HS105 units don't auto-reconnect after losing WiFi connection
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I have four HS105 units and one HS107. Some of the HS105s very frequently lose their connection with the WiFi. Mostly it is the two which are in a different room than my router, but sometimes even the ones in the same room as the router lose connection. In fact, right now all four of the HS105 have lost connection; only the HS107 is online.
I can understand them losing connection from time to time but I would think they would automatically try to receonnect with the router. They don't do that; once the connection is lost they don't reconnect by themselves. If I unplug the Smart Plug and plug it in again, it joins the network just fine. I have to do this about every other day.
The HS105 are all at firmware version 1.5.1, hardware version 1.0. The one which is the furthest away from the router shows a signal strength around -64 dBm.
Is there any way to make these devices auto reconnect with the router?
So far, I haven't had this problem with the HS107. It is hardware version 1.0 and firmware 1.0.5. I can't find signal strength for the HS107 in the app.

RESOLUTION: I'm putting my resolution here so you don't have to read through the whole thread to find out what happened.
On or about 2019-01-16 I received beta firmware version 1.5.3 for the HS105s. Since installing that I have not experienced this problem. I have only occasionally seen the plugs lose connection since then, but they do auto-reconnect now. So at least for me the auto-reconnect problem was fixed by firmware 1.5.3.
BTW, my HS105 units are now running firmware 1.5.4.

I came here looking for help for exactly the same problem, new HS105 devices that keep losing wifi connection and won't reconnect.
My wifi is fine, all other devices in my house are working fine. Given that people are reporting this issue since 2018 and this is now 2020, I conclude that I have been scammed by buying these and will return them. This isn't rocket science, people.

Same issue: HS105 units loose connection daily. They have to be removed and re-installed every time to re-connect. I saw the note about firmware upgrade ( at 1.0.21), but the app says no update available. My WI-FI is strong. This is a fraud!

I have the same issue. I have 30+ Kasa devices and it's maddening to not have them work after a router restart. I have a netgear orbi mesh and my other devices seem to be ok. My Kasa devices, however, come on one or two every 20-30 minutes after a router reboot.
I put a battery backup on my router so I don't lose power. That's decent insurance, but when an inveitable firmware reboot occurs, all the devices go offline. There needs to be a way to go into the Kasa switches and plugs and tell them to release their IPs and get another one.
Also, can anyone at TP-Link advise on what the lease length is on the Kasa devices? That would be great to know! Who know when/if they will come back!

Anyone know how to fix this issue? I am about throw away the damn plug and never buy anything made by TP link again.

@Thematrix310 how many of these switches do you have? I have 30+ and was having the same problem. I was able to determine the issue was due to all my devices requesting IP addresses at once thereby overwhelming the dhcp server in my Orbi router.
I resolved the issue by giving the switches dhcp reservations (ie static IPs). This resolved my issue.

@elhajj33 They never reconnected for me. Switched to sonoff devices. Easy to program. No issues. Works well with Home Assistant.
