I am going to a website that tells me your network latency is high 150ms I use firefox 30 Have internet connect speed of 18.2 meg what does this mean and where or how would you change or fix this?

Latency is affected by many things. Best method for testing latency is to ping while no downloading or streaming etc is happening to a destination of choice. Not all sites or servers will return a ping request as part of an anti DDos attack configuration.
I test my latency online by simply pinging www.google.com such as
Ping www.google.com
in which i get

Getting latency off of a website out there that tests latency I dont feel is the best method. There may be many hops between you and that website. If you run a trace route you can see all the hops in between and where the most latency is occurring.

If you have a local issue with latency you can find that by pinging your local router such as mine is at 192.168.150.1 in which I perform the following

Your local latency should be very very little just like I have. If you have wifi with weak signal or neighbors on the same channel of wifi you can end up with radio competition and router and computer work to pick what packets are your traffic from the noise and will add latency. If this is the problem reconfigure the radio of the router or access point to a channel not used by neighbors or other wireless devices and try that. If you have a weak wifi signal you also will get high latency as for packets have to be retransmitted that failed to transmit etc and this adds delays in communication.
Hope this helps
