Be aware that Wi-Fi's "SSID" naming precautions and that they are sending around
Last time, I explained how to find an IP address and change the password to access the setting screen of the Wi-Fi router.These two points are information that can be said to be a fort, so let's remember the method.This time, I will change the SSID and the encryption key.
The 15th ssid explains the encryption key in detail, so if you haven't read it yet, please take a look.
前回解説の設定画面ログイン用パスワード設定に続けて、SSIDをオリジナルの文字列に変更する作業をするNormally, there is an item of SSID and encryption key in one screen of the setting screen, and it will be set as a pair.If you connect with wireless wirelessly, the connection will be cut off as soon as the "Settings" button will be pressed, so the Wi-Fi will be reconnected with a newly set value.I want you to read it together with the next encryption key setting explanation.
Let's set SSID [*1].This is not difficult just to fill in the original name in the setting item, but there are some points to note.First of all, up to 32 characters at the maximum half -width, the string of the half -width alphanumeric symbol is preferable.You can give a Japanese name, but depending on the slave unit, you may not be able to recognize it, so let's make it into half -width alphanumeric characters.
The display order of the search result is in the order of radio waves depending on the function of the slave unit side, or the order of symbols → numbers → alphabet in the alphabet.If you put a symbol or a young number at the beginning of the character, it will be displayed at the top in the surrounding area, and it will often become noticeable.Recommended if you want to make it stand out.
[*1] ... SSID stands for "Service Set Identifier".To be precise, it is an ESSID (EXTENDED SSID) that uses multiple IDs, so some models say Essid in the setting item.These two can be regarded as synonymous with individual products.In addition, another name BSSID (Basic SSID) is a character string that corresponds to the MAC address of the device.This cannot be changed.
バッファロー製品での設定画面例。ログインしたら［無線LAN］の項目をタップする［SSID 1］の項目でSSIDにしたい文字列を記入。こちらは2.4GHz帯のもの下にスクロールし、同様に5GHz帯も記入。区別できるよう異なるネーミングにするTP-Link製品にて「Tether」アプリを使った設定例。ログインすると［ワイヤレス］タブが表示されるので、SSID表示部をタップする［ネットワーク名］などが表示されている部分をタップするとSSIDの変更ができる記号を文字列アタマに付けると上位に表示されやすくなるThe first point of naming is to keep the surroundings and names from dubbing.Avoid strings that are identified, conscious of being displayed around.In addition to the real name such as "MURAKAMI", avoid the name of the equipment manufacturer, the model name [*2], the name that knows the specific place, the woman and the hobby.
It is not a reason that can only be done with SSID, but as long as the radio waves with a name are transmitted to the surrounding area, it is measured from three directions (if there is a condominium, such as a condominium), the strength of the radio waves is measured.The source of the specific SSID can be roughly determined. [*3]There are often eavesdropping busters programs on TV, but it is the same as how to look for it.It is the rule of thumb to prevent meaningful information.For example, if you attach "_l living_room" or "_Meeting_space" in a children's room or living room, the use location will be identified from the outside.
[*2] ... If you search using a tool, the device manufacturer will be determined from the MAC address (BSSID), but it is better not to include it in information that can be easily seen like SSID.It is abused when a specific manufacturer has a vulnerability.
[*3] …… Running a specific area with a car, etc., calling for a woard living method to collect SSID and position.Since Wi-Fi has appeared, it is now very easy to do with the appearance of smartphones.It is done to find the target Wi-Fi.
スマホを使い、3方向からSSIDの電波の強さをマッピングすると、簡単に位置を割り出すことができる。SSIDと位置は周囲に漏れていると心得ておこう2.4GHz band (IEEE 802.11b/g/n) and 5GHz band (IEEE 802.11ac/a) is displayed simultaneously on the slave unit if both are supported.These two are at the end 2.In the case of 4GHz band, it is easy to use if you can distinguish "_24g" or "_bg", and "_5g" or "_AC" for the 5GHz band.If you do not need to distinguish only one of them, you do not need to distinguish the name.If you have a frequency band that you do not use, turn it off.
In addition, if you do not want to register for the Google location information service described in the 15th edition, add "_nomap" at the end.
This time, the SSID was changed, but the settings should be done at the same time as the encryption key.I would like you to set it at the same time after explaining the next encryption key settings.
