bandwidth limit setting? i might want to take a look over there.
