Do leased cable modems' routers still work during outages?

Hello.

 

When there's an Internet outage, does the leased cable modem's router's LAN still work?

 

Just wondering. Thank you for reading and hopefully answering. Smiley Happy

depends on what is causing the internet outage.....if you have no electricity it's certainly not going to work.

No difference between bought or leased modem/router for service or power outages.  If owned goes out so would the leased one.  If you had battery backup you may still get internet without electricity but if internet gone off the line would not matter.

With three possible bundled services (cable, internet, and VoIP telephone) all being connected over the cable, any "YES" answer is qualified.   If it's just the internet data flow that is interrupted, your home router and its WiFi will continue providing DHCP to your local LAN.  This applies equally to both 'rented' and customer-owned modems and routers. 

However, depending on exactly where the internet signal path is broken, there probably won't be any DNS to route messages across those remaining network segments that are still healthy, and Spectrum VoIP telephone service will NOT operate until its connection to Spectrum's regional VoIP telephone server is restored.  That's why Spectrum recommends VoIP phone users have an alternate way to call for help, such as a cell phone to dial 9-1-1.
