Wi-Fi & connectivity

[cjheritage]

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. 😞

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.
