@DexterC Is there a channel restriction on 5Ghz bands in Malaysia? If there is, then you can ask David-TP for customized firmware (don't know if it's available for x20 though)

@Well_Hung_Ling Wait till 2029

@DexterC DexterC wrote I meant channels 149 to 161. Does deco operate on those channels? Yes they do...but it can't be changed manually. If possible, return it & get it from a local store.

@racenerd How did you find out the problem?

Although I very much want this to happen, the chance of it happening is next to zero. There's no liability from tp-link to add WPA3 on pre-2020 devices aka "Wi-Fi 5" devices. The arrival of Wi-Fi 6E...

@Janelle90 You should post this on the Feature Request (Deco) forum
