I just upgraded one of my old PC's to ubuntu 16.04 and the Ethernet completely quit on me. It will act like its connected, but won't work.
Any help would be greatly appreciated. Thanks in advance!

Wireless Issues - Acer laptop

Hi All,

I'm hoping someone can help. I'm very new to Ubuntu but from what I've seen so far I love it. The only issue is I can't connect to my wifi network, the only method which will work is using my phone as a usb modem (laptop doesn't have an ethernet port). As much as I do want to stick with Ubuntu if I can't get the wireless working I will have to revert back to Windows. Anyway not going to give up yet!

So let's say I have a wireless adapter in my hand that is "compatible" with linux. Do I simply plug in and connect?

Ubuntu continuously dropping wireless connection - please help!

I actually found this forum by doing a search to try and fix my problem. What I found was a very old thread in which someone had my very same problem, and they were helped, so the thread was marked [SOLVED], however others have posted there for help and haven't been answered, and it seems obvious that its because they are posting in a solved thread. That is the reason I've created a new thread.

The thread I'm referencing above is here: https://ubuntuforums.org/showthread.php?t=1289484

Its clear in reading the thread that the person who needed help had a different cause for their problem, as I can see by looking at my own feedback that the text highlighted in bold in the topic is correct for me. That means something ELSE is wrong. Can someone look at this and tell me what is causing my connection to drop? I have to manually disable and re-enable the connection to get back online, and its a constant problem...

I'm not sure if this is helpful, but it may be worth mentioning that I use windows on the same machine and do not have this issue there...

hi guys,

i'm wanting to share my network connection on my ubuntu server with my raspberry pi zero thats plugged in via USB. Now i can do this on a windows machine without a problem and there is documentation around explaining how to do it with a windows machine. for reference: http://blog.gbaman.info/?p=699

does anyone know how i can get this to work via my ubuntu server? the server is headless so will need to do it all via command line. i've not used ICS within linux before and the windows one automatically worked

Currently I use ntm but it's last update is for 2011 and I have many problem with that in Ubuntu 16.04.1 . Is there any alternative for that?
If no, can you please help me to extract daily traffic usage in vnstat to write a script for that with cron like the follow script?
Code:
unit=$(vnstat -s -i ppp0 | sed -n 6p |  awk '{ print $9 $7 }' | head -c 1)
amount=$(vnstat -s -i ppp0 | sed -n 6p |  awk '{ print $8 $7 }' | rev | cut -c 2- | rev)
day=$(vnstat -s -i ppp0 | sed -n 6p |  awk '{ print $1 $7 }' | rev | cut -c 2- | rev)
//The bug is in the three lines above, I can't extract the daily usage because the number of lines change in some execution of vnstat
max=34
if [ "$day" == 'today' ]; then
    if [ "$unit" == 'M' ]; then
        if (( $(echo "$amount > $max" |bc -l) )); then

Hi, I got my brother's old PC, and it's running Ubuntu 12.04
I've always used Windows so I don't really know anything about Ubuntu or Linux.

I'm trying to connect to a wireless network, but it only shows Ethernet as an option.

when I connect a USB 'router' I can access the internet through it.

could someone please help me figure this out?

(perhaps it's a drivers problem?)

Hi


It has a problem with the connection between the vpn ipsec strongswan and Cisco vpn gateway.


Does anyone know what the problem might be? I tried to set up a connection already with two different hosts. Since my partner on the right side I have information that the phase 1 start properly. The problem occurs with phase 2. On the device is running dozens of other connections ipsec. On my website host is peer. Interface eth0 is set to an external address. On my side there's no NAT, all firewalls disabled. We have tried all sorts of encryption, hashing and groups pfs, psk certainly agree because the phase 1 start properly


When trying to connect I still have a problem:

Wifi Out of Range

Hello,
5 days ago my laptop suddenly stopped connecting to my wireless network and said that it was out of range. I had been using it the night before, however, in exactly the same position and nothing changed, so I don't understand why my wifi is 'out of range' now. I can connect to another wireless network in the house easily still.
Also, my sister's laptop which is a Windows 10 can connect to the particular network that I can't connect to, so it isn't the network's problem,but my computer.
I have an Ubuntu 14.04.
Idk much about computers, so I am really not in the know about what I should do. Can anyone tell me what my problem is???
Sorry if I'm not posting this right.

Wifi will not restart

I am thinking this is a problem do to the fact that the drivers for my wifi are just not quite right. I may have to live with this problem.
First the setup I have a Toshiba Satellite P875-S7310

Link to it here:
https://www.amazon.com/dp/B00BQKW45M...=IS2DHKH9UXT0B

I put 16.04.1 LTS (Xenial Xerus) with Mate 1.12.1 on it. Wifi works just like it should after powering up BUT if for any reason the wifi is signal is dropped (the signal only, so if internet is down but the signal is still up and running NO PROBLEMS at all) none of the wifi networks will show up anymore. This is been a long long bug I have been trying to fix so I can not get into all the dead ends here it would be a small book. :P I tried using different network managers like wifi radar and wicd but dead end there.

