It seems impossible to live in this day and age without a speedy internet connection. Whether it’s work or any other leisure activity, you can manage to do most of those, if not all, by means of an internet connection. This emphasizes the importance of the internet in our lives and how it can affect our day-to-day. So, besides an internet connection, what else do you need to enhance your lifestyle? One of those things is the right updated modem to keep up with your internet speed.

Now, modems can be a bit tricky sometimes. Usually, they don’t cause many problems once they’re set up properly. You don’t need to turn it off and then on every day just like a laptop or do something else unless there is a problem. If they do cause a problem, it is something that can easily be resolved by you. Of course, you can still choose to call a technician or an expert if you are unsure of what to do.

The most common problem you can face is slow internet speeds, and the reason for that can be anything ranging from channel overload to hindrances between your modem and any other devices or signal blockages. If your modem is placed in a central location and is not surrounded by any barriers, then your problem might just be due to channel overload.

In this blog, we will be talking a bit about this problem and then its solution. However, the only addition here will be that we will be talking about it in the context of a CenturyLink modem. Why CenturyLink specifically? It’s because CenturyLink has garnered many customers as it is widely available in rural areas just as much as it is in urban areas. Not only this, but CenturyLink offers unmatched high-speed Fiber and DSL internet services to satisfy your need for speed!

CenturyLink is one of the top 5 largest ISPs in the U.S. in terms of DSL and Fiber internet services. It is available to residential households and business customers in 36 states and if we were talking exact numbers, it has a footprint of over 4.5 million subscribers!

We have already mentioned that CenturyLink Internet offers two connection types: DSL and Fiber. CenturyLink Fiber Internet is not so widely available as of yet due to the expensive infrastructure and some other problems. However, CenturyLink has been working continuously to expand its fiber network to allow more and more people access to fiber internet.

Some states where you will find CenturyLink Internet widely available are Arizona, Colorado, Washington, Minnesota, Florida, North Carolina, and Oregon.

We have already discussed why you would need to change the channel on your modem and so, in this section, we will talk about how to do it. To make things simpler for you, we have made a list of steps so you can follow accordingly.

  1. Connect one of your devices, laptop, phone, or tablet to the internet.
  2. Open your preferred web browser and in the search bar, enter the link into the address bar or just copy and paste it. Click enter.
  3. In the settings interface, type in the Username and Password. Note that these will be your admin credentials and they are different from the password key or Wi-Fi SSID.
  4. From the main menu, find the option for Wireless Setup.
  5. Then, select the option 4 GHz in the left sidebar.
  6. Next, click on Radio Setup.
  7. Choose a channel from 1-11.
  8. Next, choose a wireless power level, accordingly, ranging from 10% to 100%. The lower settings create a better circular coverage on a shorter signal range only. Whereas, the higher settings create more of an elliptical coverage area with a longer range. The coverage closer to the modem will be reduced, however.
  9. Select the right 802.11 mode.
  10. Click Apply and save the changes.

The Difference between 2.4 GHz and 5 GHz Wi-Fi

There are two frequencies you can select: 2.4 GHz and 5 GHz. How do you know which one to choose and what is the difference between the two of them? We will explain the differences between them so you know what to get based on your internet connection.

2.4 GHz

This frequency has a larger coverage area and is relatively better at penetrating solid objects. However, it has a lower data rate and is more prone to interference. The reason for the interference is that a lot of devices operate on this frequency.

5 GHz

This frequency has a higher data rate and it is less prone to interference as not a lot of devices use this frequency. It has a smaller coverage area, however, and is bad at penetrating objects as well. In a sense, it is the opposite of 2.4 GHz.

Which One Should You Choose?

The 2.4 GHz connection tends to travel farther but at lower speeds, while the 5 GHz connection covers a short range with higher speeds. So, the decision ultimately depends on your level of internet usage and also, where your modem is located. It also depends on the other devices you have in your home like microwaves, security cameras, and a radio. Since most electronic devices operate using 2.4 GHz, your internet connection can be disrupted if you select the 2.4 GHz frequency.

Our suggestion: If your modem is centrally placed and in such a way that everyone is able to use the Wi-Fi close to the modem, then 5 GHz would be the right setting for you. This frequency is good for you especially when you have to perform high-bandwidth activities like gaming, streaming, etc., in which case you should sit as close to the router as possible or directly connect your system with an Ethernet table. However, if you move around a lot or cannot be close to the modem for long periods, 2.4 GHz is the better option for you.

Knowing all of the things, naturally, the next thing you want to know is which CenturyLink modem should you get? Or maybe, you already have one and are looking to switch to a new modem? Whatever the scenario, check the list below:

Technicolor C1100T

Technicolor C1100T supports 2.4 GHz 802.11 Wi-Fi. Its IP compatibility is IPv4 and IPv6. This modem is also compatible with secure Wi-Fi.

Actiontec C3000A

This modem is compatible with IPv4 and IPv6 and it supports both, 2.4 GHz and 5 GHz 802.11.

C4000 (all models)

All models of C4000 support Wi-Fi 6 technology and support dual-band 2.4 GHz and 5 GHz. In case you’re wondering, they are all secure Wi-Fi compatible as well.

To End Things Off

This brings our discussion to a close. While it may seem that changing the channel on your CenturyLink modem is a difficult process, it is, in fact, very simple and we’ve laid out the steps for you as simply as possible so that you don’t have trouble following along. If, in any case, you still run into a problem, you can still contact CenturyLink customer service at 1-855-349-9310 and ask for tips or call an expert. You can also find help on their website in the form of online resources.

You can also try and see for yourself what the problem is and if it can be easily resolved. How you can check the problem and resolve the issue, you can find that out here!

Frequently Asked Questions (FAQs)

How do I change channels on my CenturyLink modem?

Connect your device to the internet and open a web browser. Enter in the address bar and type in your username and password. Select the wireless setup from the main menu. After that, select 2.4 GHz or 5 GHz in the left sidebar and then click on radio setup. Select a channel from 1 to 11. Choose a wireless power level from 10% to 100% and then select the right 802.11 mode. Lastly, click apply and save the changes.

Which Wi-Fi channel is better for CenturyLink modem, 2.4 or 5?

If you want a bigger coverage area for your devices and can cut down on the speed, use 2.4 GHz. Otherwise, if you can sacrifice on the coverage area and not on speed, 5 GHz would be better for you. The 5 GHz frequency can also cut through any interference to maximize the network performance.

Can I use both 2.4 and 5 GHz at the same time?

You can only use both Wi-Fi channels at the same time if you have a dual-band router and if your wireless devices support both bands. If one of these conditions is not true, then you won’t be able to use both and will have to choose one.

How do I change my channel to 5 GHz?

You will have to select 5 GHz in the left sidebar of the wireless setup on the main menu. To get to the main menu, you will have to type in the address bar of your web browser. Next, you will enter your username and password and you will be redirected to the main menu.
