MT3000: no internet access

Routers
1

No internet access using new MT300 through either wired or wireless network. Internet access fully functional using old router.

Internet service through Xfinity (Comcast). Modem is a hitron CODA.

Connected ethernet cable from functioning modem into WAN port. Connected ethernet cable from computer to LAN port.

Logged into Admin Panel v4.2.2. In the "INTERNET" tab, Ethernet shows "Connecting..." but does not connect. Protocol is "DHCP"

Able to connect devices through WiFi, but also no internet access.

Please advise.

Are you using the same Ethernet cable between the modem & Beryl AX as the previous router? If so do you happen to know if — note I'm speculating here — if Comcast restricts what equipment can be connected to their modems?

Thanks for replying.

Yes, it is the same cable. I simply unplugged it from the old router and plugged it into the new one.

I'm not aware of any restrictions like what you mentioned. I own the modem; it's on Comcast's approved list, but I bought it from Amazon a couple years ago.

& there's no issue using said cable when directly connecting the modem to, oh, say, a laptop, correct? Regardless I'd download the latest stable build for your Beryl AX & flash that manually (GL GUI -> System -> Upgrade -> Firmware Local Upgrade). v4.8.0 is the current. Use 'common upgrade.'

I should have mentioned that earlier. Apologies.

Good idea. I'll go download the latest firmware now.

Success!

I downloaded the latest firmware from the link you provided. Installed it, but same result. Then I noticed that the upgraded Admin Panel had a button (looks like an open book) in the upper-right corner of "INTERNET" for a beginner guide, so I took a look.

I tried out the Network [Configuration] Guide and it suggested to reboot the modem. Lo and behold, that was apparently enough to connect the modem to the MT3000 Beryl AX.

Everything works now. They should add these instructions (to upgrade the firmware and to reboot the modem) to the setup card included in the box.

Thanks for your help!

Good stuff! Don't forget to mark the 'Solution' to let others know who may stumble upon a similar problem.

So done. Do you work for GL-iNet? If not, they should hire you! LOL

Nope; being on this forum is my idea of unwinding. I don't think I could do customer support again (thousand_yard_stare.png).

Have a good day.

The reason that works is that the ISP stores the MAC address of your current router. Rebooting the modem clears it and allows you to use a different router.

Thanks. That makes sense. My new troubleshooting rule of thumb. When in doubt, reboot.
