Status.

I now have only 3 of the HS105 plugged in. One was for the Christmas tree which has been taken down. Of those 3 which are plugged in, the one in our bedroom goes offline at least once or twice a day and stays offline. It's also the one which is the farthest away from the router and behind a cabinet. The other 2 units are operating fine for the past week or so.

One time yesterday I happened to look at the bedroom unit and noticed its LED was flashing blue. I think that means it had lost its connection and was trying to reconnect. I tried to control it while it was flashing blue but it was unreachable. I looked at it again a couple minutes later and the LED was red and it was offline. I decided to leave it for a while to see if it would reconnect. When I came back an hour later it was still offline and still red. So it looks to me like it does actually try to reconnect sometimes but then eventually it seems to give up and not try again. I unplugged it and plugged it in again and it connected again. But a few hours later it was again offline.

I have the router log from this period of time which I can send you, Carl, once you send me your email address.

I have four HS105's and two HS100's, and all of them do the same thing - disconnect constantly. I have a TP-Link Google Hub and when I reserve an IP for each plug they'll last about a week before disconnecting. All plugs have signal strength between -40 and -48. Plugs are all over the house on three different floors - all disconnect randomly and do not reconnect.

I just submitted an email to TP Link support because my wife has had it with our "smart" home where she has to unplug lamps every day. It's insane. Either TP Link needs to fix these plugs, send me six new HS107's, or refund me for these plugs I already purchased. A smart plug that disconnects regularly is like a car that never starts - it's garbage.

Hello Carl. As I mentioned I am also in email contact with your customer support folks. They have sent me a beta version of a firmware update (1.5.3). I have applied to all of my HS105 units. I applied the update only 2 days ago but so far things look good. I those two days I have not seen any of the plugs go offline and stay offline. I'm cautiously optimistic. I would need to see no problems for a full week before I feel confident enough to say that it's fixed.

Well, it's been a little over 7 days and none of the devices have entered the 'unable to reconnect' state. So I am comfortable saying that the 1.5.3 firmware beta I'm using seems to have fixed the problem I was having. I should also state that I haven't seen any new problems with the beta firmware.

I believe the devices do still lose network connectivity from time to time (based on some behaviour I observed) but they now seem to always reconnect. It would be interesting to view the router log to see how often they're losing connectivity. I may check that at some point.

Your experience is a near perfect match to my symptons and repair. A reboot of the router brings them all back. For clarity my wireless devices include HS105, DLINK W110, two arlo base stations hardwired but transmit to cameras on very strong 2.4 ghz. PCs and smart phones unaffected. Exceptions to the problem are my 3 IP cameras. Two are from Ebitcam 1080s and one Geeni (Merkury) pus one  IP smart plug also from Merkury. All the problems invovle 2.4 ghz devices that get status from the vendors servers. All recover from a reboot. No 5 ghz problem. By the way I have tried a Linksys router, an Knighthawk ac2300 (new) and a new ZTE 298 from the ISP. All failed. Looking for a solution. Thx Steve
