[SOLVED] Lenovo W500 fails to connect wirelessly to home network

Hi Arch community. I can't get the built in wireless adapter to work but I can't seem to figure this out. I did drop the laptop a few days ago from about 70cm, but it is able to scan for access points, so I am assuming that the built in wireless adapter still works.
My laptop is a Lenovo W500 and the router is a Netgear Wireless ADSL Firewall Router DG834G.
On the router I configured it to use this security option:
WPA-PSK+WPA2-PSK - If selected, wireless clients may use either WPA or WPA2. This option is sometimes called "Mixed Mode".

Does this mean it does connect successfully and then I do not understand why it disconnects afterwards?
Many thanks in advance!

Hi everyone, I got it finally after some more headbashing! It turns out I can't run networkmanager along with wpa_supplicant at the same time. I don't understand why though.
Before I happened to install networkmanager along with network-manager-applet via pacman.
# pacman -S network-manager-applet
# pacman -S networkmanager
# systemctl enable NetworkManager
# systemctl start NetworkManager
So I just stopped it
# systemctl disable NetworkManager
# systemctl stop NetworkManager
and then uninstalled it
# pacman -R networkmanager
# pacman -R network-manager-applet
Then wpa_supplicant works! Thanks.

  • Unable to connect wirelessly to home network.

    Unable to connect wirelessly to my home network from my MacBook Pro. My Powerbook G4 is connected wirelessly, no problem. However, the MacBook Pro keeps failing. I have tried rebooting both the modem/router and the MBP without success. I have also tried entering in the WEP code several times without success. Need help troubleshooting this. Thank you.

    Not a problem. I appreciate whatever assistance you can spare.
    I popped an Ethernet cable into the MBP and am downloading the 10.7.5 update. Says it's going to take about an hour. Going to see if that fixes the problem. Seems many Lion users have complained about wireless problems, so it appears I'm not alone.
    As far as the other utilities you describe, I can't find anything that fits that description. I have something called AirPort Utility, but when I launch it, the window contains no columns, just a gray window with a globe and a prompt telling me that no AirPort base Stations have been found and that it's searching for one. I see nothing in my Applications or Utilities called Connection Doctor.
    Here's hoping the 10.7.5 update remedies the problem. If not, I fear I might have to keep my MBP "tethered" via an Ethernet cable until I can find a fix for this.
    Thanks again for your help.

  • Can i use new TC to connect wirelessly to home network and plug my tv into the time capsule for internet connectivity?

    My new tv needs to plug into an ethernet port for internet connectivity. 
    I'm hoping it can plug into my TC however my TC is wirelessly connected to my current home network... how can i get this to work?
    TC version A1470 (i think, brand new)
    Many thanks.
    Ben

    If the TC is connected to a wireless network provided by another Apple router, then the TC extends the network by default, and the Ethernet ports are enabled on the TC.
    If the TC is connected to a third party network wirelessly, then it must have been setup to "join" the wireless network. When the TC is set up this way, the TC becomes a wireless hard drive and nothing more. The Ethernet ports are not enabled when the TC "joins" a wireless network.
    So, a logical first troubleshooting step would be to confirm "how" the TC is currently set up. To do that.....assuming that you are using a current or recent version of AirPort Utility on your Mac.......
    Open AirPort Utility
    Click on the TC icon, then click Edit in the smaller window
    Click the Wireless tab at the top of the window
    Check the setting for Network Mode and report on that

  • Macbook won't connect wirelessly on home network

    Hey guys,
    I see that a lot of you are having the same issue I am. I have a Macbook that I got the summer of 2008. Up until Thursday, it would connect wirelessly to my E-wire router and network just fine. Then it quit. Later that night, I went up to school for a class, and it connected just fine to the wireless network up there, but will not connect wirelessly to my home network. I have since gotten a new router (Netgear) and reconfigured everything (again), including security and all updates. Airport shows that I am connected to my network, and I can load web pages when I am plugged into the router via ethernet cable (as I am now) but when I try to launch Mozilla or Safari wirelessly, I get the "Server cannot be found" error message.
    I am connected to my network, I have tried shutting off Airport and restarting it, as well as quitting my browser and reopening it, and rebooting my Macbook all together. And I also went in and manually entered my IP address, which is what allowed me to connect to the network via ethernet cable in the first place.
    Any theories why my Macbook (which is newer) won't connect wirelessly whereas my roommates older Macbook doesn't have any issue connecting wirelessly from right next to me? And I know that it's not an issue of too many people trying to be on the network at once, since it's just the two of us at most, and I'm the only one here right now.
    Any thoughts or suggestions would be appreciated.

