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.

Hi All.
I'm thinking it has something to do with the WPA2 challenge and response cycle. here's a clip from my Ubiquiti AP log file

Brief update on my own experience:
My unit 3 (same room as router) went red just before christmas and I left it alone to see if it would do a periodic test and recover, and now as of the 29th it's still red. A power cycle will no doubt make it go green as usual.
Some time around about the same time it went red, I had to re-enter my wifi password into my TV for some reason. All other devices were fine including the other 2 tp-link plugs. That may be unrelated, or maybe there was a wifi hic-up of some sort, - but my other 2 tp-link plugs stayed green. I see 2 issues - Firstly why did unit 3 go red when the other two stayed green. and more importantly, why did unit 3 not periodically try to reconnect without me having to cycle power?
I will power cycle to reset it and post any future failures or observations...

@MarkNI I waited 4 weeks and it never came back! Unplugged and it was back. Message from TP-Link support blamed my router. ASUS RT-AC88U in a mesh system. No other devices are having this issue. Due to this issue I have stopped purchasing Tp-Link devices and I have slowly switch over to different Sonoff units. They work on my Home Assistant system, they accept custom firmware, they don't need a vendors cloud, they reconnect everytime and they are cheaper.

@Mauly Does your device turn orange and not try to reconnect? Mine stays disconnected and will not reconnect unless I unplug it.

@bschatzow have you updated firmware to the latest version for your particular devices? My HS103's had this same issue and it was driving me totally nuts. Finally saw a mention in this thread of updating firmwrae ... I had looked and not found the setting for this before someone mentioned it was among the settings for the app ... I had been looking for it under the device options for each specific device ... once I applied the update, my devices have remained online. Won't know for sure that this was the solution until a bit more time goes by, but given how frequently they fell offline, it's looking promising.

My "Unit 1" which was the only one of the three that had never dropped out before - I noticed it had gone red yesterday. The other two remained green, and as usual no other devices on my wifi network had any problems (or if they did experience any problems, they rectified themselves without requiring any user intervention).
Agreeing with @bschatzow , it now looks like time for me to switch to another make of smart plugs :-(

@Bubbles Yes. This does not fix the issue. Not seeing this with my sonoff devices since I switched. Still have a couple of tplink devices and one went off this morning. Had to unplug to get it back.

@MarkNI what router do you have. I have been communicating directly with tplink support and they are blaming my Asus router.
