My ISP is AT&T. They hooked up my entire house with relatively decent internet, with only a few devices using the system at a time. I was wondering, since I have a large house, if there's anything I can do to boost my internet performance on "internet dependent" games such as Counter Strike? Attached are some images from two different speed test websites, www.pingtest.net and www.speedtest.net respectively. There's a stark contrast in the ping and DL/UL speeds coming from both. Remember, I'm upstairs in a large home and here's my question. I didn't want to route a hardwired connection around my house and through the wall to my room in order to reach the modem/router that's downstairs in the laundry room (the one provided by AT&T that has a 2.4/5ghz option). Upstairs, I have a Linksys Cisco Wireless-N router, Model Number WAP610N and a Netgear Powerline AV200 Adapter XAV2001 hooked up into it, both plugged into the wall. Additionally, across the room, I have a Netgear 85Mbps Wall-Plugged Ethernet Adapter that is obviously plugged into the wall running directly to my PC. My question is, if I'm getting a mix of pings and DL/UL speeds, (57ms on pingtest.net and 28ms on speedtest.net), why am I getting an average of ~80ms on CSGO/other online games, with times of it spiking into the 250's and in some cases, going well above the 700's? And yes, I've reached 999 once. I'm wondering if there is anything I could pick up at a local hardware/networking store or maybe BestBuy or anything I can buy online that could maybe help deliver that sweet, sweet ping I get downstairs when I run speed tests right next to the actual device in my laundry room? Sorry if I sound like I don't know anything about this, because I don't. Heck, I don't even know if I'm in the right forum, but maybe one of you guys could help point me in the right direction.
Thank you for any and all advice!
