Connected to Wireless Network, Not Connected to Internet...

Hi All
I recently had my NVIDIA graphics card replaced as it freaked right out the other day.
I took my MacBook Pro home yesterday and everything was perfect. It connected to my wireless network @ home as normal, and was functional all night.
I have come to work today, and it automatically joined up with the network here. Only problem is, that whilst it connects to the network here, and obtains an IP address as well, as soon as I try to connect to the internet, it says that I am not connected to the internet!!!
Now the finer details:
* I have reset EVERYTHING. Routers, Modems, Computers etc
* All firmware is still the same as it was pre-nvidia fix up.
* Distance is not a problem, I am sitting next to the wireless router.
* An ethernet cable from the router to my computer ALLOWS access to the internet
* My Iphone can connect wirelessly to the same network and browse the internet.
* A windows PC can connect wirelessly to the same network and browse the net.
* I can see that it is connected to the router AND given an IP address.
Please help!!!

I had the same problem. I sent my MBP to get a Logic Board/Nvidia fix and when it came back I could no longer connect to networks using DHCP. I have to manually put in my IP, Subnet, etc. for every network I join.
Randomly about a week in I had some pop-up window show up asking me to allow incoming network connections for something and when i clicked on it I was able to us DHCP again. Just tonight it stopped working and I am once again in the position where i have to manually input IP info, etc.
Super Frustrating

  • Can't connect to wireless network but connects if I move it 1 meter

    Hi all,
    I've had my 27" iMac Intel Core 2 Duo for over 3 months now with no issues, but suddenly over the weekend I can no longer connect to my network.
    Sometimes I can see my network listed (but the signal is now very weak when it used to be very strong) and when I try to connect I get a "Connection Timeout" error. Othertimes I can't even see my network.
    If I move my whole mac about 1 meter "closer" to the router (it sits downstairs, my mac upstairs) it connects fine. But as soon as I put it back on my desk, where it has been sitting for the past 3 months, the connection drops out or it can't find the network. (I can't leave it "closer" to the router, as that would mean I'm sitting on the floor right in my room doorway...)
    All other PC's, laptops, my MacBook and iPhone all connect fine. In the MacBooks case, it connects fine in exactly the same spot as where my mac had been sitting for the past 3 months.
    I'm using a Belkin N150 wireless router which is supposed to have a range of 300m (my house is definitely not that big!) and using a WPA2 Personal password security setting. As I said above, no issue before this past weekend (same router, same settings).
    I have tried the following:
    - restarting router, modem, computer (in various orders) to no avail
    - deleting the system configuration folder, re-starting, etc.
    Just wondering if there's something I'm missing? Or whether or not it's to do with the wider issue of connecting that people seem to have? I thought it may be different since I can connect if it sits somewhere else...
    Any help wold be appreciated since my support has run out!
    Thanks in advance!

    Yeah I've tried moving it but unfortunately I'm a bit constrained as to how far I can move it (aprox 20cms each way). There are lots of ethernet cables plugged in and they all run behind what is, a very solid, very big desk/shelving thing.
    However, the position of the router hasn't changed in the past 3 months.
    I've also tried disconnecting the cordless phone which sits in the same room and moving any extra cables around the router to no avail. But none of these things are new either.

  • Can not connect to wireless networks with ipad 2

    My ipad used to connect to the wireless net at home and in public areas.
    Now all by the sudden it can't "see"  the network.
    Message: " could not connect to wireless network"
    I have tried "everything" also on different networks,
    except resetting the modem.
    My iPhone works, as do all my other computers.
    Modem is Zyxel P2812

    Additional things to try.
    Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

  • TS1398 wi-fi network not providing an internet connection

    wi-fi network not providing an internet connection
    I have done everything there is to do. Reset my netgear reset password etc and still no connection.  I use to have connection but got a new I pad and can not set it up.

    You may not really be connected to your WiFi network.
    Your router may not have given your iPad a valid IP address. Go to Settings > Wifi > your network name and touch the "i" to the right to see the network details. If the IP address shown starts with 169 or is blank then your router didn't provide an IP address and you won't be able to access the Internet.
    Sometimes the fix can be as simple as restarting your router (remove power for 30 seconds and restart). Do not reset your router. Next, reset network settings on your iPad (Settings > General > Reset > Reset Network Settings) and then attempt to connect. In other cases it might be necessary to update the router's firmware with the latest from the manufacturer's support web pages.
    If you need more help please give more details on your network, i.e., your router make, model and version, the wifi security being used (WEP, WPA, WPA2), etc.

