Packet loss in Cox

Cox Communications, or simply Cox, is an Internet Service Provider (ISP). It provides several communication services such as digital video, home security, home phone, and high-speed Internet.

The latter is the one that we’ll focus on since our guide aims to give you the know-how on packet loss, help you understand what are its most common causes, and how to fix it without too much effort.


What is packet loss in Cox?

Packet loss occurs whenever packets that you send or receive never make it to their destination. With Cox, things aren’t too much different, except that this packet loss phenomenon occurs on the Cox network.

You must understand that packets can leak anywhere on your connection. Say, for instance, that you connect to Google. Between you and the destination server, there might be several hops.

Packet loss can occur on either one of the nodes we’ve talked about, or even on multiple ones. More so, packet loss can range between 0-100%, 100% being the most severe case (no connection).

What can cause packet loss with Cox?

As with any other ISP or service, packet loss can be caused by a wide variety of factors.

The only thing that Cox might do differently is limiting your bandwidth (which, subsequently, might lead to some packet loss) or allocate network resources improperly.

One thing is certain, though: network congestion remains the most common cause of packet loss.

And that’s likely the reason why most users complain about packet loss during peak hours. The network is probably improperly configured, and servers can’t handle so many requests, so most of them get dropped.

As you may have guessed, this inevitably leads to packet loss.

Among other factors that might weigh in on the occurrence of packet loss, we remind of router errors, hardware/software issues, bad Ethernet cables, using Wi-Fi instead of wired connections, and even host errors (destination server).

How can I improve packet loss with Cox?

1. Try using a VPN

  1. Download Private Internet Access
  2. Install it on your computer
  3. Launch it
  4. Log into your account
  5. Connect to a high-speed server (low-ping one)
  6. Check if the problem still persists

If the issue is on your ISP’s side, then using a VPN will certainly at least improve, if not fix packet loss altogether. VPNs take your traffic and route it through their own networks, away from the congestion on your ISP’s network.

Private Internet Access

Private Internet Access is a great all-round VPN service from Kape Technologies that can easily improve packet loss.

However, it can do so much more than that, such as keeping your online privacy safe, securing your connection, and circumventing geo-restrictions.

2. Perform manual troubleshooting

  • Run a pathping test using CMD or Speedtest by Ookla’s packet loss testCMD pathping
  • Check and repair any faulty components on your home network (PC, router, cables, drivers)
  • Call your ISP (Cox) and see if there’s anything they can do about it
  • Contact the service you’re having trouble with if they’re the one losing packets
  • Try using a wired connection instead of wireless (Wi-Fi packet loss occurs more often)
  • Restart your router and/or modem
  • Try connecting straight to your modem or home line
  • Avoid peak hours, if possible

Cox packet loss can be sometimes fixed

All things considered, if you’re a Cox customer and experience packet loss, it might be due to network congestion. In which case, it might be a good idea to wait it out.

If that’s not an option you could try troubleshooting the network by yourself, or even using a VPN if you suspect the issue is caused by your ISP.
