Troubleshooting Your Network Connection: Power Off!
A few months ago the network connection on my desktop computer stopped working. I tried what I considered to be the obvious troubleshooting methods: a different network cable, connecting the network cable to my laptop to see if it worked, forwarding the wireless Internet from my laptop to my desktop… all of which pointed to one unavoidable conclusion: the network port in my desktop had to be busted. As a last resort, completely expecting it to do nothing, I turned it off for about ten minutes. Subsequently, everything was working the way it should.
Of course I’m familiar with the 30-30-30 rule for routers, but I didn’t realize some variety of the process might be helpful on desktops as well. Just to clarify, I hadn’t changed anything about my networking setup as it had been for years. I can only imagine some kind of static charge snuck in somehow.
