connection issues with Realtek RTL8852AE WiFi 6 802.11ax PCIe Adapter

[THETIFFIN]

This page is a litany of incompetence -  who of Microsoft, HP, Real tech  -  will take responsibility??

Does HP monitor this page?  As far as I am concerned I have an nonworking computer which I'll have to return -  I do have to earn my living.

I think HP knows about this problem and this thread. I wrote to them and provided a link to this thread as evidence that the card was defective. As you can see, it doesn't matter to them. After the last driver update (6001.0.10.339), the range of the network card improved, but the connection instability remained. I think that they artificially increased the connection quality on the controller, and the network card itself is simply faulty.

but the link speed still is not near wifi 6. only stays at 1201/600 Mbps compared to my intel wifi ax201 links at 1201/961 Mbps or higher.

I have same symptoms as all others.  I disabled the Realtek adaptor and plugged in an old Ralink USB 2.4G adaptor to the USB port.  Wifi stability does not really seem to be any better, although more bars are certainly visible.  Could there be some problem other than the Realtek adaptor?

Here's a link to the 339 driver:

What worked for me was going into the Device Manager and disabling the 2.4 wifi mode for the adapter. I also played around with the 5g mode a bit, setting it to a/n/ac or just a/n. Changing the driver didn't do anything for me. Funny enough, now when I set everything back the way it was, it works just fine! What the hell. I've had this Laptop for 2 months, and just started playing an online game today. My ping was not great, and every minute or 2 It would skyrocket and I'd lag like hell. I pinged my router and was getting reponses from 30-60ms, with spikes going up to 300ms. Now after the changes it's down to 1 or 2ms most of the time. The signal strength is great as well now. I always wondered why I'd only get a bar or two when i'm not even that far away. Always blamed it on interference. I can finally bash some heads in chivalry2!

Thank you Qntario.  Disabling the 2.4 band in device manager seems to have worked for me as well.  The wifi connection on 5 GHz only shows one bar (there are three walls between the laptop and the router), but it still gets me more than 50 Mbps, which is plenty for what I need.

Hopefully this help folks that are still having issues.

I am currently using a driver v.6001.0.10.334 that I downloaded from Lenovo website. The only settings I changed on the driver details are the wake up ones, which I disabled. https://support.lenovo.com/us/en/downloads/ds552846-realtek-wifi-driver-for-rtl8852ae-for-windows-11...

The installer offers an option to extract files without installing, and that's what I did first and followed with "have a disk" option using the "Update driver" button in the Device Manager.

One thing I've noticed when trying to troubleshoot this myself (no thanks to HP's tech support) is that the problem is much worse when the laptop isn't plugged in to power. It's pretty easy to test - ping times are much shorter when I plug in the power cord than when I unplug it. Pinging my router, I get ping times of 3ms (average of 100 pings) when plugged in to power, and 56ms when unplugged from power. There were still some long pings (up to 479ms while I was testing)/dropped packets when plugged in, but much less than when unplugged. FWIW, I see the same behavior if I ping something outside my local network, just with more noise since that's subject to latency from my ISP and actual round-trip times.

I'd be very curious if anyone else sees the same behavior. To test, open up a command prompt or powershell window and run:

ping -n 100 192.168.1.1

(replace the 192.168.1.1 with the IP address of your router if it's different, or use 8.8.8.8 to ping Google's DNS servers if you want to test outside your network and/or aren't sure what your router's IP is)

Edit to add: I did test with the power cord plugged into the laptop but not into the wall, and that didn't have any effect compared with no cable, the laptop really needs to be getting wall power to see the improvement (that is, it's not the power cord functioning as an antenna to boost the signal, or at least not just that).

It's not unreasonable that your ping times are higher on battery power. It is common for chipsets to throttle to save power when you have no active traffic.  

[alec7]

While it’s true that the chipset could behave differently on battery/power saving mode, if you think a 56ms average ping time when located 1 foot from the router is “not unreasonable,” then I’m not sure what to tell you. 

I have all the same connectivity problems reported by other people in this thread, and all of them seem to be worse/more frequent when not plugged in. I was just using the ping as an easily reproducible/quantifiable metric of the poor connection. If you have any suggestion on how to prevent the WiFi card/chipset from being throttled, I’m happy to try that as well - literally anything is worth a shot. As you and others have said, the 334 driver from Lenovo seems to help, but I still experience the connection dropouts etc.
