Extremely slow upload speeds w/new Flint 2

I just bought a Flint 2 and installed the latest Snapshot for this router. Its working fine and seems to be okay. The issue is with the upload speeds. I have Verizon Fios 1gig plan and on the ISP router and even the ASUS router's Ive had, I would always get around 900/900 on wired Ethernet. On this router, Im getting 900/250 on wired Ethernet...

I have an Intel Killer NIC and I read about disabling ipv6 on the PC which I did, and that didnt work either. I did it via the Powershell from Intel's own website suggestion and then verified via Device Manager, right clicking on the adapter etc.

I would conclude that there might be a setting on the router that Im missing? I cant fathom that its an issue on the PC itself, as Ive done what I can do based off what Ive researched...

thanks!
