Hi! I've searched long and hard for a solution to this and have found none. I am using a Rosewill RNYX-N250PCe wireless adapter on a Windows 7 sp1 64bit computer. The MB only has a PCIe 16x (occupied by a radeon HD 7750) and a PCIe 16x running at 4x (occupied by the wifi card). I am currently on a public wifi network. Every once in a while when I start playing an online game, the connection drops momentarily, and then reconnects. The wifi restarts when I tab out. This usually repeats every time I try to tab back into the game, causing serious issues. I downloaded Xirrus Wifi inspector and noticed that there are multiple routers, each on a different channel. My computer switches back and forth between two routers whenever this disconnect is taking place.
Additionally, when I play a graphically intense game offline, it drains my internet speed, often times until it disconnects the wifi altogether (as when I'm downloading a file or something).
I have fiddled with all the power options, TX settings, PCIE power management settings, updated drivers, tried with a different wireless PCIe Card, updated firmware on my SSD, motherboard drivers, graphics card drivers, adjusted antennae, made sure there is only one wifi controller software/utility, checked for viruses etc, but no luck.
So my questions (after trying everything else) are, is there a way to prevent the wireless from changing access points within the same network SSID (they have equal signal strengths) and second, what could be causing the drain in power to my wifi card? Is it simply that my psu isn't strong enough? I'm currently running a 500 watt PSU, which is 100 watts more than the recommended 400 for my video card. Or perhaps is it processing priority that is being allocated away from my wifi card or pcie slot? Someone recommended I give my wifi card "higher" priority, but I wasn't sure if that was possible. Any help you could offer would be greatly appreciated. Thanks!
