[SOLVED]manage wlan connections on startup

Hi guys,
so I just installed my ArchLinux and everything just works great and fast. Really love the Arch way so far.
But I'm having a question how to deal with my wlan-connections on startup.
I installed Arch on a laptop and while I'm at home I want it to connect to my wireless network on startup which is fine and no big deal, so I'm letting the net-profiles daemon do his
job and connect on startup.
But when I'm not at home, using my laptop at a friends place or cafe I dont want the boot process taking up all day to boot because he can't find my home network.
Which way would be the fastest to scan for my home network but if undiscoverable just not using my wlan-card atm.
thanks

Hello,
Maybe use net-auto-wireless? Personally, I background the @net-profiles in rc.conf, so the system loads fine even if there's no connection available that I can / want to use.

[SOLVED] Problem with adding a SSH connection to startup

you need -f, which sends ssh to the background, and -N which does not execute a remote command.
If you need it to run as a user other than root, then you probably need to utilize su as well.
it didnt work either. i am putting it in rc.local but doesnt work.

Thinkpad X220: bad wlan connection when docked and lid closed

Dear forum
I use a Lenovo ThinkPad X220. I have no trouble with the wlan connection when i use the notebook alone. The wlan connection is also stable when i use the notebook plugged in the dockingstation with the lid open. But when I use the notebook plugged in the dockingstation with the lid closed my wlan connection drops regularely to about 2 Mbps and gets very unstable.
The ThinkPad uses the Intel Centrino Advanced-N 6205 wlan network controller:
$ lspci | grep 6205
03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34)
The network controller uses the iwlwifi driver, that comes with the current linux-firmware package:
$ pacman -Ss linux-firmware
core/linux-firmware 20150206.17657c3-1 [Installiert]
Firmware files for Linux
I didn't change any options of the kernel module, everything runs in default mode:
$ modinfo -p iwlwifi
swcrypto:using crypto in software (default 0 [hardware]) (int)
11n_disable:disable 11n functionality, bitmap: 1: full, 2: disable agg TX, 4: disable agg RX, 8 enable agg TX (uint)

power_level:default power save level (range from 1 - 5, default: 1) (int)
fw_monitor:firmware monitor - to debug FW (default: false - needs lots of memory) (bool)
At first I thought, the problem could be caused by the KDE power saving settings. I changed the settings, so nothing happens when I close the lid (no hibbernation or screen lock or something like that), but without success (the wlan connection is still unstable under the described circumstances).
Also dmesg shows nothing that points out a problem (as far as I can see):
$ dmesg | grep iwlwifi
[ 19.688522] iwlwifi 0000:03:00.0: can't disable ASPM; OS doesn't have ASPM control

So I have no idea where this strange behaviour comes from (only wild guesses: buildfactor, antenna orientation,...).
Any help would be really appreciated.

hmmm...
how about checking both your wired and wireless nic drivers in device manager to make sure that the "allow computer to turn off this device to save power" checkbox on the power management tab is deselected.

Re: Satellite M50-216 - WLan connection keeps disconnecting

Model M50-216
I can connect to my hub no problem, and as a comparison I have another Laptop (dell) that never eperiences the problems I get with the Equium. Here's what happens.
I connect no problem, then it may work fine for 5 mins or an hour, then it disconnects, I can still see the network and it will happliiy connect up again. I have tried at my friends house with a different router and the probelm remains, so its not a router problem.
From a configuration viewpoint, I have windows managing the network connection.... ANY IDEAS??

Did you try to update the WLan driver and the BIOS?
In many cases this is the key to solve such WLan dropping issues.

Wlan connection slow

Hi,
since a few days I have big problems with the WLAN-connection of my late 2011 13" Macbook Pro that leads to very slow Intenet Connections and Slow SMB-Server access.
In Detail: If I will open a Webpage it will take 50 times longer then from my iPad or Windows PC; and I run an Windows 2012 Server as an Data Pool, if I will access to any Remote Hard disk the Mac will need 5-10 sec. to load a Folder (the Windows PC loads it directly after the "klick").
Intristingly, If I am connected via LAN (T-based 1000 Mbit Gigabit Ethernet) everything works extremly fast.
Does anybody have a Idea to Solve this Problem? I run Mountain Lion in the latest Version, nothing has changed the System since or before the Error occured.
Thanks....

