OverviewCox Communications is one of the largest telecommunications organizations in the United States. It has 3.5 million people signed up for its internet services throughout 18 states. The company is headquartered in Sandy Springs, Georgia.Cox first started offering high-speed internet in 1996 and has since grown into a cable internet provider that features speeds up to 1 Gbps (that's 1,000 Mbps). The plans are straightforward and don't have a lot of surprises. Most of them will support smooth video streaming, although you may encounter some problems during high-demand times if you have a lot of people in your neighborhood using the cable lines.ProsStrong selection of high-speed plansMost plans sufficient for streamingPanoramic Wi-Fi to address dead zonesConsPlans pricey compared to similar service tiers offered by competitor ISPsSlow upload speedsDownload speeds are affected by usage in your areaServiceCox Communications offers five speeds of cable internet service, many of which are sufficient for video streaming. Since Cox internet relies on a cable connection, the actual speed that you get depends on how many people in your neighborhood are using that bandwidth at the same time. During peak periods, you may experience slowdowns that result in speeds that are significantly lower than your plan's advertised speed.Speaking of Cox internet speeds, they start at 5 Mbps and go up to 300 Mbps. Customers in limited markets have access to Cox's top speed option of 1,000 Mbps.Cox doesn't have the most impressive service offerings on the market, at least not for the price: other ISPs offer similar speeds for less.One unfortunate characteristic that all Cox internet plans have in common is an upload speed that's 10 percent or less of the download speed. If you like to do video calls or upload large files, then you may need to get a higher tier plan than you were originally intending.If your house is prone to a lot of Wi-Fi dead zones, Cox may be a good choice for you. Cox offers a Panoramic Wi-Fi add-on to end the Wi-Fi dead zone problem. The Panoramic Wi-Fi uses extenders to replicate your signal throughout the house, so you have coverage even in locations that are far away from the router or separated from the router by walls and floors. Customers that choose Panoramic Wi-Fi have to get it professionally installed by Cox.The Cox Connect app gives you mobile control over your Wi-Fi network so you can troubleshoot issues and keep an eye on its status without going to your computer.Customers with service at Cox's 100 Mbps tier or higher can enjoy internet on the go when they connect to any of Cox's 500,000 Wi-Fi hotspots. This benefit means you won't have to rely on your mobile data or hotel internet for a connection — which is good news for cord cutters, as streaming may be costly or poor quality on those sorts of connections.The Cox Security Suite Plus helps you keep your network protected with an anti-virus program, firewall and other internet security features. McAfee is the company behind this software, and it supports five devices. You can keep Windows and Mac computers, Android mobile devices and iOS devices secure.If you need an email account, Cox has you covered: you'll get 10 email addresses with a minimum of 2 gigs of storage included.Cox Communications also has bundles available with television and home phone service.Customer ServiceCox's customer service isn't the worst out of large internet service providers, but it's also not going to win many popularity contests.
