• ubuntu wifi disconnection & frustratingly connects to unavailable wifi

  - by ashishsony

  Hi, i have already posted this here: here This has happened before with ubuntu 9.1 Beta2 build too that my wifi disconnects if im idle for 5 minutes... so i cant leave my lappy to download anything... i have to keep on continuously using it.. as soon i leave it idle for abt 5 minutes... wifi disconnects... and the pop up asking for password for wifi pops up...with the password already filled in... i just click on connect and it connects again... so whats the use of asking the password if the pre filled in pass works correctly... and this is happening on ubuntu 10.04 Beta2 too... and the workaround is that just open any menu like the applications menu in the taskbar and keep it open... under this state the ubuntu idleness never activates and so the wifi gets never disconnected... this has been confirmed by me many times.. this seems to be repeating again and again... i dont know why... and the second thing i want to report is that there is no way to report this bug from ubuntu... the launchpad.net talks of going through bug reporting process which is done against a definite package... now how does a user know which package would be causing this error?? there should be a more clear process of reporting such bugs to ubuntu team... thirdly the apport utility that reports crashing apps is totally uselss on 10.04 beta 2... as it collests information and reports that i cant submit the report because i dont have 100 other packages... without updating which i cant submit the report.... surely on a beta build there would be packages continuously being updated... so no system would be reported as fully updated... and so no practical apport reporting is possible?? please address these issues... really frustrating all this ... im a big fan of ubuntu but these things really bug me... and just to add fourthly... the suspend/hibernate feature has never ever worked on my toshiba m70-113 laptop... on any ubuntu version... always have to hard reboot after putting into suspend/hibernate mode.. on windows this has never been the case... why cant ubuntu beat windows in such cases too?? i would really like to see this soon... most importantly, when the router switches off... the wifi signals go off... then why the hell ubuntu keeps on connecting to that very wifi like hell and when doesnt connect shows the prompt to manually connect... with the wifi key already filled in... whats the use of saving the key when it has to ask the question from me either to connect or not?? and if its isnt available... just wait when its available.. i have only option to cancel and if i cancel it wont auto-connect!! what the heck?? one can see in the image that it says "authentication required by wireless network" when there isnt any.. as router has gone down!!

• How to switch off wifi on startup or from the console

  - by mit

  I have installed ubuntu 10.04 on a laptop. Wifi is switched on by default on startup. I can disable it rightclicking the network manager icon in the gnome bar. How can I set it to have wifi switched off as default? Alternatively, how can I switch off wifi on the console? I tried already the rfkill command but it does not list any devices and it does not switch off wifi, I tried different parameters. This is a standard install of the Ubuntu 10.04 i386 Desktop Live CD on an IBM T40 Laptop. EDIT A: This is the output of some rfkill commands on my system, and it does not affect the wifi of the laptop: $ rfkill --help Usage: rfkill [options] command Options: --version show version (0.4) Commands: help event list [IDENTIFIER] block IDENTIFIER unblock IDENTIFIER where IDENTIFIER is the index no. of an rfkill switch or one of: <idx> all wifi wlan bluetooth uwb ultrawideband wimax wwan gps fm $ rfkill list $ rfkill list wifi $ rfkill list all $ rfkill list wlan $ sudo rfkill list all $ sudo rfkill block all $ sudo rfkill block wlan $ sudo rfkill block wifi $ EDIT B: Now I found out that sudo ifconfig eth1 down turns it off. And I can turn it on through the gnome network applet again. But the applet does not reflect the change from the commandline, it stills believes wifi is switched on. I have to switch it off and on again on the applet to switch it on again, when I switched it off from the console. Is there a better way? This is what the syslog looks like when I switch wireless off and on again from the network manager: NetworkManager: <info> (eth1): device state change: 3 -> 2 (reason 0) NetworkManager: <info> (eth1): deactivating device (reason: 0). NetworkManager: <info> Policy set '24' (eth0) as default for routing and DNS.

