Not sure when this problem started, but my download speed is very slow on my laptop. Other laptops and devices in the room get about 20-30 Mb/s download and up. My computer gets about 1-5 download and 20-30 upload. I reinstalled the default wireless network adapter (Qualcomm atheros ar956x) and the speeds were back to normal for me. But after restarting the computer, or putting it to sleep and then waking, the slow speeds return. The speed is normal in safe mode. It seems like something is conflicting with the driver, but I do not know what. The laptop is a Lenovo G505s.