  • MacBook automaticlly connects to wireless network, but not mine

    At home when I start my MacBook, it sometimes connects to the neighbors wireless network (not protected at all) rather than to ours. It does that all by itself, without me doing anything. Can I tell my computer to only connect to our network, or at least to as for a confirm if it wants to connect somewhere else?

    Hello Hans-Conrad Zur Loye. Welcome to the Apple Discussions!
    Try the following:
    1. Delete Preferred Network(s)
    o System Preferences > Network > AirPort > Configure
    o In the "By default, join:" pull-down menu, select "Preferred networks"
    o Delete the network(s) you regularly use from the list
    2. Delete AirPort Keychain Entries
    o Launch the "Keychain Access" application located in Applications/Utilties.
    o Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
    o Restart, or log out then back in.
    3. Add Preferred Network(s)
    o System Preferences > Network > AirPort > Configure
    o In the "By default, join:" pull-down menu, select "Preferred networks"
    o Add the preferred network(s) using the "+" button.
    o Restart or log out then back in.

  • Two Issues: Cannot connect to wireless networks; Cannot load certain sites

    Hey everybody,
    I have a MacBook Pro 15".
    In just the past week, I've stumbled upon two sudden problems with my network/internet connectivity.
    First, I can no longer connect to wireless networks, be it an infrastructure point or computer-to-computer ad-hoc networks. I'm not really sure why. I installed the latest AirPort Update (4.2.3, according to System Profiler). I also recently installed both iStumbler and KisMac v.21. When I started having issues, I thought that maybe one of these two programs might be the culprit, so I uninstalled both of them but I still have the same problem.
    Second, I've had issues with not being able to connect to certain websites. I use both Safari and BonEcho as my browsers. The specific sites seem random:
    www.weffriddles.com
    www.macrumors.com
    images.google.com
    sports.yahoo.com
    finance.yahoo.com
    to list a few.
    If you need any diagnostic information, please let me know.
    Thanks in advance for any advice/help you can provide!

    MacBook Pro   Mac OS X (10.4.9)   browsers: Safari, BonEcho/ Airport Driver Version: 4.2.3

    If you are trying to connect to a third-party router using WPA or WEP, there is a good chance that your Airport card was broken by Apple's 2007-02 Airport Update. There is no fix, and for many of us, our Macbooks and Macbook Pros are useless for wireless connections until Apple fixes the issue. At this point, Apple seems to be denying that there even is an issue, so we may all be in for a long wait indeed.

  • AOL Broadband, will connect to laptop, but not connect to internet explorer. WRT54GS v.6

    I can connect to my wireless network via my laptop, but not to internet explorer. We have changed every setting imaginable and re-set the modem, router many times. We Ip configed, did ping tests, installed and re-installed the card in the laptop. Done all this 4 times with the tech support from Linksys. Finally, I realized it must the wireless router and/or modem configuration. (The laptop works on every other network in town except ours, and has not security settings enabled).
    I have been on customer service calls for 2 weeks, with AOL and linksys and nothing seems to be helping me. I have 2 wireless routers (thought the first was bad, so bought another brand new), and just had a brand new modem installed. Basically, I have brand new equipment.
    The laptop has no security settings and connect to any wireless network in town. It finds the connection to my WRT54GS v.6, but will not connect via internet explorer.
    I want to uninstall and re-install the router. How do I uninstall the router? (I have instruction for re-installation). Also AOL rep told me, to make sure I configure the router to a certain port range. Any ideas as to how to do this?
    Anyone have problems with AOL high speed and linksys router? Has the high speed cable cord coming out of the wall, not ethernet or DSL.
    We have changed the settings in http://192.168.1.1 till I am blue in the face. None of the channels worked, security didn't work, adding the ip address manually to the laptop didn't work. I am getting no error messages. Am trying to get this wireless modem working because I need it. Should have come to this forum first!

