I'd say that your download / upload rates are fine. Now for the fun. Wifi is affected by a number of items, including interference from other routers, interference from home appliances like microwave ovens and 2.4 Ghz cordless phones, age of the wifi mini-card which dictates whether it's running Draft N firmware or approved N firmware, single or dual antenna mini-cards, settings on the router and on the mini-card and probably a few that I haven't thought of. Each one requires a step by step look to determine if you can do anything to fix any problems that you see. As they say in the movies, let the games begin. If you run into problems, we'll need details on the devices to be able to look at the specs, hopefully to determine what if anything you can do.
Only if you need another port for another cable. So, if the tech installed a three way, and it is supplying everything that you need at the moment, leave it as is. Installing a larger splitter and leaving open ports is not good policy as the open ports can result in reflected RF energy travelling back down the cable,causing interference problems. There should never be any open ports in a cable system. They should either be connected to a device or capped with a 75 ohm terminator which simulates the connection to a device.
Over the past few weeks, my internet latency has been jumping from 20ms to 300+ms. Currently it is hovering around an average of 200ms. Yesterday, I called a technician to come and check my cables. He changed my splitters and the problem was resolved for a small period of time. However, few hours later, the latency returned and now I don't know what to do. I am currently using a CGN3ACSMR modem in gateway mode. Also, I am using a laptop connected to the internet via ethernet cable. Are there any solutions to this problem?
Is that seen on a wired or wifi connection, and is that via connection to the modem running in Gateway mode, or from a router connection, with the modem in Bridge mode? Can you log into the modem, navigate to the STATUS.... DOCSIS WAN page, copy the Downstream and Upstream tables and paste them into this thread. Those are the cable signal levels which might still be of interest. And.... are you in a house, apartment, condo, highrise, etc, etc?
It is seen on both wired and wireless. Modem is in gateway mode and I'm in a house.

Your signal levels on both Downstream and Upstream are good. The Signal to Noise ratios aren't so good. Call tech support and have the CSR run a signal check on the modem. Ask him or her to check the neighborhood node as well, which is the next device upstream that the modem communicates with. The signal check should probably indicate bit errors which are at or maybe slight over the acceptable level. Call tech support when you are seeing high ping times so that hopefully the errors can be detected during the signal check. There is either an issue at the node, or an issue that is still affecting your cabling and connectors. Keep calling tech support as many times as you have to in order to document the issue. The more reports on file, the sooner it will grab someone's attention. Please keep us informed of your progress with tech support.
If you're interested at all in the nitty gritty details involved in the Signal to Noise ratio calculation, have a look at the following pdf link, bottom of page 26 to the top of page 29.
Okay, I'll keep you updated on the situation. Thanks for the help.
Currently, the ping issue is resolved and I am having no problems. Thanks for the support.
