Im at a total loss.. I dont understand my wireless problem.. I hope someone could help me.. Im using D-link DIR-300 as the router.. the problem is that my wireless seems to be very picky about sending information to certain devices.. my computer and my iphone doesnt seem to be able to surf using the wireless.. however, I can use laptop to surf.. I've done speedtest for both my comp and iphone. averaging to only 20kbps download and 20-30kbps upload.. for my laptop.. eventhough my iphone is just side by side or beside my comp.. it can reach speeds of 1.6mbps download and 300+kbps upload.. even if I go near near using my phone and put next to the router.. the speed is still the same.. very bad.. my laptop different.. go anywhere around my house.. the speed is good.. how can I solve this problem..? your help is greatly appreciated.. this problem on started yesterday night.. it was fine before the wireless suddenly went dead for a while and I have to reboot my router..