Camera flash on e63 also wlan connectivity

Can anyone help - I just got a re-conditioned E63 and when flash is needed in dark conditions all I get is a blue image on screen! Tried night mode on/off and white balance - doesn't make any difference.
Just a general query - am totally new to Wlan connections managed to set this up with my home computer, but when tried to connect to a known wlan in Spain just would not connect even thought put in correct password - should i have altered anything else? Not techno minded so plain english replies please!
Cheers

I'm not sure what you mean by hard and soft reset. There's only one reset in Apple terminology. A reset involves pressing and holding both the home and sleep/wake buttons for 10 seconds or so until the Apple logo appears. If that doesn't solve the problem the next thing you can do is restore the OS. A restore would likely correct any software glitch that may have developed preventing the LED to illuminate. Use iTunes to restore your iOS device to factory settings - Apple Support If that fails to fix the problem the next step would be to have the hardware examined by Apple.
Just be aware if you choose the do-it-yourself route as suggested above you'll disqualify yourself from any after warranty Apple support should anything go wrong now or in the future. Similarly a third party insurance company may have you take the phone to a independent phone repair shop which would also disqualify you from any future Apple support. If you decide to take it into Apple to have it diagnosed they'll likely offer you an out of warranty exchange for a fee rather than replace parts. https://www.apple.com/support/iphone/repair/

N8 and WLAN connection properties

Is it possible to show some extra properties/informatio about WLAN connection?
By selecting
Valikko -> Asetukset -> Yhteydet -> Langaton lähiv. (yhdistetty) -> "valinta" -> Tiedot
(freely translated, may not be exact name)
Menu -> Settings -> Connections -> Wireless network (connected) -> "select" -> Details
one sees the name, duration and data amount.
If I go to Connection management (Yhteydenhallinta), I can see more information, e.g. Name, Medium, State, Network, Signal, Encryption, Send power, data amounts.
I would like to know the basic info such as used nameservers etc.. Is there a way to do so? Is there some extra apps (free) to do so?
Any help is much appreciated!
Solved!
Go to Solution.

Try Nokia Connectivity Analyzer from Betalabs - http://betalabs.nokia.com/apps/nokia-connectivity-analyzer. It is able to show you extra information on all your network connection options including WLAN connections.

AcquireConnection method call to the connection manager Excel connection Manager failed

I used VS Studio 2008 (BIDS version 10.50.2500.0) on an WinXp machine (v 5.1.2600 SP3 Build 2600) to create a package that writes multiple query results to different tabbed sheets of a single excel spreadsheet. The package was working just fine and has run
successfully multiple times, but all of a sudden when opening the project, every single Data Flow task with an Excel Connection Manager displayed error icons. Each raises the following error message when attempting to open the Advanced Editor:
SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005 Description: "Unspecified error". Error at DataFlow task name: SSIS error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method
call to the connection manager Excel connection Manager failed with error code 0xC0202009. There may be error messages posted before this with more information on why the Acquire Connection method call failed. Exception from HRESULT: 0Xc020801c (Microsoft.SQlServer.DTSPipelineWrap)
From the time I created the original package (when it worked fine) until now:
1) I have been using the same computer, the same login account and the same permissions.
2) I have been writing to the same (32 bit) 2010 Excel file (which I created) in a folder on my local machine.
3) The filename and location have not changed; a template file is used each time to move and overwrite the previous file. Both are in the same locations.
4) I can independently open the target Excel file and the template Excel files with no errors.
6) The ConnectionString has not changed. The Connnection String I am using is
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Conversion\Conversion\Results_dt01.xlsx;Extended Properties="EXCEL 12.0 XML;HDR=YES;".
7) Run64BitRuntime is set to False.
8) Delay Validation is set to true
9) This is not running under a SQL job
10) There are no child packages being run
I CAN create a NEW Excel Connection Manager, assigning it the exact same target Excel spreadsheet, successfully, but when I attempt to assign it to the Data Flow destination this error occurs:
"Test connection failed because of an error in initializing provider. Unspecified error."
Thinking that the driver might be corrupt, I opened a second SSIS package, which also uses the Excel Connection Manager (same driver) and this package continues to work fine on the same workstation with no errors.
I have searched online for causes of this error for many hours and found nothing that helps me to solve this issue.
Does anyone have any suggestions for me?

