hi i have a imac and i used to get around 500/800 kb per second.. after awhile i wanted internet for my wii so i got a linksys router... everything was fine.. was set on usb connection to my computer but after my power went out it came back on and my router is now set on wireless, (but i never re-turned on airport so i dont understand how im getting internet through a wireless modem with airport off, well my usb cable is stil connected but my router is set on wireless anyway) and now i get less then 200 kb per second and i dont get that.. so i got speed download and now my speed is 200/300 kb persecond which is still slow.. so is there anyway to get my kb/per second up again? must i do something with my mac or with my router or... anything ( and my router is a mystery with me because when my router was set on usb cable somehow my wii was gtting the wireless signal) please help!
