I recently bought tp link AX1500 and found that it has guest mode. In videos about setting guest mode found in different sources showcase that certain speed can be set in that. But going through the settings of this router, i found no such option. all i could do is set guest networ while either for GHZ with password and no option to set the upload and download speed to be used. Please help if ia m missing any steps or that option is not present in the router itself?
