[ubuntu] Bluetooth not working (Dell XPS 15 7590)

July 16, 2019, 3:42 am

Hello all,

I just got my XPS 15 7590 last week and I am now trying to set up ubuntu 16.04 on it as dual boot.

The wifi did not work at the beginning and I found a solution here https://support.killernetworking.com...-ubuntu-16-04/ This is because XPS 15 7590 is using Killer AX1650 chipset.

After I followed the instructions above, the WIFI works, but the Bluetooth not.

This is the information I got by

Code:

rfkill list

Code:

0: phy0: Wireless LAN

    Soft blocked: no

    Hard blocked: no

1: hci0: Bluetooth

    Soft blocked: no

    Hard blocked: no

This is after running

Multiple IP on Bridge Interface

July 16, 2019, 7:47 am

≫ Next: how to set a fixed ip on lan with ubuntu core?

≪ Previous: [ubuntu] Bluetooth not working (Dell XPS 15 7590)

I have a VM where I've created a bridge and assigned the IP address to the bridge interface. With one IP, this works okay but if I assign a second IP to the bridge interface, I am unable to reach the VM from outside. However, if I console into the VM and ping to an external address, the VM becomes reachable. It seems the VM is not sending out arp queries with two IP's assigned to the bridge interface. I could setup a job where I ping every 60 seconds but that would be a hack and I would rather address the root cause if there is one. Why am I doing this, the VM's are Kubernetes worker nodes with a different CIDR. I am running FRRouting on the VM and I would like traffic from the containers to have a default gateway as the second IP on the bridge interface and all traffic from a VM (whether host or containter) to be handled in the physical network once it leaves the VM.

It seems setting the values below in /etc/sysctl.conf might help but I do not fully understand what they are supposed to do.

net.bridge.bridge-nf-call-ip6tables = 0
net.bridge.bridge-nf-call-iptables = 0
net.bridge.bridge-nf-call-arptables = 0

I have thought of using gratuitous arp but you have to issue the command, would that be a viable direction? Any help is appreciated.

mirror traffic from one VM to another?

≪ Previous: how to set a fixed ip on lan with ubuntu core?

I have a need to mirror the traffic from one ubuntu (virtual) server to a windows host. I have found that Daemonlogger or even tc would allow me to mirror traffic from one interface to another - but thats only 1/2 my need -

i need to have that mirrored traffic sent to another virutal server.

is anyone aware of a document they could point me to that might help me determine how to do that in vmware?

thanks.

Internet connection constantly dropping on home network

July 17, 2019, 2:39 am

≫ Next: [lubuntu] Can't connect to WiFi - Lubuntu & Windows 10 Surface Go dual boot

≪ Previous: mirror traffic from one VM to another?

I have Dell XPS with Ubuntu 18.04. Whenever I am using my home network (and only this specific network), my internet connection keeps on dropping at random points in time. The network itself seems to be working as intended: other devices (as well as this same laptop when running Windows) work just fine.
However, I still have the feeling that the problem lies in how my home network was set up. It consists of a wireless modem and two access points. Whenever I am close to the modem, the internet connection seems to be more stable. When I move further away (and nearer to one of the access points), the connection starts dropping more and more often. Again: this only happens when running Ubuntu.

Any ideas how to solve this? Thanks!

I can connect to the ethernet, but my nm thing in the tray says "wifi networks: Device Not Ready"Also, I installed wicd and it says its scanning for wifi networks but can't find any. Windows 10 wifi works fine.

I'm brand new to Linux, and this is me dipping my toes in with Ubuntu. Any help at all would be hugely appreciated. Thanks in advance!

[kubuntu] forgot wireless password and it doesn't exist on my command line list

≪ Previous: [lubuntu] Can't connect to WiFi - Lubuntu & Windows 10 Surface Go dual boot

I've forgotten my wifi password and I'm using a computer with a wired connection. ls from the command line only lists the wired connection, although my previous laptop used the wifi connection. The list of available wireless connections does show it however. I guess I could just add a new connection and delete the current one, but I don't know the ssid or the key. I don't have my kde wallet password and my /etc file seems to be corrupted. I will greatly appreciate any help!

≪ Previous: [kubuntu] forgot wireless password and it doesn't exist on my command line list

Could not find a better category to post into.

As the title says, Ubuntu is hosting http://connectivity-check.ubuntu.com/, which is the default captive portal check server and which is hosted with Google Cloud. Instead, could this service not be hosted on one of Ubuntu's own servers? I am sure Ubuntu has the capacity to do this. Not sure why this one thing had to be offloaded to GC for a company the size of Canonical. Also, would be a privacy improvement, albeit symbolic.

Thanks.

I also ran rfkill command, I saw this

1 bluetooth tpacpi_bluetooth_sw unblocked unblocked
2 wlan phy0 unblocked unblocked

Not sure why line No.2 has wlan type there, It could be something I did this morning when I tried different way to fix the issue, I am not sure if it is correct or not, I think it should be wlp4s0.

I came to office this Sunday morning, try to fix it but I could not get it solved after I spent few days on it. I'll appreciate if you would help me solve the puzzle.

I can provide more information if needed

Thank you!

Help with network adapter (rtl8821ce) in Ubuntu

July 21, 2019, 10:10 am

≫ Next: [xubuntu] Xubuntu 18.04 - Bluetooth Issue

≪ Previous: [ubuntu] No Wi-Fi Adapter Found - ubuntu 18.04 ThinkPad

I have never used Linux before. I installed Ubuntu (ubuntu-19.04-desktop-amd64.iso) on my flash drive using Rufus and there seems to be no support whatsoever for the network adapter (Realtek Semiconductor Co., Ltd. RTL8821CE 802.11ac PCIe Wireless Network Adapter). Everything works fine in Windows 10. Windows 10 is my only available platform to access internet or any networking on my Lenovo IdeaPad S145 laptop. I use WiFI.

I cannot find the Linux driver for this chipset. Even if I did, I have no idea how to install or compile it. Im unfamiliar with Linux and its command line functions. What little documentation I found online suggests using a temporary wired ethernet connection to help with installation. Unfortunately, I dont have that option in Ubuntu.
Could someone please provide elementary step-by-step instructions to get this network adapter working so I can access the internet on WiFi. I would like to eventually get away from windows.

Hope someone can help.
