Today, I found a small problem, but it was so important. I didn't expect to meet many times before.
If a computer dual network card, if the inside network is kept connected, the external network (online) is disconnected, and it will not be net! I have never known it before, I thought it was the problem of someone else's landlord. ,Ha ha.
Simply break the intranet, first connect the external network, then connect it online. The Internet is only connected according to the first available connection.
