The reason for the significant decrease in the speed after 11n encryption is given after all tests are completed.Test result of TP-Link M wireless route under unencrypted ConditionsLet's take a look at the single pair downlink test results of the M wireless router under non-encrypted conditions. We can see that, under unencrypted conditions, its single
the number of supported MAC addresses, the higher the general price. We recommend that you select a cisco Gigabit Switch with 16 k mac addresses.
After-sales service
Because cisco Gigabit Switches differ greatly from common cisco Gigabit Switches in terms of price and technology, the level of after-sales service is crucial. When purchasing a cisco Gigabit Switch, we also need to compare the quality of after-sales services of each brand, including three-pack services, on-site services, product m
I. Lan features:
LAN has the following features:1. high transmission rate: generally 1 Mbps-20 Mbps, optical fiber high-speed network can reach 100 Mbps, 1000 Mbps2. multiple types of transmission media are supported.3. Generally, the network adapter completes communication processing.4. Good transmission quality and low error rate.5. A rule-based topology.

Multi-channel lpcm: the original format of lossless audio tracks. It is equivalent to a wave file and does not require decoding. You can directly input a Power Amplifier for DA conversion. Because of the large bit rate and volume, in the DVD era, audio tracks are usually used in two-channel music discs. When the Blu-ray disc is used, the transmission rate and capacity increase dramatically, giving the oppo
, 3COM, CISCO, Siemens, Alcatel, Paradyne, have successively launched ADSL products and are committed to the development of ADSL; many telecom companies and ISPs around the world have also promoted their respective ADSL Services. North America and Singapore are the first to officially open their business. Japan, South Korea, and other countries have entered the trial phase, china Telecom has carried out relevant network tests in Beijing, Shanghai, Guangdong, Fujian and other places and started t
order to spare microcontroller pins, additional logic and make the PCBs simpler–in order words, to lower the costs– Philips Labs in Eindhoven (the Netherlands) invented the ' inter-integrated circuit ', IIC or I²C protocol that only require s 2 wires for connecting all the peripheral to a microcontroller. The original specification defined a bus speed of up to Kbps (kilo bits per second). The specification was reviewed several times, notably introducing the In 1995 And–since 1998, 3.4

Symptom: A company intranet is a 100Mbps network that connects to the Internet via ADSL broadband. The ADSL modem is connected to the 10/100 Mbps switch, and the switch is then connected to the server. When the connection is good, the PPPoE protocol is not available to computers in the company intranet.
Failure analysis and exclusion: according to the symptom analysis, the PPPoE protocol may not be able to find the ADSL signal under the

Ethernet switches are still commonly used. So I studied the enterprise-level Ethernet switch solution and shared it with you here. I hope it will be useful to you. As the main connection device of the LAN, the Ethernet switch is one of the fastest-growing network devices. With the continuous development of switching technology, the price of Ethernet switches decreases sharply, and switching to the desktop is the trend of the times.
If you have a large number of users, busy applications, and a v
The following articles describe in detail the functions and principles of Ethernet switches. For some users who have just come into contact with this industry, the term "Ethernet switches" is a strange thing for them, after reading this article, we will provide you with relevant benefits.

. This type of switch can be connected by the interconnection lines between the switches to provide more ports. The interconnection lines between switches can be created on any port on the fiber channel switch. However, if you plan to use products from multiple vendors, you must ensure that the devices are interoperable.

In terms of speed performance, CDMA 1X is the most outstanding. Although it is still far from the theoretical peak, it has exceeded the 56 K external Modem, and the speed is completely acceptable. Comparatively speaking, GPRS performance is lacking, probably because China Mobile's network load is too large, and its speed decline is very obvious, or even worse than 56 K Modem.

that I was still hyping "over five categories" last year, and this year, with the introduction of the Gigabit Ethernet standard, cabling vendors have also successively launched "6 categories" or "7 categories" cabling systems that support Gigabit Ethernet. It is certainly a good thing to launch advanced products, but I would like to remind Chinese users not to be overwhelmed by the hype of the manufacturers. when choosing a wiring product, consider it calmly, whether such a high-end Integrated

frequency division multiplexing technology to divide common telephone lines into three relatively independent channels: telephone, uplink and downlink, thus avoiding mutual interference. Generally, ADSL can provide up to 3.5Mbps uplink speed and up to 24 Mbps downlink speed without affecting normal telephone communication. According to the technical features of the ADSL Broadband Service and the user's telephone service, the two are separated in term