• HP dv2700 series, Wifi not working in Ubuntu 12.10, Wifi Button always disabled

  - by Chicoscience

  I have a HP dv2745se laptop. I always had Ubuntu with the Native Windows Vista and Wifi worked fine. Suddenly my Ubuntu wouldn't load anymore, I tried fixing it for a week and eventually I formatted its partition and just installed Ubuntu 12.10 This laptop has a Wifi switch that works fine in Vista disabling / enabling the wireless connection. HP Wireless Assistant in Windows say Wireless is on. However, whenever I log in Ubuntu the Wifi button is always orange (disabled) and Wireless never works. I had this problem once when I had Ubuntu 12.04 and I fixed it by verifying in Windows that the Wireless Assistant showed the Wireless LAN in "On" mode. However, the same does not work now. I've seen some possible solutions that involve updating the firmware with apt-get. There comes my 2nd problem, my network adapter card is not working and thus I have no internet at all. Any suggestions? Thanks!

  - by giri

  I am trying to get wifi direct working on a laptop with ubuntu 12.04 When I type the command 'iw list' it doesn't show P2P-client or P2P-go under 'supported interface modes.From http://wireless.kernel.org/en/users/Documentation/iw/replace-iwconfig I found that 'iwconfig' was replaced with 'iw'.Does it mean that my hardware doesn't have support for wifi-direct or is it just the software(drivers) issue? If is it just sofware issue please help me to find the right drivers which support wifi-direct. Here is the info about my ethernet controller from the output of 'lspci' 02:00.0 Ethernet controller: Atheros Communication Inc.

• Android Scan for Wifi networks

  - by Nils

  Hello, I'm trying to scan for wireless networks and found this helpful source on the net. Unfortunately it's not working and I have no idea why. My problem is that I can't wait 10 minutes for the result - I need them within a few seconds and thought about setting the boolean variable waiting on false as soon as I get a result.... well, it runs forever ... looks like nothing is received. Any idea ?

• Android Stream Data Over Wifi?

  - by Neb

  Im trying to make an app for android that will stream the data of the accelerometer to be used as a game controller on my pc over a local wifi connection. Is it possible to make some kind of wifi stream of the accelerometer values in the android app and then make the pc somehow 'read' this stream? Or would it just be better for the pc to make endless calls to the phone getting the newest accelerometer values from a local android server? It would also have to send commands from the phone such as 'button1 pressed', 'button1 released'.

• How to detect/list rogue computers connected to a WIFI network without access to the Wifi Router interface? [migrated]

  - by JJarava

  This is what I believe to be an interesting challenge :) A relative (that leaves a bit too far to go there in person) is complaining that their WIFI/Internet network performance has gone down abysmally lately. She'd like to know if some of the neighbors are using her wifi network to access the internet but she's not too technically savvy. I know that the best way to prevent issues would be to change the Router password, but it's a bit of a PITA having to re-configure all wifi devices... and if the uninvited guest broke the password once, they can do it again... Her wifi router/internet connection is provided by the telco, and remotely managed so she can log-on to their telco account's page and remotely change the router's Wifi password, but doesn't have access to the router status page/config/etc unless she opts out of the telco's remote support and mainteinance service... So, how could she check if there are guests in the wifi with this restrictions and in the most "point and click way"? In this case I'd probably use nmap to look for other devices in the network, but I'm not sure if that's the easiest way to do it. I'm not a wifi expert, so I don't know if there are any wifi-scanning utils that can tell us who's talking to the router... Lastly, she's a Windows user as I guess that'll influence the choice of tools available Any suggestions more than welcome Regards!

• Wifi connection frequently dropping in hotspots and university campus, home Wifi works fine.

