Review on 📶 Renewed ARRIS SURFboard SBG7600AC2 DOCSIS 3.0 Cable Modem & AC2350 Dual-Band Wi-Fi Router: Cox, Spectrum, Xfinity & Other Approved ISP Support (Black) by Oscar Colangelo

I just ran it and it seems to be working as advertised. But here's a big mistake in selling a used router. It has the SSID (WLAN name) and password of the previous user. You can detect the SSID if it shows up after turning on the device, but there's no way to find out the password. Thanks to someone's review, I realized that you can factory reset it so that the side of the device is usable. You need to press and hold the button in the small hole on the back above. The SSID and password are then reset to the factory settings. I feel the product should come with a piece of paper (instructions) explaining this or Revain should just do a factory reset before shipping to avoid confusion. I first contacted tech support (Revain) who couldn't tell me to do a factory reset. They only offered to refund my money or send me a new one. So I got a new one after being told I wouldn't have the same problem again except me. So five days passed because of an oversight.
