Packet Loss with RTL8723DE

[venoom27]

Description

I installed both the stable version then tried the dev port LTS version and I am keep getting packet loss to the point that it almost is impossible to use.

Additional context

Add any other context about the problem here that might help the investigation.

I am able to use the same hardware on Arch Linux when I dual boot with no drop out issues. I have also had the same kind of issues with a Macbook pro that I already been working through with support on. https://github.com/pgj/freebsd-wifibox/issues/38

Have you tried to turn it on and off?

• [X] Yes, I have read all the manual pages first!

[pgj]

Hi, thanks for the report! I think the FW_RTW89 option is not needed: this driver can only work with Realtek 8852AE, 8851BE, 8852BE, and 8852CE. Ideally, it should not be loaded but it is worth to check. At the same time, I noticed you had to blacklist the if_rtw88 (FreeBSD) driver from the host -- there is a slight chance that there is interference still and it is worth to check if that is not loaded either. However, based on its man page, it cannot handle this specific model.

What does lsmod say on wifibox console (inside the guest)?

[pgj]

Hrm, looks like Arch Linux has a specific rtw88 driver (a sibling of rtw89) and does not use the one shipped with the vanilla kernel. Realtek's own drivers is known to be unreliable and of low performance. I will port this package and get back with the wifibox-alpine version that you can test.

[pgj]

I have added the rtw88 driver for wifibox-alpine that could be enabled by the FW_RTW88 configuration option. This is version 20230820 that can be found in the dev branch of the pgj/freebsd-wifibox-port repository.

[venoom27]

I installed wifibox-alpine-20230820 with UDS_PASSTHRU, RW_RTW88, KERN_LTS. COMP_XZ, and APP_WPA_SUPPLICANT selected. I am still getting packet lost.

That is sad. Could you please include the uname -a output from the guest? But it looks like we will need to get through the "vanilla Arch Linux as a guest" experiment (as it was sketched in #58) to make it sure that the problem is not due to the underlying virtualization and the host OS.
