    lb 110 bulb loses connection

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    My LB110 bulb loses connection with the Kaza app and Amazon Alexa. I have to toggle the switch off/on before the app and Alexa can re-detect the bulb. Has anyone else had this issue? Please advise.

    Hansen you aren't alone, I've had the same problem with my LB-110 bulb. If you haven't done so, post a review and identify the issue so other potential purchasers ae aware of it. I posted reviews both on this site and Amazon where I purchased the bulb.

    The bulb seems to lose connection to the network, I run network monitoring tools on my home network and will find the bulb is not connected. I'm hoping TP-Link comes out with a firmware update to fix this issue.

    Me, too!

    I recently purchased two bulbs (LB 100 & LB110) as a trial and have the same problem with both of them. I tried linking them with a different router, and still had the problem of having them lose connections. Here's hoping there's a solution! The company's motto is "Reliably Smart". Really.

    See the post in this form/area "110 and 130 Bulbs dropping / losing connnection". It gives some areas of possible trouble shooting. General questions would be:
    How many devices on your 2.4G wifi?
    How old is your router and what is it's total bandwidth on 2.4G?
    Do you stream video or use computers for gaming? If so, can you move these to the 5GHz wifi?

    Generally, I have had few problems with my system? Zero drops. I have 12 devices on 2.4GHz and 5 on 5Ghz Total bandwidth is 3.1 Ghz.

    Could it be the lamp's fault?

    I wonder if it could be the type of lamp that I'm using. Most of the stand-alone lamps in the house are three ways. This doesn't affect the regular bulbs, but I wonder if the different settings are resulting in a lower voltage being applied, and that is causing the bulbs not to retain their settings.

    What kind of lamps are you using?

    After contacting support I was sent a link to a tool that once downloaded allowed me to upgrade the firmware on my LB-110 to V1.2.2. Since upgrading the firmware I haven't had a disconnect, where as before it had gotten to the point it would only stay connected for a couple hours at a time. Hopefully this Firmware upgrade is the solution. I left a star off since the KASA application did not identify that a newer firmware edition was available.

    Are you the Firmware was 1.2.2 ? I just got a link for the updated firmware from support and it only updated my LB110's to 1.2.1 ?

    Just want to make sure what is actually the latest version because I am still have connections drops quite frequently and its pretty frustrating dealing with this. I have 3 HS100's smart plugs that have worked flawlessly from the day I plugged them in almost 2 months ago ! I had nothing but issues with the HS105 model and had to return the for the Original HS100 model .

    Having same issues with dropped connections, odd thing is no dropped connections on my HS100 smart plugs, had a bear of a time with keeping HS105 smar plug connected, returned it for another HS100 and that works flawlessly, I am no having dropped connection on LB110's , have been provided with firmware update 1.2.1 , I read timwalshmi post where it was listed with 1.2.2 and I am wondering if anyone else has been provided access to 1.2.2 or if it was a typo on the version ? Not sure how to solve the dropped connections at this point !! any ideas ?

    I got my tool from Rachel Li from Support. I just verified in the Kasa app on my iPhone that my bulb is a LB110(US) and the Firmware Version is 1.2.2. I also checked the bin file that comes with the tool, it also lists the firmware as 1.2.2. (smartBulb_FCC_1.2.2_Build_161230_Rel.160635.bin). Looks like this version was built on 12/30/216.

    I attached a screenshot from Kasa as well as the .bin file compressed as a .zip. I'm not sure I'd trust me however and download the bin, but if you do extract it to the firmware sub-folder of were you extracted the tool you were sent

    C:<path to where the tool wasextracted>\iotUpgradeTool_V1.0(LB)\iotUpgradeTo ol_V1.0(LB)\firmware


    I did see a post on Amazon about version 1.2.1 not fixing the problem.

    It's been 3 days, and I still have not had to reset the settings in the bulb.

    As a side note I asked Rachel Li if my HS100(US) had a similar FW upgrade available, and she sent me FW version 1.1.2 which I installed on my smart plug. It looks like we may be getting "beta" releases as they try to fix the problem. It would be nice if they made them available through Kasa,

    Thank you Tim, I have just emailed their support asking them for the same file so i can apply to my HW ! Not sure why they insisted the 1.2.1 was the latest firmware when I asked for 1.2.2 based on what I had read !

    Hope all is still working correctly for you !

    Just got the 1.2.2 version from Support, updated my LB110's bulbs, fingers are crossed that this finally solves the issues I have been having !

    I noticed my bulb would flash on and off. I think I'm losing the connection when it does that. It's always reconnects so not bothering me that much. I did lose my connection to Alexa yesterday, but again it reconnected. Still watching it and definitely happier with it now.

    Disappointed in TP-Link

    I have the same bulbs and plugs. My LB120 fw version is 1.0.9. When running check for updates, the result is no updates available. TP-Link is either not pushing SW updates to production / distribution or the tool does not work. With the on-going wifi stability problems, it seems an update push is OVERDUE.

    I've been having similar problems, I have a 20 device network, my LB120/LB130 lightbulbs would occasionally not respond to Echo/Alexa commands, or drop off the network entirely (Kasa couldn't see them either), so I did the following things:
    1. I upgraded my router to an OnHub (TP-link makes one model, ASUS makes another), since they claim that can support up 100+ devices. Many less expensive routers are more limited in device support, so if you have a $20-$50 router, and are having issues, it might be worth looking into. The device I picked cost about $150 USD, but I have a lot going on over my network, so I could justify it.
    2. I also wound up turning off my local (Comcast) private network, to prevent "double NAT", and changed all my devices over to the new network/router (Which took me about half an hour, might take somebody else a few hours if they don't spend a lot of time working on networks). For the lightbulbs, turn them off and on 3 times, "add" them in Kasa, and they'll get the names they had before. For HS 100's, hold down the settings button. This combination bumped up my WIFi speeds in the process, after I did both things I went from from 97Mbs/sec to 230 Mbs/sec on my faster computer, which is nice.
    3.I also found a for the firmware upgrader, for folks looking for that. On the FAQ page for the plugs )(not the lightbulbs), http://www.tp-link.com/us/faq-949.html, there's a link to:
    http://static.tp-link.com/iotUpgradeTool_V1.0.zip
    The iotUpgradeTool does what we all kind of hope/expect the Kasa app to do... update firmware. Even though it's on the plugs FAQ page, it also does lightbulbs. It requires a windows machine of some kind to run (so, if you're a Mac or Linux house, you might need to borrow one, and put it on your network while updating firmware).
    a.) extract it and run the "main" application in the folder.
    b.) Press "scan" to get a list of devices on the same network as the machine running the tool.
    c.) Select a device and press "upgrade". It'll churn away and upgrade you devices.
    After doing so today (2/12/2017) for all the devices, the Lightbulbs (LB120,LB130) are on "1.2.3 Build 170123, Rel 100146", and the WiFi switches, HS100's, are on "1.1.2 Build 161014, Rel 12426"
