Cannot connect Xbox One S with 5GHz Wi-Fi

You could always open the browser on each console and run a generic speedtest. Pick the nearest server provided and compare.

Wired Ethernet Spec is the same across the consoles:

Xbox One X Xbox One S Xbox One

Ethernet IEEE 802.3 10/100/1000 IEEE 802.3 10/100/1000 IEEE 802.3 10/100/1000

Wireless is where they diverge

Xbox One X

IEEE 802.11ac dual band (5GHz & 2.4GHz), 2x2 wireless Wi-Fi with Wi-Fi Direct for home networks

Xbox One S

IEEE 802.11ac dual band (5GHz & 2.4GHz), 2x2 wireless Wi-Fi with Wi-Fi Direct for home networks

Xbox One

Dual band 2.4GHz and 5GHz spectrums, compatible with IEEE 802.11/a/b/g/n networks

In addition to this.. to give you an idea of distances involved here, 2.4ghz range is around 30 metres from your router before its begins to degrade in quality. 5ghz range is only 10 metres from the router before quality drops hugely.

Some routers also begin to have drop outs or lag as you have described if a device is within the outer near 10m range of the 5ghz channels.. as it tries to continually connect to both networks as the quality of one drops against the other etc.

My router had this issue and I turned off the 5ghz access altogether, my console is now connected by ethernet also and no further issues for me.

If you can hardware up with an ethernet cable.. thats always your best option.. if you do suffer dropouts, turning the 5ghz setting off on your router can help ease that also in some cases dependant on brand of the router equipment, then just connect to
the 2.4ghz as normal. Hopefully the laggy behaviour will subside.

Hi there LittleAdam1,

Thanks for reaching out here in Xbox Forums. I understand there is an issue with trying to connect the Xbox One S with your 5GHz Wi-fi.

The 2.4 GHz band provides coverage at a longer range but transmits data at slower speeds. The
5 GHz band provides less coverage but transmits data at faster speeds. The range is lower in the
5 GHz band because higher frequencies cannot penetrate solid objects, such as walls and floors.

I recommend trying the following article:
"I am experiencing slow performance when playing games on Xbox Live." If the issue persists,
Contact your ISP to discuss your bandwidth allocation.

Try this out and let us know the results.

Hi,

We appreciate the time and effort you spent on replying to our message.

So your saying that you can connect to the 5GHz Wi-Fi as of the moment, correct?

To clarify as well, is the 2.4GHz and 5Hz Wi-Fi is just from 1 Internet connection?

SIncerely,

Hello Etanarvazac R, My name is David. I am an independent advisor, happy to help you today.

Yes, it is possible that the Xbox One S (XO) may have limitations when it comes to connecting to 5GHz networks broadcasting on DFS (Dynamic Frequency Selection) channels, such as channel 116. DFS channels are subject to regulatory requirements because they share the same frequency range as certain radar systems, and as a result, devices need to meet specific criteria to operate on these channels.

The Xbox One S and Xbox Series S may have different Wi-Fi hardware capabilities and firmware support, which could explain why the Xbox Series S (XS) is able to detect and connect to the network on DFS channel 116 while the Xbox One S (XO) cannot.

To confirm if the Xbox One S is indeed unable to connect to DFS channels, you can try the following steps:

Change your router's 5GHz channel: Set your router to a non-DFS channel that is within the supported range of the Xbox One S (e.g., channels 36-48 or 149-165). This will help determine if the Xbox One S can connect to the network on a non-DFS channel.

Update the Xbox One S firmware: Make sure your Xbox One S is running the latest system software and firmware updates. Sometimes, firmware updates can include improvements to Wi-Fi connectivity and compatibility.

Best regards.
