Why aren't you making modems with fans in them?

Your modems, and pretty much every other modem on the planet are designed with no fans. As a result when you get above a very moderate speed of 20MB per second your modems start to overheat and then crash once they reach around 100 degrees. Extremely preventable problems if you would just install a fan, but for some odd reason no manufacturer does. And as a result every single modem from every company has this issue. Just install a fan, and it will fix it.

Workaround: Accessing the Cable Modem Status PageF.A.Q.

In most cases, the modem’s Status page can be accessed by browsing to the modem’s address 192.168.100.1 from a client connected to the Wi-Fi router or connected to the cable modem. If you’re unable to get to the modem’s login screen, the workaround is to manually assign IP addresses in the device (Wi-Fi router or PC) that is directly connected to the modem.  NOTE: The workaround requires knowledge of assigning IP addresses to the PC or Wi-Fi router.  Refer to the user manual for instructions. Wi-Fi Client OnlyIf you only have a Wi-Fi client, the only workaround is to change the Wi-Fi router’s WAN IP address.      Log in to your Wi-Fi router’s settings page and navigate to the WAN or Internet settings.  Set the WAN IP address to Static and enter the following network addresses. IP Address: 192.168.100.200 Subnet: 255.255.255.0 Default Gateway or Router: 192.168.100.1 DNS addresses are not needed to access the modem’s status page Save the WAN settings. Browse to 192.168.100.1 with th

Device Activation

I have my device all set up and I double checked with my service provider that the Internet would connect to the modem. As far as my service provider goes, I have an access to the Internet from their end. They said the Internet is activated and everything should be fine. However, I still can’t connect to the Internet and my lights on the modem are flashing blue. I set up the device using the mobile app and everything should be working yet. It is not. I tried calling customer service, but they’re only available during the weekday. At the bottom of the instructions for installation, it says that I need to use an ethernet cable and connect it to a computer. My computer does not have that capabilities nor do I have a gaming system that would allow me to do that. How do I get my Internet to work after I’ve paid for this $50 device?

Iam looking for a modem or a workaround to disable internet access through a CAT cable. Any suggestions?

Hi Everyone,I have a couple of years-old Netgear router and a modem supplied by Comcast. I also have a teenage son who just can’t seem to learn when enough online gaming is enough. He connects directly to the modem via a CAT cable to avoid Wi-Fi lag, which means the options in the Netgear app for shutting off access don't apply since they only control the router.Aside from physically unplugging the modem, I’m looking for a way to remotely disable his access via the CAT cable, or I’m open to getting a new modem that allows for this. Ideally, I’d like a solution that lets me control it from the comfort of my bed. It’s been a long battle, and I’m tired of trying to instill personal responsibility—I'm looking for a switch solution. Any suggestions, especially regarding managing IP addresses and router settings?

Login credential not valid for the web portal to add devices

I just bought a weather station and want to connect it to house wifi.  I figure the way to do that is on the Arris control panel.  Tried using ‘admin’ and the Preshared Key, but I can’t log in. It is an older unit (2014-2015), from WOW!. SN: 9B72G168K500682
