Низкая скорость у WIFI RTL8723BU в Linux

Здравствуйте дорогие форумчане!

С первого дня покупки ноута сразу поставил Archlinux и пару лет ничего не подозревая работал думая, что 11 мегабит это максимальная скорость для этой железяки. Адаптер
Bus 001 Device 003: ID 0bda:b720 Realtek Semiconductor Corp. RTL8723BU 802.11b/g/n WLAN Adapter
Пару дней назад нужно было поработать в windows установил на внешний usb hdd win10 скачивая с торрента удивился скорости 4 мегабайта это 32 мегабита.
Ноут ближе к роутеру стационарный ПК дальше от роутера и у него скорость 70 мегабит, wifi в нем тоже ноутбучный, в сущности в стационарном также ноутбучное железо, мини пк книжка по размеру. Роутер древний микротик но скорость по wifi отдает нормально, на частоте 2.4.
В том-же самом расположении ноут принемает скорость в archlinux 11 мегабит в винде 32 мегабита, подскажите пожалуйста что можно попробовать? Как наладить железку на оптимальную работу?

Сервера в спидтесте одинаковые оба теста на ноутбуке в разных осях.

вот тут почитайте,там правда про RTL8723AU но принцип тот-же.
про blacklist rtl8xxxu в конце.
Ощущение такое что это прям решение квеста
Регион законы , разные параметры могут быть. Настройки и режим, драйвер.
Можно https://aur.archlinux.org/packages/rtl8723bu-git-dkms/
еще попробовать вместо стандартного драйвера

На 2 пк тотже archlinux с дефолтными настройками и работает хорошо. Значит драйвер?

Подскажите пожалуйста как узнать имя модуля?

В man не могу понять :(


ИМЯ
modinfo - Показать информацию о модуле ядра Linux
ОБЗОР

modinfo [ -0 ] [ -F поле ] [ -k ядро ] [имя модуля | имя файла ...]

modinfo -V

modinfo -h


Ядро /lib/modules/5.14.16-arch1-1
BPOH
как узнать имя модуля?
  lspci -v
например

вот нашел Wifi карточка Rtl8723bu...
еще узнать какой драйвер используется,,если плохой=заблеклистить.

я про это https://wiki.archlinux.org/title/Network_configuration/Wireless#Respecting_the_regulatory_domain

на винде могли не поставить регион а на арче стоит, мощность карточки ограничивается в соответствии с законом региона

еще узнать какой драйвер используется,,

lspci -v в выводе раз 10 перечитал не могу увидеть сетевую карту, может быть такое что она тут неотображается?

Разьве может быть такое? На одном пк linux есть ограничения по региону а на втором нет? хотя устанавливал все одинаково.
