My Microsoft Wireless Networking Wireless USB adapter, which I've had for several years, sometimes doesn't work when I start my computer up (it can't see any wireless networks). Usually I fix this by either right-clicking and repair, and/or disconnecting and reconnecting the adapter. However sometimes it takes many attempts and it's very annoying. I'm using Windows XP. Are there any fixes for this, or do I just need to get a new USB adapter?
