isy-994i can not connect to network

[tedolsen]

hi all, i need some help  thanks in advance for any you can offer!

i've seen discussions on this matter... flashing memory and error lights. but please bear with me while i fully explain my issue and what i'm seeing on my isy that no longer connects to my local network.

-the isy is connected to my network (cable between it and a network switch, same as when it worked)

-i connect power to the isy

-the lights act as follows

  solid power light comes on shortly followed by

  solid rx and tx

  the memory light flashes then goes out

  solid power, rx, tx still on

  memory light flashes on again then off, tx also goes off

  power and rx are still on, memory and error lights begin flashing

  isy stays in this state

while all this is happening the ethernet port left light is on solid, the right one is flashing

all that i've read on this would seem to indicate it's a network problem? no sure how because i can connect a roku to the exact same switch port using the exact same ethernet cable and it acquires an ip address from the network and works fine.

couple other things to add is that i've seen a problem similar to this in the past but it seems to have always self corrected by itself or with a power reset.... and lastly i did attempt to change the isy's ip static address prior to this problem occurring. i changed it from 192.168.1.240 to 192.168.4.240. i brought up a new 192.168.4 network and was able to access the isy. i then changed the isy to use dhcp and now i can not access it from either the 192.168.1 or 192.168.4 networks.

thanks for any thoughts you might have!!

@tedolsen Please refer to the wiki for what the lights mean:

https://wiki.universal-devices.com/index.php?title=Main_Page#Front_Panel_LEDs.2FLights

What brand router are you using?

If you have auto DHCP set on the ISY then log into the router. Does the router show the MAC/UUID connected anywhere (new IP)? It does seem that you're having network issues. 

Do you have ISY Portal activated for this device? If so, log into my.isy.io and see if it is reporting the ISY online. That should at least give you the remote access URL that you can use to get Admin Console to load (remember to log in with ISY Portal user/pass). 

It's always best to set a DHCP reservation on your router rather than static IP on the ISY. For this case for sure. If you change the router and available networks it might not be able to connect if the ISY is set to get a a static IP that's no longer being offered from the device handling DHCP routing. 

If you have a PLM make sure that it is powered on and connected before you power on the ISY. It's possible that putting the network into the PLM port and the PLM into the network port (on a ISY994).

• Error light and Memory light blinking simultaneously: ISY is not able to get on the network.Please ensure:
  • The Network jack on the back of ISY is connected to your router
  • The lights on the Network jack have one steady on and the other one blinking. If not, check cable and connectivity to the router
  • Your router provides DHCP
  • There are no other devices on the network with the same IP address (IP Conflict)
    • If you have configured your ISY to use DHCP, then you will have to search your network for devices that might be in the same DHCP range as your router is providing
    • If you have configured your ISY with a static IP address, and as long as you have a good backup, you can Factory Reset your ISY and then restore a good backup (File | Restore ISY). Once prompted to change the network settings, choose No

hi geddy and techman, thanks for your responses!

concerning the lights "Error light and Memory light blinking simultaneously:"

this is true BUT the power and rx lights are still on as well. still thinking network problem?

 

"Boot up sequence: Power, RX&TX, momentary blink of Memory/RX and TX, and then Power only"

mine never gets to power only, my final light configuration is power, rx on solid, memory and error flashing

"router" = eero on 192.168.4 network.    att bgw210 on 192.168.1 network. the isy does not show up on either router.

"Do you have ISY Portal activated for this device"    no

"It's always best to set a DHCP reservation on your router"  dhcp reservations are set up on both routers and i checked that no other devices are using the address specified for the isy

"If you have a PLM make sure that it is powered on and connected before you power on the ISY"  done and i can see the lights on the plm below the rj45 port blink when i power up the isy

"It's possible that putting the network into the PLM port and the PLM into the network port (on a ISY994)"  the ports are wired properly

techman, i've confirmed all the points within your post

any possibility it's a sd card/corrupted file system issue?? thanks again guys!

[Techman]

You can try removing power from the ISY, then remove the SD card and clean its contacts with a soft eraser. then reset the SD card.

If you're still then having the problem, it's possible that the SD card failed its rare but it does happen.

