Latency Issue

I have been having this problem for a while and for the life of me can't figure it out. I don't really consider myself much of a network expert but here goes it.

Lately I have been having a lag spike Issue. I currently have comcast as my ISP.

Anytime that I use more than one computer at a time on my network my latency spikes like crazy. Just doing a normal speed test I was getting about 50mb down and 15mb up.

If say, I stream a video on my 2ndary computer and do a speedtest on my main my speeds will drop to about 11mb down and 11up. I was also doing a ping google.com -t and watching my ping on there. It was averaging about 25-30ms response time however, when I ran a speed test and was watching the response times it would bounce around anywhere from 400-2000 with random request time outs. I can't seem to figure this out and its driving the wife and I nuts. I have tried different routers and still the same problem.
 
Comcast is the problem, are you sure you have not updated drivers for Ethernet by accident say a window update that made things wonky? I would run a through virus scan as well cause it maybe could be something open without you realizing it is open?
 
I am fairly sure but I can double check again. On both computers i used the manufacturers drivers for the nics. I can double check again on the viruses/malware but i ran some scans a few days ago even following the virus removal guides on the forums here as well.
 
That is definitely the issue. You shouldn't have that problem with wired. There are many factors in wireless such as interference from other networks/bluetooth, the amount t of connected devices, signal strength, available bandwidth, and also latency because of those issues. If you have to use wireless, I would first check for any other networks in the area and what channels they are using. Also identify any devices using that frequency like bluetooth / cordless phones, etc. Plug in any stationary devices rather than using wireless. Also, you may want to get a new wireless router that supports both 2.4 and 5ghz at the same time and split the traffic to each. 5th will be better for latency but only to a certain range since it does not go thru objects as well as 2.4ghz

It is wireless currently.

Unless you configure it not to, if you have one device that is G or N and you connect with a B device, your network may drop to B speeds.

Find the B device and upgrade it or throw it away, or change the router config to be G or N only.
