My internet runs 150down and about 30up. I'm using netgear n450 docs is 3.0 as my router. I'm using my internet mostly wireless, about 9 device(phone, iPad, laptop and tv) only 2 is connected through wire by which runs fast as usual. I wonder what set up should i do on my router for a better wireless connection. Should I split my coax cable internet and connect another router or is there any settings that I can change to maximize my wireless internet speed. Any advice?
