Roku rejects IP offered by DHCP

Jump to solution

I recently retired my AirPort Extreme wifi router and replaced it with a Linksys AX6000.

The old wifi network was named 'Apple Wireless' and used IP range 10.0.1.x.

I named the new network 'Wireless' and it uses IP range 192.168.1.x.

All my devices reconnected to the new network without a problem, except my Roku 2 and Roku 4 boxes.

I get the green check for Wireless connection, but a red X for Internet connection with error 009.

After hours of Google searching and troubleshooting not getting me anywhere, I turned on logging on the new Linksys router and this is what I see:

DHCP client log
LAN IP address | MAC address | Timestamp            | Message type
10.0.1.26        08:xx:3A      2021-05-26T11:06:21Z   Nak
10.0.1.26        08:xx:3A      2021-05-26T11:06:21Z   Request
192.168.1.199    08:xx:3A      2021-05-26T11:06:21Z   Offer
undefined        08:xx:3A      2021-05-26T11:06:21Z   Discover 

 

What this looks like is -

  • Roku introduces itself to the router
  • the router offers Roku an IP address of 192.168.1.199
  • Roku says, 'No, I'd rather use 10.0.1.26, which is the IP address I've been using for the past 5 years'
  • the router rejects that request, since that IP address isn't within the correct range

I've tried reset network settings, I've tried factory reset, but nothing I do will make those Roku boxes give up the IP addresses they used to use on the old network.

Anybody have any suggestions?

I thought about just changing the IP range of my new network, but apparently Linksys hardcodes to 192.168.x.x. Smiley Sad

Any help would be greatly appreciated.

Well, as Murphy's law would dictate, I almost immediately discovered the solution after posting.

I still have my AirPort Extreme connected via the wire to my new router so I can continue to use it as a NAS for Time Capsule.

I disabled its wireless, and I thought I changed the Router Mode to Off, but I had left it on DHCP and NAT. So, I had 2 DHCP servers running on my network.

Ddddduuuuuuhhhhhhh.

Roku is connected and happy.

Thank you for posting your solution, even if it was a 'stoopid' mistake.

Ditto.  Will no doubt be useful to others experiencing a similar problem as possible issue to check.  Many people forget to unplug their old router after installing a new one.
