Problem with high latency/ping
Hello all. We received our 5g Gateway two days ago and so far, have big problems. We've been testing our latency and speeds over and over at https://www.speedtest.net and have observed the latency/p...
Finding the max value is pretty straightforward. Here is a link to a netgear article about using the ping command from a Windoze DOS prompt:

How you would put that in effect can vary though. Some routers have a way to set it on the router itself so your auto config clients pick it up right away. Otherwise you can manually set it per machine from an Administrative cmd prompt (search for cmd and right click to launch as Administrator):

Would note this is somethimg that can trip up some VPN's. Some may default to assuming they have the headroom typically available to insert their headers (somewhere around 1450-1460), but TMO is eating up additional space with their header information. If that VPN cannot have it's MSS or MTU adjusted to something below 1400 (like 1380... 1420 MTU - 40 for the VPN), it can cause a lot of problems.
