MacBook Air unable to access internet

My MacBook Air is showing full strength on wifi but I cannot access internet.  I have also tried to connect via Ethernet cable and iPhone hotspot and the problem persists.  Please help

Power Cycle
Power off the router. Unplug it from the wall. Wait for few  minutes.
Connect the router back to to the wall.
Power the router back on. Wait  until all lights are lit properly. It will take a while.
Restart the computer.
Start up in Safe Mode.

  • My macbook air is not getting internet connection through our home wifi It was working fine yesterday until I took the Air out of the house and used it on another wifi connection.

    My macbook air is not getting internet connection through our home wifi.  It was working fine yesterday until I took the Air out of the house and used it on another wifi connection.  One question is how to delete some of the networks that I don't use.  Would too many networks cause the internet connection to fail?
    Thanks.

    Would too many networks cause the internet connection to fail?
    It shouldn't but sometimes deleting the list of networks actually does solve the problem you are describing. Have you turned WiFi off and then back on on the computer?

  • MacBook Air loses connection to internet but not LAN

    Hi, I am using a MacBook Air 11" (mid-2012) running OS X Mavericks (10.9.3). I'm connecting to my home LAN via WiFi connection to a TP-Link 300M Wireless router that is setup as a switch (per instructions here http://www.tp-link.com/en/article/?faqid=417), which in turn is connected via wire (ethernet-over-power) to a Technicolor cable modem/router provided by my ISP (UPC in the Netherlands; I can look up the model number of the router if needed, but it's two floors down right now and doesn't strike me that this is the cause of the problem).
    I have a problem that my MacBook Air intermittently loses connectivity to the internet for extended periods (minutes) even though (a) the MacBook Air maintains full connectivity to my LAN at the same time through WiFi and (b) other computers connected to the cable modem/router maintain their connection to the internet while my MacBook Air has lost its connection.
    My test to see where the breakdown is occurring is to have four terminal windows up and running ping processes:
    1) ping to 192.168.0.1 (my router) - this always stays live, with essentially no lost packets
    2) ping to an external address (I'm using 74.125.136.94, a google.nl address) - this is my main test for access to the internet and where I see ping failures (I'm also testing with pings to other sites when the problem is occurring to ensure it's not something on the remote end).
    3) ping to 192.168.0.13, which is a Synology NAS attached via ethernet cable to my main cable modem/router - this always stays live, with essentially no lost packets.
    4) a login to the Synology NAS, where I am also running a continual ping to 74.125.136.94, and this external ping does NOT fail when the one from my MacBook Air does, it stays live with essentially no lost packets.
    The problem will usually correct itself after 1-3 minutes (though the time is not consistent), and also gets corrected if I turn the MacBook Air's WiFi off and on again.
    Any suggestions for what I can do to stop this problem?
    Thanks

    No. If connected to WiFI served by Technicolor, the problem does not occur (even if the other AP is connected to the network).
    >     b. can the Technicolor be replaced easily by an Airport Express/Extreme, to repeat this test?
    Unfortunately, Technicolor in router mode is required by my ISP.

    Yes.

    Yes. A Windows machine and several iOS mobile devices work flawlesly for me.
    > 4. If the MBA has a wired connection to the Technicolor, does the problem still exist?
    No. The problem occurs only if connected through additional AP.

    Not yet. I will not have a chance to do it for the next few days though :/

  • Why won't my macbook air connect to the internet?

    I recently arrived at my relatives house and connected to their guest internet via password. I opened network preferences, selected the network, and it connected. Then when I went to google chrome and safari, I was sent to a page where a login password was required. I entered this password and surfed the internet until mid day. Then this evening I went to log on to the internet and my macbook air wouldn't bring up the log in page like it had earlier this morning and yesterday evening. My iPod touch connects just fine, and so do the windows computers in the house. There is a three-device limit for the guest internet, but currently there is only one computer on it. I tried restarting my macbook several times, I deleted the account from the list of frequently accessed wifi spots, but nothing seems to work. Help please! And nothing too technical, I'm not really too computer savvy. Thanks.

