wan to ask opinion... have read the last few pages n quite a lot of discussion on the router... currently still using tm oren color router came together with vip5... currently have upgraded to unifi30, but noted the speed is sometime worst than vip... direct download speed from the same site will fluctuating between 100kbps to 1mbps but last time on vip5 was 1.7mbps... is this due to limitation from the router?
