Why Asus Router Guest Network Not Working

Under normal circumstances, the guest network doesn’t work because you set to disable it after running for a specific period.

It’s inactive for some time, and you’ll need to activate it. There is also a possible conflict with another device on the network.

When your Asus router guest network stops working, it could be because you are using an incompatible network driver.

You need to set up the guest network properly to fix the issue.

1. Can’t Acquire IP Address

The router has problems issuing an IP address to your device. An IP configuration failure may occur, so you cannot join a WiFi network.

2. Issue With Browser Cookies

When you use a browser, it saves some info into its cache and cookies. Sometimes, the problem originates from these data.

3. Guest Network Not Set Up Correctly

The router does not have any DHCP function when in AP mode. It means it cannot manage the devices that connect to it.

4. Minor Software Glitches

When a device has been running for a long time, it collects bugs and saves them into the cache.

These minor software glitches can cause problems, including guest networks not working.

5. Outdated Firmware

Regular updates are necessary so your device will work smoothly. If out of date, you will miss out on important bug fixes.

These are the possible reasons your guest network on the Asus router isn’t working. Let us now proceed to the solutions.

How to Enable Guest Network on Asus Router Not Working

Before we go ahead with the solutions to fix guest network access on your router, let’s explore a few quick ways to resolve this issue.

You first need to reboot your router and see if you can now connect to the guest network.

You can also try forgetting the network on your phone and reconnecting to it. These two quick steps will usually suffice and fix connectivity problems with your router.

However, if these don’t work, let’s go ahead and work on the rest of the solutions.

Solution #1: Discharge Your Router via a Power Cycle

The next step you’re going to take is to discharge your router via a power cycle completely.

Your router has a RAM module that provides a temporary storage area for configuration and other files.

If you’re having trouble logging in to your router, the files in its memory are likely corrupted.

The only way to get rid of the contents of your router’s RAM is to discharge it. Reboots can only clear it to a point.

However, a power cycle with your router unplugged will completely remove any files causing the issue.

Here’s how to discharge your router:

Switch off your router.
Unplug it from the wall outlet.
Wait for at least 2 to 5 minutes.
Plug it in and turn it on.

Note: After power cycling your device, we recommend waiting for your router to connect to the internet and fire up its WiFi radio before connecting.

Solution #2: Clear Your Browser’s Cache and Cookies

Guest networks are an amazing way to share WiFi without compromising your network’s security and privacy.

Plus, it allows you to share the internet without giving out your WiFi password.

To log in to these guest networks, you’ll sometimes need to go through a portal using a browser.

If it’s only you that can’t log in to the network, you’ll want to check your browser’s cache and cookies, as some of them can disrupt your connection with the router.

Here’s how to clear your browser’s cache and cookies:

Open the browser you’re using to log in to the portal.
Go to More Settings.
Select History, then Clear browsing data.
Choose the All Time range.
Check the boxes for Cookies and Cached images and files.

Note: Even if you’re not connecting to any guest network portals, we recommend clearing this every couple of months.

Solution #3: Enable DHCP on Your Devices

Networks either require you to set IP address acquisition automatically or manually.

Since they’re temporary, guest networks will need you to use automatic IP addresses.

However, there are cases when a user of your guest network has a device set up to use static IP addresses.

If this happens, it’s up to the device to adjust and set to DHCP rather than static.

These are all simple steps that should not be much of a hassle in exchange for access to the internet.

Here’s how to enable DHCP on your devices:

For iOS devices:

Go to Settings, then General.
Select WiFi.
Find the guest network you’re connected to.
Tap on the i icon opposite the WiFi name.
Select the DHCP tab, and tap on Save.

For Android devices:

Go to your phone’s Settings.
Select Network & Internet, then WiFi.
Press and hold the WiFi network you’re connected to.
Choose Modify network.
Go to Advanced options, and select DHCP.

Note: You’ll still be able to change some settings, like DNS servers.

Solution #4: Set up the Guest Network with 2.4 GHz WiFi

If your guest network doesn’t work, it’s likely that it’s not set up correctly.

Since those connecting to your network are not permanent users, you won’t know the hardware they’re using.

To be on the safe side, we recommend setting your guest network and only using 2.4 GHz.

This way, you won’t have to worry about incompatibilities since all devices with WiFi can connect to this band.

Here’s how to set up the guest network with the 2.4 GHz band:

Login to your router’s web interface.
Select Guest network, then click on Enable.
Enter the details of your network.
Select the 2.4 GHz frequency band.
Click on Apply to complete the setup.

Note: You can also set passwords for your network and even set time limits to how long devices can connect.

Solution #5: Update Your Router’s Firmware

Guest networks are also affected by everything else your router is doing. If your guest network stops working, you know that there’s something wrong with your router.

One of the quick ways to resolve issues like this one is by checking your router’s firmware.

Outdated firmware can cause some of your router’s functions not to work properly.

Sometimes they affect your configurations, and there are times it’s your guest network.

If you’ve tried a few other solutions that eliminated other devices as the cause, it’s time to look at your router’s firmware.

Here’s how to update your router’s firmware:

Log in to your router’s web interface.
On your router’s Home page, check the top-right for notifications.
If an update is available, you’ll see it there.
Check the pop-up message and click on Update now.
Select Firmware update.

Note: After updating your router’s firmware, we recommend power cycling it before testing to see if it resolves the issue.

Solution #6: Reset Your Asus Router to Default Settings

These solutions should get the guest network up and running again. However, if you feel like you’ve tried everything, you can still go for the reset option.

This will revert your router to its default settings, removing all your data and configuration.

It’s not the most elegant of solutions. However, it’s one that can give you a high success rate.

Here’s how to reset your router to default settings:

Log in to your router’s web interface.
Go to Administration, then Restore/Save/Upload.
Select the Restore button.
Click on OK to confirm the reset.

Tip: You can also reset your router using the physical Reset button found at the bottom or back side of your router.

There you have it! These different solutions will allow you to fix your guest network issues in no time.

These should help you get to the bottom of the problem without wasting a lot of time.

If you continue to experience any errors with your guest network, contact Asus support to get additional help.

Bottom Line

Now that you know the different causes of your Asus router guest network not working, you can use this knowledge to fix it.

Follow the proven steps, and you should be able to get your guest networking working again in under 10 minutes.
