yes, that is correct. it is always kilobits per second that is advertised
marami akong mga nakikitang nagrereklamo lagi dahil daw yung smart wifi (smart bro na ngayon) nila ang bagal daw ng speed. thats because they dont know that they are subscribed to 128kilobits per second max not 128kilobytes per second max. so max download speed mo is only 16 kilobytes per second. max yan ha, not average. so mabagal talaga sya
for upload speed, since most commercial DSL is ADSL, in your case max upload speed is only 64kilobits per second so thats only 8kilobytes per second max upload
