Wifi signal is not as good as it appears, help adjust sett-

Hello BBs,
Thanks for your time in advance again! I have Time Warner 20meg down and 2 megs up. My family has trouble with apple TV and iPad connections in the living room and it’s obviously the wifi. I need help to tweak and adjust my wifi settings. I have a separate wireless but remove it because I assumed this was just as good at this point. Please advise!
Thank you,

Get a better router.

Or get a repeater (a router setup as a repeater, just make sure you can install dd-wrt on it).
Answer #3
Try going into your router configuration and change what I have highlighted in the image below to a higher channel such as 11 – 2.462GHz:

Here are some other tips you can do to help make the signal strength better:

Answer #4
I have to check out the repeater!
I will increase the wireless channel but I am looking to do it on 5g…will that matter?

What is 5g? You mean 802.11g?
Only matters if your NIC has restrictions, like N only.
Answer #6
I think he means 5Ghz, just a warning though, 5GHz isn’t supported by all devices so keep that in mind.
Answer #7
Yes, I just noticed that, I guess what I will do is have the original modem/router just do G, then I will have a secondary for 5ghz and see if that makes a difference. Btw, have a Motorola as a modem/wireless. Thanks for all your inputs!!!
Answer #8
Use inSSIDer 2.0 on one of your wireless devices and see what channels other people nearby are using, then avoid them. Most people use channel 1,6 or11 as they are common defaults on routers.

You will find that the 5GHz range will be unused more than likely, however as stated above, not all wi-fi cards/devices support dual band.
You’d be much better changing to wireless N 300Mbps dual band, but that will involve changing your router and probably all of your wi-fi cards. Wireless G also comes in 2 different strengths, 54Mbps and 108Mbps.
