So I am going to type up my full story to kind of give you guys all the info that you may need to help me solve this...
We recently upgraded our internet package to a 45mb download speed package with 5mbs upload speed. The ISP (CenturyLink) sent us a new Modem/Router (C1000A) to be used with our new package. We plugged it in and set it all up and we were good to go. The computer that is directly connected to the C1000A was getting the full speed of the package and the Wireless devices were getting around 11mbs download speeds. I wanted faster speeds on the devices that were connected wirelessly so I went to Best Buy and picked up an EA6200 Router.
Got home and followed all the instructions that were provided in the box. Turned off the WiFi Signal that came from the C1000A to ensure that the only signal going out now was from the new EA6200. Went and ran a speed test on a PC that is connected wirelessly and it got around 35mbs download speed and 4.5mbs upload speed. I was so happy about the new speeds!
I then noticed that as I was playing some PC games online such as League of Legends and others, there would be MASSIVE lag spikes that froze up the game and then resumed back to normal after a few seconds. This never happened when I was on the internet through the old wifi signal from the C1000A Modem/Router. At first I was a little upset, but I still continued on without asking anyone in the Linksys Support for help. Until just 2 days ago everything was alright...
Now when I run a speed test on the PC that I tested before, I am getting 1-2mbs download speed and 4.5mbs upload speed. I can no longer play any online games or even watch a Youtube video at 240p quality without it freezing up only 3 seconds into the video! So pretty much the only way that I can use the internet is to use the computer that is directly connected by Ethernet Cable.
I spent a couple of hours today looking through some forums and even doing a Live Chat with Linksys to see if they could help me with my problem and I have yet been able to get it fixed. Now I will list some of the things that I have tried along with some of the settings that I have on in my router.
