Hi hope can get help here. Just signed on StarHub fibre 100 mbps. Provided ONT and Dlink DVG-N5402SP. Did not think through during installation and the router is now downstairs while 2 PCs and laptop are used mostly upstairs. LAN connection getting 94 mbps but once wifi with laptop next to router dropped to 22 mbps. Upstairs dropped to only 6 mbps. Bot a Aztech repeater thinking it would help. It boosted the wifi signal from fair to excellent but speed even worst without repeater as it dropped to 3/4 mbps. Called Dlink and changed some settings boosted to 28 mbps next to router. Still low upstairs. Called Aztech. Just asked me to upgrade firmware. Did not even boost speed at all. Driving me nuts as my son's pc which used to get 70 mbps on cable (modem was fixed upstairs) n now it cant even get pass 10. Can any one help me? Do not hope to run cables all over the house to get improved signals. Oh, thought of homeplugs but due to differerent phases, cannot be done. Tks in advance.
