And that's the funny thing. Autonegotiation *is* the standard! ;-) It's when you don't use auto that you've strayed from the standard. However, I still find about <5% of the time I run into situations where I just cannot get auto to work right. Most of those I suspect bad cabling but it would have been too difficult to fix at the time. Here's a tip that I've found helpful, even if things seem to be running fairly well after you upgrade to a newer switch. From time to time, clear the counters and wait a while, then check for alignment errors, late collisions, and CRC errors. Any of those are a good sign that you might have a speed and/or duplex mismatch. I've been using this technique to slowly fix the connections to some of our servers. Quite often the servers will appear to be working just fine but they still need to be fixed. Other times, our LAN group spends weeks of intermittent troubleshooting trying to solve a problem and it never occurs to them that it might be a speed/duplex issue. They're always looking for application or OS problems and they sometimes don't think to ask me about it until they've run out of ideas.
