So I am a bit puzzled. I need to fill out a dead wifi spot in my house. Well, it isn't dead so much as connection strength for most devices is around 15-20%. I see that I can buy a wireless extender that claims to boost wifi signal. Sounds good but what is the point? I can connect to that wifi extender and have near 100% signal but wont the speed between the extender and the wifi router be poor so my bandwidth would still be very limited??????
