Now I'll teach you how to limit and break through the limit:
1, hardware limitation: generally, only hard routes (except soft routes) have this speed-limiting function. This kind of route with speed-limiting function is much more expensive than ordinary routes (of course, some routes can be speed-limited by upgrading firmware), so the landlord will not spend money on expensive routes. Judging from the information you sent, the 2M broadband is almost occupied, so the landlord's route has no speed limit function, so the hardware limits you.
2. Now there are only software restrictions. The most popular software on the Internet is Jusheng Network Management and P2P Terminator. The functions and usage of the two softwares are almost the same, which can limit and disconnect the network speed of any user in the LAN. Generally speaking, only 1 users in the local area network use one of the above two softwares to limit your network speed. If it is serious, it will break your QQ, and its lethality is no less than that of the atomic bomb and missile (halo) seen in the military parade in China.
There are many ways to break through, but the principle is to prevent ARP attacks. For example, you can turn on the ARP firewall function in the real-time protection of 360-degree security guards. When someone uses ARP to limit your network speed, the 360-degree security guard will send out an early warning signal. You can track his IP, and then go to the door directly to find him and tell him not to open this software in the future. If you open this software, my QQ will be disconnected. If he is still using this software to speed limit, you can use LanSee to scan all IP addresses, then find the IP that attacked you and shut down his computer remotely. (Hehe, this method is too cruel)
Have a good time surfing the Internet.
