MacBook Pro wireless Internet access is slow

My background is as follows:

1. my family is safe with 2 M iron broadband. If three people access the Internet at the same time, they will be stuck, but they can support two people's first videos. In fact, they have connected to N terminals, iPad, iPhone, and touch.

2. when I just got a good tie Tong, my MacBook Pro was the best to grab the Internet at a speed, because of its good performance, I bought a 15-inch high-end configuration in January (with a company configuration, it's not my... 555555)

3. Later, I found that my notebook was very slow in the morning and could go to QQ, but it was very slow to open the web page. Many of them could not be opened.

4. I set the wireless route value, bound the MAC address, and controlled the bandwidth. However, I was angry when I was unable to open the webpage when I was alone.

5. I suspect it is a routing problem and a problem with the wireless network adapter, but I am working in the company at a normal speed, wondering...

6. one factor that has plagued me all the time is that I have installed a Windows virtual machine, and then my network speed seems to be faulty, but I am not very familiar with the principle of computer learning software, this clue has never followed.

7. I used thunder to download things at a speed of 200kb/s.

8. In an instant, I know why. I must have installed the Virtual Machine and interfered with my DNS resolution configuration. Even if I uninstalled it, I saved the changes.

Solution:

Check the DNS address of the network cable provider you have installed (my network cable is tietong, so I have added 211.94.4.1 or 210.52.207.2 ).

Then, manually add a DNS resolution IP address in the advanced network settings,

And so on. If someone else encounters and solves the problem, I hope to discuss it and break through the difficulties !!, I have been sleepy for two months, Grandma. It's so nice to get online now !!!