    hi..if you want to uninstall the router...the only thing you need to do is hold the reset button down for 30 seconds...
    i m a bit confused here as to why the ISP techs asked you to forward ports on the router...port forwarding is needed for a specific application or a device that is behind the router....
    the mentioned ports are for AOL messenger ( AIM )....and has nothing to do with the modem...anyways , let us work out together on this issue...carry out the steps i mention and you can revert back with the results and your success rate...
    1) connect the computer to the modem and check what ip address you have on the computer ??
    2) go to start -> control panel -> network connections ->
     let me know what other icons you have besides Local Area Connection and Wireless Network Connection..
    3)connect the computer to the router and the router to the modem...
    access the router using http://192.168.1.1 .. let the internet connection type be on DHCP....check the ip address on the status page of the router ui...
    4) if it is 0.0.0.0 , go to setup tab and go to mac address clone subtab , enable it and hit clone..save the settings and do a power cycle...
    5) check whether you have the ip address...if you have the same ip as coming off of the modem..u should be online and if still 0.0.0.0 , then select PPPoE for the internet connection type and enter the username and password...check whether the ip address comes up....if still negative, ensure that the modem is in bridge mode...
    6)if the ip address comes up as 192.168.1.x , change the local ip add of the router to 192.168.2.1 and do a power cycle..
    let me know for any help !!!

  • Need HELP! connecting to wireless network; IP Address problems!

    I am trying to connect to wireless networks using the AirPort built into my MacBook Pro. There are two specific networks I am trying to connect to, both are WEP protected. I know the passwords and can get into each of them but I cannot connect to the internet, which is the main reason for connecting to them in the first place! When I go into System Preferences and click on Network, I see that next to AirPort it says I am connected to the network but may not be able to connect to the internet because my computer has a Self Assigned IP address. I assume this means my computer is not receiving an IP address from the network. I am set on full auto with DHCP. So what's wrong? Please Help!!!

    That indicates that the MacBook Pro did not successfully communicate with the DHCP server on the network. Do those networks have access control (MAC address filtering) enabled? If so, the best solution is to reconfigure the base station so that this feature is disabled. This adds no real security since MAC addresses are easily discovered and cloned.
    If you can't disable access control, you will need to add the MAC address of the wireless interface of your MacBook Pro to the list of allowed clients.

  • [SOLVED] Cannot connect to wireless networks any more after update

    Hello,
    I updated my system some days ago and, after that, I can't connect to wireless networks any more.
    My network card is ath9k and I'm currently using wicd.
    When I try to connect to my wireless network, I get "Veryfing AP association" message, then it fails to connect.
    Here's the dmesg output :

    This particular line caught my attention: " wlan0: de-authenticating from 00:1c:10:57:47:17 by local choice (reason=3)". So I searched for it (without the MAC address) on the internet and found several solutions for it, involving wpa_supplicant, dhcpcd, IPv6 (disable it on /etc/sysctl.d/40-ipv6.conf) and card power management (operation not supported, don't have option on BIOS), but none of them worked for me.

    It makes the code more readable and - in case of longer listings - more convenient to scroll through.
    Okay, put code tag now. Here's the whole log since Feb, 24th. This was the day I started having problems.

  • Brand new macbook pro cannot connect to wireless networks

    The first time I called apple tech, they thought it was a problem with my internet provider. I've called 4 times now, and I'm still getting the runaround.
    I have an old (2001) G4 sitting right next to my macbook pro which can see numerous wireless networks and connect to them all. A strong connection at that. However, my brand new (refurbished) Macbook Pro Intel etc,.... supposedly best computer ever made, . . . . can see the same wireless networks but has never been able to connect. As a student, I saved for a year to buy this notebook so I could work at cafe's & study with my friends. My friends with PC's can all connect to these wireless networks. My friends with older, less expensive notebooks can connect no problem. I have never been able to connect. Bought this peice of junk 2 1/2 months ago - only because I didn't want to be stuck at home anymore with my desktop. Stupid me to trust apple.
    I wish I could get my $ back, but I'm now being told that it's 30 days too late. Before they told me it was a minor thing and some software update could fix it. I did as told. downloaded and installed their 10.4.8 thingy - deleted all the keychain stuff - nothing. same peice of junk.
    Now they are telling me to go back to the genius bar where folks are just rude to me and tell me they can't help me becuase I bought a "refurbished" model that didn't even save me $25. What do you know.
    Anyone having problems like this? Anyone out there who can help me?

