Questions about connecting my ISP's Pace Gateway 5268AC to Netgear GS748t switch

I posted this topic under modems, but still unable to connect my switch to the ISP's modem/router.

 

AT&T supplied me with a new PACE 5268AC modem/router. It has 4 ethernet ports on the back which I plugged my two switches into. One is a Linksys SR2024 and it connects fine. The port LED's light up and that switch functions. 

 

When I connect my GS748t to the second Pace ethernet port - nothing happens. No led's light up and the switch is not recognized at all. The switch is on and waiting. When I connect the netgear switch into the Linksys switch - it works. The switch gets it IP address from the PACE's DHCP server and the devices connecte to the Netgear connect. 

 

Is there a configuration on the GS748t that I can set that would cause it to be recognized? I have no understanding of what could be happening and if there is a solution. I'd like to separate the linksys from the netgear so I can have two separate segments (isolate multicast traffic - IGMP doesn't work for me).

 

My previous AT&T router/modem discovered the GS748T just fine. So there is something different about the PACE router/modem. I searched the Pace's documentation and Netgear and can't find a way to make this work. So any help is appreciated.

i found the answer for anyone else with this issue ...

 

I posted this problem on the AT&T forum as well.

Someone replied to switch off auto-detect on the port the netgear switch is connected and to set to maximum speed (i.e. 100baseT).

Also - to change the port on the Netgear switch that the Pace connects from auto to the same fixed speed as the PACE router.

 

Once I did that, the LED's lit up on both ports and my switch connected. All is working now - and most important, I have been able to isolate the UVERSE multicast IPTV packets. My wireless devices are working again at the same time as TV's!

 

It was a simple fix.
