One, the current family for wireless router + notebook + desktop use, if the desktop and notebook and wireless router in a room, but the phenomenon is also very frequent drop line.
If you connect to a router's desktop, dial-up stability, long work does not drop the line, then you can judge the fault may come from the wireless router, we can improve the quality of the router's power, heat, and so on, if the problem has not been resolved, we have to speed limit, the average distribution of two co
In general, the process of CDMA network optimization is divided into three stages: single base station configuration confirmation, community optimization and system-wide optimization (or global optimization), each phase completes different tasks.
Single Base station configuration confirmation
The goal is to confirm the installation integrity of the BTS and the accuracy of the data. The verification parameters include:
(1) The Base station equipment debugging: the base station equipment debugg
PoE + switching devices, and depending on the supplier, it is very likely to increase the budget for other aspects, for example, each PoE + port ranges from 600 to 1200 RMB (retail price) to network construction.
Make 802.11ac smarter
Ruckus has been working hard to solve power supply problems to ensure that our fully functional 11ac products work seamlessly with existing 802.3af PoE switching devices.
Because 802.11ac requires different chips,
1. Wireless Networking
Networking requirements: Establish a network without a line in the LAN to share resources among devices.
Networking Mode: place a wireless access point in the LAN center and add a wireless network card to the Internet device.
2. Point-to-point connection
① Wireless connection between a single machine and a computer network
Networking requirements: achieve wireless connection between remote computers and computer network centers
Networking Mode: Add a wireless access point

For the duplex room, try to place the wireless router in the center of the room
So how can we identify such a central location?
In fact, the simplest way is to observe through your line of sight, that is, where you can see the most room scenarios, then this
Wireless LAN technology has become the focus of all people, so what are the different requirements and instructions for wireless network networking methods? There is a networking method suitable for you through the following introduction.

I. Questions about enhancing wireless signals
As you know, wireless signal loss may occur due to transmission distance, media, or other factors, shortening the transmission distance and reducing the transmission speed. Therefore, to improve the wireless transmission performance and improve the wireless routing signal, you can start from the following aspects.
◆ High-gain antenna preferred
Both wired and wireless networks have signal attenuation. Compa

Showing the Garmin ga27c GPS antenna, we can see a piece of ceramic patch on its PCB board:Garmin GA-27 active
interference
If the noise intensity of your network bandwidth exceeds the -85DBM, then RF interference is likely to impair network performance. In this case, the user's retry rate will exceed 10%, and the user will feel the network speed is affected. This can happen, for example, when a wireless user is in the same room as a running microwave oven. If you decide that the problem is caused by radio frequency interference, you have to find out where the interference comes from and try to remove
present, wireless routers in the indoor launch power generally does not exceed 20dBm. The higher the transmitting power of the wireless router, the higher the signal strength, but more than the specified range will cause large electromagnetic radiation and interference.
Antenna gain: The greater the gain, the stronger the signal strength, at present, most of our routers antenna gain 3dBi.

router until you hear a "click" of a network card. Now that the "one wireless router" and "one broadband network cable" have been successfully connected, the process of installing the wireless router has already been completed, and then let us know about the wireless router.
In addition to what we have just mentioned, wireless router, a number of network cable interface, a wireless router also has a power interface, as a network equipment, wireless routers need independent power supply, that i
When the router is published, there are some technical terms, such as 802.11AC, 5G, gigabit, dual frequency, 2*2 antenna, Wi-Fi, and also the conclusion that "10 times times Faster", "Top Configuration", "Global X". Under the manufacturer propaganda, some people think that the product is good to be bad, also some people think the manufacturer is bragging x. This article is the wireless router knowledge popularization, each followed by a selection of s
, the entire system is typically a wireless system, such as the Code division used in multiple antenna systems, 3G mobile phone systems (wireless systems) multiple Access (CDMA) systems, even DSL systems (wired systems) that generate crosstalk (crosstalk) using multiple phone lines.
This paper will first introduce the history background and operation of MIMO, and discuss the extent to which MIMO can extend WLAN transmission range.

sources to interfere, which naturally causes the WLAN transmission speed slows down. In addition, wireless network transmission distance is limited, although the general wireless router nominal transmission distance can reach 100~300 meters, but in the actual use if there is a barrier, this distance will be shortened dramatically and will lead to slow data transmission speed.
Knowing the slow speed of transmission, we can begin to solve the problem with a targeted approach. First in the layout

Knowing the slow speed of transmission, we can begin to solve the problem with a targeted approach. First in the layout
the RF signal of the radio transmitters output is transmitted to the antenna via a feeder (cable) and radiated out by the antenna in the form of electromagnetic waves. When the electromagnetic wave arrives at the receiving location, it is received by the antenna (only a small fraction of the power is received) and sent to the radio receiver via the feeder. Ther

Therefore, I prefer to purchase a Mbit/s router or a Mbit/s router. After all, the network device update iteration is slow and a vro takes a long time to use, it is necessary to leave room for network bandwidth upgrade in the future. Of course, for users with simple network needs, a low-price M router is also a good choice, and there is no best product in the world, if you make the best of your resources, you are the best choice. blindly pursuing performance leads to performance redundancy, wh
Check that there is a mobile phone signal amplifier in the market. I don't think it's too expensive. The poor have to find a solution, so Baidu and Google have joined hands to save money and solve the problem! Finally, I found a way to enhance the mobile phone signal with chopsticks and tin paper. by sorting out similar data, I found this method, and then I bought two pieces of tin paper and chopsticks, I tried it several times, but it still seems to be effective!
