HP Omen Wifi Does Not Show 5GHz SSID of Router

[A4Apollo]

@autumn2018, thanks for your quick response and time.

I appriciate your efforts for writing back to us.

As you know WLAN is country specific.  5GHz is not allowed in all countries, but there is some more explanation:

5GHz is categorized into two categories: with ISM & UNII:

In ISM 5GHz is having a range 5.725GHz to 5.875GHz and used for the outdoor environment.

In UNII 5GHz: UNII Band is of three types i) UNII-1, 2.a)UNII-2, 2.b)UNII-2Ex., 3)UNII-3.

Out of all the above UNII bands only UNII-1 is recommended (used) in indoor environment because of power level (max. 50mW).

So, it could be possible in your country 5GHz is allowed, but check this is ISM or UNII.

If UNII-1 is not allowed, your PC may be compatible with 802.11n but only for 2.4GHz not with 5GHz (UNII-1).  If this is, you will not even see SSID in your PC.

Also, Nearly half of the frequency range of the 5 GHz band requires dynamic frequency selection (DFS), a process by which the access point must detect the signature of existing government weather radar and other radio systems and vacate the channel for an hour. If a particular WiFi network is located in range of such an existing radar system on a DFS channel, the particular DFS channel is unusable at that location, and channelization must be redone to avoid that specific channel.

In March 2014, the Federal Communications Commission (FCC) extended DFS detection requirements to apply to client devices as well. Unfortunately, many WiFi consumer device and appliance manufacturers, driven by cost and time-to-market constraints, took the easy way out: simply do not operate on any channels in the DFS channel range. This significantly limits the practical number of channels available if those client devices are on the network, especially when channel bonding for larger channels. But don’t worry: All of your Apple and virtually all of your Android smartphones and tablets currently support operation on DFS channels. The problem is with low-end laptops and wireless USB adapters, which will revert back to 2.4 GHz operation if they cannot see a 5 GHz signal because the AP is using a DFS channel.

Please find the image attached below to know more about frequencies supported.

No, this does not solve my problem.
1. As you can see, channel 149 and above are not in DFS range.
2. I am in Singapore, and my router is provided by the biggest government linked company, SingTel. It certainly operates in government approved frequency ranges.
3. All of my other devices are able to see my 5GHZ SSID at channel 149, (the channel is automatically chosen by router)
4. My OMEN was purchased in Singapore, hence I expect it should work fine in Singapore's wifi environment.
5. As to my understanding, the OMEN is definitely NOT a low end laptop, if I believe what HP website says about this model.

Therefore, I need a definite answer from HP, that for my OMEN model (see the product number in the first post), is it supposed to be able to work with Singapore 5GHz wifi frequency range, including the channels I listed in my previous email.

@autumn2018, Thanks for your quick reply again.

If you check the image from my previous post the wireless card shipped with your PC is an 802.11n card.

And to work with frequency of 149 and above you need UNII-3 supported wireless card.

The card that is shipped with your PC is a UNII-2 or UNII-2e supported wireless card, so you cannot connect to a frequency beyond 149.

If you still think your answer was not answered, please contact HP phone support and get assistance.

Take Care!

Have a great day ahead! 🙂

This was what you said in the post regarding my product number:

"
I have checked the specifications of your laptop and your laptop was shipped with 801.11 AC wireless card.
"

Note it is 801.11 AC, not 801.11n.

Here is the card details:

Is this a UNII3 capable card?

[A4Apollo]

@autumn2018, Thanks for the reply.

If you check the image again even though if have an 802.11a or AC wireless card on your PC.

It still needs UNII 3 supported wireless card. And the wireless card shipped with your PC is a UNII-2 or UNII-2e.

If you have any more queries, please contact HP phone support and get assistance.

Link to contact HP.

Have a great day ahead! 🙂

Is this limitation mentioned somewhere in the product specification of my laptop model?

If not, how could a customer know this before he/she purchase this laptop?

I am a technical savvey person, if you agree. Even for a person like me would expect the laptop to work with local 5GHz channels (UNII-3), how could a average layman know this limitation?

I would like to make informed decision for my purchases, If there is such limitation, it should be spelt out in the specification.

BTW, even my ultra low-end SGD150 handphone is UNII3 capable, it is a shock that the HP OMEN gaming laptop is not.
