Hi All
Looking for assistance on setting up a WRP400 VOIP Router behind another router (WRT54G).
The WRT54G is acting as the primary connection to the internet. Its Internet port is connected to the feed from my ISP, and provides DHCP and NAT for the rest of the house. It also provides Wireless access for the upper floor
I have a single CAT5 cable available to connect to downstairs, where my WRP400 is to be installed, and where the primary telephone jack is located for connection to the VOIP router. This is to provide the same SSID as upstairs but on a different channel so that laptops will auto switch as one moves around the house
This all worked fine when I had a WRTP54G as my VOIP router downstairs. The single feed from the attic went to one of the LAN ports on the WRTP54G enabling single segment throughout the house (no point in auto switching access points if re IPing is required). It did require that the Internet port on the WRTP54G was connected back to one of its own LAN ports to function ( I assumed that was because VOIP traffic would only traverse the Internet port, and would not function if this port was down). However, all worked perfectly, and everything was on the 192.168.15.x subnet.
Here is what things looked like, and hopefully still can look like

Then my WRTP54G died, and the next best thing I could get was a WRP400.
This unit goes nuts if I try to configure it the same way. Once the Internet port is connected to itself, it basically freezes up, and wont work until a total reset is done via reset button.
Because of the locations of my telephone jack, and the presence of only a single cable between upper and lower floors, I cant place the WRP400 upstairs as the primary router, as my telephone would then have to be in the attic. Nor can I bypass the attic and run the ISP feed to downstairs, as then I would be unable to connect the WRP54G upstairs as a secondary access point. In that second scenario, I've consider installing hubs at either end of the single cable between floors to allow both the ISP segment and the internal segment to be available on both floors, but then I just end up having four powered boxes instead of the two I had working happily for 2 years before this.
I wish the WRP400 were as forgiving as the WRTP54G!!!!
Does anyone here know how to cascade the WRP400 behing another Linksys router, keeping it on the same segment as the primary router, yet get VOIP to work? I found cascaded articles, but they all assume you are in a position to place the VOIP router as the gateway to the ISP.
Any help would be greatly appreciated!
Best regards
Ken
