After about 5 years, 3 HS200 switches I had installed at the same time, the wifi functionality has died. The switch can still operate power, but it will no longer conenct to my local network even though it did fine for 5 years. Went throughll all the reset steps, and tried both wifi and bluetooth setup with no success. Now it looks like I have to replace them just because of this issue.

The step that fails is close to the end.

• I can successfully reset and hear the click.
• I can connect to the switch's wifi to link to my phone.
• I can then choose model and get to selecting a local network, but despite using this network for 5 years, it no longer can see it.
• I tried manually connecting several times, but it cannot see/link to my wifi.
• I have 34 other deviced connected to a dual band 5GHz/2.4GHz network, INCLUDING a set of Kasa strip lights in my recroom, which the app had no issues with. Only the switches fail.
• I tried rested the router completely. Did not help.

Can these switches really be this terrible quality to burn their wifi capability after 5 years? Seems way too early.
