I live in a rancher-style house in the US (for those not in the US, just a single level home that is usually a bit wider than it is deep). There is an extension on the house that extends past the original brick wall that we spend most of our time in. My office is on the complete opposite side of the house, and that is where the coaxial cable comes in the house to connect to the Verizon FiOS router.
With just using that router, the signal in our extension is mostly unusable due to the brick wall. Because we have some network cable run, I now have an Airport Extreme set up in the extension.
If I turn off wireless on the Verizon router, the airport Extreme will reach the other side, but doesn't work. Same if I disable the airport, you cant get wireless in the extension.
I feel that having both of these running does cause interference though. For example, sometimes devices won't loose their connection to the other base station without disabling and then re-enabling WIFI. Other issues are sometimes slowness or odd coverage in other areas (for example, outside the house, the wireless isn't as good as it was with one).
Both routers are using the same SSID and should be on separate channels. Both are running a 2.4ghz g network, and the airport extreme also is running a 5ghz network too.
What would be the best setup with either
- using the two routers or
- working with WIFI in a brick house?
UPDATE - Adding some notes thanks to Spiff's answer
- NAT/DHCP is handled by the Verizon router, those services are off on the Airport Extreme
- Devices are on separate channels that are spread out
- Both use the same SSID and WPA PSK
- Airport is setup using the default - 2.4 b/g/n, and 5 a/n .
Also, changing the title to better reflect the real question - how do I get this to work the best way? I don't mind not using Verizon's wifi router if I can set up the Airport Extreme to work better - ie not even using the 5ghz band, etc.
