I have been working with a network professional over the last few days and have been truly stumped when it comes to my internet speed. I am currently a customer of Verizon Fios and have the 1gbps Up/Down package. If I plug anything into my ONT, via cat6, I get over the prescribed amount. When I go through any router device, whether Netgear or TP, I get tanked connection and the best I have seen so far is from my Nighthawk products: RAX50: 450mbps down/156up, RS500: 950Mbps down/2mbps up. I have done almost everything imaginable, along with the network professional I have been communicating with and they cannot understand why the speeds tank so hard once it hits the router. All of the firmware was updated, and even reverted back in the case of the RS500 since the site said the newest version was 1 iteration prior. If anyone out there can shed some light on this I would be eternally grateful. Added context, I am currently hooked up with my TP-Link Archer BE-550 and that speed is: 205mbps down/32up.

Thank you all in advance for any help with this conundrum.
