Also, please post in your report both the question and answer, as the presentation of the information here can change:
What is the full computer model number (ex. HP G32-301TX Notebook PC)?*ASUSTeK COMPUTER INC. X555LAB
If you update your BIOS to the newest version following the guide here, does this change anything?
*It did change actually after having upgraded to the newest. Before it used to freeze the internet connection while now it is just unstable.
Regarding your wireless Access Point (AP):
3a. What is the current AP manufacturer, full model, revision, and firmware version?*
Product type HG658c
Device ID F83DFF-
Hardware version HG658BZV VER.A
Software version V100R001C172B227
Batch number BC172P0.
3b. If you update the AP to the latest firmware does it change anything?There is no update from Vodafone.
3c. What wireless connection type are you using (802.11ac, 802.11n 150/300, 802.11g, etc.)?*802.11b
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:/
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:/
If the above backport did work, does this problem occur in the newest mainline kernel following https:/
If the mainline works, does either the development release or the Ubuntu provided stable compat-wireless backport work following https:/
Only for Broadcom wireless chipsets, does the Broadcom STA driver work following https:/
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.
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://
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:/
