I can't connect to my Wi-Fi network

Wi-Fi basics

• SSID: this is the name of the Wi-Fi network. SSID is just a name to identify the network. Sometimes it includes trailing "_2.4G" or _5G" to tell what frequency it is but it is still just a name.

• Frequency band: This is the frequency of the Wi-Fi signal. There are multiple, but the original is 2.4 GHz and then there are 5 GHz, 6 GHz and onwards. New standards keep coming. The most common at the time of writing this is 2.4 GHz and 5 GHz. 6 GHz is starting to become more and more common. Sometimes an SSID name gives away which band it is, sometimes not.

• Authentication: in layman's terms, this is what happens when one log onto the Wi-Fi network. The most common way when connecting a random device to a public network is to simply provide the Wi-Fi password when prompted. No user name is required. This method is called WPA2-Personal. Other methods, like e.g. WPA2-Enterprise also exist. Read more here: https://en.wikipedia.org/wiki/Wi-Fi_Protected_Access

• Captive Portal: A Captive Portal is when one select to go on a seemingly unprotected Wi-Fi and gets redirected to a dedicated website where one is required to input both name and password. This is typically the solution for hotels' Wi-Fi.

Issues that may arise

Reader 3 and Lingo 3 supports frequency band 2.4 GHz and authentication WPA2-Personal.

If the router does not support this band and this authentication method - it is not possible to log on to that specific Wi-Fi.

Reader 3 and Lingo 3 does not support the use of Captive Portal.

Solutions

Frequency band

It is very rare that a Wi-Fi network and routers does not support 2.4 GHz, but in some cases network admin may decide to deactivate the 2.4 GHz band and run on higher frequencies only. If you have the opportunity - talk to you IT admin to resolve it.

Authentication

If other authentication than WPA2-Personal is used, including use of Captive Portal, it may be possible to allow Reader 3 / Lingo 3 to get connected anyway by whitelisting its MAC address in the router. This need to be done by the network admin and success may depend on the network's general security settings. It as to be tested case-by-case.

The MAC address of Reader 3 and Lingo 3 can be found in Settings\System information.
