Question on splitters/ping plotter

1) is there any benefit of using a 5-2000 mhz splitter over a 5-1000 mhz splitter?  I'm running gigabit internet

2) when running ping plotter, 2 things i notice 

• There is severe packet loss at hop 1 (my router) 
• There is higher ping ranging into 150-200 ms at a certain hop that is in many of the routes when pinging different ips.

Example: I pinged cox dns and I pinged Google dns.

Both of these (and many other ips) have hops 

100 .122.141.112

and
100. 122.141.114

and each of these are the only hops on the router creating high ping.

Either of these ping plotter instances an issue?

And does the splitter make a difference?
