I can't get my internet to work recent Arch ISO install disk (Solved)

Hi my wifi adapter is a Broadcom 802.11 Adapter I am running a Toshiba Satelitte c55-c5270.  tryed the usual stuff modprobe, iwconfig. if up, etc there is no recongition of wifi connection. Can anybody help. I can't post code cause I can't install it. But what I'm telling you is accurate. I need to know if someone can give me a definitive answer as to how to detect my driver or is it a Toshiba problem. I heard that Toshibas have problems with Linux.

No direct solution, but how about a tangential one?  Can you USB tether a phone?  If so, it will show up as a wired connection.  Run dhcpcd to get an address, install the system, and (possibly) install missing firmware.  If nothing else, it will give you the ability to post here from inside your system.  Be careful of carrier data caps -- but you can USB tether a phone while the phone is associated  with wifi.   Nice tool all the way around.

Can you run

lspci -nn -d 14e4:

Then see if you get a listed broadcom device. If so the device id and chipset name will help determine support.

example:
Chipset: BCM4350     
Device ID: 14e4:43a3

What i need to know is if there is a graphical dm install disk I can purchase online from Arch so I can get all the base and a dm installed from a dvd then just go into my windows download the firmware from AUR and just install from pacman with it allready installed from a base dvd, cause the net dvd I would have to temporaily run a 30 foot ethernet cable from my modem in the basement to my living room threw the floor hole to my ethernet jack on my laptop.

laptops are suppose to be mobile!

Getting ethernet or mobile internet should be easy solution as compared to searching something which doesn't exist!

No.  But what on earth would this have to do with getting your wireless working?  An installer with a GUI would be no better than an installer without a GUI if it doesn't have the drivers for your hardware (which you still haven't told us anything about).

Ok sorry bout that I'll post some code that I did that had to copy on pen and paper here it is: I did this and copied it down:

archiso@root#modinfo cfg80211

filename /lib/modules/4.5.1-1-ARCH/kernel/net/wireless/cfg80211.ko.gz
alias.net-pf-16-proto-16-family-nl80211
description: wireless configuration support
license:gpl
author:Johannes Berg
depends: rfkill
intree:Y
vermagic:4.5.1-1-ARCH SMP
preempt mod_unload modversions
parm: ieee80211_regdom:IEEE 80211 regulatory domain code (charp)
parm:cfg80211_disable_40mhz_24ghz:Disable 40 Mhz support in the 2.4 Ghz band (bool)

That's the output of that to me it looks like its hardblocked and I can't seem to unblock it or do i need to install missing firmware i will post the lines talking about internet from journalctl -b after sorry i have to write this stuff down from paper and pen.

Re: I can't get my internet to work recent Arch ISO install disk (Solved)

Thanks for trying to share that information, but please try to answer the questions that have actually been posed to you.  This new information just raises more questions.  I see nothing in that output that suggests anything is hardblocked - I don't even see anything indicating cfg80211 is the relevant module.

You seemed to ignore my question about why you think you need a GUI for any of this.  You don't; but if you were to describe your thinking we might actually be able to help.  Perhaps there is something important you have not yet told us.  Or perhaps you have some misunderstanding of the system that we could help clarify.

Also, you've said in the first post that you have broadcom wireless.  We need to know which broadcom chip.  You've been given the command to check which broadcom chip you have.  You don't even need to copy much information.  We just need the 4 hex digits after the 14e4.  So far all this other stuff you've posted is just tangential and irrelevant: we really just need to know about your wireless hardware first.

The output of `ip a` might also be useful.  If you want to save a lot of typing, as a first pass what I'd really want to see would be just the interface names that you could get from the following command:

ip a | awk '/^[0-9]/ {print $2;}'

Re: I can't get my internet to work recent Arch ISO install disk (Solved)

Ok I was confused now I'm not: This is the output of the driver check:

0.1:00.0 Network controller [0280]: Broadcom [0280]: Broadcom Corperation BCM43142 802.11b/g/n [14e4:4365] (rev 01)

Thats from the first command the second command Trimbly gave me gave me this output:

Re: I can't get my internet to work recent Arch ISO install disk (Solved)

It looks like BCM43142 is not supported by b43 and you will have to try wl. Take a look at the wiki here : https://wiki.archlinux.org/index.php/Br … roadcom-wl

FYI: If you lookup 14e4:4365  here https://wireless.wiki.kernel.org/en/use … f_hardware  you can see where I got this information

Ok thanks for your help guys what I'll do is install the system from a wired connection then download the broadcom-wl package and then get my wifi working. You can mark as solved.

Glad to help. Also you will need to edit the original post and add [Solved] to the front of the title.
