LB120 DHCP is out of control...

Model: LB120  
Hardware Version: V1
Firmware Version: 1.8.11

What is up with this LB120? It's having major problems with DCHP. I've reserved the address in my router for it and all TP-Link devices in my network. But it keeps asking for an IP. For example -

 

[DHCP IP: (192.168.0.72)] to MAC address 50:C7:XX:XX:XX:XX, Saturday, Jan 02,2021 20:07:48
[DHCP IP: (192.168.0.72)] to MAC address 50:C7:XX:XX:XX:XX, Saturday, Jan 02,2021 20:06:40
[DHCP IP: (192.168.0.72)] to MAC address 50:C7:XX:XX:XX:XX, Saturday, Jan 02,2021 20:04:38
[DHCP IP: (192.168.0.72)] to MAC address 50:C7:XX:XX:XX:XX, Saturday, Jan 02,2021 20:04:01
[DHCP IP: (192.168.0.72)] to MAC address 50:C7:XX:XX:XX:XX, Saturday, Jan 02,2021 20:01:47
[DHCP IP: (192.168.0.72)] to MAC address 50:C7:XX:XX:XX:XX, Saturday, Jan 02,2021 20:01:28
[DHCP IP: (192.168.0.72)] to MAC address 50:C7:XX:XX:XX:XX, Saturday, Jan 02,2021 20:01:11
[DHCP IP: (192.168.0.72)] to MAC address 50:C7:XX:XX:XX:XX, Saturday, Jan 02,2021 20:00:42
[DHCP IP: (192.168.0.72)] to MAC address 50:C7:XX:XX:XX:XX, Saturday, Jan 02,2021 19:55:01
[DHCP IP: (192.168.0.72)] to MAC address 50:C7:XX:XX:XX:XX, Saturday, Jan 02,2021 19:53:28

 

And that's just a small sample, it does this all day long and variois times of day. The other bulbs do it also but not nearly as much. I updated the firmware on just that one bulb and it still hammers DHCP. I think another LB120 was doing the same over a year ago until it finally died.

Is there a fix for this?

 

thanks!

@jxmot 

 

Might be indicating network disconnects if they are frequently compared to the others.

 

You could do a constant ping request to see if you get timeouts that coincide with the DHCP requests.

@Tony 

 

 

Thanks, but you need to be a bit more specific.

 

If you mean pinging my external IP that's not going to happen. I have it disabled on my router. The router is working very well, and no other devices are having issues. Just that bulb.

 

Here's a table of DHCP requests that are questionable:

 

Qty         mac                                  IP
139 - 50:C7:BF:bb:aa:dd  - 192.168.0.72 <-- bad LB120

  10 - 0C:80:63:??:??:01 -    192.168.0.170 <-- almost bad HS220, but this device is the furthest away from router.

   6 - 50:C7:BF:??:??:02 -      192.168.0.74 <-- LB120 physically next to BAD LB120

 

An example of what I expect to see, as an exmple:

 

Qty         mac                                  IP
   2 - D8:0D:17:go:od:09 - 192.168.0.210 <-- HS105 physically near the bad bulb

 

The "Qty" is the number of DHCP requests in a 24hr period. The MAC addresses have been modified, and they're easier to see in the log below. There are 9 other TP-Link devices on my network and they're working just fine. Except for the HS220 because of its distance from the router. I'm not surpised by its inability to stay connected. The HS105 mentioned above is the same distance away from the router as the bad LB120. Maybe even a little further. And the 9 other devices sending a DHCP request only twice in a 24hour period.

The bad LB120 also was rejected for WLAN access, that occurs once in the following log.

 

Look at the following, this is yesterdays log(non-tpllink devices have been removed, they behave as expected):

The ping test meaning using a computer on the same LAN as the bulb and constantly pinging that: ex. ping <ipaddress> -t on a windows machine.

 

We do have a manual firmware updater that you can try to see if uploading the firmware again would help: https://static.tp-link.com/2020/202003/20200312/Upgrade_Instruction.zip

I did try a ping test like you've suggested. I pinged the bulb in question and a physical neighboring bulb. The bad bulb would show the DHCP issue at the same time as a ping failure in most cases. The other bulb did not fail any pings. I ran the test for about an hour. Here's a handy ping tool for windows that lets' you ping more than one host - https://www.nirsoft.net/utils/multiple_ping_tool.html In regards to the manual updater, the bad bulb was recently updated. Will the updater overwrite the last update? If it does that's a good thing. Thanks!

It is supposed to reflash the firmware so if something was wrong with the software it should correct it, but if the issue keeps happening then I'd reach out to support since no other bulbs act the same way.
