ONT negotiating only 100Mbps with router

Has this happened to anyone else using GigaBlast? Every now and then, I notice my network is slow and when I check the router, my Alcatel-Lucent ONT has switched to only a 100Mbps connection to the router (RT-AC68U). Most times I can reboot the router and it will come back at 1000Mbps. Twice now, no matter what I do, (reboot, reboot the ONT, swap routers), it will only negotiate 100Mbps. The last time this happened one of the techs at Cox tried sending a reset to the ONT and bricked it. My Internet was down for 2 days until they rolled a truck with a replacement. Ugh! It's happened again today and I can't get a 1000Mbps link. I placed a service call for a replacement ONT. Seems like these ONTs just freak out sometimes and won't negotiate 1000Mbps. Just curious if anyone else is having this issue. Thanks, Dave

    I'm not aware of any known issues to this effect. In addition to trying different devices I'd suggest swapping cables and making sure you're using a CAT6 cable for best results.
