I need bandwidth control in C6 V3.20 router. this particular feature was my choice of buying this router. now i came to know that it dont have that. return window has already closed by amazon. i searched for this feature in forum, i found a thread. This thread was posted 1 yr ago saying that feature will be rolled out in OTA update, still no such feature introduced, A priority on off switch is in there, which literally sucks. Can't there be any walkaround for this feature?? Now what do I do? not any use of guest wifi also, only to seperate wifi, no control over usage(except parental control, we can't add every guest network in parental control manually) . plzz roll out this feature via OTA and at least tell ETA its 1 yr since that thread said that.
