[+]bardzo wolno dzialajacy internet

: 17 listopada 2019, 13:01
autor: korbielow
Witam!
Mam problem w sieci w pracy bardzo wolno mi dziala internet. Na speedtest wyciaga ledwo 0,2Mb/s.
Jak przelacze na Windows na tym samym laptopie to internet dziala szybko 40 Mb/s.
W mojej sieci domowej ten sam laptop nie ma tych problemow i na debianie dziala
Przypuszczam ze jakis problem ze strownikami lub kernel ?
Mam laptop Dell Latitude e6410.
Czy ktos moze pomoc ?

Porównaj sobie te sterowniki, kernele.
Czy adres IP jest ten sam?

IP sa identyczne zarowno na WIN jak na Debian

Kod: Zaznacz cały

root@debian:/home/rafal# uname -a
Linux debian 4.16.0-1-amd64 #1 SMP Debian 4.16.5-1 (2018-04-29) x86_64 GNU/Linux
Moje wifi to chyba bedzie to 2:00.0 Network controller: Broadcom Inc. and subsidiaries BCM43224 802.11a/b/g/n (rev 01)

Mam wrazenie ze to sie stalo po upgrade debian bo wczesniej mi to dzialalo dobrze.

Kod: Zaznacz cały

Installation

Add a "non-free" component to /etc/apt/sources.list for your Debian version, for example:

# Debian 9 "Stretch"
deb http://deb.debian.org/debian stretch-backports main contrib non-free

# Debian 10 "Buster"
deb http://deb.debian.org/debian buster-backports main contrib non-free
Update the list of available packages. Install the relevant/latest linux-image, linux-headers and broadcom-sta-dkms packages:

# apt-get update
# apt-get install linux-image-$(uname -r|sed 's,[^-]*-[^-]*-,,') linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') broadcom-sta-dkms
This will also install the recommended wireless-tools package. DKMS will build the wl module for your system.

Unload conflicting modules:

# modprobe -r b44 b43 b43legacy ssb brcmsmac bcma
Load the wl module:

# modprobe wl

Jednak bardzo mnie zastanawia czemu w domu mi wfi dzialalo normalnie, a w pracy wolno.
W kazdym badz razie po zastosowaniu tej instrukcji problem znikl.
Swoja droga ten Broadcom BCM4311 bardzo problematyczna karta sieciowa.
