Slow WiFi on RTW89 chip

computer_spider · Today 01:12:49

To begin with my internet had been originally around 500-600 mbps —now I get a measly 13 mbps. I use a wireless connection using Network Manager and wpa as the back-end. The specific chip is RTL8922AE. I am unsure as to what could of caused this change as I have went to try multiple solutions. I had tried disabling power-save mode via /etc/modprobe.d/rtw.conf as well as configurations to network manager. I am using the 5 GHZ channel as well. To further note, I run a dual boot system with Windows and it has no issues with WiFi speeds, and this dual boot has been active for half a year without issue. Further on, I have downloaded RTW89 drives from another similar post to see if that would help fix the issue: https://github.com/morrownr/rtw89/. I also tried using linux-lts to see if it had been related, but it does not seem to be. Afterwards I saw no improvement. If possible could anyone help as I am entirely lost after trying numerous fixes to no avail. Also, I apologize as I am unsure what logs to post along with this as nothing seems unusual.

I run a dual boot system with Windows

3rd link below. Mandatory.
Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

rtw89_pci.disable_aspm_l1=y rtw89_pci.disable_aspm_l1ss=y rtw89_core.disable_ps_mode=y

But also

lsmod | grep rtw

to make sure this isn't handled by rtw88

Ultimately please post your complete system journal for the boot:

sudo journalctl -b | nc termbin.com 9999

Behavior sounds like you're on 802.11a instead of 802.11n (or ac/x)

Thank you again for helping!

3rd link below. Mandatory. Disable it (it's NOT the BIOS setting!) and reboot windows and linux twice for voodo reasons.

Unfortunately, this was something I had already tried. I checked once again, but fast boot was still disabled. I also have hibernation turned off as that caused other issues at some point.

But also
lsmod | grep rtw
to make sure this isn't handled by rtw88

It does not seem to be the case. Here is the output as confirmation:

Ultimately please post your complete system journal for the boot:
sudo journalctl -b | nc termbin.com 9999

As per requested; however, I was unable to use termbin. I doubt it relates to this issue but nevertheless I mention it. I even tested on my laptop and seem to be unable to upload to termbin. I hope pastebin is acceptable.

I am unsure how to test this or if this is related, but seemingly this issue is not isolated to my computer. I thought this issue was bizarre due to no updates being made on my computer when this issue began recently, last few days. It seems others are experiencing the same issue, that is Xfinity (Comcast). Unfortunately, I do not have ease of access to manipulate Xfinity settings. To further add, my laptop, that is also Linux, has slow WiFi as well now, despite being able to reach higher download speeds on other networks. I am unsure if this issue can be resolved via these forums. I apologize if this is now the inappropriate place to post this issue.
