Deco M5 slowed down after firmware upgrade to
I have two Deco M5 units (one as main unit and the other as satellite) that worked fine until yesterday when the speed dropped significantly from 400 Mbps to 72 Mbps. The firmware was updated to 1.5.1 and it did not resolve the problem. I am frustrated as I have mutliple devices that require high speed internet. Is there way I can go back to the previous version of the firm ware or any other solution?
Also, I tried one solution of making the primary DNS 8.8.8.8 as was suggested in one of the threads that I saw in this forum but that did not help
