This has happened umpteen times before but whoever said you shouldn't make the same mistake twice is, sadly, mistaken.

Just spent the best part of 4 hours troubleshooting an iffy wireless network connection. In the end it was the network card itself. Now, bits of silicone and silver with no moving parts should not go wrong should they? But they do. The number of cards and DIMM modules I have seen go bad is silly.

Note to myself, to be forgotten next time. If possible. Swap out the card first!

Learn from my mistakes. :-)

Cheers
