OK. This is a tough one.

Right now, I have about 12 devices hooked up to a Verizon MI424WR rev. I FIOS Router. I'm not in the sticks and generally get very good up/down. Just now on Ookla I got ping of 12ms, download of 64.38 mb and upload of 53.63. And generally see numbers like that all the time. The devices range from a couple of older dell laptops, an apple tv, 4-6 iphones (depending on the day), 2-4 ipads (depending on the day) and one MS surface laptop running mostly multiuser video chats and some pretty serious graphic rendering programs. So, router is certainly well used.

Today, I attempted to connect to new Dell laptops (actually two duplicate refurbed Insprion 3593s running Windows 10). They get NO access via the router. Barely anything up down on Ookla and other test sites and often the test sites will not even load (much less even the Google home page). Cannot download drivers to update the Insprion 3593s via the FIOS router.

When I connect them to the Verizon MI424WR via ethernet, they get blazing speeds. Same when connecting via a colleagues AT&T mifi and another colleague's iphone using the hotspot. Indeed, I could use the colleague's iphone to download a few driver updates.

Why on earth would the laptops get such poor speeds from the FIOS MI424WR and get great speeds on "other" access points? Any help and tips appreciated! Could it be as simple as the FIOS MI424WR limits the number of devices? I'll point out that the FIOS MI424WR delivered GREAT speed to all of the devices above WHILE the two Dell Insprion 3593s were trying to connect.

Any tips appreciated!

Thanks!
