Wi Fi is a lot slower than wired! Wireless is much slower than wired, why

Is the system speed limiting, xp system.

Start --- running --- Group Policer program (. In Local Computer Policy, step through the Computer Configuration Administrative Templates Network QoS Packet Scheduler branch. On the right side of the screen will appear the QoS Packet Scheduler policy.

Then click Limit Reservable Bandwidth for the subproject on the right. In this case, a detailed description of "Limit Reservable Bandwidth" will appear on the left. Here we can learn some basic scenarios for "limiting reservable bandwidth".

Once we understand this, we can set the "Limit Reservable Bandwidth". Click "Properties" next to "Display" under "Limit Reservable Bandwidth" (or select the sub-item "Limit Reservable Bandwidth", and then right-click "Properties"), the "Limit Reservable Bandwidth" dialog box appears, click "Description" first, and then learn more about "Limit Reservable Bandwidth" to determine the percentage of connection bandwidth that can be retained by the system. After that, we can go into the settings for the other 20% of the bandwidth.

Click on "Settings". "Settings" gives us three options (not configured, enabled, disabled), select "Enabled", then set the % next to the bandwidth limit to 0%, and press OK to exit. That's it.

It is possible that the driver of your wireless network card is installed incorrectly, or the wireless network card is damaged.

However, this usually does not happen, because the speed of the wireless network card is much faster than the network speed.

Now the more popular is and.

High-speed WLAN protocol using the 5G Hertz band.

The maximum rate is 54Mbps, and the actual usage rate is about 22-26Mbps, which is currently the most popular WLAN protocol, using the Hertz frequency band.

The maximum rate is 11 Mbps, and the actual usage rate varies depending on distance and signal strength.

1-2Mbps within 150 meters, 11Mbps within 50 meters) WLAN-based QoS protocol, through which B and G are capable of VoIP.

In other words, it is a protocol that realizes the voice call function through a wireless data network.

This protocol will be a powerful way for wireless data networks to compete with traditional mobile communication networks.

is an extension on the same frequency band. Supports up to 54Mbps speed.

Compatible. This standard has already outspoken to become the next step in wireless data networks.

Yes, the expansion is intended to be compatible with other standards in the 5G Hertz band, such as HyperLAN 2 used by the European Union.

It is a new wireless data network security protocol, and the vulnerabilities in the WEP protocol that have been popularized will become a security risk for wireless data networks. A new TKIP protocol is proposed to solve this security problem.

Is it wireless that limits the speed.

If the wireless transmission is much slower than the wired transmission, the possible reason is: the wireless network card signal is not good or someone is rubbing the network.

1. The signal of the wireless network card is not good.

If it is a wireless transmission, there will be a problem of signal attenuation and hotspot signal strength caused by a barrier rock. The router transmits very limited power and can only receive data normally in the room. If the partition wall or the interval is far away, the transmission speed will be slow due to poor signal.

In contrast, the attenuation of the network cable is much weaker.

2. Someone rubbed the net.

Thanks to the relative openness of the wireless network, people near the wireless network hotspot can use the wireless network to access the Internet if they crack the password. The network bandwidth is occupied, which leads to the situation of getting stuck in the Internet. Wired networks, on the other hand, do not exist.

The factors that contribute to slow internet speeds are complex, and the main reasons may be:

1. The signal strength of the local CDMA network is weak. Judgment method: The signal of the network card is less than 4 bars (the strongest signal is 5 bars), and you can also roughly judge whether it is due to the slow speed caused by weak signal strength through the signal strength of your CDMA mobile phone.

Solution: Change the location, for example, move from indoor to outdoor, and see if the signal strength is enhanced, 2. The system or anti-virus software is automatically upgrading or updating the network. Judgment method:

Close all Internet access programs (Internet Explorer, MSN, QQ, etc.) and find that you are still sending and receiving data. Solution: Wait for the end of the update (it is recommended to access wired broadband for **, the speed will be faster), and then turn off the automatic update of the operating system (Control Panel - Automatic Update - It is recommended to select "Notify me when available**".

option) and the antivirus software's auto-update virus database feature.

