RBR 850 Slow WAN Port

[Webster_Rock]

The house was recently struck by lightning.  Before strike I was getting full spedd( 993 MBs) from the ATT fiber.  After strike the WAN port on the RBR850 reports as 100MB.  I hooked a laptop up to the ATT port and got full fiber speed, so the ATT box is good. 

On firmware 4.6.3.9.  I've done several factory resets and still slow.  I've changed calbles and again no luck.  Could the lightning have somehow permanently "dumbed down" the 1,000MB port to 100MB?

Did you pull the power cable from the RBR and ISP Modem for 1 minute then back ON with the modem first then RBR? 

Swap LAN cables between the modem and RBR. CAT6 is recommended.

Left them unpluged for 5 minutes.  Yes I switched CAT6 cables.

Time to order another one.
