My wifi problems with different systems are relative, not absolute. They seem more likely to happen on this slow machine with a recent system. Several things make me suspect timing. I tried to install Peasy WiFi 4.2 and probably screwed it up. I never could get a scan showing any networks.

I still don't understand why I can sometimes connect if I go back to interface setup before trying to connect, when repeated attempts to use an existing profile fail.

Re: Wifi issues
There is an informative thread regarding Slackware and dropped connections in the linuxquestions forum
Suspects:
Driver/firmware for the problematic wifi card (Identify and make sure is the latest for your kernel)
dhcpcd (replace with dhcpclient that appears ok)
11n wifi band (inactivate in module.conf)
IPv6 (inactivate in modules.d)
Regional settings (set correctly with "iw reg set <2 letter country code>)

However, my first guess would be to change "slaac private" to "slaac hardware" in /etc/dhcpcd.conf or comment it out totally as it both hits on dhcpcd and IPv6

Wifi issue.

Slacko 6.9.9.9 32bit

Based on mavrothal's post.

I looked at the /etc/dhcpcd.conf in Xenialpup 7.0.8.1.
It is much smaller and has less commands in it, than the one in Slacko 6.9.9.9.

Idea So, I replaced /etc/dhcpcd.conf with the one from Xenialpup 7.0.8.1.

Shocked So far it seems to be working.
Wifi is working OK with no problems.


I will test for some time and see how it does!!!

This is the /etc/dhcpcd.conf I am now using:
Code:
# A sample configuration for dhcpcd.
# See dhcpcd.conf(5) for details.

# Inform the DHCP server of our hostname for DDNS.
hostname
# To share the DHCP lease across OSX and Windows a ClientID is needed.
# Enabling this may get a different lease than the kernel DHCP client.
# Some upstream DHCP servers may also require a ClientID, such as FRITZ!Box.
#clientid

# A list of options to request from the DHCP server.
option domain_name_servers, domain_name, domain_search, host_name
option classless_static_routes
# Most distributions have NTP support.
option ntp_servers
# Respect the network MTU.
option interface_mtu
# A ServerID is required by RFC2131.
require dhcp_server_identifier

# A hook script is provided to lookup the hostname if not set by the DHCP
# server, but it should not be run by default.
nohook lookup-hostname


UPDATE:
After 3rd reboot.
Wifi is back to not working correctly.
Slow and cuts off and on.
So, this did not fix it. Twisted Evil Evil or Very Mad

Seems strange that several things I have tried, seem to fix it, but not for long term. Exclamation

I have had the best results using the 4.9.13 kernel.

/root/.packages/woof-installed-packages contains cd-paranoia.
Code:
libcdio-paranoia-10.2+0.93+1|libcdio-paranoia|10.2+0.93+1|1|BuildingBlock|240K|slackware64/l|libcdio-paranoia-10.2+0.93+1-x86_64-1.txz|+libcdio|CD paranoia libraries from libcdio|slackware64|14.2||

Can't see any apps depending on this.
The ripper included in Slacko is a pMusic frontend, and it does not use cdparanoia..

This strongly suggests a nondeterministic problem involving multiple processes and race conditions. It might be fixed on individual installations by inserting delays, but this will vary as you go to different hardware.

I am particularly puzzled by a number of situations in which scanning for networks doesn't find anything in an environment with half a dozen networks seen on another device next to this machine. Even when networks are found they are surprisingly weak, even though the router/AP is in an adjacent room. When the machine succeeds in negotiating a connection I always find signal strength higher than seen during the scan. What???

The machine is problematic, even running other systems, but it isn't completely unusable. The probabilities change.

@bigpup: If you suspect that the problem is caused by dhcpcd and want to rule it out as the culprit, you should try a connection manager that doesn't use it, like PWF.

rcrsn51,

I did not know that about PWF.

I will try it and report back.

Thanks for your contributions to Puppy!!

rerwin updated his dhcpcd-dropwait sources so I built them for 32 and 64. Probably best to save the pet somewhere and install it in a pristine boot before configuring the network. The dhcpcd.conf is a bit simpler but if you use frisbee that has its own dhcpcd.conf anyway.

Make sure you get the correct version for your system. If not sure run uname -m in a terminal.

01micko,

Wifi issue.

I will try that new dhcpcd and test to see if it helps with my issues.
Playing with dhcpcd did help, just not 100%.
Maybe your new pet will do it.

