There are different WiFi standards that use different WiFi Frequencies. All your equipment must be able and configured to operate on the same frequency band (ie. a 2.4GHz device can't talk to a 5GHz device). The LCS WiFi Users Guide is very lacking on any of the WiFi specifics, but it seems that it operates only with 2.4GHz frequency bands with WPS security. Generally speaking, a good number of current WiFi devices on the market support both 2.4GHz and 5GHz modes (even at the same time!). However, I have found many non-technical users assume 5GHz is bigger number and therefore better, unknowingly disable the 2.4GHz band and then get stymied when their older WiFi printer no longer connects (as it only operates on 2.4GHz) or other devises have not been re-configured for 5Ghz communications.
It all essentially loosely boils down to trying to use an AM radio to to communicate with a new-fangled FM broadcast. If supported, you can switch your AM radio over to FM, or get a new radio that has an FM mode.
Note: WiFi is technologically large topic and there are many many nuances and the above is a nonspecific simplification.
