A riddle ...
My cable modem wifi gateway is 192.168.1.1 My Buffalo 600N gateway is 192.168.11.1
On my Acer I can see access points from both wifis.
On my HP I can only see access points on the cable modem gateway.

Hmm, not a network expert but why different subnets? With wifi, the network manager is assigning the subnet so it can "see" any network. If you HP is wired or maybe some Wifi restriction in place, maybe it can't see the second subnet? I'm just guessing here.

If you need two subnets, use a wider subnet mask to allow connection across the both networks.

You could probably just assign the 600N an IP 192.168.1.2 - again I'm pretty much beginner in the world of networks.

@here when I had two routers I used 255.255.254.0 as a subnet mask and then 192.168.1.1 and 192.168.0.1 for the routers. Since then I added a second Asus router and meshed with my primary. Works better than two subnets - devices only see one IP address and don't have to switch over.

I know next to nothing abut networking. However, when I first installed Neon on this HP it had both Secureboot and EFI active and when the wifi was working I could see AP's from both routers.

I was able for the small amount of time the wifi worked, to reserve 192.168.1.100 and assign it to my HP's wifi MAC address regardless of who is logged into my net or when. That way I could assign that local address to my he-ipv6 service, to emulate native IPv6 protocol. It worked and my browser automatically tries to load the IPv6 page first and rolled over to IPv4 within 1 second if it wasn't successful. That is, when my HP could see my Buffalo. WIth Secureboot disabled I am not able to see the Buffalo's AP's but that may be a coincidence and not a cause.

But, it's just another problem and I'm having fun solving them! I took my cable modem box apart and found a sticker with the name and password underneath so I am going to experiment with it and see how I can mess it up.

And what could possibly go wrong with that!

[oshunluvr]

Right? ROFL

Well, I've moved the Acer into standby and put the HP on the podium. Now to continue the process of configuration and import of data.
The wifi has been on continually without a problem since around 10AM this morning. It's now about 8PM. I'll mark this problem solved.

PS - Thanks Claydoh for that tip on the "other installation" on GitHub. That did the trick!

Cool that it is working!
I wasn't sure if it would be useful or not, as I used the slightly newer github driver to (somewhat) fix random Bluetooth issues. This was ultimately fixed by hurling the card against the wall into a parts bin, and replacing it with a different one.

ROF,L!!!1
To do that I'd have to throw the laptop against the wall .... mmmm.....

My problem is still that I can see the AP's from the wifi of the cable modem but this HP laptopI cannot see the AP's from the Buffalo 600N DD-WRT wifi plugged into it. My Acer sees AP's from both wifi. I can't imagine what change in the BIOS would cause selective visibility of a wifi. So, I suspect that it is caused by the wifi driver itself.

During the last three/four years I've used the fiber optic from Allophone.com I've never used the cable modem wifi because (initially) there wasn't a way to configure it to my liking by assigning IP addresses using MAC addresses. Now there is, but it doesn't seem to help when I change stuff.

The driver for the rtl8821ce chip installed by your recommended process is 8821ce. It has a TON of PARM's to mess with. I also notice that it includes a secure boot module signature key. Since I have secure boot turned off why would it install that? I suspect that secure boot is my problem.

Something to work on, more fun to be had!

I have secure boot disabled, and did not notice any wifi connection errors, though I did not use it often - power or Comcast outages and the like, and using wifi tethering, mostly.

The hardest part of swapping out wifi on a laptop is usually snapping the teensy-weensy antenna plugs onto the new card Not that I am recommending that. But Intel cards are inexpensive.

So far, the rtl8821ce has stayed up since 10AM yesterday. Hope in continues, but if it doesn't, OR, I can connect it to the failure to see the Buffalo 600N wifi router then I've already downloaded an HP maintenance video describing how to replace it, AND more importantly, how to replace the 1TB rust bucket which is acting like an anchor chain on this box. As long as an app doesn't access the 5,400 rpm HD it runs very fast, otherwise. ... I'm not used to waiting for 5-30 seconds for an action that involves the HD to take place. IF there is an empty M2. slot inside I am going to fill it and use it as the boot drive and the 1TB as storage.

[GreyGeek]

Well, the wifi is staying up, but it is loading the error log with a ton of barf.... which repeated almost exclusively since I booted up a little past noon. Dmesg shows the boot up stuff and then gets right into the rtl6621ce warning msgs, which are continually through the rest of the log until the end at 12719.286089.

While checking the systemd journal (journalctl. -b) I noticed a reference to mdraid in the kernel listing. I did some checking and found

/boot/grub/x86_64-efi/mdraid09.mod

2.222261] raid6: avx512x4 gen() 55938 MB/s

Checking in the BIOS I found a raid option when was used with Windows, but I wasn't aware that it was in the BIOS and wasn't aware that Win10-11 used it. Regardless, the installation process attempted to make a raid device out of the 1 TB HD. I or the installation process never installed mdraid and checking the mods it turned out that during the kernel install the BIOS was consulted and a failed attempt to create a raid system occurred. "sudo btrfs filesystem usage" shows that Data is single and metadata and system are DUP. No raid is involved with the BTRFS subvolumes.

I've spent most of the day removing unused or unnecessary systemd services, which has reduced my boot up time from 1 min and 50 seconds to 30 seconds. I am also adding software and making configuration changes just to discover if any other surprises await me. When I am comfortable with this install I am going to take the Samsung 500 GB SSD out of my Acer and make it sda in this HP and do the whole installation over again, as a legacy with neither Secure boot nor EFI, avoiding the pitfalls, landmines and alligator swamps.

claydoh is right about Intel wifi. My HP Envy came with Intel Wireless, uses the iwlwifi driver and "just works" from install to now, a year later. Also, I installed Kubuntu 18.04 LTS with Secure Boot disabled and full UEFI, plus a couple of other BIOS/UEFI adjustments. Simple, clean, stable. It is strange how many different configurations a manufacturer will use in their product lines.

jglen490, do you have a product id, or sk, or an amazon link to that Intell Wireless? I found this one.

GG, I didn't buy the Intel wifi as a separate unit, it was built into my HP Envy.

Here's what K20.04 tells me:

sudo lshw -c network

https://www.amazon.com/s?k=intel+wif...ref=nb_sb_noss
this one is probably a good choice

They may be had cheaper on FleabBay, Amazon is quicker.
You might need to verify if your laptop for some odd reason uses a half-sized M.2 card, but iirc it will most likely be the standard full size one.

Do remember that the antenna plugs can difficult to line up snap on, at least for me. A magnifier helps, and maybe even very gentle use of some very small needle-nose pliers or forceps. If the mounting surface is flat and stiff/sturdy, a small flat screwdriver should work, if you can line the plugs up.
