Hi

Thanks for quick reply.

No, don't have yet - I plan to buy U.S. version.

       I had before RE650 (fast and powerfull) but lack of bands U-NII-2A (channels 52-64), U-NII-2C (channels 100-144) made him uselless - has been returned to seller. My router (Wi-Fi6 ax) has bands U-NII-1 (channels 36-48), U-NII-2A (channels 52-64), U-NII-2C (channels 100-144), U-NII-3 (channels 149-165) but the the best (faster transfers) give band 160MHz only. My router (Wi-Fi6 ax) works on160MHz on following channels: 36,40,44,48,52,56,60,64,100,104,108,112,116,120,124,128 but channels 36-48 are used by neighbors so channels left for me: 52,56,60,64,100,104,108,112,116,120,124,128 but setting the router to rest of free channels (52-64, 100-128) is impossible due to lack of this channels in extender (RE650). If the RE650 had bands U-NII-2A (channels 52-64), U-NII-2C (channels 100-144) the matter of selecting the channels would be simple and the device would stay with me.

That's why I'm asked - I want to avoid buying wrong extender again.

       Tp-Link claims that RE605X has Wi-Fi6 this mean that should be support 160MHz.  www.tp-link.com/en/wifi6/  "What is Wi-Fi6? (as known as AX wifi)  Wi-Fi6 uses both 1024-QAM to provide a signal packed with more data (giving you more efficiency) and a 160MHZ channel to provide a wider channel to make your Wi-Fi faster. Wi-Fi6 expands the WiFi band from 80MHz to 160MHz, doubling the channel width and creating a faster connection from your router to the device".

You answer contradicts general information about Wi-Fi6 standard. Hmmm... Are you sure did not work with 160MHz?

Hi, thanks for your patience.

 I guess you have EU version?

And may I know why did you need this details?

I have some of details:

1. 2.4ghz channel: channel 1~13;
2. 5ghc channel: band 1+2+3, not  supported band 4: channel 36-48, 52-64,100-140；--so It is U-NII-1/2A/2B/2C
3. Did not work with 160MHZ;

Thank you very much.
