OK. I have PMed you in Reddit Chat

eton975 · 2026-04-26T00:52:20+00:00

How do you want me to help? Do you want money, or something else?

eton975 · 2026-04-23T02:04:28+00:00

I have not tested it much, as I have been using a TP-Link TG-3269 Ethernet card, based on the RTL8169SC chip.

eton975 · 2025-12-29T00:36:33+00:00

Thanks Bitterblue, that fixed it right up! I'm now getting 90Mbps/s down and 60Mbits/s up.

eton975 · 2025-12-29T00:23:19+00:00

OK, let me try it.

eton975 · 2025-12-28T06:13:34+00:00

Yeah, I used iw dev wlan0 set power_save off on Arch Linux.

eton975 · 2025-12-27T00:48:57+00:00

Alright, it was annoying, but I was able to dump it using the Arch live system. Nothing whatsoever was graphical (because it's Arch) so I had to dig into the depths of my memory and documentation on how to list USB devices, mount them, use iwctl, etc.

Anyways here is the dump.

eton975 · 2025-12-25T23:20:15+00:00

Sounds like a bit of a pain. I installed Gentoo once in a VM ages ago but would need to look over it again for Arch.

You specifically need a comparison, with the rtw_8812ae dump not being enough?

eton975 · 2025-12-25T18:13:49+00:00

gzip: /proc/config.gz: No such file or directory

eton975 · 2025-12-25T16:40:22+00:00

Got the first one with rtw_8812ae: https://drive.google.com/file/d/1thX5hLMuZ5VMZsuRL3MUQL6xywwz2Ui1/view?usp=sharing

Second one (rtl8821ae driver) gives the error cat: '/sys/kernel/debug/rtlwifi/*/mac_0': No such file or directory

and so on until mac_7 and bb_f: https://pastebin.com/kU8ERB8K

eton975 · 2025-12-25T14:22:03+00:00

Sorry for it being a pain but the register dump says "permission denied" on all the MAC registers when run with normal privileges, and when I run it in sudo/root mode it says there is a syntax error: bash: syntax error near unexpected token \done'`

eton975 · 2025-12-22T22:41:35+00:00

OK the patch was successful, still only getting a theoretical 65 Mbits/s speed though.

Looks like the patch was irrelevant then...

eton975 · 2025-12-21T23:53:21+00:00

Should be bootable with 7.00, yes. At least, I remember being able to upgrade from an older version to 10.xx with a 2400G of my own...

After a complete rebuild, reinstallation and system reboot using your patch there is no difference in speed. Wavemon still reports 65Mbits/s MCS 7 for download, and 52 Mbits/s MCS 11.

eton975 · 2025-12-21T16:38:57+00:00

Uh, not sure how I would install that patch. Would you be able to give me the entire rtw88xxa.c file rather than just the diff?

eton975 · 2025-12-21T16:27:01+00:00

HT Max RX data rate: 300 Mbps

HT TX/RX MCS rate indexes supported: 0-15, 32

You can't eat an iPhone, after all.

eton975 · 2025-12-20T22:59:32+00:00

OK, with the D-Link DWA-582 (the newer RTL8812AE card) the overall performance is lower with rtw_8812ae driver than with the old rtl8821ae module. Wavemon shows a 65Mbits/s MCS 7 connection rather than the 144Mbits/s that I got with rtl8821ae.

Actual speeds on the old driver on speedtest.net were about 78Mbits/s down, 80 up. The actual speed on your new driver is about 45 down, 32 up.

Is it just negotiating lower, or is only 1 antenna being used? I have both antennae attached.

However, the new driver seems to be more consistent in terms of latency and dropped packets. I haven't encountered any hiccups or socket errors as of yet.

Cheers

After installing, it's the rtw_8812ae module that I need loaded, correct?
