MR6110 AT&T FirstNet with external router/wireless access point

[Schielke]

I've had this device for almost 2 weeks and I'm trying to help it work a bit less and more efficient.

I got a cheaper wireless router from BestBuy: LinkSys EA7200

I'm able to disable the DHCP server on the MR6110, and turn-on IP Passthrough. I've attempted manually setting the DNS. I've tried to modify the LTE Subnet Mask to see if I could get a couple of IPs (one for the modem and one for the router hoping this may bridge the gap in their hand shake process) and none of these settings seem to make the external router happy. 

I connect it to the internet port of the Linksys and it is unable to automatically configure. I've attempted bridge mode, and statically setting an IP. 

I've called AT&T asking for any login information that may be needed for PPPoE or LPPT their customer service didn't attempt to elevate the question but referred me to Netgear, who-- after about 1 hour referred me back to AT&T. So I'm here trying to see if someone can see what I've missed if anything. Thank you in advance!

Hi @Efficiencypleez

Kindly check for an available firmware update and let us know how it goes.

Why not leave the MR6110 in router mode and put the linksys in access point mode? 

[Schielke]

I've tried that with the "bridge mode" but then the DHCP does not pass from the MR6610.

Bridge mode means different things for different devices. pretty sure on that one it turns it to a modem only device. 

Thats why I'd try the MR6110 in router mode with the linksys in AP mode.

I understand, I looked at the instructions for the Linksys and Bridged mode acts like an AP, but the DHCP does not pass from the MR6610 to the 4 ports nor does it get "Internet": https://www.linksys.com/us/support-article?articleNum=137888

If you hardwire a pc/laptop into the mr6110, does it work? 

[Schielke]

Yes sir. Perhaps I can try an unmanaged switch later and see if that works.

Did you ever happen to resolve this issue? I'm dealing with the same on my linksys e1000.

My apologies I thought I replied to this! Yes I did resolve it, I switched to an ASUS external router and it worked fine. I'm going back to the LinkSys EA7200 to see if the new firmware fixed the issue! 🙂
