Great way to break away from leasing

Nice and compact. About half the size of the Xfinity supplied modem/router that I had been using. First photo shows all of the contents of the carton, and the second shows the WavLink modem on the right, and the old Xfinity modem on the left. Sloppy initial setup by me. I'm in my fifties, and not a tech expert by any means. From the time I opened the box, until I had an Xfinity television cable signal and ethernet internet, it was 15 minutes. Another 10 and I had a new WiFi router connected. I have a 200 Mbps cable plan, and my first and second speed tests both showed 236Mbps and 239Mbps download via Ethernet, and the same via WiFi. This modem does not have a built-in WiFi router. That wasn't a problem for me, I bought an AC1200 dual band (2.4ghz & 5ghz) router for 30 bucks. More than enough speed for me. I'm not a gamer, and don't have a lot of devices connected; just a Wi-Fi extender, a phone, a tablet, and a laptop. 100% of my income comes from swing trading stocks, so a consistently fast and stable internet connection is an absolute must. For my purposes, this Motorola MB8611 modem, in combination with my router, works just as well, if not better, than the modem I was leasing from Xfinity for $15 a month.

Verified Purchase

Perfect for Xfinity Users

I recently purchased the Motorola MB8611 DOCSIS 3.1 Multi-Gig Cable Modem through Walmart as part of my move to New Jersey, and I couldn't be more pleased with the entire experience. Walmart remains one of the most reputable and reliable retailers I've shopped with—smooth transaction, fast shipping, and everything arrived in perfect condition. I had done extensive research ahead of time and found that this Motorola modem consistently ranked among the top recommendations for compatibility with Xfinity service. I opted to use my own equipment rather than rent devices from my internet provider, and the setup process could not have been easier. Once my Xfinity service was active, I connected the modem with my own coaxial cable and paired it with a separate router. The modem powered up quickly, and the LED indicators were clear, easy to read, and user-friendly. Motorola continues to uphold its reputation for quality, and I'm confident this modem will serve me well for years to come. Highly recommended!
