Hi, Guys/Gals,

OK, I installed RHEL 7.5 on my i7 laptop, when it came to the configuration page before the actual install process begins, I went into "Hostname/Networking", saw my SSID, picked it up from the list, entered my password, but it could not/did not connect. Is there an additional package (s) that needs to be installed to recognize the card? Without the internet I obviously can't do much, no downloading new s/w, no update, no connecting to Red Hat subscription site, etc.

Can someone please tell me how to configure my wireless NIC?

Many thanks in advance!

Read the "Question Guidelines" link in my posting signature. Saying 'i7 laptop', tells us absolutely NOTHING about your hardware, what kind of wifi card/chipset you have, desktop environment you're using, network manager/wicked, etc. How do you think we'll be able to tell you what to look at without knowing?

Since you allude to having a RH subscription (by saying you can't connect to the RH subscription site), have you called Red Hat for the support you're paying for? Are you able to connect via wired connection? You also realize that RHEL 7 is *NOT* a good choice for a laptop, right? RHEL is designed for servers, which don't normally have 'consumer' things (like wifi, bluetooth, sound, and most of the time not even keyboards/mice/screens). Support for such things is often hit or miss.

Thanks for your reply. When I issue the command "ip a", below is what I get

3: wlp3s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 24:77:03:2e:21:28 brd ff:ff:ff:ff:ff:ff

Is there another command to tell us more about the wireless NIC?

How about actually telling us what brand/model of laptop??? Maybe looking in your owners manual, or online at the docs? And how about answering/acknowledging the other things in my previous post????

As said clearly before:

• What kind of wifi card/chipset you have
• What desktop environment you're using
• Are you using network manager/wicked/what to connect?
• Have you called Red Hat for the support you're paying for?
• Are you able to connect via wired connection?

Manufacturer: Dell Inc.
Product Name: Latitude E6420
Version: 01

- What kind of wifi card/chipset you have?
Well, when I issue the command "lspci", it doesn't work. The command "ifconfig" doesn't work. What else is there? Maybe you throw in some suggestions.

- What desktop environment you're using?
Only CLI

- Are you using network manager/wicked/what to connect?
NetworkManager is installed, but when I try to bring wlp3s0 (the wireless NIC) up, it doesn't do anything


- Have you called Red Hat for the support you're paying for?
I actually don't have a paid subscription. I downloaded my RHEL 7.5 from https://developers.redhat.com/

- Are you able to connect via wired connection?
I don't have a CAT5 cable right now to try. I'm doing all of this from my bedroom

- You also realize that RHEL 7 is *NOT* a good choice for a laptop, right?
Yes, I know that, but I have to make this work, as I'm trying to prepare for a job interview at a RHEL company

Might help if you were more specific about what "doesn't work" means. Are you running those commands as root? Have you tried: iwlist scan

And this is the very thing I asked at first. You could have just answered "Dell Latitude E6420". It's probably on a sticker on your system too, why run any commands?
Where, exactly, are you getting these commands? And again, why can't you look on Dell's website to find this out? Or in the owners manual? It specifically tells you what kind of card you got at purchase time. Putting your brand/model into Google along with 'wifi linux', yields lots, including numerous commands. Have you tried any of that yet? Try running things like
...which will *PROBABLY* tell you that you have a Broadcomm chipset. Again, saying "it doesn't work", tells us nothing.
Ok, so what command(s) are you using to try to connect??? Again, we need more than "doesn't do anything"
Well, you may actually have to get up and move around for the time being, to get what you need downloaded
This is incredibly ironic; you do realize that you are essentially admitting you're not qualified for this position right? Because:

• Aside from a few things, ANY version of Linux is much like any other. Know one, and you know them all.
• You could load Fedora and still get prepared for an RHEL job...because you do realize that Fedora is the bleeding edge of RHEL, right?
• You do realize that CentOS is practically IDENTICAL to RHEL, but totally free, right? If you're doing self-support, getting that developers edition is pointless.
• You have done no research about your problem, and it's been difficult to get you to provide even basic information when asked.

Since you're using a broadcomm chipset (probably), there may be b43 packages available, which you need to install. If you're applying for a job and an RHEL company, a good thing to learn would be how to use yum to search for packages; the man page can tell you.

And there are pages of docs on how to configure Broadcomm on RHEL/CentOS:

Might help if you were more specific about what "doesn't work" means.
- Well, 1- it means I can't get on the internet 2- if you look at the output of "ip a", clearly it says wlp3s0 is DOWN
3: wlp3s0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 24:77:03:2e:21:28 brd ff:ff:ff:ff:ff:ff


Are you running those commands as root?
- Yes

Have you tried: iwlist scan?
- It appears to me in RHEL 7.5, they've done away with a whole bunch of traditional networking commands. Although my installation was completed w/o an error, but I don't have ifconfig, lspci, iwlist!

