RBK50 how do I change my IP Address
My IP address on my router is 10.0.0.1 and I need to change it to a 198.168.0.1 IP address. How can I do this?
Thanks,
Tony

That is a modem/router. Look at all those LAN ports on the back.
If your statement is based solely on how the device looks, then you should double check that. I read a review of the MB8600 earlier today and the review stated the device was a modem only, and that the multiple LAN ports were there only for future support of bonded connections > 1 GBps.

It wasn't just the LAN ports. I try to pin down these things by checking manuals. Sadly, this doesn't always work. Google can lead you astray. Yesterday, I had some difficulty trying to work out what a Huawei box was all about.
I did link to the manual I found. If they have instructions for "routering" it suggests that they think it necessary and it makes sense to follow them.
Did you look at that?
But a different search for the same thing found something with a single LAN port.

I dug a bit more and am now confident the multiple LAN ports are for bonded connections. The Quick Reference Guide is below, describes removing the yellow tape in the unlikely event you are using a bonded connection, and reads, "This product does not include a router...."
The OP should simply adjust his LAN IP range as I described in my first post.

There is no harm in checking that they followed the "use it with a router" advice.
"This product does not include a router...."
Strange. I searched the manual for "router". It found nothing.
Aha. The manual is not "PDF searchable"! Very helpful. It works when you process the PDF.
What would have caused the RBK50 to opt for 10.0.0.1?
Maybe the start-up regime confused the router. The manual tells you how to get that right.

Not sure about this modem, but some cable modems have a built-in DHCP server that serves out 192.168.x.x addresses until the ISP connection is established. It's there so the cable technician can log into the modem for initial setup. This has caused issues for some Orbi users who use 192.168 LANs, used hard coded IPs, and have an intermittent cable connection. Their Orbi will switch to 10.0.0.X and nothing works.
