I have an HP Touchsmart 520 1130 PC with Windows 7 and Ralink Wireless adaptor. Often the adaptor (and so wireless connection ) stops working , usually after being on standby , ie. there's a red cross on the wireless icon in bottom right of screen. The adaptor is not visible in device manager either.
It would usually be ok again after a reboot , but now even rebooting doesn't always work. Sometimes I have to reboot 6 or 7 times before it works. I tried updating the driver , but it made no difference.
any ideas ?