    I recently had a similar problem.  I tried many solutions that others propsed.
    My particular solution, I "looked" into my Westell router and found its IP address. Seeing the other 5 devices (all were working on the internet), I saw how the ending number of the address identified the particular device on the router. I went to the System Preferences on the MacBook Air, opened up Network, chose Advanced and went to the tab TCP/IP and then in the Configure IPv4 address pull down used the manual DHCP and entered a new number that was 12 higher than another computer. 
    Example 192.168.200.1 was router, another computer was 192.168.200.68 and I gave the Air .80 as the last number.  It worked!
    I don't know what will happen when I return to my usual home network where it was working as well as on others.
    Best of luck to all who have this problem.

  • Macbook air unable to join wifi network

    I have a brand new MacBook Air and am new to Macs, but have a very good understanding of PCs. I constantly have to reenter our wireless security code for Wi-fi.  Now I am receiving a message that says "the computer was unable to join the wi-fi network you selected".  What am I doing wrong?

    After a 30 minute phone call with Support, nothing worked still! In the end he suggested changing the channel of the wireless router/modem.  I tried to do this (after research online on my imac) and then lost all internet connection. The router/moden no longer worked at all!  Then had to call the support line for the router; spent another hour or so trying things, but to no avail. In the end have had to buy a new modern modem router (Belkin Dual band N+ PLAY N600 DB) and so far ......................it's working!  But we only bought it this morning. Will report back another day with an update!

  • Unable to Access Internet Despite Adapter Showing "Connected".

    Hi, I have a Lenovo "G"-Series notebook, Type 4446-38U which has suddenly stopped allowing me to access my internet connections.  The PC is only about a month old.  It is running XP Professional. 
    I have three connection options:  1) dial-up (using an onboard HDAudio Soft Data Fax Modem with Smart CP); 2) ethernet or Local Area Connection (using an onboard Broadcom Netlink Fast Ethernet); and 3) wireless (using an onboard Intel WiFi Link 5100 AGN) -- none of these components are showing that they have conflicts/problems in the System Properties/Device Manager. 
    At my home, which is located in a rural area where I can only get dial-up, I tried checking my e-mail last week (with Mozilla Thunderbird), but received an error notice stating that the e-mail server could not be found; it was the same issue, when I tried to get Norton virus updates (Internet Security 2009), XP updates on the Microsoft website (using Microsoft Updates with Internet Explorer), and simply accessing the web (using Mozilla Firefox) -- i.e., "Server Not Found."  The odd thing is that I can not only hear the connection being made by the modem, but can also see that the device is 'Connected', when I check the connection in Control Panel/Network Connections.  The following day at my office, I checked the other connection options (ethernet & WiFi), and found that I had the same problem -- i.e., they were shown as "Connected" in Control Panel/Network Connections, but I was unable to access anything on the web (e.g., e-mail, Google, virus/Microsoft updates, etc.).  It's as if there is something blocking the internet connection to these programmes/utilities. 
    When I ran the Microsoft Networking Troubleshooter ('Diagnose Network Configuration & Run Automated Networking Tests), all the Network Adapters were shown as having passed.  Ditto, when I ran the "Test a TCP/IP Configuration Using the Ping Command" -- pinging 127.0.0.1, the results showed 4 packets sent and 4 received.
    I spent several hours on the phone with Lenovo Tech Support to no avail, and their instruction that I uninstall Norton Internet Security made no difference either.  When they instructed me to open a Command Prompt and ping 192.168.1.1, the results showed that there were 4 packets sent and 4 received.  When I was instructed to ping the IP Address for the wireless adapter, the results showed 4 packets send and 4 received.  When I was instructed to ping www.google.com, the results showed that the ping request could not find the host www.google.com.  Lenovo Tech Support stated that there was nothing further they could do, and that I needed to use a utility to set everything back to factory specs (i.e., have a utility programme erase everything on the hard drive and reinstall XP ... and even then I was told that there was no guarantee that would fix things, meaning that the PC would then have to be sent into their repair depot).  Before I do this, I was hoping that someone here might know as to what's going on with my connection problems and how it could be fixed, without having to erase everything.
    I would appreciate any insight or advice anyone might have.  Thanks so much!
    ~ Jack

