Sometimes you will not see the network name (SSID) you are looking for in the network list. This issue may be intermittent and sometimes that network will display and other times it will not.
This was an issue with LabQuest versions below 2.3.1. To resolve this issue, update LabQuest App to the latest version. A free update is available at: http://www.vernier.com/support/updates/labquest/labq2/
TIL 3807: Will LabQuest 2 work on a 5 GHz-only network?
Note: Hidden networks will never display in the network list. You need to choose “Join Other Network…” for those networks, which also require you to enter the SSID and passphrase (both are case sensitive).
