Try putting the comcast gateway as your main wifi and providing DHCP to it's wifi and all wired connections. Then have the other wifi routers wired to the gateway in bridge mode for the same network as the gateway wifi. You can do the same with the eerowifi. Then it will all be one big happy wifi with lots of access points your devices can connect to. Place all the wifi routers to get the best signal strength in all the places you use wifi.

I have this on my wifi some wifi routers are wired bridges, some are not wired. I don't have a cable modem that has anything but one wire, so I use one of my Apple Airport extremes as my main router to provide DHCP to the wifi and it's wired connections. It is the only thing wired to my cable modem. It also makes a guest network that is shared simultaneously on all the same bridged routers.

Making one big newtwork with lots of bridged access points spread around I get 300mb/s on my devices anywhere on the network in my home. Even had a neighbor that all their devices were on my guest network and were getting 127mbs. They had their own wifi, but my guest was better signal and didn't have passwords so their devices were automatically switching to it.

I only put up the unpassworded guest network because I have a brother that comes to visit that can't seem to keep his laptop on a passworded network and I got tired of resetting the networking on his computer all the time to make it stay working while he visits. Since the neighbors automatically join my guest, I turn it on only when someone is visiting and wants to use it then turn guest off after the guest leaves.