    I did do a complete uninstall of Norton (i.e., didn't save any of the settings), but that didn't resolve the connection problem.  I also turned off Microsoft's firewall as well, once Norton was uninstalled (it had been turned off, when Norton was installed, and once Norton was uninstalled, MS firewall defaulted back to an on/active status).
    I also forgot to mention in my initial description of the problem and actions taken thus far to try and correct it, that I additionally tried the "ping" procedure described in paragraph five above in Windows Safe Mode with Networking, but was still unable to connect to the internet.

  • Unable to access Internet using a Mobile Network

    Hello friends
    I recently updated my SE Xperia mini pro 17i (2011 model) to ICS, initially there were some issues and I had to re-update it to finally get authentic interface of ICS. Even after the successful update I am unable to use the mobile network to access Internet, the only way  is to use a Wifi instead. Can somebody please help me out with this issue?
    Karan

    The first thing I would advise doing is contacting your current network provider and have them send you through the relevant internet settings.

  • Macbook air keeps disconnecting from internet when going to sleep mode

    New macbook air keeps losing Internet connection when going into sleep mode. Have tried deleting and re adding network and adding DNS 8.8.8.8 still is disconnecting.
    Also, since Lion update 2 days ago Internet is very sluggish
    HELPPPPPP!!!

    You're not the only one.  See here:

    The current fix is to turn off sleep mode or use an Ethernet cable.

  • Macbook Air unable to restart after a "complete restart attempt"

    Hi,
    I wanted to get my Macbook Air cleaner to work easier this Summer. So I pressed : Command-R while restarting, and deleted the partition called "Macintosh HD". I'd already done it before, so I wasn't frightened at all. I turned the computer off again, and restarted it while pressing Command-R a second time. The fact is, it showed me exactly what I wanted to : The "livebox list". But my livebox wasn't in it, so, I restarted the computer after waiting a few minutes.
    When I pressed Command-R again, it showed me the Earth, turning, and a message saying it is actually looking for an update on Apple's server, but it may take time. After 2 seconds, the Earth stopped her rotation, got a big exclamation point on her face, and had written under her : "apple.com/support - 2006F".
    I looked for 4 hours, but nothing could help my Macbook to download Mavericks again.
    Thank you,
    Paul.
    NB : Sorry for this poor english D:

    Try this.  I am assuming your MBA came with Lion (10.7) or later.
    Boot the MBA withe the OPTION+COMMAND+R keys.
    This should result in a display with a revolving globe.
    This will connect you to the Apple servers and will determine what the original OSX was for your MBA.
    Follow the installation instructions.
    You will need a solid Internet connection.
    Ciao.

  • Ipad is connected to the wifi but unable to access internet or receive mail.

    Recently set up new broadband connection. Wifi set up and iphone, computer all able to connect to wifi and internet. Ipad recognises old networks and able to connect for wifi access, but for this new connection I am able to connect with the ipad but it does not seem to be able to receive or transmit any information, hence I am unable to access any internet, update any apps or check my email. Can anyone help? I've tried rebooting the system, forgetting the network and shutting the ipad off, all to no avail!

    I've rebooted the router, I've made the ipad forget previous settings, rebooted the ipad, called the useless talktalk technical help. I have used this ipad previously with a previous talktalk connection. I'm not sure why this time I can't connect - perhaps its the security setting on the new router that isn't competible with the ipad? I'm using a D-link DSL-3680 router if that helps