Again, you say **ZERO** about where you got this; and again, this is the Broadcom chipset.
Right; we understand it's DOWN. We're asking (repeatedly), what you're doing and what the messages are. You're not answering. Things like "I'm typing in xxxxx as root, and am seeing YYYYY."
Right; again, RHEL **DOES NOT** have those commands, because RHEL isn't a good choice for a laptop. You can install them, but since you're going to work for an RHEL company, you should know those commands have been deprecated, and are no longer used. If you're applying for a job, you should already know the replacement commands for the ones you mentioned. LSPCI has to be installed separately on RHEL 7.

Again, have you done ANY research on your own problem?? Putting "ifconfig rhel7", "iwlist rhel7" or "lspci rhel7" into Google tells you what's going on with those commands. If you are truly going for an RHEL related job, then you should know you could load Fedora in 30 minutes, have EVERYTHING working, and begin learning.

Well, as i said, I haven't installed the GUI and I'm only on the command line. So, I can't try to actually go to a website and see what the error is. But, when I try CLI commands that require internet connectivity, i.e. "# nslookup yahoo.com", it just chokes. Actually in the case of "nslookup", it returns command not found. I'm sure FTP or nothing else works either. And that my friend is what I mean when I say it doesn't work. IT JUST DOESN'T WORK!

Yes, right...we understand that. But what you CAN DO is what we've been asking, and that is to ***POST THE MESSAGES HERE*** Do you not understand that????? Just saying "doesn't work", tells us absolutely nothing.
I am not your friend. You have been asked, repeatedly now, to post the actual commands you're typing in, and to post what the RESULTS of typing those commands in. You have not, and apparently will not. You have been given suggestions to search for/load b43 packages for your broadcom card, which we even had to look up for you. You have either not done so, or you won't. You have asked about commands and were told where to look for information about them...again, you haven't/won't. There is NOTHING we can do to help you unless you answer questions and cooperate.

AGAIN: Load Fedora; there is ZERO need for RHEL to learn with. And if you are going to apply for a job using RHEL, and can't do basic research, know what commands work/don't work, or how to clearly communicate a problem, do you honestly think you're qualified for it?

Either provide details and/or try the things suggested or load another distro. Past that, it seems there is little anyone here can do to help you.

I honestly don't think you know anything more than I, if not less. A true guru would list a set of commands to try. You haven't suggested a single command, I came up with all of it myself. And, you don't seem to belong to a public forum, you are short tempered, you are NOT nice, courteous, or professional. And again, you haven't added a thing to this discussion. And it is not your business how or why I want to get a job, I did NOT ask you about career advise. I only asked you a simple question which you obviously have no idea how to solve or even how to approach. ALL THE BEST!

...and without knowing what you've done, what do you think we should suggest? Start typing in random commands?
...except for the ones in post #7, #9, etc., you're right...done nothing for you. I looked up your brand/model #, since when you were asked what kind of system it was, you had to run some command. Instead of, apparently, LOOKING at the system to see the Dell label on it.

You were told to look for the package for providing the lspci command, and you didn't. You were told to look for the replacement commands for iwlist and ifconfig, and you didn't. Can't force to you to pay attention or run commands, or show effort, that's something you have to do.
Except tell you what you're missing and how to make it work, but you apparently can't understand the answer. And I DO NOT have to hold your hand and be nice to you...if you're afraid of the mean people online, you should try to go re-read all the stuff you've posted. When people are taking time out of their day to ask you "what are you typing in and what are the results?", and you IGNORE the questions and run random things, and just say "it doesn't work!" over and over, do you think folks will get frustrated???

You're not paying for support; when you do, they HAVE TO BE NICE to you, because it's their job. But you're not. Grow up. You've been using Linux for EIGHT YEARS...at what point are you going to be able to do some research on your own?
Sorry, I told you EXACTLY what you need to do, but you won't follow through or answer questions. You keep parroting back "it doesn't work!", and think that tells us something new. If you're applying for a job using RHEL, and you can't follow VERY basic instructions, you are not qualified. Sorry if it's harsh, but it's true. You even seem to lack the motivation needed to get up out of your bedroom to use a wired connection to solve your problem, based on your earlier post.

Again, since you've ignored it many times:

• Read the man page on yum; it will tell you how to search for a package
• Search for the b43 packages and install the missing ones
• Reboot and look for the b43 module and see if it's installed
• Install the missing packages for iwlist (again TRY LOOKING SOMETHING UP YOURSELF) so you can connect.
• Connect

If any of those steps are too hard or unclear, you're not qualified for the job you're applying for.

@OP, Try to imagine that you are us. We help many people at no charge. Our collective experience is quite valuable. We don't appreciate our words being ignored. We also don't appreciate people coming here and essentially asking us to use a search engine for them.

You received some rough treatment because you're ignoring our requests for useful information. If you stop ignoring our requests, and provide the information we are asking, we'll help you. But if you can't get a wireless connection, I seriously doubt you know more than TB0ne.

I think you are from the Japanese culture. You're not accustomed to what you might consider rudeness coming from American culture. Well, we consider it just as rude when you ignore our words, refuse to follow our advice so we can offer you assistance, and continue with you're vague and meaningless inquiries.

So, we're just giving you a taste of your own medicine. Now, RHEL uses network-manager to make connections. Try 'man nmcli'. You're going to need that program anyway for many things. You might as well learn it now.
