PA-450 and ATT BGW320-505

Question, I setup my PA-450 and ATT BGW320; however, I feel there is a loop as the connection sometimes drops or has slow connections on live connections like streaming TV and or live video. I guess my questions are as followed below.

First, my setup is fiber going to the BGW320 that I could not get to change it to copper via ONT device as it will not work and not supported (I tired this anyways and it seems not to work)

(BGW320)<-->(PA-450 WAN Port)

(BGW320)<-->(SWITCH)<-->(PA-450 LAN Port) I tried with VLANs but ATM removed them to get it to work and pull PUBLIC IP from BG320.

(SWITCH-->BGW320)

So, is this the best way to set it up without buying an extra wireliess router? As is, DHCP is ran via the PA-450 and still using the BG320 for wireless clients. All clients is the PA-40 for DHCP.

PA-450 setup in L3 mode and all functions seem to work outside the seemingly loop?

Does anyone have this working, if so how did you wire the devices and anything I should be looking out for?

Thanks for any help...

not entirely sure which options are available on the BGW320 in regards to traffic segregation (between internet link and wifi network) but i have a similar setup and have decided to keep things simple and use my ISP router simply as a "modem" and assign the public IP to the external interface of my firewall. i put my wifi AP behind the firewall and disabled wifi on my ISP router

@MiamiDolphins,

I would seemingly echo what @reaper mentioned. I would not recommend trying to maintain the wireless functionality on your ISP gateway and simply pick up a dedicated access point and place it behind your PA-450. Not only does this ensure that your wireless clients pass traffic through your PA-450, but it will more closely resemble an actual production network.