    Is your router a model that supports a/b/g/n? If you turn off N will it work? If your N is setup at 40MHz slots it may not work as well. Can you take your wireless router somewhere else for testing? I assume you might have some issue where you are at with your Mac and that router. When you open Apple Menu/About this Mac/More Info../Network/Airport does it show your network there? From a working machine can you see your Mac from your router web interface? FYI if your router was an Apple product(Airport Express or Airport Extreme/Time Capsule) you could see all your wireless clients via the Airport Utility, even signal strength and connection speed...

  • IPhone 5 has failed to connect to my home Wi-Fi

    my iPhone 5 has failed to connect to my home Wi-Fi and its seems am the only one experiencing this problem at home because my housemates iPhone 4 and Blackberrys get the wifi nice and clear. yet i have connected to this wifi with iphone5 before.

    Try resetting your wireless router and modem.
    Disconnect the wireless router from the power source followed by disconnecting the modem from the power source. Wait 5 minutes followed by reconnecting the modem to the power source and allowing the modem to completely reset before re-connecting the wireless router to the power source and allowing the router to completely reset with the modem.

  • TS1398 ipad suddenly failing to connect to a wifi network

    My ipad refuses to connect to our home network, and yet it was doing so perfectly for several days. The laptop still recognizes and connects to the wifi perfectly, I've tried all the tips and suggestions provided on the apple help site, including resetting networks on the ipad, etc etc. No luck. Any usggestions out there?

    Have you tried power cycling the router?
    Does the iPad connect to other Wi-Fi networks?
    You could also try to update the router or make sure it is setup in a way that is most compatible with the ipad.

  • Airport wont connect on my home network when its password protected but..

    Airport wont connect to my home network when its password protected. It will connect to my network if i go into my linksys router and set the network to "not password protected". If i put on the security and choose a pass phrase it always says connection failed when i try to connect to the network. anyone got any suggestions on what to try ?
    ps and yes i am putting in the password right

    Hi Nickerjones
    When you enter your password for the Linksys router, is it generating a separate code phrase? By this, I mean if you enter "password", the Linksys converts this to a code that might look something like "ju457re76en7pq" for example. The code is generated based on an algorithm that Linksys uses for their products and should be visible in the set up page. Sorry, I haven't used Linksys for several years so I can't remember all the details.
    Other manufacturers use different algorithms for their products, so if you entered "password" on an Apple product, it would likely convert the phrase to a different code, which the Linksys would not recognize. If you can locate the actual code that the Linksys generates when you enter your password and use that same exact code when you enter the password for your wireless on Airport, you may have your problem solved.

  • Today my ipad will not connect to my home network

    new ipad air, set it up fine and used it with my home network 2 days ago. Charged it last night and now will niot let me connect to my home network. I did reboot

    Some things to try first:
    1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    4. Go into your router security settings and change from WEP to WPA with AES.
    5.  Renew IP Address: (especially if you are droping internet connection)
        •    Launch Settings app
        •    Tap on Wi-Fi
        •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
        •    In the window that opens, tap on the Renew Lease button

    Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
    Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
    You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

  • Tecra A10 - Refurbished - unable to get it connected to my home network

    I just got this Tecra A10-104 refurbished Laptop...before I take it back I am asking here just in case theres something I have missed as I am unable to get it connected to my home network.
    I am running a Belkin Wireless Router that has 2 main PC's directly connected (LAN), and another PC wirelessly connected.
    This is my router: http://www.belkin.com/uk/support/article/?lid=enu&pid=F5D8233uk4&aid=9238&scid=0
    All PC's working fine and connected.
    Now I'm trying to setup this laptop to connect.
    I uninstalled the Vista Business and ussed the XP Pro Product Recovery disc that came with the Tecra.
    My WiFi card is: Intel(R) Wireless WiFi Link 5100 (Driver Date: 27/04/2008 - Driver Version: 12.0.0.73)
    It sees the network but no matter what i try just won't connect.
    What I have done so far (read before suggesting stuff I have already tried):
    Reconfigured routers WPS to Shared Key system.
    Made sure the wireless adapter has settings set to 20/40hz (auto)
    Restarted router, cable modem & laptop several times
    Wireless button on side of Laptop is ON.
    FN + F8 to enable WIFI (ON) BLUETOOTH (OFF)
    Added wireless network to Auto Connect settings along with SSID and passcode end encryption method.
    Clicked connect when network appears in network viewer dialogue and retyped passcode.
    Not working.
    I should add the Laptop has no problems connecting via its Gigabit LAN port.
    Anything else I'm missing?
    Thanks in advance.
    EDIT: Dual post removed.

