J179 SIP Phone Ethernet Port not talking to Network 1

[tac84]

I recently deployed a brand new J179 phone to replace a 9611G and have a laptop connected via the ethernet port on the back of the phone. The J179 is working fine, talking to the IPO via DHCP with no issues. Strangely my laptop which also has DHCP enabled has been given a completely different ip address and subnet. If I plug the laptop into the back of a J169 or any other IP phone, everything works fine. It's probably something simple but can anyone help me understand what this new J179 could be doing with its ethernet port? FYI- The ethernet port is enabled and have checked all the settings in the admin on the J179, everything looks fine but I must be missing something...

I would check your switch port configuration. Maybe you have voice and data VLANs on it. So when your phone boots up it will take an IP from voice vlan and your pc will get one from the data vlan.

Thanks for your reply. I only have a small non-managed PoE 16 port switch on my network so I don’t have any of that set up. It’s really strange that I can plug into any other IP/SIP phone and the laptop is fine but on this brand new J179 it goes rogue...
Thanks for the suggestion though. Maybe I should try a hard reset on the J179?

clear the phone and log it back in again, you might need to clear it 2 or 3 times for it to take.

Thanks Mike. That was frustrating. This is how I resolved the problem:
Cleared the phone 5-6 times however this still didn't resolve it. The laptop was still on a network of its own.
I then unplugged the main ethernet cable from the J179 and plugged this directly into the laptop. DHCP kicked in like it normally does and the laptop was on the network and working, internet browsing, etc. I then plugged the main ethernet cable back into the J179 and used the secondary cable from the J179 back to the laptop and it then decided to work. Frustrating, but at least it's now resolved. Thanks so much for your help Mike.

so it is jinxed
hopefully you don't ever have a power outage that goes then back to this issue.

I concur with teletechman - thanks for posting the solution

No problem, when you say it’s getting a completely different IP subnet, is it from the APIPA Range?

@Icet500 - No, it went completely rogue! Glad it's resolved now

Glad to hear!
Just a heads up, if your pc is set up To use dhcp, and it’s getting an IP range not from the APIPA , then there maybe another dhcp server enabled in the network.