I will report findings.

I have not 100% determined this is not something to do with the rtl8821ae firmware.
Newer kernels seem to help and they are probably using newer firmware drivers.
This driver has had issues in the past and not sure they all got corrected.

Idea I think I will also try the newer firmware idea and see how that works.

I am so happy I have my computer in a room with no windows.
It would not be in that room, if there was a window! Laughing

Tried PWF

It helped to make improvement in WIFI issue, but not 100% fix.

I am starting to think I may be dealing with rtl8821ae firmware issues.
Newer Linux kernels, seem to work better, and a Google search brings up a lot of the same issues, I see, for this rtl8821ae firmware driver.

Any ideas on how to get a newer firmware driver?

My best results are when using the 4.9.13 kernel.
That is the newest one I have tried.

If you go here and look under rtlwifi, there is a version of rtl8821aefw_29.bin dated 2017-01-06.

@bigpup,

I'm encountering some weirdness with the rt2500, for which the firmware should be stable. Part of the problem is not your firmware. Nothing prevents multiple layers of problems.

I've now installed the 32-bit i686 version of dhcpcd 01micko provided, and things look better. We'll see how this holds up. At the moment I'm not using PeasyWiFi on this installation because I want to test dhcpcd.

Running tahrpup 32 6.0.5 on this same machine I reached the point where I have decent WiFi management with either the Dougal network tool or PeasyWiFi 4.2. Ran for several hours.

If this one holds up as well, I'd say we're ready to release.
Added: on this one problematic machine it has now been working for several hours.

Minor problem which may be strictly personal: the activity graph on the panel is almost invisible. Running on a slow machine with no blinken-lights for disk activity, (because there is no disk,) I need some visual cue to tell if a browser is eventually going to wake up. Launching two instances of a browser that would like all RAM is painfully slow and confusing.

Another very minor quibble: how long should it take to update the status of the drive icons? I've seen a drive icon sitting there for over a minute after I had unmounted and removed the drive. Eventually, I restarted the X-server to refresh the drive icons.

@bigpup - you can actually try the 64 bit k4.9.30 in 32 bit on your box - if nothing else it will tell us it might work better - or not! If it does work then I can compile 4.9.3x for 32 bit and probably ditch the palemoon isos and use firefox. I doubt firmware will make a difference because the kernel-kit build script has an option to get latest firmware which I always use. Also, there probably exists a manufacturer driver on github - I have an rtl8192eu dongle that has no in kernel tree driver and I just built it for 64 bit, posting from it now.

@prehistoric - I have dillo browser built but not uploaded - although I see there is a version in slackware-extra repo if you search ppm. It's tiny and fast but not altogether compliant with these new fancy web-pages so I suppose it would depend on what you want to to do with it; netsurf is also available.

As for icons not refreshing - yes I have seen it on slower kit. jlist did do some work on those so I'll raise an issue on github.

@zigbert
Code:
# ldd `which mplayer` | grep paranoia
   libcdio_paranoia.so.2 => /usr/lib64/libcdio_paranoia.so.2 (0x00007fc4dc25d000)

I saw it happen in a new build of Stretch yesterday too, when clicking on my fat32 drive. I'm quite sure it's the "two pinboards" bug again, because if I go to /root/.pup_event, the icons are mounted correctly there, and afterwards, changing the wallpaper complains about the wrong pinboard. Before it used to happen when you change the hostname in PUPMODE 5, but now it seems to have taken on a new form, possibly in savefiles... but I haven't found a consistent way to trigger this new version yet.

Tried a bit slacko64 on my MacBook Shocked
To begin with here is the Broadcom wl wifi driver, as b43 does not work on Macs
It also needed to force the "uxa" AccelMethod for the intel driver and disable some pesky gpe interrupts that flood the CPU.
One think I could not manage is to get it detect the touchpad properly or even just load the synaptics driver. Not sure if it is Xserver, udev or kernel. I should just point out that Mint handles it perfectly and fd710 adequately. Slacko's is unusable really (cmon Mick, I know you have a macbook at home Cool )

One other thing. Cryptsetup is not in the main sfs so the LUKS encryption option is not offered at shutdown.
I also compiled the broadcom facetime camera driver but although is loaded fine and activates the camera is giving no image and a lot of GPU complains. If anyone wants to take a further look let me know so I upload the pet (or try it yourself compiling from source)

That's it for Pup MacSlack Very Happy