Upgrading Your SD Card In some instances, you may want to replace your SD card. For example: • You are experiencing a blinking ERR light which could indicated a bad SD card. The ISY supports up to a 16GB SD card. Once your SD card is replaced, you will need to re-load the firmware onto your ISY as well as restore your configuration from a backup. Please be sure to have a good backup before attempting an SD card upgrade. With you ISY you have an externally accessible SD card. Simply unplug all cables from your ISY, pull out the old SD card, and insert the new SD card. You will also need to reload the firmware onto your ISY. Proceed to the paragraph labeled “Reloading The ISY Firmware and Restoring From Backup.

32 GB card also works, and is easier to buy.... look specifically for the newer A1 rating, also note it's a MICRO SD card.  (A2 is also ok but will fallback to A1 as A2 requires hardware support that the ISY doesn't have.)

Why do you have 2 devices handing out IPs on your internal network? Have you always done that or are you setting up new routers? Do you mean to have two different wireless networks? They can't talk to each other since two different devices are handling the connections. Usually this is not an ideal situation. Either the AT&T gateway should handle everything or it should be put in bridge mode and let the eero device handle everything. 

Since ISY994 is hardwire only and not wireless which device are you connecting it to?

I still think this is Network related. Especially since you said you let eero handle one set of IPs and AT&T Gateway handing out a different set of IPs. Sounds like you're connected to the eero and it's not actually sending anything out to the internet. Connect the ISY to the AT&T gateway and see what happens.

 

I think @Techman and @MrBill might be onto something too about the SD card, but my thought is that it's still network related. 

I think what @Techman pasted above (from the Wiki) just doesn't clearly say the RX light would also be on. If it's always trying to make an internet connection then I think the RX would be on because it's trying to communicate. The flashing memory and error are what are indicating network issues.

I agree, I missed that there where two networks.....  192.168.4 and 192.168.1 don't pass traffic to each other without some advanced networking, they are on the surface considered separate networks.   One or the other needs to be in bridge mode.

long story on why 2 networks... i've had the two networks running for a year or so with the isy running without problems on the 192.168.1 network. i was attempting to move it to the .4 network when i ran into the problem. i was also attempting to change from a static address to a dhcp address. i actually got it up on the .4 network once then changed the isy's config to dhcp and haven't been able to get it back up since. i do have two diff wireless networks, 1 eero and one att  with different network names. the att network will go away once i get everything converted to the eero. these two wireless networks have no issues other than i can't get the isy to connect to either one of them.  one other comment on something i stated in my original post, i had seen this problem in the past when having to shut down the isy for various reasons. sometimes it wouldn't come back up without multiple power resets. that being said, it's been working perfectly the last couple of years.

going back to the sd card, i tried cleaning the contacts as techman suggested and it still doesn't work. guess the next step will be to get a new sd card and go from there??

thanks for clarifying how the lights should be behaving

just to confirm...you're using a wire to connect the ISY994 to some network device. Right? The ISY994 DOES NOT HAVE WIRELESS...you say you can't get it to connect to a wireless network...how would it? 

Have you attempted to plug the ISY994 into the AT&T gateway and it still won't connect? And you put it in DHCP status recently?

 

[tedolsen]

hey geddy, sorry about the confusion, i understand that the isy doesn't have wireless.  i can't get it to connect to a wired network... i have two wired networks, that also happen to have wireless  when i connect the isy via patch cord to either of the networks it will not acquire an ip address.

yes, i've plugged the isy into the att gateway and it won't connect. the att router/home network/ip allocation page does not show the isy.

@tedolsen thanks for clarifying. Just seemed really strange.

If you're still having issues then I'd suggest opening a support ticket with UDI. 

Submit a Ticket:         https://www.universal-devices.com/my-tickets
Email:                          support@universal-devices.com

 

It seems you've tried almost everything. I think if you're having connection issues just changing the microSD card might not really be the fix for you since you have to have it make a connection to the network for you to be able to telnet into the unit to install the firmware on the new microSD card. 

When you submit your ticket make sure you mention you have 2 different networks and it will not connect to either and be sure to have a clear explanation of the light pattern. It might even be good to take a short video of it and attach that to your ticket. 

Good luck! Please post back once you get back online what the solution is so it might help others that might have this issue.

thanks getty, will do! and thanks to techman and mrbill as well, your help is appreciated
