Exactly the same problem here.

I've encountered here some issues with people getting the same issue but being able to connect if the network is not password protected, being that is not really a valid option.

Also the response to make an "easier" password is clearly not good option, an although I have a relatively easy pass with no special caracters the issue remains. There is clearly some problem with this product if there are so many people having the exact same issue.

Hello @PinkSpider

It seems that  Huawei HG8145V5  have feature called Band Steering , page 6 of the UserGuide found online:  https://www.time.com.my/sites/default/files/uploads/Huawei%20HG8145V5%20WA8021V5%20-%20WiFi%20Setting%20Guide.pdf

• Try to switch off Band- steering  (also called ‘Smart Connect’ or ‘Whole-Home Wi-Fi ‘ on some wifi router) and see if bulb could connect to it
• As the smart bulb only support 2.4Ghz, try to use different SSIDs for router 2.4Ghz and 5Ghz (or use a different wifi name for 5Ghz)
• Important : Double-check the 2.4Ghz WiFi password you have put in when set up the bulb:  Go to Settings-> WiFi on your phone, Tap (or Long press  the router's WiFi name  ->Forget / Delete the network -> Please reconnect to your router wifi and it will ask for a password, will it accept your router password?

Hey @cmfm,

If bulb was able to connect to unsecured wifi on router, it could be related to the router security settings

I updated some troubleshooting on this related thread discussing the same topic, can you help confirm some details there or start a new thread for your concern, feel free to let us know how it goes  many thanks!

@Solla-topee hello! The SSID of my 2.4Ghz and 5Ghz are different, thus, band steering is turned off.

Hey @PinkSpider , thanks so much for sharing all the detailed info

• Try a different 2.4Ghz WiFI channel among Channel 1- 11
• Can you confirm you have put in the correct password. 
• Also ensure Tapo APP is up-to-date. 
• You may also try to set it up on a different phone if possible 

May I know the model of your phone and its IOS or Andriod version, can I have a photo of the Error on Tapo APP? Can I have a photo of the wifi settings on main router as well