  - by Olivier Lalonde

  For some reason, my Wifi connection frequently drops everywhere except at home. I didn't have this problem with Windows 7 so I guess it's not a hardware problem. My best guess so far is that my connection timeout is very low so if my connection isn't able to reach the router after a few second, the connection drops. Is that likely to be the problem? If so, how could I fix this? Otherwise, what would be an alternative cause for this strange behavior?

• Slow wifi from Windows Server 2003 virtualized in XenServer

  - by John Clayton

  I'm a brand spanking new user of OS X, coming from a lifetime of Windows use. I've been setting up my new Macbook Pro and have run into a very unusual problem. Over wifi, I am unable to copy files to or from my Windows Home Server. The problem seems to exist only over wifi, and only to WHS. Here are the details of my setup: 2010 Macbook Pro (Core i7), OS X 10.6.3 Windows Home Server PP3 (virtualized in XenServer 5.5) Windows 7 Ultimate x64 desktop Windows 7 Ultimate x64 in Boot Camp D-Link DIR-655 wireless N router Here is what I've done to narrow down the problem: Files copy fine from WHS to OS X when using gigabit ethernet Files copy fine from desktop to OS X when using gigabit ethernet Files fail to copy from WHS to OS X when using wifi (error -51) Files copy fine from desktop to OS X when using wifi Files copy fine from WHS to Boot Camp when using wifi Files copy fine from desktop to Boot Camp when using wifi From what I can tell, it seems to be some sort of issue between OS X and WHS, but I can't for the life of me see what would be different between shares on WHS and my desktop. They are both connected using smb://ADDRESS (I've tried both by IP and name). I can browse the shares on the WHS, but copying to OS X fails. I originally found the issue while installing VS2010 off an ISO from WHS, mounted to a Windows 7 VM using VMware Fusion. During the installation the VM was unusable - even the clock got behind the host be about 8 minutes. Once I plugged in the ethernet and disabled the wifi things picked up and finished quickly. The Fusion 3.1 RC is the only I think of that I installed that may have messed with the wifi driver. I've also tried resetting the wifi router, and have changed it from being G & N to N-only. Under Boot Camp I get similar speeds as my wife's N laptop. Any ideas? Thanks! Update: The issue has been further narrowed down to Windows Server 2003, which Windows Home Server is based on, running in XenServer with the XenServer tools installed.

• Use case for sharing wifi over bluetooth?

  - by Andrew Koester

  What is the use case for applications like PDAnet or Android Wifi Tether supporting sharing wifi over Bluetooth? A friend and I were discussing this, and neither of us could figure out why you would need to redistribute wifi over a Bluetooth connection. In most cases, said receiving device would already have wifi. Any clues would be appreciated.

• How to see who is using my wifi

  - by Bakhtiyor

  Dear all. Such a question. I have WiFi router at home and would like to know if there is any way to know who is connected to my WiFi network and using it. My WiFi network is password protected but still there could be chances that neighbors crack it and could use my WiFi for free. For this reason I would like to know is there is any tool to inspect the log of WiFi router in order to know which computers are connecting to it. Thanks a lot beforehand.

• Can't connect to public WiFi with MacBookPro at coffee shops and libraries

  - by Nathan Bowers

  The Problem: I can't connect to public, unencrypted WiFi at my local public library or Peets Coffee. My Setup: Late 2006 MacBookPro running 10.5.8. I have Parallels installed. It's supposed to work like this: 1) Connect to their unencrypted WiFi network 2) Open a browser which redirects you to their "enter password/agree to terms" page. 3) Browse normally. I can connect to the WiFi network, but when I try to authenticate I always get stuck in a redirect loop. It's been like this for a while. Even before I upgraded to 10.5.8. I never have trouble with encrypted networks or regular open WiFi. What I've tried: Disabling Parallels connections in Network Prefs. Superstition: somehow Parallels installed something in the network stack that's messing me up. Pinging the IP address of the WiFi node I'm connected to. I can ping it, it's there, but I still get stuck in this authentication redirect loop. Tried different browsers, tried different cookie and security settings. Even tried IE under Parallels. No dice. Tried flushing DNS cache. Asked library and coffee employees for help. It didn't go well. My Question: Anybody else have this problem? What should I be looking for?

