Mind you people, I don't often defend suddenlink, but there are other components on your networks constantly sucking down the bandwidth.
Depending on who in the house is doing what, and how much bandwidth you pay for, your internet may have issues. Your iPhones and laptops and desktops update on their own and it will slow down the network if you are also watching Netflix or trying to download that latest Jonas Bros. album.
We have Suddenlink at the office. It goes down often. That being said, I cannot log onto the router's page until I reboot it when that happens, which means it is the router and not suddenlink that is depriving me of my internet. Beyond that, the modems are teh suck.
The internet connection coming up to our businesses and homes likely is more constant than we give Suddenlink credit for, but the hardware to get it to us is usually a little cheap. That's how you keep costs down.