    UPDATE:
    The next thing I tried was to reinstall Vista Business from recovery disc to see if this suffered from the same problem.
    The wireless connection worked fine on Vista and, despite the updates that I was being offered, worked without needing to update any drivers.
    This made me think...so the issue is probably XP DRIVER related.
    What I have done now is backup all the driver updates I was told to download by TEMPRO (BIOS & wireless manager updates included).
    I think part of the problem is that TEMPRO only works in Vista (not XP) so you are not informed of any updates that may be required if you downgrade to XP straight after purchase (which is what I did).

    I figured I didn't really phrase the question correctly...
    I was just wondering why there are so many on the list and the ones that don't have a padlock icon next to them worry me...
    I would like to block/disable them.....
    The wireless radio picks up and displays all WiFi signals that are openly transmitted.  That is to show you the networks available to join.  Those that do not have the padlock are unsecure networks, which should not bother you as long as you do not attach to them.  Their being open has no affect on your security.
    You cannot completely and permanently block their being listed.  Just ignore them and don't attach to any unkown networks.

  • Connecting to existing home network via Airport Express

    I had my Macbook Pro connected to our home router which allowed me access to our home network and the internet. On this network we had connected both my MBP and my flatmates PC (which is connected directly to the router via network cable).
    Through this configuration i was able to both access the internet AND access files on the PC. I have recently purchased and airport express to eliminate the need for the network cord. Since setting up the AE i have been able to connect to the internet no problem by creating a wireless network and using all the automatic settings, however in the process i have lost my ability to connect to the home network and my flatmates computer. In fact, under "networks" in finder the home network has disappeared. Also in network prefences i am getting a warning saying "The cable for Ethernet is not plugged in".
    Is anyone able to tell me what im doing wrong?
    thanks ....
    Message was edited by: seysearles

    The problem is that the AirPort Express (AX) is creating a subnet.
    To prevent that, configure the AX to act as a bridge (so that it is NOT sharing a single IP address).

    There is no way to find out your IP address from a remote location. Its possible that your home hub has locked up, or your broadband line has failed.
    Unless you can get someone to check at home, there is nothing you can do.
    The home hub does not normally respond to a ping request anyway.
    There are some useful help pages here, for BT Broadband customers only, on my personal website.

  • Can't even connect to my home network.

    Title says it all, bought a 64gig iPad wifi today...little did i know tons of users are having wifi problems...my problem doesnt seem to fit the others though. Most of what i've read people can connect for a bit, and after being in sleep mode then it has problems. I can't even connect to my home network. Works fine with my ipod Touch, laptop, etc. I dont have any form of security set up on my router what so ever. I plan on buying a new router soon (for reasons other than this iPad crap.) I'd really like to see some kind of resolution to this problem before i need to do that though.
    I tried all that i could out of the trouble shooting stuff. nothing worked. I even tried setting up a static IP for it. What else can be done? i really dont want to have to return it since its such a nice piece of tech.

    Umm... one of the questions that's been asked is whether his iPad will connect anywhere else, If it will, the issues is between the iPad and the particular configuration he has at home. If not, the issue is with the iPad.
    Since we don't have an answer to that question yet, your inference that anyone is telling him to "phone ahead to every business or hotel he plans on visiting to request that they replace their "clunky old router" " is unjustified and unhelpful.
    Please, continuously blaming every ipad wifi issue on the same router that happily works with every other device is getting old. What standards does iPad support that these clunky old routers do not?
    Since, as you've said in another post, you're experienced in the ways of the internet, you will know that it's quite common for new kit to have problems connecting to old kit.
