    New and improved replacement

    My old Arris went out after a lightning strike near my home. The Netgear modem has been reliable so far and allows me to upgrade my service to the one gig internet speed

    Netgear Nighthawk CM 2500

    I upped my internet speed and the modem I had was not capable of handling the faster speed. I was offered 4 different modems to choose from and chose the Netgear NightHawk CM 2500. Glad I did, no buffering.

    ⭐Great for Working From Home

    I've been using this modem for my work-from-home setup, and it's been great. Setup was quick and easy, and I was online within minutes. I also liked being able to grab it in-store instead of waiting for shipping. I use it 8+ hours a day for meetings, uploads, and streaming, and the speeds stay consistent. If you have a high-speed internet plan, this modem can definitely keep up. Highly recommend! ⭐⭐⭐⭐⭐

    Fantastic

    Regret not purchasing my own modem long ago instead of renting from the cable company

    good update

    Our old modem stopped being supported by Spectrum and would eventually start to drop the signal. I picked this model up as it's supported, and the signal has been perfect.
