New install wifi issues

Hello all. I am trying a first time install on an old Dell. I only have wifi available and Arch isn't showing a wifi connection in "ip link". The wireless card shows up in "lspci -k" but nothing in "ip link" other than the ethernet connection. I have been reading for hours on various sites and can't figure out how to make the connection. Thanks in advance for any advice.

Regards,
Allen

Oh and Welcome to the arch forums.

welcome to arch smile
if your are having trouble connecting to wifi in installation progress you will need to exit chroot if your are already in, then this command "wifi-menu" is freakingly easy, a dialog shows up, you select your SSID and enter password. and its done connecting. you may want to check connection by "ping any_website.com". and exit ping with ctrl+c.
i hope it helped smile happy using arch.

Re: New install wifi issues

Thanks for the replies guys. I don't understand why the wireless shows up in lspci but not getting anything in ip link. So nothing is available in netctl either. I feel as though I have attempted to big of a step in my Linux transition...lol.

Re: New install wifi issues

mazhar, the problem is a driver issue, not a network management issue, so your steps will not help.

Fraggin, Broadcom support is a bit of a mixed bag in linux.  I've actually had very good luck with all broadcom chips, but many of them take just a little bit of user intervention to get up and running.  As a result of this, there tends to be very good documentation, like here:
https://wiki.archlinux.org/index.php/Broadcom_wireless

Please have a look at that page, and use the commands described there to determine your chip id: the hex number after 14e4 if you need help walking through that broadcom page.  I suspect it might be 14e4:4315, but lets confirm that before moving forward.

Re: New install wifi issues

Well its time to drop back and punt until i can just do a wired install. I only have one usb drive with me and it has the Arch .iso on it. Thanks for the help guys. I will post when I get the new drivers installed.

Re: New install wifi issues

Ok so I remember reading that this install is operating in my RAM so I removed my usb drive and downloaded the latest drivers from Broadcom. I was trying to do a manual install but can't seem to mount or access my usb drive from the root installer. I see it in "lsblk" but can't create a directory to mount it to. Perhaps I should just stick to Ubuntu...lmao!

Re: New install wifi issues

Is the current OS on the target machine Ubuntu and if so does it have functioning internet connection under Ubuntu?
Without knowing exactly what commands you tried and what output they generated can not comment on the mount issue.

Re: New install wifi issues

If you are going to "punt" as you say, so be it - but this is likely very easy to get working, and we can help you do just that.  But we can only help if you provide the information requested of you and work with us.

Re: New install wifi issues

Ubuntu is on the computer I am using now. I am trying to do a clean install of Arch on an old Dell laptop. I certainly don't intend on giving up on Arch install. The whole point in doing it was to learn more about the GNU/Linux environment. I have only been at this for a few days so I have lots to learn still. With the install attempt being on another computer I can't simply copy and paste my screen. The only commands to mount the usb drive have been "lsblk" to see if the drive was detected, and then trying "mount" in various forms...lol. The Usb drive is there as "sdc" below the "sdan" tree.

Re: New install wifi issues

Let's try this again: Please (re)read my post #6, follow the guidance in it, and respond to it.  It's clear to me what is wrong, and it is clear what path we need to take to get to a solution.  But if you refuse to walk down that path, nothing can be done.

Re: New install wifi issues

The form of the command you provided above does not have a second parameter.  The second parameter identifies WHERE to mount /dev/sdc.  As such, the mount command looked in /etc/fstab to see if it specifies where to mount the partition.  It didn't, so mount gave up.

Re: New install wifi issues

Trilby by reading your post 6 I downloaded the latest Broadcom drivers. That is what I am attempting to install now off of the usb drive. Not giving it a target to mount to explains my difficulties. Thanks for pointing me in the right directions. I will continue to bang around the terminal tonight and hopefully make some headway or have clearer problems tomorrow...lol. Thanks Trilby and Admin.

Re: New install wifi issues

You still have not provided the numeric id string to be certain which chipset you have.
Would advice against attempting to install the Broadcom drivers directly and build either the required firmware package b43 or broadcom-wl on a temporary install created on the Ubuntu system.

Which ones?  From where?  How are you building them?

Re: New install wifi issues

I downloaded hybrid-v35_64-nodebug-pcoem-6_30_223_271(1).tar.gz from Broadcom's website. I assumed it would compile itself. There goes the good ole "assume" making an ass out of me...lol.

Edit:
Missed you had specified -v so would indicate to me there was no kernel driver in use at the time that command was executed.

Re: New install wifi issues

No where in the wiki page that I linked to is there a suggestion to download drivers directly from broadcom's website.  The wiki contains step by step instructions that *will* work if you follow them.  If you are confused on how to follow the steps, ask specific questions with where your are stuck.  If you refuse to follow the instructions provided, then there's nothing anyone here could do for you.

That wiki page is very well curated, up-to-date, accurate, and (again) will work.

You already have the driver for your card - b43 is built into the kernel.  But you need the firmware, and the firmware "cutter" packages.  One of these is in the AUR, one is in the main repos.

Manually Does suggest doing that although it is covered by a warning against it.
Also the wiki does not mention broadcom-wl does not currently (post kernel 4.2) seem to work with i686 https://bbs.archlinux.org/viewtopic.php?id=215189

Ah, I stand corrected.  It is mentioned ... under a big red warning box tongue
