Hello, I’m new to the community and SmartThings in general. I’ve had my Hub v2 for about 3 weeks now and ever since I plugged it in, I’ve been having DHCP issues on my local LAN.
A little about my hardware:
- 10 hue bulbs with the phillips hue hub
- Harmony Hub remote
- 3 SmartThings sensors
- raspberry pi with homebridge for Siri control
- Hitron router (from my ISP)
A little about my setup:
- Sensors in the closets to turn the hue lights on when the door is opened
- Lights in the living room the turn on/off at sunset/sunrise
All-in-all a very basic setup at the moment and now the problem:
- Day 1 I received a message saying the hub is offline so I looked around and realized my wifi was out
---- Solved by rebooting the router.
- Day 3 I received this message again, my wifi was out again
---- I put a static IP/dns on my laptop and logged into my router to see what was up
---- The internet was still working, and I had a correct WAN ip and dns
---- The LAN clients were getting APIPA however (automatic private ip address) of 169.254.0.0
---- I reset dhcp, no fix, I unplugged the SmartThings hub and reloaded my router
---- Solved, everything is back up (I left the hub disconnected from my network at this point)
- Day 10 I haven’t seen any further problems now that the hub is disconnected
- Day 11 Looking through this community, people advise to:
---- Use reserved dhcp leases (this didn’t change anything)
---- Increase the dhcp lease time, this improved the situation but now the problem simply occurs less frequently (every third or fourth day instead of every day)
So… now I’m here asking the community because so far the SmartThings hub v2 appears to be messing with DHCP on my Hitron modem and causing the LAN to use APIPA which breaks wifi in my house.
What else can I say?
- I only have a laptop, no wired PCs (only wired computer would be my raspberry pi and it is affected as well, with a static IP, it works during these outages as well)
- If there are no solid answers, I may need to bring my work laptop home and do a wireshark capture although I’m not excited to sit around and wait for this to happen with wireshark running.
- Does anyone know if SmartThings is aware of this issue? Maybe a fix will come out soon?
