Question Problem replacing identical router with identical settings

[h0wieb]

Hello

I'm the "network administrator" for our home. I set up a Netgear R6230 router with 3 access points around the house and it's been running smoothly for years. I bought a second R6230 as a backup and, to the best of my limited knowledge/abilities, configured it identically to the original. But when I switch them out, there is no data throughput with the second router, either on wifi or ethernet. I tried forgetting the network in wifi settings (Mac OS 14.6.1) and logging back in. I'm connecting with the wifi network, but, again, no data coming through from the internet. Only thing I can think of is the second router is defective. Is there something I'm missing? Probably. If so, please let me know.

Thanks as always,

Howie B

Did you verify that all of the access points are still connecting properly?

If you connect (wired) directly to the router, is it working?

Likely you have to get it authorized by your ISP.

I can connect with all the access points, but no throughput. Ethernet connection from the router to my Macbook -- also no throughput.

I don't recall having to get ISP authorization when I set up the original. Anyway, I have Optimum (Altice). I know, I know . . . probably time to switch to Fios. But in the meantime, do I just call them and try to get through to tech support?

Thanks again!

What are you using for DNS on the router? Your ISP's? Or something like Google's (8.8.8.8 and 8.8.4.4)?

 

[h0wieb]

Yes, DNS is via ISP.

First router has taken IP address provided by ISP.
If your ISP provides you with only a single IP address, then
it has to be released before you can use a different router.

Either release iP address taken by current router or
disconnect current router, wait until lease expires and then
connect new router.
8h wait time should be enough. But this depends on ISP (could be more).

Brilliant! In case of emergency, how does one release the router IP address?

It can entail a call to your ISP to give new MAC address, or changing on an app on your phone. Just depends on who you use.

Got it. Thanks again and have a great day.

Probably in router management web page.

Another option is getting mac address from existing router
and assigning it to new router in router settings.

Then old router IP address doesn't have to be released.

It generaly entails powering down the modem. Connecting the new router. Then powering up the modem and waiting until it has stabilised. Then powering up the router and all attached equipment. It's important to follow this sequence closely or failure will result.
