Staying in a hotel with friends, there is only one network cable, so I bought a router to build a wireless network, which is very slow.

The hotel's network is shared by all guests, so when others are using a lot of network traffic, your network speed will slow down, and QQ whirlwind has a strong ability to grab bandwidth and can grab more speed.

If you want more bandwidth, you can use the software "P2P Terminator", which can detect all users in the local area network and limit the speed of other users to improve your speed. I often use it. Hehe, it's quite convenient. If you don't understand anything, you can keep asking me.

PS: When you use it, you should also leave an online live Q for others. For example, set a limit for them to upload 10k and download 50k, otherwise they will be afraid of larger foe-
