Poor WiFi Performace - HP 15-bs013dx Laptop - Realtek RTL8723DE

Hey I just installed arch on my previously windows laptop (never had an issue on windows WiFi speeds) and have been having pretty bad WiFi performance on WiFi in particular, Ethernet  has no issues whatsoever. As mentioned in the title the laptop is an HP Notebook 15-bs013dx with a Realtek RTL8723DE Network controller. The WiFi sometimes has short bursts where it's actually usable but most of the time whenever I try to navigate to a website or download something using curl wget or on rare occasion pacman it just times out making the device kind of unusable for internet tasks unless tethered to the router.

I've tried changing the antenna selection but it doesn't seem to be helping much although it claimed to have greater signal strength when running iwlist scan after I changed it. Went from like 24/70 (not sure if that was the number but it was low) to 70/70 although performance doesn't seem to have changed.

Ping test of 10 packets to google.com
Ethernet:

 --- google.com ping statistics ---
10 packets transmitted, 10 received, 0% packet loss, time 9015ms
rtt min/avg/max/mdev = 16.645/20.636/25.803/3.551 ms 

Wifi:

 ping: google.com: Temporary failure in name resolution
--- google.com ping statistics ---
10 packets transmitted, 1 received, 90% packet loss, time 13906ms
rtt min/avg/max/mdev = 319.908/319.908/319.908/0.000 ms
--- google.com ping statistics ---
10 packets transmitted, 2 received, 80% packet loss, time 32708ms
rtt min/avg/max/mdev = 82.906/96.813/110.720/13.907 ms

And that's me literally sitting in front of the router, earlier today the best I got was like 50% packet loss.

Sorry if these details are too vauge, if I can provide any more details just let me know (pretty new so if you could tell me how to provide said details that would be great).

going by that the kernel doesnt have the correct driver for your hardware, try this driver from the aur: https://aur.archlinux.org/packages/rtl8723de-dkms-git/

Re: Poor WiFi Performace - HP 15-bs013dx Laptop - Realtek RTL8723DE

grep -ir RTL8723DE /usr/lib/modules/5.14.12-arch1-1/build/drivers/net/wireless/*

returns nothing

It is an rtw88 driver with a slightly different name.

pacman -Ql linux | grep 8723de
linux /usr/lib/modules/5.14.16-arch1-1/kernel/drivers/net/wireless/realtek/rtw88/rtw88_8723de.ko.zst

The dkms driver has been abandoned and will only work with linux 5.10 (currently in the linux-lts package) It could be working a bit better, though.

Currently running the linux-lts kernel and it appears at some point In my testing I already installed that driver, despite this my performance is still not great. Unfortunate they stopped development on the driver for whatever reason.

realtek often only does very few codes dump with questionable maintainability. Then it is on the community and maybe the card manufacturers to update the driver. Since there is now an alternative driver in the kernel which in theory is better structured there is not much incentive to keep the rotting drivers going.
