last week I had to do a factory reset on my router, since then the hub will not connect. Iāve done the restart, tried every Ethernet cable in my house, tried every port on my router, tried additional routers in between, hooked up directly to the modem, opened up the 6 ports suggest, and then put the router in a DMZ, made sure the reset button wasnāt getting pressed in from the case not aligning. Iāve even hooked up the power adapter to my multimeter to check the adapter (itās fine).
Just now I tried adding the hubs mac address (which I got from the ide page) to apply a static route to it. After restarting the router it connected and gave a solid blue light for over 30 min. then went INACTIVE in the IDE. The whole time it showed inactive on the phone app. I decided to cycle the hub and now I 'm back to blue blinking lights and it wonāt connect to the router again.
So as I write this, literally at this point in my typing, I tried one more thing out of desperation. Iāve turned off any 5gz signals on my wireless (not sure why, just reaching at this point). and the hub just came on green and appears to be āon lineā in every way. Was this a coincidence or did disabling my 5ghz wireless actually do something?
Iām more concerned for if this happens again. I want to play with it to test some theories, but I donāt want to go dark again. Iāve become to accustomed to my smart home to go back
EDIT: as I post this it just disconnected again, lights on the front are solid blue. Nothing makes sense anymore.
EDIT 2: The hub is up and running over 24hrs now. Iām guessing I had a fringe case scenario, but as Iāve read itās a good idea to assign an IP to the Hub anyway.
Captains Log: unplugged the cable from the router, plugged it back in to the same port. turned green instantly. I checked the calendar, itās not Friday the 13th, so I feel like Iām being trolled. How long will my connection status last? Hard to tell. Please pray for me.
Thanks, I didnāt actually call support yet, that was my next stop. I know itās the wrong attitude, but by the time I get done going through all the motions with support Iām left with āsend it back and weāll take a look at it.ā Being a fairly technical person I wanted to figure this one out, and not cop out to āa bugā.
The hub came back on line, and has been solid now for 30 min. Iām going to put logging on it to check itās transactions. The only thing I can think of is the hub holds ip and routing pretty hard and doesnāt try to re-adjust when network conditions change. When I added a static DHCP to it it might have connected, and then spent the time downloading new firmware, possibly longer then the ST noted time of āup to 30 minā.
Iām going to keep a steady eye on it, Iād really like to know what I did wrong in the first place to avoid this. Possibly help out someone else.
Which router do you have? I had a router (and I canāt remember who manufactured it but it wasnāt cheap) that would cause similar problems with my Harmony hub. Iād reboot my router and it would be fine for a bit. Replaced the router and everything was fine.
I have a Linksys EA9500, yeah, not cheap. I found out a while back that one of my twisted strands from my modem to the router was busted. I attributed all my network issues to that, and had relatively no issues since, but am still waiting to see.
I think itās very bizarre that the ST hub wouldnāt connect to itās IP until I reserved it. The ip listed in the IDE was open and available on my router. Not sure which one to blame for this, but 20 hours and still going strong so far.
I Think I may have had the same one. The darn thing eventually kept rebooting on me at random times. I ended up going with an airport extreme and everything has been fine.
If I dont reserve the IP the hub flahes blue as in it cant get a valid IP. On the router I donāt see the hub try to connect, or any indication that it ever was connected.
Man, that is not what i want to hear. I was having problems about every three months were wired devices wouldnt be connected by wifi devices would be fine.
I found some wires in the ethernet from the modem where broke, and was hoping all the weirdness was attributes to that. It has only been a month so i cant say for sure yet.
Next troubleshooting step would be to only connect the hub with a cable you know itās good.
Also, go into the router, LAN/DHCP reservations and see if threās anything there. If there is, delete them and restart router.
Let me know the result.
BTW, thereās no relation between 5gHz and wired connection. It seem that somehow there is a conflicting IP address.
The broken strands in the cat5 where leading up to my issues with the router. Once I remade the ends That cleared up all problems with the router and all other devices on the network. While Iām sure it contributed I didnāt root cause that to issues with the SmartThings hub.
I believe the 5ghz bands was just a coincidence, there shouldnāt be any relation between my wifi bands and the wired ports, exceptā¦ there is when the router has issues. Makes no sense but Iāve had times in the past where wifi works fine while all wired connections are disconnected. It could also contribute to a compounding issue/bug within the routerās OS. There where no other DHCP reservations in the router, and there was no device assigned the IP last registered to the hub as listed in the IDE.
The hub has been working over 24 hours straight now. Iām guessing after I manually assigned the IP it was working, but for whatever reason was taking longer than 30 min for updates to take effect.
