CR1000A drops connection to internet

[JamesBXV1]

Five days ago Verizon installed a new CR1000A router in our apt building's basement with new CAT6 cable to Verizon's distribution box. It worked for a day and since I can't connect to the internet. The front LED is white. The WAN LED for the CAT6 flashes yellow and eventually stops. I tried to reboot several times, both soft and hard. Nothing works. Our iPhones connect to the router and I can open mynetworksettings.com. Everything seems to be 'connected' and nothing seems off. No one else in the building has trouble connecting to Verizon as far as I know. Any ideas?

Do you really lost Internet connection when the port LED goes off?

Notice the LED may turn off after 15 minutes by default when there is no change in connectivity.

[JamesBXV1]

Great! It's good to know that's working, too. I can't find anything wrong from the router's diagnostics or LEDs. I must be missing something.

It's not the router but the ONT that is the problem. I moved the CR1000A to another ONT and it works fine. The ONT is a Verizon I-211M-K. Is there a way to reboot the ONT?

Users can unplug the power supply for, say one minute and then plug it back in again. 🤔

[JamesBXV1]

I don't think that would have worked as the ONT has a battery which can power it for hours. I tried that and the power LED stayed lit on the ONT. I did find out how to reboot this old model. Hold down the "silence alarm" button long enough, the power will be cut off to the ONT from the battery and it will reboot. 

Now we connected again to the internet! Hurray! Thanks for the comments, it was in the right direction and I finally narrowed it down. I still wonder if it will be stable. We'll see.

Hmm....

The Alcatel-Lucent (Nokia) 211 doesn't come with a BBU. There is an optional Power Reserve unit that requires 12 "D" cells to support telephone functionality.

The 211 may be plugged into a UPS which would keep the whole unit alive during a power failure.

Could a picture of the ONT and one of the power backup unit/UPS be posted? 🤔

Does this help?

I had to reboot again this morning.

While I was at it I did a speed test: download 332 Mbps, upload 1.6 (yes a paltry 1.6) Mbps.

I don't have much hope the ONT will continue to function.

[dexman]

I would suggest reaching out to Verizon for more testing and to have them check the ONT's error log(s).

[JamesBXV1]

Yes, that's a good idea. We already have and we're waiting. If I understand correctly, Verizon is responsible for the ONT. 

Some background: this is a coop and the ONT/router is the coop's. Its main purpose is to transmit the instrumentation readings from the heating system. The system runs automatically; but we can't monitor or change settings without this control system. The super uses the wifi as an additional benefit. Each of us has our own ONT/router in our apartments for our personal usage. Most of us use Verizon.

Thus, being able to reboot the building's system gets us through until Verizon has a final fix. 

Thanks, again.

[dexman]

Let us know what the final answer is. I noticed that the photo hasn't appeared yet. 😐 

[dexman]

I just spotted the picture. interesting that the Alcatel-Lucent (Nokia) 211 is mounted inside of what appears to be an old Motorola enclosure. The 211 here at our house is mounted inside of an old Tellabs 611 enclosure. 🙂

[JamesBXV1]

It predates me by years. We don't have BB for our ONT in our apartments. I don't think a BB is needed for the building's ONT. If power goes out, so does the router. The ONT reboots faster than the router. I'll ask the Verizon guy/gal when they come. We'll see what their solution is. I'll report back. Have a good Thanksgiving all!

Verizon tells our manager that the account was "restricted" because it was a source of viruses. The 3 people with the password would not knowingly pass viruses. Verizon said it would lift the restrictions.

Over the last 24 hours I haven't had to reboot the ONT, which I usually did 3-4 times per day. Perhaps they did something. Time will tell. In any case, upload speed is a paltry 1.7Mbps (while the download is greater than 300Mbps). I suspect there is still something wrong or they haven't lifted the restrictions. 1.7Mbps?

Ah, is this one of those setups where the connection is being used to provide Internet to other Tenants? Or is this just a Staff Only setup?

I would recommend something more robust than a CR1000A if you're going to be providing Internet to tenants. Look at something like a Ubiquti Dream Machine Pro SE and an Access Point or two. The Dream Machine has the ability to block torrents, so you can keep DMCA notices away which will also put your connection into a restricted mode, and it will also support IPS/IDS which will help curb malware and other malicious traffic.

For the time being, change your DNS to Quad9's servers of 9.9.9.11 and 149.112.112.11. These provide some DNS level security filtering. Not much but it's more than what Verizon's DNS will provide.
