Would unplugging/plugging the lan cable from the mb while the power is on cause any problems?

I just assumed it was ok but I had connection issues right after I did that yesterday. The usual restarts and cold boots didn't solve things. And it was only after I connected the lan port to another modem which showed that mb lan port was still operational and replugging the original lan cable (while the power was off) fixed the issue. I'm not sure whether the lan port was somehow misaligned with the cable socket or something else.

I do it sometimes by accident and it was never a problem. Sounds like your router just got confused though. It was probably not detecting the new connection after the disconnection.

There shouldn't be any issue with unplugging a network cable, I must unplug 100s a day without issue

That was very unlucky of you. Static is a silent, deadly bitch. I've seen it kill a computer with a USB drive even!

NICs or built-in Lan ports are made specifically with on-the-fly connect/disconnect in mind. Somebody said his switch or router got confused. That's all that happened.

But there's also the story about static electricity. That s*** happens, too.

Back in the day, I was overboard on technology because I was making money from it. I needed a household LAN, and I had a choice of two NICs by Intel. The simple NIC was priced at $140. The other one I also bought was made for a server. I was fiddling with it, on a very dry day, scooting around my carpet in jeans on my knees. "Zap!" When it went south, it was like watching $300 flush down the toilet.

And those were 1993 nominal dollars . . .

I thought that was the case and power cycled the router but that didn't help right away. It was an odd thing and I think that there might be a problem with the lan port socket.
