The 5 Best Modems for Cox Reviewed

modem for cox

Not every modem you will find on the market is compatible with Cox. Also, not all Cox-compatible modems you see will be worth your money.

So why Cox? Cox is currently the third-largest cable internet service provider in the United States and has over 6 million active subscribers. The company is the most preferred by many, mainly because of the comprehensive service plan. Their service plan includes the following – Gigablast (1 Gbps), Ultimate (300 Mbps), Preferred 150 (150 Mbps), Internet Essential (50 Mbps), and Internet Starter (10 Mbps).

Cox also charges a rental fee of $10 per month, costing a client up to about $100 a year. Therefore, to wipe out this extra cost, it is recommended you get yourself a compatible modem. It would help if you found a third-party modem that you can use to produce better network performance with less demand on your electricity. Some of the third-party modems are easier to repair as compared to the Cox modems. That is why we have put together this review list of the best modems for Cox.
