Why is the transmission speed in the home wifi LAN so slow

In the LAN established by wifi, the maximum transmission speed depends on what protocol the router and the network card follow, which is determined by the router and the network card, and the transmission speed is determined by the device with the lowest rate.

The common network protocols are:

It is a standard for wireless local area networks. Its carrier frequency is 11 mbit, which is the most famous of all wireless LAN standards, and it is also the most widely used. A total of 14 channels with a bandwidth of 22MHz are available in the frequency band.

The successor standard is that its transmission speed is 54mbit s. The frequency of its carrier is the same), the original transmission speed is 54 mbit s, and the net transmission speed is about . compatible with the device.

In January 2004, the IEEE announced the formation of a new unit to develop new standards. Data transfer speeds are estimated to be 475 Mbps (requiring higher speeds at the physical layer), which should be 45 times faster than the new standard, and about 8 times faster. It will also be transmitted to a longer distance than the previous wireless network.

The version of the protocol being developed by the mainstream vendors (Qualcomm, Broadcom, Intel, etc.) uses the 5GHz band (also known as the 6GHz band) and uses: wider baseband (up to 160MHz), more MIMO, and high-density modem (256 QAM). Theoretically, 11ac can provide 1Gbit of bandwidth for multiple site services, or 500Mbit of transmission bandwidth for a single connection.

There may be a speed limit, not very clear.

Wireless routers send signals across the board, and the closer the router is to obstacles, the more easily the signal is suppressed. Therefore, you should choose a high and spacious location in your home to place the router so that the signal can radiate downwards and reduce the blocking of obstacles and signal blind spots.

Routers transmit data information in the form of data packets. Electrical appliances, glass, and metal items will cause obvious interference to the signal, resulting in transmission blockage. Friends can keep the router away from the above categories of items to reduce interference.

1. If the router version is older, then regularly updating the firmware can ensure that the software of the router is in a good and efficient operating state.

2. If the wireless router at home has been used for too long, it will be a good choice to replace it with a new dual-antenna or multi-antenna router.

1. Buy a wifi repeater: plug the repeater into the socket at home, and the signal range and strength can be enhanced after debugging.

2. Reuse of old routers: Set the old router to AP mode, and then connect to the existing main router through the LAN port to expand the signal.

3. Adjust the antenna: Most router antennas are placed in a "ring", and in the vertical direction, the signal coverage will be wider. The antenna can be adjusted appropriately according to the distance and angle.

Usually the router is factory set to mixed mode with a set rate of 75%.

1. Adjust the rate: The partner can enter the security settings and adjust the rate of the router to the maximum.

2. Select Single Protocol: Set the mode to use only protocol.

Open the browser, enter the router address and username and password, check whether there is an unfamiliar device in the corresponding menu, and compare the IP address with your own hardware.

Then send the friends three magic weapons to prevent rubbing the net.

1. Set a complex password.

In the Tab or Security, select the WPA-PSK WPA2-PSK password and set a complex, easy-to-remember, and hard-to-guess password.

2. Disable the DHCP function.

In the Local Area Network (LAN) settings, disable the DHCP function to prevent automatic IP address assignment to wireless clients.

3. Change the default IP address.

If it defaults, it can be changed to prevent easy guessing.

Router reboots, most routers have limited memory or ability to process information, reboots can periodically clean up the router's cache.

2.Set according to the angle of the router antenna on the manual, the wrong angle of the antenna of the wireless router will cause the wifi signal to be poor.

3.Place your wireless router in an open space so that the wifi signal doesn't pass through many walls and doors as much as possible.

4.You can choose to change to a new dual-antenna or multi-antenna router, as the use of a wireless router for a long time will cause poor WiFi signal.

The wifi network speed at home is slow, as long as you modify these numbers on the mobile phone, the wifi speed will increase immediately.

1. The speed of the wifi network is determined by the broadband rate, but the slowdown of the wifi network speed is generally caused by the data congestion of the router. If there are too many devices connected to WiFi at the same time, the router needs to receive and send data to each device at the same time, resulting in a decrease in its own efficiency, and it is easy to overheat due to excessive load, which in turn leads to the degradation of router performance.

2. If there are not many devices (less than 10) that use wifi at home, it may be that wifi is rubbed by other devices, you can log in to the management background of the router to view and prohibit unknown and suspicious devices that rub the net. If you have a large number of devices that use Wi-Fi at home (for example, you need to have multiple smart devices connected), you can choose a high-performance router that supports more than 100 devices.

Is it to see if the network is good or not, and whether the power of the router is enough? It's not enough to buy a new one, it's okay to buy a new one, it's okay to have a higher power. The main thing is to look at the network, whether the network is good or not, and the network signal.

Check if the speed limit has been set, and change the login password of the router.

not the wifi password) and then change the wifi password.

Pay attention to whether the WPS or QSS function is turned on, if there is, you must turn it off, because this function will produce a PIN code, which is cracked out even if you change the wifi password, it is useless, and now the network technology tends to be civilian, and these common means of high town should be guarded against.

It's best to restart the wifi again

There is a certain limit to the speed of the home wifi or Ninki.

It mainly depends on which wifi you are connected to

The speed of 100M is 280, which is more than 7000KB and the bandwidth is 200M.

Place the router in a spacious place, away from a wall.

If the router is as high as possible, the downward signal will be slightly stronger.

Adjust the rate of the router In fact, the routers we bought back are mostly set to run at 75% of the rate, many people do not realize that the front is at this point, in fact, we can adjust and increase the speed of the router, adjust it to the maximum silver reputation carry, and set the router to use only the protocol, and most wifi are using mixed mode, using a single virtual merge protocol will double its performance.

The easiest way to do this is to restart your phone, or toggle the airplane mode to re-receive the signal and refresh the network speed.
