Limit IP address ranges with BGW210-700
I recently switched from Xfinity to ATT fiber with the BGW210-700 modem/router and am enjoying wicked fast speeds. I have two issues, that I THINK are tied to how the router assigs IP address ranges. When I had Xfinity, I had none of these issues with the same set up (except the modem/router)
Issue 1: When trying to set up my Sonos system on the new router SSID, I cannot get it to install. The support person at Sonos tole me it is because the Sonos controller on my iphone is not registering in the same IP address range as the Sosos devices. Every time I start over, it behaves differently, so this answer makes sense. So, what do I need to change on the modem/router so it issue IP address is the same range?
Issue 2: I am sure this issue is related to to the first. In my home, the location of the modem/router is not ideal (basement), but it is right next to the source of ethernet wiring to every room in the house. This provides me great flexibility, but also a few challenges. To provide wifi coverage in the extremes of the house, I have ethernet lines going from the router/modem to Apple Airport extremes. When I set up the Airports, I gave them different SSID names since devices could not discern whether to connect to the router/modem or the Airport. This is less than elegant as my ipphone (or any other device) has to switch SSIDs as we move around the house. Furthermore, even with a different SSID name for the Airport, when I set up some devices (in this case, my DishNetwork DVR), I get a warning that the SSID is showing up multiple times, do I still want to connect. This screams of the SSID being tied to mulitple IP addresses.
So, in summary, 1) How do I configure the router/modem to only issue IPs in one range. 2) How should I set up my Airports so they use the same SSID/IP addresses?
(BTW, for the Airports, I know about the two options of either extending or establishing a new network. I have them set to 'establish new' since they would never get a strong enough wifi signal from the modem/router to rebroadcast it. Again, when I had Xfinity, I had it set this way with using the same SSID name as the router./modem and had no issues.