Yes, I have verified that the Excel file is not in use or opened by anyone, including me. It has been two months since I opened this particular package, although I have been working with other packages in this project. I just discovered that another
package in the same project has the same problem - all Data Flows that output to an Excel Destination now have the same error icons. This second packages outputs to an entirely different Excel file than in the first package. A summay:
Package #1 has error on every Excel Destination and uses templateA to overwrite fileA and then writes to fileA
Package #2 has error on every Excel Desintation and uses templateB to overwrite fileB and then writes to fileB
Package #3 has no error on any Excel Destination and is linked to multiple files (none are A or B)
Package #1 and #2 are in the same project, but Package #3 is in a separate project .
I will try replacing the Excel files with new ones for Package 1 and 2.

Thats my connection string

You can try an OLEDB provider in that case

5800,Wlan connection appears as 'unknown', however...

Hi to everybody!.
I have an issue with wlan connections. I defined a new access point in wireless connections, and I put it into the 'internet' destination. The access point is saved as WLAN_XX, and works perfectly.
As soon as I disconnect it, and click to find wireless connections, something rare happens. When there is high signal, the connection appears as 'known'. However if there is low signal, appears as 'unknown'. Therefore I have to configure it again as a new connection (retyping the wep password),which as a consecuence, is saved as 'WLAN_X01)'.
I updated the firmware from 31.0.101 to 40.0.005. A saved connection always showed as 'known' (even when i had not enough signal to connect) when i used the old firmware (31.0.101). I don´t know if it´s a new feature or a bug or how it´s solved, someone knows? Thanks.

This is normal. You can delete this access point from the settings and re-save it.

The packet data and wlan connection runs automatia...

guys guys guys i'm having a wiered problem with this rubish E72
well every time i check my log i find that my phone has used packet data connections and wlan connections for small time intervals and small periods while i haven't used the internet for a long time btw i always make sure to exit all app and also make sure to disconnect my email before exiting so packet data signals and wlan signal are not (on)
so that means that the phone just uses internet by it's own self also notice that the time that the phone used the internet was during my sleep time
but it's so weired it has used the packet data for 30 seconds and the wlan fo 1.5 mins by it self ..............is this a virus or that ugly firmware is just full of **bleep**
please check your phones (log) and reply me back
thank you

[SOLVED] Wireless internet connection problem during installation

Hi to everyone!
I ask you a help in activating my wireless connection.
I tried to install from the recent ISO (201208 - via CD)
but I found some problems in activating a wireless connection in the first steps
of the installation guide.
My laptop is a Hp pavilion dv5 1020-el, with an Intel wireless 5100AGN internal interface.
So I did:
1) iwconfig to see my devices and the system detects my wlan0.
2) followed the Wireless_Setup page from wiki to set it
3) used wpa_supplicant and passphrase to set my ESSID name and wpa key.
4) iwconfig then showed wlan0 associated with my ESSID, with Power ON and Encryption OFF.
I could not try a connection via ping command.
Even wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf did not work.
Maybe the problem is with Encryption OFF.
Thanks for your attention!
EDIT:
I solved this way,connecting to an open wireless open network:
1.(from boot) I created a profile in /etc/network.d/ from /etc/network.d/examples
2. started a # netcfg 'my_ESSID'
3. # ping -c 3 www.google.com
All is ok! I can install Arch Linux from my smartphone as a router.
But I couldn't connect to a WPA protected wireless network yet.

