Update;
I was able to once again borrow a friends iPhone so I could reset the Altas PT Ultra camera and go through the set up process again.
Once I went through this process, the camera is currently connecting to the Reolink Client on a more consistent basis.

@sibedad This supports WIFI 4, 5, 6 and 6E respectively. So you should have no issue to connect any of the Reolink cameras to your router. Ensure that your configuration is correct and there is no firewall.

We already told you so in Reddit Reolink.

A direct quote from my chat conversation with Axle from Reolink Support regarding Argus Track and Wi-Fi 6 on October 11,2024:
"Upon checking the Nokia FastMile 5G Gateway 3.2 supports Wi-Fi 6 (802.11ax)
Which the Argus Track can't connect because it only can connect to Wi-Fi 5"
======
This is an issue long resolved, as I returned the Argus Track the day after this conversation. However, you and others keep mentioning this resolved issue, which was not the point of my frustration with the Altas PT Ultra, which has also been returned and replaced by an Argus Track Mix, which I am currently testing, with no connection issues whatsoever! Thank You.

@crimp-on_62210811129 That is not the information Reolink Support gave me when I had the Argus Tracks and was trying to connect it to my Nokia FastMile 5G Gateway 3.2 router which is Wi-Fi 6. Reolink Support stated that because the Argus Tracks was Wi-Fi 5 it would not connect to my NOKIA router.

I chose Reolink due to good product reviews and the fact they had a PC Client, as I do not have a Smart Device to be able to use an App.

I first ordered a Reolink Argus Track from Amazon.ca, in early October 2024. The camera was easy to set up to the Reolink Client, however it would not connect to my Wi-Fi? After contacting support I discovered it was not Wi-Fi 6 compatible. This was not mentioned in the product description. I returned it to Amazon.ca and was refunded in full.

I researched Reolink Wi-Fi 6 cameras and was pleased to find a new model, the Altas PT Ultra with solar panel, which was also a battery powered solar camera. Amazon.ca did not yet have this camera listed, so I placed an order directly from Reolink Canada...my first mistake!

Reolink contacted me through Amazon.ca, regarding my return of the Argus Track, offering a return and refund. When I explained that I had already returned, been refunded, and had ordered the Altas directly from Reolink, they offered me a partial refund on my Altas purchase, to make up for the inconvenience...I was pleasantly surprised and thought, "great, I am dealing with a company that stands behind it's product!"...my second mistake!

Immediately upon arrival of the Altas PT Ultra my frustrations began. This camera, unlike the Argus and other Reolink cameras, required a Smart device to initialize, to be able to connect to the Reolink Client. I do not have a Smart device, my first reason for choosing Reolink! I had to bother a friend to borrow his iPhone to install the App and initialize the Altas.

Once initialized and connected to the Reolink Client, my frustrations continued. The Altas would not consistently connect the the Client. I would have to open and close the Client several times, or even delete and reinstall the camera to get a connection. I contacted Reolink Support in hope of a resolution, this was on October 22nd. I should have pack the camera up and requested a refund, I did not...my third mistake!

What followed was back and forth e-mails, between several different "support/customer service" personnel, each asking the same questions over and over again, and me patiently providing the same responses! Each time Reolink thanking me for my patience and apologizing. I had patience as I had confidence that this being a new product, they would eventually be able to resolve the connection issue.

In the meantime, I ordered another Reolink camera, E1 Outdoor Pro, from Amazon.ca to cover another area on my property. This camera being a wired, not battery, camera worked and connected flawlessly with the Client.

After going back and forth regarding the Altas PT Ultra connection issue with Reolink, on December 3rd, Support passed me off to the "after sales team" to contact me for a resolution. The Reolink Warranty Team offered to replace the Altas PT Ultra with the same model. So I packed up the original Altas and shipped it back to Reolink, at their request, and at a cost of $37.66, a cost I assumed Reolink would cover...my fourth mistake, they have not!

The replacement Altas camera arrived on December 13th, and after again borrowing my friends iPhone to initialize, the connection issue to the Reolink Client was no different! I requested a refund and stated I would use the refund to purchase another Reolink wired, not battery, camera, as it seemed to me the fact the Altas was a battery camera was the issue.

