Now due to

, We have been providing real exercise for our home network. But are you taking full advantage of the potential of internet and home broadband? I've been there

15 years: This is how I make the wireless network work at its best.

Most organizations are committed to future work. In this brave new world, what determines failure or success?

If your ISP provided you with a cable modem or residential gateway five years ago or more, you may want to consider replacing your hardware. In the past few years, Wi-Fi standards have evolved considerably, and your device may support newer standards than routers/access points. 802.11g (launched in 2003) has a maximum transmission speed of 65Mbps and only supports a single antenna/transmitter with a total bandwidth of 20Mhz. 802.11n (launched in 2009) is a dual standard of 2.4Ghz and 5Ghz, supporting 40Mhz and 80Mhz channels. 

Depending on the capabilities of the client hardware with which it communicates, the latest 802.11ac and 802.11x (Wi-Fi6) standards can use 160Mhz channels, using multiple beamforming antennas and transmitters (MU-MIMO) to transmit data. This can only be achieved using modern Wi-Fi chipsets supported by smartphones, tablets and laptops launched in the last three years.

Cable modem technology has also been improved, and because of multi-channel support, DOCSIS 3.1 can support transmission speeds of 1Gbps-so please call your ISP and determine if you can increase your broadband speed. In order to support it, it may be necessary to upgrade to a higher level of service.

For old devices that cannot be easily replaced (such as low-power IoT smart plugs and switches), a 2.4Ghz network may be your only choice. However, the combined use of 2.4Ghz and 5Ghz networks is an ideal choice to reduce channel congestion, especially when you live in multiple residential areas (such as apartment buildings) at the same time broadcasting many SSIDs.

If your device supports the 5Ghz band, be sure to use it, there is no benefit in using an older band, as it has to compete with other 2.4Ghz devices on the very saturated spectrum. However, keep in mind that the 2.4Ghz and 5Ghz bands behave differently-2.4Ghz has a longer range, slower speed, and has better mobility through 5Ghz semi-permeable barriers (such as rocks). 

Although you may want to hide the router or AP behind furniture or cabinets, don't do it-otherwise it will affect its performance. Put them on a table or TV stand and open them outdoors. If possible, install it as high as possible in an open area, for example using a wall mount. 

My access point has a wall bracket in the most open area of ​​my house.

Your broadband drop may be in the corner of your home, where the ISP dropped the fiber or coaxial cable, but this is not necessarily the best place to broadcast the signal in your home. If you have to use a longer Ethernet cable to connect from a cable modem or residential gateway to the AP that best broadcasts the signal, you can do so-the long Cat5 cable can be ordered online and can be easily in the attic or crawl space use.

Use the spare Ethernet port on the residential gateway/router provided by the ISP to connect to the AP or router (in AP mode). If there are not enough ports, you may need to buy a cheap Ethernet switch.

If there is no power outlet for the AP, please consider using a Power over Ethernet (PoE) compatible AP. You will need to buy one

For those APs to plug in, you can place them near residential gateways/cable modems and other network equipment/devices.

If you do purchase a secondary router/AP to supplement your network, make sure to turn off the 2.4GHz (and optionally 5Ghz) Wi-Fi radio on the residential gateway or existing router, because you don’t need multiple 2.4Ghz network broadcasts , It will only exacerbate congestion. 

If you cannot upgrade the residential gateway (because your ISP maintains/will not replace it), please consider buying

Or can be set as AP/Consumer wireless router

(Layer 2) mode. This is done through the application on the smartphone or the web user interface of the router or AP. 

Although many consumer routers can do this, such as Linksys and NetGear products, not everyone can ensure that they must read the manual online before using this particular model. Do not run auxiliary under any circumstances

(Network Address Translation-another router) is behind the original router, because this will cause many network connectivity and performance issues.

Just because you got a free cable to use certain devices ten years ago, and keep it in the huge Italian trash can, you think it will come in handy someday, but that doesn't mean you should use it. If the Cat-5 cable is old, frayed or scratched, replace it. Likewise, if the connectors inserted in coaxial cables and cable modems are bent or damaged, it can cause reflection problems and RF noise. If you see poor cable broadband performance, let the technology fix it and perform a line test and replace it. I felt the signal from the coaxial and optical cables weakened, and my provider was buried in the lawn, but was damaged by the outdoor staff of lawn mowers and other equipment. It happened.

Just plug it into the wall and it will work, and may be a correct and affordable solution for many people, but be aware that some devices will cut your throughput in half depending on the radio arrangement in the device. Essentially, they usually have to communicate with the 5Ghz or 2.4Ghz backhaul option to the main router.

The adapter can also be plugged into the wall and transmit wired Ethernet signals through the home's power supply. However, depending on the age and complexity of the house's wiring and the distance between the plugged socket and the socket with which it must communicate (they work in pairs), you will most likely not see any information close to the nominal transmission speed. 200-400Mbps. You may be close to 100Mbps or lower.

Using coaxial connections in the home to provide cable TV connections can effectively connect switches and Wi-Fi access points to different areas of the home, because they can provide Gigabit Ethernet speeds, but they are very expensive. You will need a router or residential gateway that supports MoCA, or you will need to purchase multiple adapters.

Is a group of access points that use multiple onboard Wi-Fi radios to communicate with each other, designed to intelligently switch and optimize connections with devices throughout the home. These include Linksys Velop, Amazon's Eero, Google Nest Wi-Fi and NetGear's Orbi. 


One node is connected to a broadband device (such as a router, a residential gateway or a cable modem), and other nodes communicate wirelessly with it to form a mesh network. Although mesh networks can be very effective, these nodes, like any other Wi-Fi access point, suffer from placement issues, and they work best when they are within sight of each other. If there are any obstacles, such as thick walls or multiple walls, they will lose connectivity or will not work at all.

If you can physically connect your main work computer to a wired Ethernet, directly to a router or switch, then you can definitely do it-it will always be faster. It will always be the most reliable connection. If your laptop does not have an Ethernet port, such as one of the newer Macbook or Microsoft Surface, please consider buying

, It provides multiple ports including Ethernet, USB-A, USB-C and HDMI output for external monitors.
