To start off: OS: Windows 8.1 This is a wireless connection (My computer is about 10-12 feet directly above my router) My ISP is Time Warner Cable (Road Runner Cable with Power Boost) Modem/Router combo Arris DG860A No firewall software installed other than the standard Windows Defender. I have installed the latest drivers per Netgear instructions (Windows 8.1 driver). All drivers and updates have been done to windows. My Problems: I have recently built a computer and am using a Netgear WNA3100 Wireless adapter with it. I don't have a problem connecting to my network but I do have problems with connection speed. When I start my computer or unplug/plug in my network adapter I show 300Mbps, which then QUICKLY degrades to about 5.5Mbps. Sporadically, it will go to about 115Mbps which makes the internet usable but most of the time it is at a crawl. My Speedtest and Pingtest results very greatly from back to back runs. Ideal: Typical: Pingtest is making me a liar and not that bad. 1st pic is recent. 2nd pic is normally what it looks like. I'm at a loss. There are times when the network is at 300Mbps and everything flies. And then it poops out in no time flat and I can't do anything. Also, during those times when the internet is actually working really well I've been trying to download Assassin's Creed:Black Flag. I can actually download it at around 2.4 MBps which I'm super happy with, but EVERYTHING else on my network can't do a thing with the internet. Im talking 0.04MBps download speed on my phone when trying to download black flag. What could be causing this? Seems silly to route all my bandwidth to one thing.
