Bad Wi-Fi signal? That's what you didn't use right

Yesterday, there was always a bad signal from a small partner to ask for advice on their own wireless network. Obviously there was a signal but the speed was not going. Ask what to do. If the mobile phone signal is not good, it is the mobile operator's business, Xiaobian is no way, but many people complain that the Wi-Fi signal is not good, this Xiaobian has ideas.

First of all, search for “Wifi Analyzer” APP on the mobile phone to download and install, and run the application to see the current wireless signal conditions. In simple terms, the higher the peak signal in the graph, the stronger the signal, and the shorter the signal, the worse the signal. In the horizontal direction, you can see the bottom row of numbers. This part is the channel occupancy situation. The more overlapping the channels, the more severe the failure. Even if the connection is used normally, the absolute speed will still be greatly disturbed.

At this time, it is very important to find a channel with the least interference, or at least the equipment used. Or Wifi analyzer this application, slide the screen to the left, switch to the same figure with Xiao Bian, select your own Wi-Fi, the application can quickly scan and recommend the appropriate wireless channel.

Well, now it is back to the router, log in your own route to modify the settings. Logging in to the router is actually entering the appropriate address in the browser's address bar and entering the username and password as prompted. If you do not know this, you can turn over your own router. The default address and username and password are oh.

Login to the router and find the wireless settings, usually in the basic settings (slightly different for each brand of router location), in the "channel" select just Wifi analyzer recommended channel, such as just Xiaobian test is 14,13 12 channels is better, so choose 12 according to the situation.

As a result, signals can be used at full speed in places that are accessible but have serious interference. Note that what is specifically said here is accessibility. Whether it is a concrete wall with a brick-concrete structure or a wall with reinforced concrete, signal failure after passing through the wall will not be improved!

Modifying the channel can only improve the quality of the connection in the case of multiple signals, instead of determining the signal strength and the ability to penetrate the wall. The quality of the signal also depends on the wireless RF power and the antenna. The maximum household power of radio frequency power products must not exceed 100 milliwatts. This is a national mandatory standard, but in general, this power is sufficient (small series are manually changed to 50 milliwatts, the signal is no problem). Then there is the gain antenna. First of all, a lot of people have no sense to feel that they should change stronger antenna, but for a constant national standard RF power, the gain antenna is not meaningful even if it changes 9dBi. If your router is equipped with only 3dBi, consider replacing it with a 5dBi booster antenna which is sufficient.

Finally, if possible, it is recommended that you replace the router with 5G signal. Whether it is 802.11n 5G or 802.11ac 5G can be, although the ability to wear through the wall is slightly worse, but the win is less interference.
