5ghz Wireless Network Missing Suddenly - Hp15r-137

I have Windows 10 on a HP15r-137 (HP Touchsmart 15).

I recently upgraded my router to a netgear which is dual band. When I initially set it up, it saw both the 5g and the 2ghz network SSID's. I connected to them both and the 5G was faster. I was getting about 45mbps as opposed to about 64mbps on the 5ghz . So I left it connected to the 5g

Today I was trying to download something from the windows store and it was hanging. Thought it might be my network connection. Sometimes disconnecting and reconnecting helps. When I went to disconnect it was only connecting to the 2ghz and the 5g was not even listed. I thought that was strange. So I thought maybe shutting down the router and rebooting it would fix it. Nope my computer did not see the 5g in wireless connections.

So I checked my firestick and my phone. Both see the 5g and connect to it. I googled it and found that resetting the router by using the reset button helped most people. I did that. And my HP laptop still did not see the 5g connection. I went into the set up and tried a different channel. When I chose a different channel number then my laptop saw a "hidden network". It asked for the SSID. I put in my SSID of my 5ghz, and then the password. But it wouldn't connect. I thought that was weird.

I tried to add that wireless network connection manually. It was added fine. But still did not see it listed.

So another website said to check your network card and make sure it's capable of recieving 5g. I went into device properties and it says it's 802.11bgn. And that it's only 2ghz capable. Well obviously that can't be right otherwise I would not have connected to the 5g in the first place. So I went to the manufacturers website and looked at the specs. No where did it list 802.11a or 802.11ac which is the 5ghz capability.

So I'm dumbfounded as to why when I first set it up it saw it and connected to it. Obviously I have to have those capabilities otherwise it would not have initially seen it and connected to it. I'm just trying to figure out why my laptop is not seeing it any longer. I have tried all solutions that I know and nothing is working. My driver for my wireless network card is up to date and the firmware for the router is up to date. My adapter for wireless network is Realtek RTL8188EE.

Anyone have any other suggestions?

Thanks so much!

This page indicates it is a single band 2.4ghz only adapter:

If the Wireless Card is b/g/n single band it will only work at 2.4 GHz. That's what the specs for that model say.

You can double check by looking up the Wireless Chipset independently. Realtek RTL8188EE is b/g/n single band 2.4 GHz only.

I have a Netgear Router that is b/g/n/ac dual band and have the ac 5GHz setup on that. However nothing is listed in the 5G Wireless Devices, nor statistics not surprisingly as I know currently no ac hardware is being used.

You were obviously mistaken when first setting up the Netgear router.

I have both SSIDs set to different names, and I've tried different channels for the 5g lower and higher. Nothing works. My router is a Netgear AC 1750 Smart Wifi Router R6400.

I know that when I first set it up, I definitely saw the 5G listed on my laptop and connected to it. I wanted to see how much faster the speeds were between the two. And I did see that the 5G was faster. I switched between the two, and I just kept it on the 5G. The specifications may not list 5G capability but it may have the ability. I know that I have had at least one if not two windows updates since I first hooked up the netgear. It could be that something with the update messed something up. I don't know.

I will be emailing Realtek directly regarding this issue to see what they have to say or any ideas they may have.

Just not possible, and that is it. The end.
I use a D6400 here so I know what statistics that can display.
