This forum has always helped me with all of my mac problems. If you guys can help me figure this problem out, I would SINCERELY appreciate it. I'm all out of options here. I've got my mom's Gateway Quad-Core desktop PC (running Windows 7) hooked up at my house for the time being. I have an Airport Extreme as my router, and also an Airport Express used as a network extender. I hooked up the Airport Express this morning, and that's all configured correctly and working properly (so it's not an out-of-range issue). The Gateway Desktop has a full 5-bar connection, and is running a USB D-Link DWA-140 wireless network adapter. The problem is that it cuts the connection literally about every 30 seconds. Here's what I've done so far: 1) Installed the updated D-link drivers. Didn't work. 2) Installed the NEWER, updated Ralink drivers (parent company for D-link...the DWA-140 adapter has the RT-2870 inside, so I used the appropriate driver, which I thought surely would fix it...that's what everyone told me to do thus far). Didn't work. 3) Checked my USB Power Settings in control panel and set them to never put the ports to sleep. Rebooted. Didn't work. 4) Right-clicked the adapter under "devices" and checked the power management settings. Set them to "maximum performance" (that's all I could do). I'm out of options. Any ideas? Any links to better drivers? ANYTHING? Thanks so much. I know it's a stretch that it's an Apple-related issue, but none of the PC guys could help me, and I figured maybe it's related to an airport setting? Thanks for reading, and thanks even more in advance for any advice.
