Connect to a Wireless Router without a WPS Button
Follow these steps if your wireless router DOES NOT have a WPS button or the Connect to a Wireless
Router with a WPS Button procedure was unsuccessful. This is referred to as Manual pairing. There are
two sets of instructions, one for Apple devices (iPhones or iPads) and one for Android devices
(smartphones or tablets running the Android OS 6.0 or later).
Manual pairing using an Apple iPhone or iPad or PC Notebook:
1. Items needed:
a. An Apple iPhone or iPad.
b. The wireless password or passphrase for your router. Password or passphrase must not
contain unacceptable characters (see acceptable Special Character chart in FAQ
section.
c. The SSID of your wireless router (look on the side or bottom of the router or consult its
manual)
d. A strong WiFi signal (at least two bars) from the router where you want to install the
FILTERSCAN WiFi monitor.
2. See Figure 12 to locate the FILTERSCAN WiFi Air Filter Monitor WPS button.
3. Depress and hold the WPS button until the WiFi Status Indicator blinks green then fast red. This
usually takes about 5 seconds, but may take up to 30 seconds. Release the button as soon as the
fast RED is seen and wait until the WiFi Status Indicator blinks amber.
