ATT Internet Vs Cox – Charges
Equipment
Cox charges a $13 equipment rental fee for its Panoramic WiFi router. You can skip this charge by buying a Cox internet-compatible router of your own.
AT&T wins this category easily because the gateway device rental fee is already included in your monthly internet bill.
Both AT&T and Cox offer optional WiFi range extenders you can connect to your modem for better coverage. AT&T charges $50 while Cox charges $130 for the range extender.
Installation
Both AT&T and Cox have a one-time professional installation charge of $100.
If you subscribe to Cox, you can skip this fee and request a self-installation kit that walks you through setup without needing a technician.
AT&T also offers a free self-installation kit, but it’s not available in every area. You’ll need to contact AT&T to find out if it’s an option at your address.

To find the best ISP deal, it’s always smart to check what promos are running at the moment. Most of Cox’s perks are reserved for bundle subscribers.
AT&T has a web-only promo for a $200 gift card when you sign up for their internet services.
On top of that, AT&T offers a $15 per month discount to first responders, military servicemen with proof of service, and students.
Low-income households and senior citizens can also get discounts through AT&T’s Access program.
Cox has a prepaid internet service for low-income households called StraightUp, which gives you internet for $10 per month.
AT&T Internet Vs Cox: Pricing and Speeds
AT&T has built out a relatively large fiber network compared to its competitors, and the speeds in those areas are excellent.
Still, most AT&T subscribers are on DSL internet, which is stable but slower than fiber or cable.
Bundles often make AT&T fiber internet a strong alternative to rival services, especially since the actual performance tends to be better than what competitors offer.
Cox delivers fast internet and TV at prices that won’t break the bank. While Cox relies on cable (coaxial) technology, it manages to match AT&T fiber speeds in some areas.
Cox is a solid option for students since there’s no contract tying them down. With that in mind, let’s look at how the prices and speeds of these two ISPs compare:
