3d. If you switch to a different wireless type (802.11g or 802.11n if
you are using 802.11g) does this change anything?*It is worse if I set the
wireless to 802.11b/g/n
3e. What channel specifically are you using when this problem is
reproducible?*Tried with almost all of them, same problem. I left it set to
auto in the end.
3f. In order to understand the wireless environment your AP is working
in, please provide the output of the following terminal command:
sudo iw dev wlan0 scan | grep -i "ds parameter set"
*[john@john-X555LAB ~]$ sudo iw dev wlan0 scan | grep -i "ds parameter set"
command failed: No such device (-19)
3g. What encryption type are you using (ex. WEP, WPA2-PSK, etc.)?WPA-PSK
3h. If you change and remove encryption entirely does this change
anything?Tried with other encryptions, iven leaving it open but no change.
3i. Do you have QoS (Quality of Service)/WMM (Wi-Fi Multimedia)
enabled?*QoS not available for this router see forum
https://community.vodafone.ie/t5/Technical-Support/QOS-possible/td-p/196882 for
more info.
3j. If you disable/enable QoS/WMM does it change anything?*not possible
to disable as it does not exist.
3k. What is the current beacon interval (usually default is 100)?*There
is no way of changing it
3l. If you adjust this to 50 does it change anything?
3m. Does your AP have a firewall enabled?*No
3n. If you enable/disable the firewall does it change anything?*it
doesn't change anything
3o. What frequency are you using (2.4GHz, 5GHz, etc.)?*My router
doesn't say anything about it.
3p. If you change frequency does it change anything?
Does another wireless device tested with the AP have the same problem as
the hardware you initially reported with?*I have another computer desktop and
there is no problem with it. Also the same laptop computer having problems if I
boot it with Windows 10 it's totally fine.
What is the distance of the wireless device from the AP?*8 meters.
What is the number and type of obstructions between your device and the
AP?* There is just a wall but plz this is not the problem as from the same
position the laptop works fine if I switch to Windows 10 as booting OS.
6a. If you bring the device close to the AP and eliminate obstructions,
does this change anything?*No, it doesn't change anything
Does the issue occur with different APs?Yes.
Is it a regression (i.e. did the problem happen in a prior Ubuntu
release)? If so, what release specifically did it last work with? If you
do not know, could you please test for this in the earliest release of
Ubuntu that is supported as per Ubuntu Releases?*I tried with all Ubuntu
releases since I boought the laptop and it never worked.
Could you please test upstream's compat-wireless backports via
https://wiki.ubuntu.com/Kernel/LinuxWireless#Compat-
wireless_from_upstream? Please mention in your report the specific
version you tested.*There is no precise instructions on how to test
this. I followed the link and all I did was downloading the object via
git....I got lost after.
If the above backport did work, does this problem occur in the
newest mainline kernel following
https://wiki.ubuntu.com/Kernel/MainlineBuilds? Please mention what
specific version of the mainline kernel you tested with in your report.
If the mainline works, does either the development release or the
Ubuntu provided stable compat-wireless backport work following
https://wiki.ubuntu.com/Kernel/LinuxWireless#Compat-wireless_in_Ubuntu?
Please mention in your report the specific version you tested.
Only for Broadcom wireless chipsets, does the Broadcom STA driver
work following
https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx? Please
mention what specific version of Broadcom STA you tested with in your
report.
Only for Realtek wireless chipsets:
13a. Does disabling the firmware power management change
anything? This may be done via a terminal:
sudo nano /etc/modprobe.d/rtl8821ae.conf
options rtl8821ae ips=0 fwlps=0
where DRIVER is the kernel driver in use for your card found by
executing at a terminal:
lspci -v
13b. Does the upstream proprietary Realtek driver downloaded
from http://www.realtek.com.tw work? Please mention what specific
version of the drivers you tested with in your report. If it doesn't
work, please contact the card vendor, for example ASUS (not Realtek),
file a case number requesting the driver be fixed, and post the case
number to your report. * Realtek has no drivers for Linux
Only for Intel wireless chipsets:
14a. Please advise to which firmware version the device is
using. Stating the linux-firmware version (ex. apt-cache policy linux-
firmware), while necessary, is not the firmware version in use, but the
package version of linux-firwmare. In order to find the version in use,
one may check dmesg. For example, if the chipset was using the iwlwifi
driver:
cat /var/log/dmesg | grep "firmware version"
[ 2.820714] iwlwifi 0000:03:00.0: loaded firmware version 25.222.9.0
op_mode iwlmvm
For more on this, please see here.
14b. Did this work on a prior linux-firmware version? If you don't
know, please test a prior release and advise to which version of the firmware,
and kernel you tested specifically.
14c. Does this work, or have a measurable positive impact using the
latest firmware available from Intel? If you don't know, please test this with
the latest mainline kernel, and firmware available for your chipset.
Does ndiswrapper work following
https://help.ubuntu.com/community/WifiDocs/Driver/Ndiswrapper?*I got
lost. It's too much for me. Please mention what specific version of
ndiswrapper you tested with, and a link to the Windows driver you used
in your report. Info <!> If ndiswrapper does not work, you are welcome
to file a new bug report by executing at a terminal:
ubuntu-bug ndiswrapper-utils-1.9
