18.04 broadcom wifi very slow. I tried the "chili555 method" already!

[datagueule]

Hi all,

I need to retype everything as my wifi stopped haha
anyway

My wifi is very slow...

I tried several stuff:

1)Disable 802.11n
I typed

sudo rmmod iwlwif
 sudo modprobe iwlwifi 11n_disable=1

got this:

rmmod: ERROR: Module iwlwif is not currently loaded

I guess this line is for intel, but I have broadcom. is it why I get an error?

2)fixing a bug in debian avahi
with this:

sudo gedit /etc/nsswitch.conf

and changed a line to this:

hosts:          files dns

but it didn't work so I undid the change

3)"the chili method"
I ran all lines

 sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/*

no output but no error either

sudo iw reg get

I got this

global
country CA: DFS-FCC
    (2402 - 2472 @ 40), (N/A, 30), (N/A)
    (5150 - 5250 @ 80), (N/A, 23), (N/A), NO-OUTDOOR, AUTO-BW
    (5250 - 5350 @ 80), (N/A, 24), (0 ms), DFS, AUTO-BW
    (5470 - 5600 @ 80), (N/A, 24), (0 ms), DFS
    (5650 - 5730 @ 80), (N/A, 24), (0 ms), DFS
    (5735 - 5835 @ 80), (N/A, 30), (N/A)

so I guess I m ok, it s set to canada

I also went to the settings of my wifi and disabled IPv6.

sometimes my wifi is fine for a dozen of seconds, then get super slow. It s pretty unstable
is it something to do with

bcmwl-kernel-source

?
Is there another driver I need to install?

Any ideas? thanks for your help!

That's correct but don't feel bad, this and most other fora are littered with new users who undertake changes without any regard to what wireless chip they have. They install Broadcom drivers and are disaapointed when their Realtek device won't work, they invoke Intel parameters for Atheros devices, etc.

To all you searchers out there, it is useless to undertake fixes without knowing if it applies to your exact device. Don't go to the parts store to buy a windshield wiper for your Ford if you actually own a Honda. It won't fit and it won't work.

The title of your thread suggests that your wireless is slow. The body says:

my wifi stopped

So which is it? Does it stop and start or is it slow or is it both?

Did you try ALL of the chili555 methods?

First, check the settings in the router. WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP. Second, if your router is capable of N speeds, you may have better connectivity with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz, although it is likely to affect N speeds. I also have better luck with a fixed channel, either 1, 6 or 11, rather than automatic channel selection. Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router.

Do you have a dual band 2.4 gHz and 5 gHz router? Are both segments named the same? Does your Broadcom wireless hop back and forth among the bands looking for a better connection, much like my ex-girlfriend? If so, I suggest that you rename the segments in the administration pages of the router, something like myroutert2.4 and myrouter5.

Hi Chili,

thanks for the reply!
I unfortunately don't have access to the router because it's upstairs with my landlords and they fled the virus.
Also, my thinkpad laptop have a good connection, without the need to do anything to the rooter, so isn't it a problem with this desktop and not the rooter?

My connection stopped once so I lost my text that's why I wrote "wifi stopped", but else it's just slow. sometimes it can load a 720 p youtube video then the moment after not even with 360p. It's not only with youtube, in general other page load slowly and when I download a package it s very slow too

We don't know yet. Does the Thinkpad have the exact same wireless device and use bcmwl-kernel-source? Some Linux driver and hardware combinations work well with default router settings and some do not.

Let's see if the logs have any further clues. Please run and post:

Wow! That is one unhappy driver!

We need just a few more data points:

uname -r 
lsb_release -d
sudo dpkg -s bcmwl-kernel-source | grep Version

I suspect that there is a mismatch here.

[datagueule]

Wow! That is one unhappy driver!

hahaha is it ? how do you see that ? all the error that were listed ?

5.3.0-45-generic

Description:    Ubuntu 18.04.4 LTS

Version: 6.30.223.271+bdcom-0ubuntu5~18.04.1

mmh is it something to do with the 18.04.01 version

[datagueule]

Anybody has an idea how I could resolve this?
thank you!

I regret that I haven't any other suggestions.

As far as I can tell, you have the correct driver and the correct version of that driver matching your kernel version. A Google search of the significant errors, 'ERROR @wl_cfg80211_get_station : ' yields nothing useful.

You might try booting into an earlier kernel version than -45 at the GRUB menu to see if the wireless works.

You might try a live session for Ubuntu 19.10 and see if the later Ubuntu version helps. Frankly, I doubt it.

Finally, you might buy an inexpensive USB wireless and wait to see if a later kernel version and driver version fixes the issue.

I'm sorry that I have no better recommendation.

[datagueule]

thanks for your help!!

do you have any idea if I can contact one of the developper from ubuntu if they have an answer? the 18.04 is not that young, I mean it s surprising my wifi driver is not adapted
thank you
