Hi everybody,

 

I just installed a new router, Asus RT-N66U, and not I could no longer access my ISY from my PC. Can anybody help me troubleshoot. Does anybody know what needs to be done to fix this issue. Its driving me crazy

 

Thanks

Hi Seb50,

 

I am so very sorry to hear. It seems that your new router is not on the same network as the static IP address configured on your ISY.

 

IF AND ONLY IF you have a good backup, factory reset your ISY (http://wiki.universal-devices.com/index ... ur_ISY-99i), restore your backup, and once prompted about the network configuration, please choose DHCP.

 

With kind regards,

Michel

I changed my router and now I could no longer open the ISY. Could it be the IP address is not recognize by my new router. It looks like my new router use IP address 192.168.1.XXX and my old one was 192.168.0.XXX. Could this be the reason of my issue? Is their a way ti solve this without performing factory reset.

You should be able to configure the new routers base ip address to what you had before. Was the ISY configured to use dhcp or a hard address?

DHCP but I have no way to connect to it. What can I do?

If ISY is DHCP, power cycle it (so it's forced to renew, and get a new IP from your new router) and look at the DHCP logs on your router to see the IP that was assigned.

sorry my error, its a hard address

In that case, simply add a hard address in your old IP range to your PC, access the ISY and change it to work for your new subnet range, finally removing the had address on your PC.

I'm sorry not sure what this means. I'm new at all this and knowledge is limited. I was able to do it for my ELK M1 but I'm nit sure what you are referring to. Hope you can break it down for me please

I'll try. I don't know specifics on your addressing (other than what was posted above) - or the specific operating system in use (assuming windows - but exact procedure and terminology varies with edition). I'll try to keep it generic...

 

Your PC is probably getting an IP address from your new DHCP service (running on your new router) that is giving it an IP address that cannot connect to your ISY (which has a static address on your old network).

 

You need to (temporarily) change your PC away from DHCP and, instead, assign it a static IP address in the range of your old network. So, let's say your old router was 192.168.0.1 and you set ISY to 192.168.0.2 - you should (temporarily) change your PC from 'Automatic' to use something like 192.168.0.3 (just make sure it does not conflict). For the 'Subnet Mask' put '255.255.255.0'. Do not worry about the 'Default Gateway' or 'DNS servers' for the temporary step. Your PC will lose access to the Internet during this temporary step.

 

Now - connect to the ISY with your browser on it's IP address and change it's IP from (in my example) 192.168.0.2 to 192.168.1.2 - and the 'Default Gateway' to '192.168.1.1' from '192.168.0.1'. You will likely need to change the DNS address as well. When you save, ISY will reboot and you wont be able to access it again.

 

Please ensure you map the made-up addresses I gave here to your actual situation!

 

Then - simply change your PC back to 'Obtain address automatically' again - and you should be up and running again on the new subnet.

In that case, simply add a hard address in your old IP range to your PC, access the ISY and change it to work for your new subnet range, finally removing the had address on your PC.

you mention I will lose internet connection. So how will I connect with my ISY?

You'll have an IP hat can talk to the ISY, but not your (new) router.

If you still have it available, the easiest thing to do would be to put your old router back into the system and fire up your network. When you again have access to ISY, change the network setting to automatic (DHCP). When your new router is subsequently installed, you will be able to access ISY and edit its IP address back to a static one recognized by the new router.