Confident of the refund from Reolink I ordered a Reolink Track Mix Wi-Fi camera, a wired camera of equal value and features to the Altas, from Amazon.ca, which arrived the very next day...my fifth mistake!

Reolink's response to my refund request: 
"We sincerely apologize, but we are unable to process a refund for orders placed over 30 days ago. However, we can assist you by exchanging your product for the E1 Outdoor Pro and covering the shipping costs for the exchange."  
My level of frustration was mounting! It was because of my patience and confidence that Reolink would resolve the connection issue that my refund request was past the 30 day policy! In turn they were offering a replacement camera of lessor value and features!

I explained that I had already purchased a replacement camera, to which Reolink replied:
"We sincerely apologize for the inconvenience this has caused you. However, according to our after-sales policy, we are unable to process refunds for orders that exceed 30 days. In this case, we can only assist you with an exchange."  
Reolink then offered to replace the Altas with another Track Mix Wi-Fi, not the one I had already purchased and received from Amazon.ca, meaning that camera would have to be returned to Amazon.ca!

Reolink's "assist you with an exchange" was a $30.00 refund to supposedly cover shipping costs. The cost to return the Altas and solar panel came to $50.24! The replacement Track Mix is scheduled for arrival today!

So, after two months of frustration dealing with Reolink, I am out of pocket some $57.90, for return of their faulty product, and the hours of time spent going back and forth!

When my current Reolink cameras fail...and I am confident they will, you can rest assured they will not be replaced by another Reolink product. Buyer Beware!

Further Update:
I am still having issues with Altas PT Ultra connecting to Reolink Client. Most times I have to open, close, and reopen client several times before the camera will connect. Very frustrating!
I recently added an E1 Outdoor Pro to the client and this camera connects every time I open the client and this camera is located further away from the router and has a weaker Wi-Fi signal!
What is wrong with the Altas? Are others experiencing these issue...or am I alone with this problem?

Update;
I was able to once again borrow a friends iPhone so I could reset the Altas PT Ultra camera and go through the set up process again.
Once I went through this process, the camera is currently connecting to the Reolink Client on a more consistent basis.

@joseph_1979 Apologies for delayed reply...I am new here and only allowed 1 post/day! Silly!
The camera is only about 10-12 feet from the router, any closer and I would have to bring it inside. It is mounted under my deck just below where the router sits inside the house. Thanks for the suggestion.

I have just reset and and set up the camera again. I have not been able to try this in the past two weeks, as I have to borrow a friends iPhone, which I had to use to set up the APP, as I don't use or have a smart phone...thus the importance of the Reolink Client on my laptop. 

I may have stumbled across a possible solution today. I will do some testing and give it some time and update here...if it keeps working.

I purchased the new Reolink PT Ultra two weeks ago and I am using the Reolink Client on a Windows 10 Laptop to attempt to view the camera. I say attempt as the camera will not stay connected to the Client.
Once I finally get the camera connected to the Client all is fine...until I close the Client. When I reopen the Client the Altas "fails to connect". The only means to get a reconnection is to delete the camera and shut down the Client, then it takes several, usually at least 6 attempts to add the camera and reconnect to the Client. Both support and customer service have been involved in trying to resolve this issue and have had me going in circles for the past two weeks, with no progress.
Has, or is, anyone else having this connection issue with the Altas PT Ultra and Reolink Client? If so, were you able to resolve?
This is my 2nd Reolink camera, the 1st I had to return as it was not Wi-Fi 6 compatible, and my 1st use of the Reolink Client. Not having a positive experience!

@reolink-daisy I don't see how to set up Pre-record Mode in the Reolink Client. Please provide instruction. Thanks.

I specifically chose Reolink because it has a client that I can link a camera to my Windows laptop, as I do not have a smart phone.
Imagine my frustration when I received my newly released Altas PT Ultra and could not connect it to my Reolink Client! After contacting support I was informed the camera had to be initialized on the Reolink App prior to connecting the the client! I had to have a friend with an iPhone install the app in order to initialize my camera, then I got it connected to my client. Yeah! The next day my camera would not connect to my client! Now I am being told, buy support, I have to reset my camera, reinitialize on my friends phone, add camera to client then delete camera from client and reconnect to client manually! So now I have to bother my friend yet again!
Please remove the requirement to initialize in App before adding to Client. A previous Reolink Argus Track did not have this requirement or issue!