    Okay,
    I apologie for calling it a peice of junk. I know you all probably worship this machine. I'm just really frustrated. I noticed that this is a very common problem - though most of the posts identical to mine have dissapeared from apple.com - this well known defect is all over other discussion boards and websites like macdefect, etc,....
    So, can any of you tech gods help me with this very well known, common problem that I haven't been able to fix with 10.4.8 upgrade?
    Thanks for your time and assistance,

  • Can't connect to wireless network in XP under bootcamp

    Hey there,
    I'm hoping that someone here can provide some help. I've got XP sp2 running 'fine' in Bootcamp - 10.6.3 iMac 27 i7. The only thing that I can't get working is the wireless connection. I can't for the life of me figure out how I am supposed to get XP to connect to my wireless network, and consequently no internet access.
    From what I've read I'm supposed to go to Network Connections and choose 'New Wireless Connection' but the problem I have is that I don't see 'New Wireless Connection' there anywhere. I have installed the extra drivers from my Snow Leopard disc but this problem persists.
    Have I missed something? Can anyone offer any advice on how I can get this working?
    Thanks very much in advance!

    Hi,
    have a look here http://support.microsoft.com/?scid=kb%3Ben-us%3B870702&x=10&y=12 for possible solutions.
    Might be a problems with a hidden SSID (Service Set Identifier).
    Hope it helps

  • Hp C4580 printer won't connect to wireless network, but see network is available.

    I've sat through quite a few of the threads here with regard to photsmart C4580 printer not connecting to wireless network.
    My issues started with a cartridge issue, which I resolved with a new cartridge, but only after trying out different solution offered on HP forum.
    Now printer won't connect to my network which it has been connected to for over 2 years with no issues. The wireless network is working perfectly fine and I even printed out a HP photosmart C4500 series connectivity status and in this report printer can see the network I need to connect to.
    I've tried downloading various programs from Scan doctor to complete install of all HP programs and even tried installing printer from Windows 7 "add a printer", but none can see this printer.
    lastly I was hoping trying to locate IP address for printer which looks like it may help, but report says IP Address "not applicable".
    I believe printer, wireless network and PC are working correctly, this there a way to switch printer to online so it can be seen.
    Help would be great.

    Hello there! Welcome to the forums @Cushionman ,
    I noticed your post about the issues you are having with connecting the printer to your network. I am wanting to offer you my suggestion that might help you out!
    Click this link and then choose Windows 7, and "Solution two: Manually resolve the issue", and follow the steps from there: The Printer is Not Found During Wireless Network Installation in Windows
    Let me know the results

    Then after a reboot, I wouldn't be able to connect to wireless network anymore.
    I tried "netcfg Wireless_Archer(my wireless profile's name)" as usual, it replied:
    [root@mzws log]# netcfg Wireless_Archer
    :: Wireless_Archer up [BUSY]
    > WPA Authentication/Association Failed
    [FAIL]
    Next I tried to bing the network up manually. I followed the "Wireless Setup" and "WPA supplicant" wiki, then I get a timed out problem:

    I tried the "iwconfig wlan0 channel auto", but that didn't work. Here's the output of "lspci | grep -i net":

    03:00.0 Network controller: Intel Corporation WiFi Link 1000 Series
    So what's the problem here? I searched the forum and google, and it seemed that I connected to a wrong router(for sometimes I only one "carrier lost" then "timed out"), but how was that happened? Things worked quite well before the upgrading as well as in my Windows environment.
    Any reply would be appreciated! Thanks in advance!

    Thanks Proofrific, but I believe it's not, for the DHCP server is a built-in module in my wireless router.
    I am now able to connect to my wireless network now. And it seems to be a little kernel bug as I discovered a thread(sorry but I forgot which one) in the forum discussing a similar problem.... Somebody in that post suggested a work-around to change the channel, as their default setting is channel 13 or 12.
    I tried and it did work! Just simply open your router's setting page and then change the channel from auto to 3(in my case), and netcfg worked well now. For the manual configuration, I suppose the "iwconfig wlan0 channel 3" should be issued.
    Thanks everyone in the forum for providing their solutions!
