We just upgraded to 1 GB router and system and are experiencing very slow internet. When running Verizon speed test it shows fast download and upload speeds but when using third party speed test (Google) it shows very slow upload speed (less than 1 mbps). Our Youtube music videos are always buffering and certain websites like Amazon are hanging.
One other user suggested disabling IPv4 in the ethernet controller settings. How do I do this? I am not the most computer savvy.

If this is only happening on Ethernet devices, go into the the Device Manager on your PCs and disable IPv6 Checksum Offload for TCP and UDP. The steps are:
Other Ethernet devices may also be affected, so look for similar settings if you use Realtek, Qualcomm, Aquantia, etc Ethernet.
If you're seeing problems with wireless devices, especially Smart TVs and Streaming Devices, what you want to disable is IPv6, not IPv4.
To do this, log into your Verizon Router at https://myfiosgateway.com/ using the Credentials found on the side of the router. Once in, go to Advanced --> IPv6. Set IPv6 to Disabled and click Apply.
