Can you use a friend's windows PC? I'm on 1.2.1, with no problems.

The claim by TP-Link Smart Plug Support that you need a Windows PC to install new firmware may not be always right. I'm in an all Apple's home and just replaced two early version Wemo Smart Plug (Mini) that lost connection to Wifi, with which I was unable to connect it to my home Wifi during multiple re-install attempts after factory reset.

My replacements are TP-Link HS105 Smart Plug Minis. After a successful setup, right after I customized the plugs name, I was prompted to and completed a firmware update. After the setup right in front of my router, I moved the HS105 to a wall socket about 10-11 feet from the router, on the far end of a wide entertainment cabinet with a 65-inch TV and all sorts of electronics. The HS 105 was unable to reconnect to my Wifi after relocating from 2-3 feet in front of the router to its intended location. That worked for my Wemo Mini Plugs for 2-3 year, requiring occasional unplug-and-replug to regain access by Alexa.

Since I have a second router cascaded to my primary router to cover dead spots on the far end of my house one storey up, I had confusion selecting the best router by its SSID since they have identical SSID and passwords, for both 2-4 GHs and 5 GHz bands. During the repeated factory reset and setup, the setup procedure did not prompt me to update the plugs firmware after it's done once.

As to my problem with the HS105 losing connection to my home Wifi when relocated after successful setup, I finally decided to do a setup right at its intended location. With the NetSpot app to shows me the difference in signal strenght from both of my routers, I picked the one (idental SSID) with the stringest signal, set it up properly, and found that I am able to control it from Kasa on my iPhone while raoming aound the house. I'll still have to wait and see if they recover easily after losing Wifi connection.

@jowilson520 Not sure of the different model #'s but i have the issue with all my mini's but the older bigger ones that you can't buy anymore are rock solid. At first I thought it was a conflict with the band steering on my modem so I put in a separate 2.4 hz  TP-link router just for the plugs which seemed to work for awhile but now I'm having the issue again .  I don't think it's my internet  connection as I am having  no issues with my Globe brand plugs or my bigger tp-link plugs  so I'm about to give up on the mini's and buy more Globe plugs which I didn't really  want to do because  TP links app interface  is much better than Globes .
