Hi. looking to buy a 17" amd/intel multi core/thread system. I'd like
to be able to add mem/hdd, as well as have lan port.

I can deal with an olde/refurbished system.

I'm hoping that the list can tell me what you might have, so I can use
this as a starting point. Newer systems appear to possibly run into
wifi driver issues.

thanks

I have a HP 17" and I replaced the wifi with an intel  ax200 ($20
upgrade) as the half-assed one did not work reliably.

Ie the wifi would work for a few hours/days and then stop working and
require a down/up to get it working again.

Most of all of the laptops will likely have the half-assed wifi
adaptor and just plan on making sure the laptop one has a removable
wifi that you can replace. This is the 2nd 17" laptop I have had to
replace the wifi in (this is a 2023 HP laptop, the other was a 2016
Acer laptop).

Just anecdotally, I've been running Fedora on Lenovo X1s since 2015, 2
work-issued devices, and this latest one a personal machine, and the wifi
has been rock solid.

The current device is:

root@fedora:~# lspci | grep -i wi-fi
00:14.3 Network controller: Intel Corporation Wi-Fi 6 AX201 (rev 20)
root@fedora:~# dmidecode | grep -i x1
Version: ThinkPad X1 Carbon Gen 9
SKU Number: LENOVO_MT_20XW_BU_Think_FM_ThinkPad X1 Carbon Gen 9
Family: ThinkPad X1 Carbon Gen 9

The previous laptops would have most likely been:

2015: 2nd or 3rd Gen.
2019: 7th Gen.

Obviously none of these match your size requirements but just in terms of
chipset reliability... figured it might be helpful.

Hi Roger.  If I understand your reply. You're saying you purchased a wifi
adapter  and I guess got a USB wifi adapter??  Am I missing something?

I'm  looking at the HP 17t-cn300 17.3"  370$

Are you familiar with it?  Oh, and where can I find information on a wifi
adapter?

thanks!

No, you open it up and replace the internal wifi module.  Probably pcie, 
but you need to see what kind of socket it is.

The specs say "Realtek Wi-Fi 6 (2x2) and Bluetooth® 5.3 wireless card". 
Maybe you can ask them for more specific chipset info if you're concerned.

hmmm..  I would have thought most parts would have been soldered..  on the
mobo!!!

I'll check with hp tech support.

or  at the least  I could try a usb  wifi adapter.  or would that
potentially conflict?

You can do that.  There's no conflict.

[Roger Heflin]

The Wifi adaptor is almost always an m2 adaptor (M2 PCIe slot) inside
the laptop and is replaceable.

Will's referenced laptop is I think a corporate laptop and the
expensive corporate models typically come with the intel wifi adaptor.

It it replaceable similar to ram, you might have to take off the
entire back cover to replace it, but on at least some laptops that
also has to come off for ram and hd's.

You should be able to find videos on replacing it for a few models,
and you may be able to find a replacement video for the model you
want.

The usb wifi adaptors typically have worse driver and reliability
issues that the original crappy internal ones.

Hi Roger!

It occurred to me that years ago, I had to experiment with getting
centos+wireless to work on some Dell servers. Had to get a bunch of
Usb wifi modules to work. I'm wondering if these modules would still
work?

thoughts?

thanks

Years ago the only ones I found with drivers in linux were N300 (even
slot at the time) usb devices.

You would have to check the state of usb wireless now and guess if
they are reliable or not.

Overall replacing the card takes 10-15 minutes.  There is one screw,
the card in the slot and up to 2 tiny antenna connectors, at most if
your laptop has only one antenna connected you would need to get a 2nd
antenna and put it someplace inside the laptop.

I have done the usb wifi, and after having done it the card
replacement is MUCH faster and much more reliable and the Intel AX200
cards are widely available for $20.

ps.

In some of my research/youtube, HP (others??) might have a blacklist,
preventing other 3rd party wifi chipsets to run. Some of the
information appears to be a few years old. Is this still a potential
issue?