3. The computer has been infected with Trojan horses and other viruses. Judgment method: After closing all Internet access programs (Internet Explorer, MSN, QQ, etc.), the sent data is still large and the value is increasing, while the received data changes very little.

4. The server speed is slow. Judgment method: Due to bandwidth limitations, foreign ** and small** will generally be slow, which is a normal phenomenon. Solution: It is recommended to use the homepage of Sina, Sohu and other domestic ** for testing.

5. I don't know the speed of CDMA1X wireless Internet access, or I am used to broadband access such as ADSL and optical fiber, and I feel a little slow at first. The theoretical speed of CDMA1X wireless Internet access is equivalent to three times that of dial-up Internet access, and the actual use can reach about 60-80K S, and the ** speed is about 2-20K S (due to the fact that it is related to the ** server speed, it fluctuates greatly, and the normal situation can reach 5-10K S). This speed is enough for general Internet access, sending emails, and playing online games.

Wired broadband such as ADSL is not necessarily faster than wireless Internet access if the number of people sharing it is slightly larger.

If you are using an OPPO phone and the Internet access is slow after connecting to Wi-Fi, please troubleshoot the Internet from the following scenarios:

1. Slow home network access:

a. Please check whether the current router has a speed limit, if so, please set it again.

b. The operator has a limited speed, consult the operator to restore the network speed.

2. Slow Internet access on public networks

a. Public network, with a large number of users, will slow down the network speed;

b. Some public networks have speed limits and other restrictions, so it is recommended to use the network at home to observe and try.

3. Slow Internet access under weak signal:

a. It may be far away from the router or a partition wall, resulting in weak signal strength and reduced network speed, it is recommended to try close to the router;

b. The use of metal protective case will have an impact on the mobile phone or tablet antenna, which will cause the signal of the mobile phone or tablet to deteriorate and slow down, so it is recommended that you use a plastic or leather protective case.

4. Slow Internet access after connecting Bluetooth devices such as Bluetooth headsets or Bluetooth speakers

A. Bluetooth and WLAN work on the frequency band at the same time, if the Wi-Fi connection is a frequency band network, there will be interference between the two, please turn off Bluetooth to try;

If none of the above methods can solve your problem, please bring the purchase invoice, warranty card and mobile phone to the nearest OPPO customer service center for testing and processing. (You need to back up important information in advance and contact the service center in advance to explain the relevant situation).

The router has not been restarted for too long, you can try restarting the router.

If it's still very slow, you can call the operator's ** and ask them to overhaul it.

Buy a new router and wear it through the wall a little bit more and you'll be fine.

There are two types of situations:

1. Channel interference problem: There are too many nearby routers, and the automatic default channel is generally 6, check and search whether there are many nearby routes, it is recommended to change the channel to 11, test it.

2. QoS speed limit, or broadband speed limit, please log in to the router to view, if you have not touched any settings, it is likely to be a channel interference problem. Adopt it.

It should be that the router has too many connected users.

The router problem may be that your router's communication protocol is relatively old, and the wireless bandwidth can't keep up with your wide-area bandwidth, so change it to 300M.

Knowledge of mb s mbits

The meaning of MB S is megabytes per second, and the meaning of MBIT S is megabits per second, the former refers to the number of bytes transmitted per second, and the latter refers to the number of bits transmitted per second. The letter B in mb s is the meaning of byte, although it is the same as the bit translation in mbits, both are bits and data measurement units, but the two are completely different. byte is the number of bytes, bit is the number of bits, and every eight bits in a computer is one byte, which is 1 byte 8bit, which is 1:

8. So 1mb s is equal to 8mbit s. Therefore, when writing the unit, we must pay attention to the case of the B letter, especially some people also abbreviate the MBIT S as MB S, at this time, the size of the B letter can really be called a millimeter, a thousand miles wrong.

The WLAN family is the most widely used. Since the implementation of the standard in 1997, there have been other standards formulated or brewed, in terms of transmission rate, the transmission rate of WLAN can be increased from the current and provided 54Mbps to 300Mbps or even as high as 600Mbps.
