[Discuss] printer issue

[epp at null.net (epp at null.net)]

Comcast will allow a customer to use a personally-owned modem, if this
is what you're referring to. They have a list online of the approved
modems, that I presume were tested to ensure they work.

I have an Asus router that is configured as an access point, which I
have used in the past. As an AP, the devices on the internal network
would pull IP's from the Comcast gateway, but are physically/WiFi
connected to the AP. A negative to this, is that (unlike the Comcast
gateway) the router/AP will not allow the same SSID to be used for both
2.4 and 5.0 GHz WiFI.