[Roger Heflin]

I would be surprised if any of the laptop vendors did that.   There is
no profit motive for them to prevent other chipsets from working and
it takes extra code.

Now it would be possible that some wifi pcie cards do not work with
the laptop chipset/slot wiring so you might be best picking an older
wifi (like the ax200 instead of the ax201).    ax200 have worked on 2
machines I have from 2016 up to 2023.  But I do think someone
attempted to put a ax201 in their laptop and it did not work.   I can
see someone claiming/theorizing that was a blacklist with no proof of
an actual blacklist, and the most likely reason is a pci-e bug between
the 2 cards.

Years ago one of the early 10gbit intel pcix card's did not work with
intel chipset but did work with an AMD cpu chipset.    No reason for
it to not work but likely there was a chipset bug on the intel
motherboard that did not work right with some feature the pcix card
needed.

It's definitely something some have done, probably to "limit support
costs" (or really, limit customer choices in replacement parts to
marked-up vendor hardware).  I know for example that Thinkpads at one
point would only activate Thinkpad wifi cards, based on PCI ID (not sure
if they still do this).

There have been real cases of a laptop BIOS whitelisting certain wifi 
cards.  It was documented and people even modified the BIOS firmware to 
allow the card they wanted to use.

A quick search got this as the top result:

Not to mention that having a USB dongle sticking out on a laptop is
prone to damage or getting lost.  I'd say it's worth the effort if you
can get an internal one going.

I had a usb one for a while.  It was velcroed onto the back and the
usb ports and cable started giving me trouble after a few months.

So by far the simplest/best/cheapest solution is to replace the internal card.

For IBM it was more likely they whitelisted wifi adaptors than
blacklisted them, and likey it was because IBM sold their own branded
ones and wanted to force you to use their high dollar branded one.
Making money as an OEM is always about markup on the add-on parts and
convincing the customers that the OEM's magic parts are somehow better
than the exact same non-oem part that costs a lot less.   I don't
believe any of the current laptop makers are really doing that
anymore.

Hi.

One of the HP sales reps, seems to have indicated that the internal
wifi for the "hp  17z-cp300" laptop would be --> "M91238-005". Is this
supported by Ubuntu/kernel?

How can I see that it is (if it is)?

thanks

The Linux Hardware Database https://linux-hardware.org should provide
details of the WiFi in your laptop model and a either "detected" or
"works".
Vendors often offer optional WiFi internal WiFi cards for large orders.
Newer
Intel systems moved some network functions into the CPU chipset
CNVi WiFi slot https://en.wikipedia.org/wiki/CNVi and the WiFI is
a CRF (Companion RF) module.

There are WiFi cards with 2 antenna connectors and others with only 1.

See:
https://www.thinkpenguin.com/gnu-linux/mini-pci-mini-pci-e-mini-pci-e-half-h...
for pictures of different WiFi cards.

Note that the WiFi adaptor I replaced was found by the native kernel
(no add on driver) and "works" most of the time.

Vendor certifications of supported hardware (even with high end
enterprise vendors) often barely test the device at all so are not
with much at all.

I have had enterprise vendors certify hardware to work with a given OS
that had driver/hardware interactions that had a MTBF under reasonable
OS load of under a month on one machine.   Works for wifi is the OS
found the driver and put an IP address on it and viewed a couple of
websites and tells you zero about if it is reliable and does not fail
several times a day.

You likely need to determine what the underlying hardware is.

[bruce]

right.  but  all I'm doing now is to be prepared until I get the box.

thanks

Amazon, etc. sell lots of cheap junk, so it is important to choose an
established
vendor that has good linux support -- see: <
https://github.com/morrownr/USB-WiFi%3E
for a list of "plug-and-play" on linux USB WiFi adapters

There are some very small wifi adapters that work well if the laptop has
line-of-sight to an AP.   The one I use is 2.4 GHz only, as is the one shown
in the plug-and-play list.
