Router and Access Point

So I have the newst Comcast modem (TG3482G) which is a modem/router combo and I have a Nighthawk R9000. I want the Comcast modem/router combo to send a WiFi signal to the downstairs, and I want the Nighthawk set in access point mode to send a WiFi signal upstairs, for the Comcast one is not strong enough to cover both neither is the R9000.

 

Now when you set up the Nighthawk in access point mode you type in you SSID and password from the one given by comcast and it then suggest that you disable the WiFi on the comcast router so it doesn't interfear with the Nighthawks access point.

 

My question is why do I have to turn off my Comcast's WiFi, other then "it will just interfear"? When you set the Nighthawk into access point mode it disables the routers functions, so what is the interfearance? Why cant I have both enabled? I need both inorder to cover my whole house (range extendes don't do the job).

 

I expercenced the consiqueses by having both WiFi's enabled and something happens behind the sence causes the WiFi to jam and not work in total. I assume both decives tried to hand out the same IP or somthing and just caused a jam?

 

Shouldn't you be able to have Comcast be the main router that send out a WiFi signal, and have an access point connected via ethernet to "extend" the signal in a different area, so its almost like one big mesh network that people can go from room to room and roam with easy? If so how? In addition I have a second R9000 which I would like to use in my basement in access point mode, how can I add this to the mix without jamming eveything up?

    If I change the channel could I keep the same SSID and password?

     

     


    You could try that. If it works, great. Problem solved.

     

    However, whatever you do as they move around wifi clients have to "forget" one connection and then move on to another one.

     

    Most of my wifi clients happily handover between sources without me noticing. (I have two separate networks in the house and in my separate office.) I use different SSIDs so that I know which one I am connected to. I use the same password because it is easier to remember.

     

    In effect, it all comes down to the abilities of the wifi clients. You make it harder for them if you have two different sources on the same wavelength and with the same SSID.

    Just configure the R9000 as a (Ethernet LAN connected) wired Wirelss Access point with the very same Wi-Fi config you have on your primary ISP router.

      I did that as stated in the 2nd paragraph, it was setup in access point mode with the same SSID and passwords as the promary ISP router. And with both having WiFi enabled it caused the jam, I had to turn off the primary ISP's router's WiFi off as Netgear suggested. But I need both on without it jamming the WiFi.

        What does that mean?

         

        If you have two wifi sources with the same login credentials on the same wifi bands, then you must expect interference. It is how radio works.

         

        Try different wifi bands and/or different SSIDs. You cab  use the same password.

         

        Decent wifi clients will automatically switch between the SSIDs as stuff moves around the place.
