@albertHofmann It's supposed to be under "advanced" option when you set up guest network, like mentioned here: How to set up a Guest Network for Deco

@Zigaroo Update via web UI

@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?
