Wifi Internet connection not starting at bootup

[Dingo]

Woof woof!

I was playing with Xenial on my Thinkpad L440 and easily settled connection with iwlwifi driver (Intel Centrino Advanced-N 6235 card) but, after created savefile and rebooted, I noticed that WiFi interface is not starting up automatically. I need everytime to manually setup wireless wizard. Do you know how can I solve this?

[bigpup]

What version of Xenialpup 7.5?
32bit or 64bit?

Have you run Quickpet->Info->Xenialpup updates
Saved and rebooted so the new changes are now being used?

What network connection program are you using?

You are selecting the normal boot entry in the boot loader menu?

What device is Xenialpup installed on?
USB drive, internal hard drive, CD/DVD??

64 bit

Not yet, in fact now I remember I have forgotten to do this.
Update: I just installed updates, but same issue

What network connection program are you using?

Network wizard

On USB drive, I'm waiting for new dvd burner since this I have is faulty

[Dingo]

Some progress in troubleshooting wireless issue at bootup with savefile. I checked and I noticed that an APIPA address (169.254.xxx.xxx) is assigned automatically (issues with dhcp?)

[rcrsn51]

(issues with dhcp?)

Yes. It's probably a timing problem. Your Internet connection software is trying to acquire an IP address via DHCP before your Ethernet adapter has fully initialized.

[Dingo]

(issues with dhcp?)

Yes. It's probably a timing problem. Your Internet connection software is trying to acquire an IP address via DHCP before your Ethernet adapter has fully initialized.

So it is the ethernet adapter that is interfering with my wifi?

[rcrsn51]

Sorry. I should have said "WiFi adapter".

Dingo,

The latest version of the network wizard, network_wizard-2.1.3, waits longer for the wired ethernet adapter. It is available at:
viewtopic.php?p=2241#p2241.

Please try it to resolve the timing issue. If it doesn't, please tell me.

You may have discovered that your wifi device is claimed by multiple drivers. The network wizard might not account for that correctly. I recently updated the simple_network_setup (SNS) tool to handle that situation. So, you could try that tool, simple_network_setup-2.4, available at the same posting.

network_wizard-2.1.3 failed to solve my issue

While it seems that simple_network_setup-2.4 solved issue. At least, I installed, settled connection, rebooted and at next boot Wlan0 interface was live and working

Thank you for this info. It seems that SNS is a success for this problem.

Are you interested in pursuing a fix for network_wizard? We could start by your adding to /usr/local/network-wizard/rc.network, "set -x; exec >&2 #DEBUG" just after the history comments and sending me the /tmp/bootsysint.log and /tmp/xerrs.log, or a pdiag tarball.

My focus has been on perfecting SNS and frisbee. Do you think it would be worthwhile to fix NetWiz?

Surely. I'm available for testing. Where precisely should I add the line

set -x; exec> & 2 #DEBUG ?

[rerwin]

Duh! I remembered as I was eating lunch, that I did not say where to put the line. It's in /usr/local/network-wizard/rc.network.
set -x; exec >&2 #DEBUG

The"#DEBUG" is only to make it easy to find, to remove it or comment it out. I wouldn't put spaces in ">&2", but maybe it would be OK. It puts the trace data into the error log so it will appear in xerrs.log as well as in bootsysinit.log.

this is the pdiag tarball, should I add also

bootsysinit.log
xerrs.log ?

Thank you. Those logs are included in the pdiag.

The bootsysinit.log does not show the trace of rc.network. The logs seem to indicate a successful connection. I need to see what happens when you reboot and do not get automatic connection.

I gave you incomplete instructions about the "set -x..." edit.

• Please install network_wizard-2.1.3 and network_connect_update-20200722 from
  viewtopic.php?p=2241#p2241, then

• Edit /usr/local/network-wizard/rc.network, line 65 (blank) to add:
  set -x; exec >&2

• Then create a new connection and verify that it works.

• Then reboot and (I assume) see Puppy fail to automatically connect.

• At that point, run pdiag to create the pdiag tarball.

Sorry for the confusion. I forgot that xenial has rc.network in a different place than more recent pups.

[Dingo]

@rerwin
here the pdiag tarball after installing network_wizard-2.1.3 and network_connect_update-20200722

[rerwin]

Thanks for the pdiag tarball.

I see that wpa_supplicant fails, but have not determined why. I ran netwiz and discovered that my PC required me to insert a sleep early on, so the pci wifi adapter shows up. But your device is recognized normally.

In the absence of an "ah-hah', please try inserting that sleep in case there is a timing issue that manifests differently on your PC. Using network-wizard-2.1.3, in /usr/local/network-wizard/rc.network, insert after line 351 and before the line "stop_all -a >/dev/null 2>&1":
sleep 4

Then reboot and get a pdiag.

if it works, try reducing the sleep to 2 seconds, which is what my PC required. No additional pdiag needed.

If the sleep doesn't help, another thing to try would be to add the trace statement (set -x; exec >&2) to the SNS 2.4 rc.network and run SNS, reboot and get a pdiag. That way, I can compare the traces to possibly find anything different in the startup of the wifi device. The trace statement should replace SNS 2.4 blank line 39 in /usr/local/simple_network_setup/rc.network.

I think I will also rerun my netwiz test but with a USB dongle, in case that makes a difference (versus the pci adapter).
Richard

[Dingo]

I added

Code: Select all

sleep 4

to /usr/local/network-wizard/rc.network but without success and this is a pdiag log

Now I'll create another pdiag log running sns

[Dingo]

@rerwin

and this is the pdiag while running sns as default tool

Thanks for those pdiags.

The SNS pdiag shows that SNS handles your connection as one would expect. Right?

Although I have been silent for a while, I have been experimenting with the network wizard with PCI and USB wifi interfaces, and both WPA2 and WEP encryption. I found a few things to fix. But I am not sure whether the fixes will help you.

In checking your network wizard pdiag, I see that it does not capture the netwiz setup files. That function was added in bionic pup.

I would like you to test with later versions of netwiz and pdiag, hoping that will get us closer to understanding what is happening.

Please install the following in a fresh xenial pupsave environment:

• network_connect_update-20200722 from viewtopic.php?p=2241#p2241

• pdiag-20171205 from http://distro.ibiblio.org/puppylinux/pe ... 171205.pet

• network_wizard-2.1.4-beta which I sent you in a PM

Run NetWiz and scan and save a profile for your problematic device and network, then use that profile to connect. Save the configuration when prompted. If the device is not detected or the connection fails, get a pdiag.

If the connection succeeds, reboot (saving if necessary) and get a pdiag.

Are you using encryption type WPA or WPA2? Be sure it matches what the network/access point expects.

Thank you for your patience with this process.
Richard
