Motorola Storm

[Arridano Tillo]

Encompassing 26 square miles with an average rainfall of 45 inches, Weston, Florida is subject to extreme weather that can deluge the city with large amounts of water in a short period of time. Weston uses an extensive stormwater management system to allow visitors to keep enjoying an outdoor-focused lifestyle.

While out yesterday a storm hit with lightening and on my return my internet was down. On checking my CM500 Modem all lights were flashing rapidly off and on. I unplugged my modem for 30 seconds and plugged back in, but no change. I tried another outlet, no change. BTW there are other things plugged into the surge protector outlet where the modem was plugged into and all of those things are operating. I then called Comcast who could not reach my Modem. I then tried to reset the modem to no avail. Comcast is sending a technician over later this week. My question, is there any reason that all lights would flash or that the power light would not turn steady green unless there was an issue with the modem itself? Don't want to pay Comcast $70 to tell me I have a bad modem.

Unhook your coax cable from the modem. with it powered on, hold the reset button until the lights change. Might be up to 30 seconds. If you can't get the lights to change and they just stay flashing, probably a bad modem. the others devices might be fine but there might have been a surge in the coax line that caused it and why it only effected that device.

Comcast came by and had to redo some of their lines and also dropped me a new cable to my modem, so they will not charge me for a service call. As suspected the modem was fried and have ordered a new one on Amazon as suggested. I think safe to say when everything is flashing including the power light you have a bad modem. Thanks for the help.

When a hurricane hits, communications is your lifeline. In 2017, Hurricane Irma hit South Florida with winds over 110 miles per hour, causing widespread devastation. 2018 brought Hurricane Michael, a category 4 storm sweeping through the Florida Panhandle with winds as high as 155 miles per hour.

In emergency situations, every second counts. Motorola two-way radios provide instant communications with the simple push of a button. Unlike cell phones, there is no need for swiping, scrolling, or searching for apps to place a call during moments where response time is critical.

In the aftermath of a storm, you need the ability to communicate with your entire work crew at once while also making sure everyone is on the same page. Vital information can get lost or misconstrued using traditional communication methods like phone call or texts, that only reach one person at a time. Two-way radios offer group-wide talk groups so you can relay important information to an entire work crew all at once ensuring that everyone is equipped with the same information and focused on the task at hand for a safe, efficient, and coordinated response.

Powerful storms bring howling winds and pouring rain, often making it hard to hear using commercial grade cell phones. MOTOTRBO digital two-way radios have built-in noise cancellation features that minimize background noise for clear audio in harsh user environments. Certain models are equipped with Intelligent Audio, which monitors background noise levels and automatically adjusts the speaker volume up or down helping you communicate effectively and allowing listeners to hear more clearly in loud environments.

If your crew is working during a dangerous storm, you need the assurance that their radio equipment is going to last for as long as you need to stay in communication with them. Even during power outages. Whether responding to an emergency, coordinating a mobile workforce, or communicating critical information, communications is key to your operation. Motorola builds superior batteries to ensure optimal performance with a complete line of Motorola Original and IMPRES two-way radio batteries designed for high performance in demanding work environments and extended work shifts.

Unlike consumer-grade cell phones which can break easily when dropped, two-way radios are specifically designed and engineered to withstand the most rugged working conditions. They can withstand being dropped on concrete, excessive dust and rain, and even high heat and freezing cold temperatures.

Thanks for all your help and recommendations, I really appreciate it. The next question is what to look for when you run a sniffer like tcpdump. How do you know something is wrong, most of the information we get from tcpdump and wireshark is overwhelming and searching through all that information can be daunting.

Are there any filters on tcpdump and/or wireshark that can detect broadcast storms? What are the common problems that can affect a network running motorola devices on a flat network.

Recently, we had a weird issue that took out all of our CMMs, they all froze and only a manual reboot could bring them up again. We had no clue where to look because immediately we had this problem, the entire network went down. We run a NDS called OSSIM and found out that there was alot of MAC addresses changes from certain clients, could this lead to anything?

wifiguy,

Thanks for your reply. You see, that is the problem - what to look for, we have tonnes for rules on our NDS (Network Detection System) that will flag if there is a virus or malicious attack. However, if the problem originates from a remote site, the entire network can go down without the problem reaching our NDS because we run a flat network.

I know the ultimate solution is to put in routers at key sites but this is a long term solution and we have over 20 sites at the moment. I was wondering if there is a way we can spot this issue whilst it is happening.

Thanks once again.

As far as monitoring my network, one thing im trying to do is set up a box that only captured igmp reports, does anyone know how to configure wireshark for that? I want to leave this running all day so if there ever is a spike i can find the source asap.


Thanks

No outage in my area at the time of the post or now. The modem stopped working when a thunderstorm passed over my area 2 days before and caused an outage in the area that night which Comcast said was already resolved.

The teams also have over 40 quick-deploy network assets that can restore connectivity where needed. This includes heavy-duty SatCOWs (Satellite Cell on Wheels) and SatCOLTs (Satellite Cell on Light Trucks), VSATs (Very Small Aperture Terminals) and microwave technologies.

While many of our stores in the area have re-opened, there are some that are still closed or on reduced hours. Please use our store locations for T-Mobile and Metro by T-Mobile to check your nearest store, as some locations may be temporarily closed or operating under modified hours in the coming days.

Commercial power outages and storm-related damage are creating service interruptions for some customers, T-Mobile President of Technology Ulf Ewaldsson shared on Monday evening. Ahead of the hurricane, our emergency restoration teams staged a fleet of heavy-duty network and disaster relief vehicles, as well as temporary connectivity solutions and portable generators, in multiple locations. Where our teams are able to safely assess network sites, they can quickly deploy these critical assets to restore connectivity.