You can get the same result if you put "ifconfig wlp2s0 down" into the command line. (the "wlp2s0" being different on some computers)

So here is an example of the problem. Everything normal then router goes down for a bit but then I can no longer see any wifi signals at all. I would think that just putting in "ifconfig wlp2s0 up" into the terminal should restore the display of the wifi signals but NOPE. Now when this happens if I run different network managers like wifi radar and wicd I can see the wifi signals and I can even hook up to them kinda . . . it shows that I am hooked up and when I run the "system monitor" program I can see internet traffic (like pings or something) but I can not run anything that hooks up to the internet like firefox, bluemoon, Konqueror, thunderbird, podcast down-loaders etc. Well I can run them they just can not see the internet. It also happens a LOT in fact about 90% of the time It will happen when I try to switch to a different wifi network.

The only way to get internet back is to restart the computer and that can be a real pain in the butt when I have certain projects going on.

Problem solved would be ideal but I would be happy if I can have even a work around. The work around I am thinking of is to just restart the "stock" wifi network manager (I am sure it has a name I just have no idea what it is) I tried to just do a command line of "ifconfig wlp2s0 down" then "ifconfig wlp2s0 up" but that is not shutting down the whole wifi network manager just the connections and does nothing to being it back up after it fails. If there is a command line to where I can shut down the WHOLE wifi network manager and then start it back up again I think that would work as a good work around to the problem.

I am just lost when it comes to command lines.

Thanks for your time reading this long mess :)

No wireless or Wired connection - can see and connect to router though?!?!

Hi All,

Reasonably new to Ubuntu....

I have version 16.04 and up until a few weeks ago everything was fine but now appear to be suffering chronic connection issues. I've run dry on my knowledge and looking to see if you might be able to help. I can both see and connect to my router but am completely unable to connect to the internet. I have other devices, including further Linux platforms working OK on their connections and have checked that all router settings are not inhibiting the issue. I can ping these devices all with positive response but am unable to ping outside of this network...having tried both named conventions and IP addresses.

The problem occurred seemingly overnight when I attempted to load up the internet with no changes that I was aware of.

I have included the code and results of a number of commands, hopefully you guys might be able to shed some light on the issues for me.

Cheers

[lubuntu] ipw2200 with problems after a update

Hello

Some time ago, I had a issue which cause my notebook to reach over 90°C due to a wireless error. It was caused because there was no adequate module loaded. The old issue: https://ubuntuforums.org/showthread.php?t=2333925

Since last week, this issue is back again. However, instead of the module ipw2200 not being loaded, it is loaded but stops working. A dmesg message about ASSOCIATE command being already sent is shown, and then the wireless stops working, CPU reaches 100% usage. To restore the wireless, suspending and returning makes go it back to the normal state. With the module, the wireless would work flawlessly for over 48 hours. Now it may stop after boot, after 3 hours, after 12 hours. I've found no pattern.

When this error happens, exactly the same error messages as if the module was not loaded appears. What I noticed this time is that the ASSOCIATE message is the first one that appears.

Code:
[ 8326.112600] ipw2200: Failed to send ASSOCIATE: Already sending a command.
When suspending:

Code:
[10129.517088] wlp1s5: Going into suspend...
[10129.536344] ipw2200: Firmware error detected.  Restarting.

[10129.567133] ipw2200: Unable to load firmware: -22
[10129.567133] ipw2200: Failed to up device
I am not sure, but my suspect this update caused the issues:

I have dual booted Ubuntu 16.04 and have problems in my wi-fi connection. First it was disabled and greyed out and I applied many solutions on this forums. Now, there is a very weak Wi-Fi signal showing up which doesn't connect.

Intel Wireless 8260 regularly deauthenticating

This problem is occurring only at my workplace, which has two networks, one 2.4GHz and one 5GHz (problem occurs on both). Every 10 to 30 minutes I lose connectivity for a few minutes (or until I reconnect to the network). I've noticed that when this happens all other networks disappear from the list of available connections.

The corresponding log in dmesg (which doesn't always show up when connection cuts out) indicates that my machine is deauthenticating for some reason.

Code:
[Oct 6 11:31] wlp4s0: deauthenticating from c0:56:27:41:ef:5f by local choice (Reason: 3=DEAUTH_LEAVING)

[  +0.092040] wlp4s0: Limiting TX power to 27 (30 - 3) dBm as advertised by c0:56:27:41:ef:5f
So far, I've tried disabling power saving and ipv6, but neither of these had any effect and the latter just silenced all errors in dmesg. I'm attaching the output of the wireless-info script, if anyone has any idea what might be going wrong or how I can go about debugging this I would greatly appreciate the help!

Use Ubuntu to Create ad hoc wifi network + act as file server

Is there a way to take a computer running Ubuntu (16.04LTS) and have it create its own ad hoc wifi network (that other devices could connect to, albeit without any internet connectivity) and then serve files to the devices connected to it?

I'm going to take my kids on a 14 hour trip. We used to have a Seagate Satellite (battery powered, HDD with embedded file server) that the kids used to stream movies and watch on their tablets and phones. Sadly, that device has gone AWOL. (I suspect someone in the family loaned it out and it was never returned). Anyway, I don't want to spend $200 to buy another one if I can improvise one.

I own a few Intel NUCs (tiny computers about 4" x 4" x 3") that run Ubuntu. If I could (1) make it create an ad hoc wifi environment that up to 4 devices could connect to and (2) use the wifi to serve/stream movies to the kids' phones and tablets, I could make this work without having to buy anything.

Is this doable?
