I know that this is a common problem -- the Realtek RTL8187SE card in the MSI Wind is next to impossible to get working correctly. I had issues with all of the following:
  • Slow wireless access point detection
  • Frequent disconnects
  • TONS of dropped packets


In fact, it was so bad, that I found it was dropping more packets than it was receiving.

So, I went ahead and swapped out the card for an Intel 4965AGN. Less than $12.25 US and I have fully functioning wireless with none of the issues.

The procedure involves a bit of tinkering, so I wrote it up on my blog. Hope this helps someone else in the same, frustrating boat.
