Major Slackware Installation Whine re Networking

So after 20 years I'm taking another whack at getting Slackware up and running. Back then, it was all hardware issues - didn't have the bucks to do anything about it then.

This time, I cannot get Slackware's networking up and running. No other apparent install issues. Umpteen-gazillion attempts - and I don't understand why.

I've gone through the Slack-Docs, the Slack Book, multiple Linux forums, yada yada yada. Even my searches of this site have come up empty (- but I'm now used to my choice of search terms comin' up empty.)

Need help, folks. And I'm now so confused, I no longer no where to start fixing this. Without networking, I have to reboot for every last bit of info - no other boxes available nearby to get online with while I try this.

I have no problem with networking, per se. I have the modem/router set up to lease IPs forever, (for now, to avoid DHCP leasing being a problem). Works fine with all other distros I've tried.

I've tried a static IP. Works fine with all.....

Everything I've tried works with other distros, but NOT Slack. The issue is that I can't find any distros other than Mint 18 that will work acceptably on this box. They all SUCK big-time, (even and especially Mint 19 - which just won't function without crashing) - and this is a Lenovo box on the "famous" Ubuntu Hardware List. (And I'll do without a PC if I have to use Windows.) I've also run every hardware test I can find on this box - it's good.

Can somebody come onboard and help me with this?

If you are interested in some assistance, please provide some information.

When I did the Slackware install, did you do the bit about setting up you network? (I'm assuming you did.)

Are you referring the wired or wireless networking? Please provide information about your network adaptor(s).

If wired, did you use a known-good cable?

What is the output of the command ip addr?

Run, as root, netconfig
and choose to have NetworkManager setup you network "automatically."
That should do it.

If cwizardone's suggestion doesn't work, we would need more info like frankbell mentioned. To start (and I'll reask some questions he did), how are you connecting to the network? Is it wired or wireless? And is your device recognized properly by Slackware? Providing the output of the following three commands could help with diagnosing:

Code:

lspci -k | grep -iA3 net

ifconfig

iwconfig

And you said you did set a static IP, have you tried with a DHCP? Sometimes static can cause issues if there's a conflict on the network or things like the route weren't set up.

Slackware does not work and play well with some Broadcom cards.

If you have a Broadcom card my suggestion would be to check the SlackBuild site and if you cannot find something there that solves the problem use ndiswrapper.

I AM NOT A SLACKWARE EXPERT, merely a novice trying to help.

The version of Slackware that you installed would also be an important bit of information.

Realtek 8139 Ethernet chipsets are also known to be flaky under load. (An old version of the FreeBSD driver had a comment in the source code that the 8139 chipset "brings new meaning to the term 'low-end'." Ouch.)

Sorry -delayed getting back to this, and thanks for the replies...

First, as root, I ran netconfig and set to automatic. (I know I did this in the install, too...)
And then I ran lspci as suggested, with ifconfig and iwconfig, which I'll post below.
Now at startup it connects to Ethernet card and immediately disconnects, starting a loop of connect/disconnect.
Did a Duckduckgo search for "+linux network connects then disconnects immediately" but got nothing helpful (that I could see)

Ok, got it.
Did another search and found my solution here at LQ.

Edited /etc/NetworkManager/conf.d/00-dhcp-client.conf
to
dhcp=dhcpclient

Network is working.