• WiFi N Gigabit Router

  - by SLaks

  I'm looking for a WiFi N Gigabit router. I'll be using an iPod Touch 2G and a 2009 17" MacBook Pro over WiFi, and I need at least 4 gigabit ethernet ports plus a WAN port. What do people recommend? In particular, are there any compatibility issues between different WiFi N drafts that would limit the speed of the MacBook, and is it worth getting dual-band?

• Using ADSL Modem/WiFi Router to share existing network wirelessly

  - by joshhunt

  At my uni we have a wired Ethernet connection in our dorms. However, I want to share this connection with my macbook using wifi (so I don't have to be constantly tethered). I am looking at using my DSL G064T ADSL modem/WiFi router as a wifi repeater for the uni network. Is this possible? How would I go about doing this? I understand that it would be possible using a normal Wifi router (seeing as it has an ethernet 'in' port where it would get the external connection from.), so is it just not possible using the router I have? If i need to buy another one, which one would you recommend?

• Leaving my wifi open for the world

  - by Thomaschaaf

  For my home I want to be a nice neighbor actually I have let my wifi open for the past maybe 6 or 7 years. I know that WEP, etc can be cracked within a couple of minutes but my neighbors son who works in IT told his mom and she told me that I am doing bad things and you know the story.. Do you think it's okay to leave your wifi open to the public? I live in a suburb with a tiny street and about 8 houses in reach of my wifi. I have a 16k DSL line so if some one joins me for a couple hours I would probably not notice. I would love your thoughts on whether I should encrypt my wifi or not.

• Windows 7 wifi reports "no network access" and "no internet access" but connects in fedora

  - by rick2047

  I am running windows 7 home basic (64bit) on a Acer 5742G laptop with Atheos wifi adapter in it. Yesterday, I hiberneted my computer as I always do and up untill then the wifi was working fine. When I booted my computer up again today I started having a strange problem: It detects my wifi but after connecting to it, it keeps on oscillating between states of no network access and no internet access. I can't connect to anything (the internet or my router). I tried to reset my internet protocol stack using this fixit file. I also tried to uninstall and reinstall my network driver. Neither helped. I am using the same laptop's fedora installation right now and the wifi is working perfectly fine. Please help. Edit To add additional details, I have Microsoft Security essentials as my antivirus software and I haven't messed with the firewall or the router configurations.

• Win XP cannot connect (or see) my wifi network, but can see others

  - by Jorre

  since yesterday I have a strange wifi problem with my pc. I have a wireless linksys router setup that worked fine for many months, now since yesterday my pc won't connect to the wifi signal anymore. The strange thing is, my macbook pro still connects fine. SSID is broadcasting, but my windows XP doens't see it, I have all signal modes set to "auto". Windows XP sees all my neighbours wifi networks, so the wifi card isn't broken or anything. Any idea what can be wrong here?

  I'm currently having a Problem with my msi GT70 laptop. my laptop is running windows 8 and yesterday it requested a Restart to Update. after the Restart and the update I tried to surf the net through google chrome, the WiFi connection is perfect but the page I tried to access is not loading at all, after a while it shows failure to load page. I disabled and reenabled the WiFi chip through the device manager but still no internet connection. I uninstalled and reinstalled the drivers, still no internet. I updated the Driver of the wifi, still no internet, I even went to Wifi configuration and tried to change the DNS and reset it back to automatically, still no Luck.. I'm really lost I don't know what to do, I don't want to go deep and play with Laptop DNA "aka: registry file" and screw things up. I really appreciate any help in this matter. thanks in advance. Note: I tried to access many pages but no luck. I even tried Firefox, Opera, even ie still no luck. The internet is working fine on my tablet and cellphone, except for the Laptop.