Thanks to everyone who responded to my question. The company who provides the wireless internet service to my apartment complex moved the antenna next to my unit and claims he boosted the power. As the saying goes, "The squeaky wheel gets the grease". I complained almost daily to the apartment manager and she, in turn, griped to the provider which eventually led to the "solution" above. Using Skype is still shaky as the person I'm calling isn't always able to make out what I am saying. So, I use Skype only when I REALLY need to make a phone call. Even though none of your suggestions solved my problem, I am still very, very grateful to all of you who tried. Thank you very, very much! -- Matt

J9 wlan connection handling - help needed

I wrote an application which is running on phone and communicates with a server. I can open sockets, and communicate with the server (read/write data on chanel), but after ferw minutes/hours(depend on trafic) the wlan connection between the client and server breakes. The problem is, that after an exception is thrown, I close th connection and try to open a new connection, but can't. It seems, that somewhere in the phone's operatin system the connection is not closed.
My question is , that is there anybody who meet this problem? The second question is that kind of workaround can be used to reconnect to the server?

hi,
have you found a solution? I have nearly the same problem now...
My application runs on windows mobile 6.1 with IBM j9. Connecting to the WLAN inclusive VPN works well on the device, browsing with internet explorer is no problem and if necessary the WLAN and VPN connections are established automatically if needed.
But when I try to invoke a webservice-request from within my java-application the connection isn't established. (Doing the webservice-request while a there is an existing connection everything works fine, e.g. when starting the application right after browsing in internet explorer).
Probably I have to tell the connection manager on wm6 to connect - but how do I implement that?
For .Net I found the following:
- http://msdn.microsoft.com/en-us/library/bb840031.aspx
- http://msdn.microsoft.com/en-us/library/ms849587.aspx
Can anybody give me a hint, please?

No instant Wlan connection when starting up Satellite L650

Hello,
I have had connection problems with my L650 Toshiba for the past couple of months.
I bought my laptop a year ago (October 2010), and everything was working perfectly until April 2011.
The first few months, my computer would connect automatically to the internet once it started up.
Since April 2011, my computer takes about 2 minutes to connect to a wireless internet connection when I start it up, whether it is my home connection or work connection.
Once it does connect, the wireless connection works perfectly.
The problem does not come from a wireless router because it happens with all wireless connections. Furthermore, I have tried updating the drivers for the wireless adapter (Broadcom 802.11n) with no success at all.
I would be grateful if someone could provide possible solutions to the problem.
Thanks in advance.

So what is the problem exactly?
The Wlan connects fine but it takes two minutes until the connection has been established?
Right?
Well, it could be possible that something is running in the OS background and therefore it takes some time until the notebook could connect to the Wlan.
In my case the notebook needs some time to connect to Wlan because the virus scanner and CCleaner run at the startup and scans the HDD and the system.
After that the notebook connects to Wlan.

After Updating Mountain Lion, Mail & Safari keep crashing; WLAN Connection fails

After Updating Mountain Lion, Mail & Safari keep crashing; WLAN Connection fails;
I have updatet Mountain Lion and since then, Mail & Safari keep crashing plus: WLAN Connections keeps on failing from time to time.
My Router has the newest firmware, i am clueless what to do.
I even cannot shut down my mac properly.

Hello you all,
I also had the problem of a disconnecting wifi while my imac was sleeping. I did not have the reconnecting issue after sleep, but the lost connection issue during sleep which made it impossible to reach my imac for things like homesharing, apple tv or remote desktop. I have a late 2012 iMac with a clean ML 10.8.2 on it and wirelessly connected to an apple time capsule (same as an airport extreme). My partner has a mid 2007 iMac, also with an ML 10.8.2 on it.
I tried every single solution I could find on the internet, such as changing the router's security from wpa2 to wpa, changing the MTU from automatic to manual 1453, router reboots, re-installations, re-configurations, keychain clean-ups, everything.
Eventually I solved my problem with these steps and now it works as a charm. I can still find the iMac with the remote app, even after 12 hours of sleep:
My time capsule router is set on automatic MTU and encrypted with WPA2 and I use the 5Ghz network!
1. Cleaned all the wifi passwords in keychain on my iMac
2. Created a new network location in system preferences
3. In this location I deleted the bluetooth pan and bluetooth dun connection.
4. In this location I changed the preferred connection-order to wifi on #1 and ethernet on #2.
5. Restarted my iMac.
Now I still have a connection when it sleeps and I can wake it to low profile using the remote app (homesharing) and everything works fine.
Hope more people wille be helped by this.
