well I need to improve my tutorial then....so my fault not yours.

I would suggest post two is for people trying out the live cd

OK so lets discover your actual hardware please.

Can you copy and paste just your wireless stuff from this command please?

Code: Select all

lspci -vvv
because I have a tower, to see mine I have to do something different....which won't help you but I show regardless

Code: Select all

lsusb | grep WLAN
Bus 001 Device 004: ID 0bda:8172 Realtek Semiconductor Corp. RTL8191SU 802.11n WLAN Adapter

I have a tower as well, so I am not sure if this is what you want

Not sure is this will help

lspci -vvv should have given you the device number so lets try it another way

Code: Select all

lspci -nn -d 14e4:

Yours should be the middle one
14e4:4328 partially BCM4321 a/b/g/n N (r2) wl
14e4:4329 partially BCM4321 b/g/n N (r1) wl
14e4:432a not tested BCM4321 a/n N wl
However I least we know it can do b/g/n especially the n.

Leaping ahead can you now on Nemesis show the full list of

Code: Select all

lsmod
I am interested in whether you have wl loaded and or another wireless module interfering with it.
If we find one, we can blacklist it or them.

OK as forecast your is the middle one I posted about in terms of device number.

Now I don't have your hardware but I am now going to split up your kernel modules and others can jump in if I make errors

so there are only 2 there that could be causing interference

forcedeth which appears to be your ethernet module and ipv6

########################################################################

Using root powers manually unload forcedeth and see if there is any improvement

Code: Select all

sudo rmmod forcedeth
If no improvement then without rebooting see if you can remove the ipv6 by another sudo command and report please.

Only if there is an improvement would I suggest you look at persistence by adding some lines to a modprobe bootup file that will blacklist one or more modules.
As I have only a dongle I am not sure what will happen

Tried it, and still "page not found"
Forcedeth closed no problem but ipv6 would not, I was told that it is "in use"

Post#23 by aus9 » 27 Dec 2015, 13:23

excellent we are getting there a bit at time.

I have no such module loaded either with ethernet or usb wifi dongle so its time to try persistence over reboot.

If you have not already done so, reboot Nemesis with a changes cheatcode.
my changes folder is at same level as my porteus folder.

now use root powers to go edit the following file....before doing so make a backup somewhere outside your internal structure
eg I have porteus on /mnt/sda3 so copy this file to /mnt/sda3 ....change yours to suit
/etc/modprobe.d/broadcom_blacklist.conf
Now use root powers to edit that file ....you notice one line per blacklist so add 2 new lines

blacklist forcedeth
blacklist ipv6

##########################

Now this won't work if your router only does ipv6 but as you have not said anything we will soon find out eh?

full reboot to test please and report

Post#24 by aus9 » 27 Dec 2015, 13:43

I am going to bed soon so thought I might post another way in case kernel module for ipv6 can't be blacklisted

http://superuser.com/questions/575684/h ... e-in-linux
so lets pretend you booted and still found ipv6 but no forcedeth then remove ipv6 blacklist line and try this instead

Code: Select all

sudo leafpad
open /proc/sys/net/ipv6/conf/default/disable_ipv6

edit file from 0 to make it a 1 and save file and exit, reboot to test

Hi
wl "should" be the right driver but have you already tried the alternatives?
francois gave the link to fanthoms tutorial..

However,..just another idea..
Can you reach a web page directly via its IP-address?
(this will bypass your routers DNS),
try to reach Google = http://74.125.224.72/
type the address into your Browsers address field.

some tests:
guest@localhost:~$ ping "your Gateway address here"
you should get an answer,if yes, try to ping googles DNS server

guest@localhost:~$ ping 8.8.8.8
do you get an answer?

btw.
to disable the ipv6 stack temporary:
root@localhost:~# echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6

good luck knixter..and aus9..

beny
Hopefully he is on Nemesis LXDE so no Konsole and there should be gap in commands but I will translate them for OP

Code: Select all

sudo su
pman -S adwaita-icon-theme  (to see radio buttons on nm applet)
ifconfig eth0 down
ifconfig eth1 down
ifconfig (should now show only lo stuff)
ifconfig eth1 up
ifconfig  (should show lo and wlan or lo and eth1 with wireless stuff
if stil only lo then next command to try is ifconfig eth0 up

Now look at network applet and hover over it, does it say some kind of ethernet or wlan?

##################################

Leaping ahead if no change.....RH click network applet and choose disable wireless and then re-enable wireless and re-test

Tried the above, no difference
Link to screenshot, notice there is traffic but I cannot get any page to load
I am not using Nemesis, I could not figure out how to install to my hard drive
