Macbook pro connected to network but no internet connection

Hey all,
i have a Macbook pro, running on OS X 10.6.8,
i made a software update, where a java update was made, an HP printer update, a Itunes ipdate and a Macbook Pro SMC firmware update 1.6.
Since then, i cant connect to the internet.
I ran network diagnostics and it says "your connection appears to be working correctly".
Same if i plug in the Lan-cable to my laptop.
Network diagnostics says that my internet is running correctly, but no browser or any other program can connect to the internet.
tried it at 2 different location (home and work) and nothing works. Other laptops have internet connection through the same router and wifi.
restarted router and wifi, did not help
restarted wifiAirport multiple times, wont help,
restarted Laptop multiple times, wont help.
renewed DHCP, and IP adress, i get a new ip adress, and it says im connected but it wont work.
any other ideas?

That doesn't mean anything. You can't telnet to google. lol
The ping you did above shows you that Internet access and DNS is working fine. If it wasn't, you wouldn't be able to get replies. This means that the problem is with your browser. Open up Safari and hit Safari/Reset Safari under it's menu. See if that works to solve your issue. If it doesn't, then it's a plugin or something else (maybe Proxy changes, etc.) which could be causing this. One option you have to test is if the reset doesn't fix it, install another browser (you'll need to download the dmg via another PC and install it on the mac from a memory stick or something) and see if a 3rd party browser works.

Connected to network, but no internet connection

Just returned from a one week trip to CA with my macBook. Prior to the trip everything regarding a connection to the internet worked fine... I have an Airport Extreme network set up at home. For the first five days of my trip, everything worked fine as well. Connected to several different open networks (offered by hotels and Bed & Breakfasts (B&Bs). Then suddenly I could not get an internet connection with any browser (Safari, Firefox, Flock). At one particular B&B it worked flawlessly one evening, then the next morning at the same B&B, no internet. Yet I was connected OK to the open network. Moved on to another city, a different hotel and network, same problem. I was connected to the network, but no internet connection. In Safari, the blue bar would get as far as the http:, then it would hang there. Now having returned home to my Airport Extreme network, everything seems to be working fine again in all browsers. Any idea what I may have encountered for those two days? I have another trip planned in the near future, and would hate to have this happen again.

I'm sorry but I'm not posting to answer your problem but just to say that I have a very similar issue when connected to my home network through either wireless or ethernet- connection is erratic and pages hang despite showing an excellent signal strength. I have a divided drive and have windows installed on my Macbook. I have no problems on the windows side. My friends who have ipods and iphones have similar problems connecting to my home network. I have no problems connecting wirelessly to any other network that I've tried. This is a real shame as I want to use Mac software but end up in Windows all the time. Any light anyone can shed on this would be very welcome.

Why is my macbook pro running so slow and losing internet connection?

Why is my Macbook Pro downloading so slowly and losing internet connection frequently?

Write off the MS stuff as indicators for now--starting with Office 2008, they developed very long launch times. The time to launch 2008 on my old 1.25Ghz G4 and my MBP 2.2G are virtually the same. Even document opens/saves are slow compared to Office 2004 and earlier.
1) You have adequate hard drive space so that eliminates one of the usual suspects.
2) Check for runaway background processes. Quit all running user applications so the computer is at normal idle. Find Activity Monitor in Applications > Utilities and launch it. If you've not run it before, change the "Show" pulldown at the top of the AM window from its default of "User Processes" to "All Processes." There is a column for "%CPU." Click that column header to sort by CPU usage. Watch the processes "bubble" for about a minute to get a better picture of the usage.
If any process is using more than about 25 percent of the CPU cycles while the computer is idling, post the names of the processes and we can see if they can be eliminated. My MBP shows nothing using more that about 5 percent on any given test run as long as I close all my user apps.
3) If you have never done any sort of maintenance procedures, taht can slow you down. Simply restarting the computer a few times a week clear a lot of temporary files. You also may wish to review this article on the Mac OSX periodic maintenance scripts, which, if run, also do a lot of cleanup:
http://thexlab.com/faqs/maintscripts.html
There are other useful articles on file maintenance associated with the one. Here's the index:
http://thexlab.com/faqs/faqs.html
Check out articles with "Maintain" and "Tuning" in the titles.
4) Use Disk Utility to check the SMART Status of your hard drive. A failing drive can make things slow before it makes things stop.

Connected to network but can't connect to internet using wireless

Hi, I just installed a Linksys WRT 45G and can connect my pc and my laptop to it and use the internet fine when I use ethernet cable, but if I try to use my laptop wirelessly I can't connect to the internet. It says that I am connected to my network and that strength signal is excellent but no internet connection. I have that bluetooth button on the front of the laptop turned on. The laptop is a Toshiba Satellite with Centrino. I was told that I don't need to buy a wireless card as the Centrino already does this. Thanks in advance for your help.

I think you can try to update the firmware of the router, to check if that stops connection dropping. To update the firmware of router try this: 1. Go to www.linksys.com/download and select correct model number and version number. Download the firmware and save it on your computer. 2. Check the file it sould be firmware image file like .bin etc. If it is a compressed zip file extract it to get firmware image file. 3. Open setup page of router by typing http://192.168.1.1 in browser’s address bar, and typing password as "admin" and no user name. 4. Go to administartion tab there 5. Go to fimware update sub-tab there 6. Browse for the firmware image file and click update 7. when update completes turn off modem & router. 8. After 2 minutes turn on modem and after 2 more minutes turn on router. To get network key, connect your computer to one of the four ports on router using ethernet cable. 1. Open setup page of router by typing http://192.168.1.1 in browser’s address bar, and typing password as "admin" and no user name. Use your password if you have changed it earlier 2. Go to wireless tab. 3. Go to wireless security sub-tab 4. If security mode is wpa or wpa2 note down passphrase/shared key, if security mode is WEP note down wep key number 1. This will be your network key Well you need to input all the wireless settings of your wireless network on Wii. To get these settings: 1. Open setup page of router by typing http://192.168.1.1 in browser’s address bar, and typing password as "admin" and no user name. 2. Goto wireless tab. Here you will get the wireless network name/SSID. Here make sure wireless SSID broadcast is enabled. 3. Now goto wireless security sub-tab and here you will get the security mode and the security key. If security type is WPA note passphrase/shared key, and if its WEP note down wep encryption level and key 1 from listed 4 keys

Attempting to Connect to Network Shuts down Internet Connection

I am setting up a G4 400 MgH Mac with AGP graphics to get on a network of computers. This originally came from a college where it was on a network running OSX and OS9.1, and I have added a 100 GB hard drive on which I installed OX10.4, and upgraded to OS9.2.2.
It is very odd, as when I try to connect to the network through the ethernet connection in starting up in OS9.2.2, it will connect to the other computers and to the internet without problems, and does not affect the internet connection. However, when I start up in OSX, all the other computers on the network lose their internet connection immediately when this computer boots up into OSX. I can, however, connect to the other computers on the network, but cannot connect to the internet. I am puzzled as to what resource in OSX must be damaged to cause such a problem. I have tried reloading Tiger, and have used Disk Warrior, but the problem is the same.
I would welcome any thoughts on how to fix this so we can get this added to the graphics network at our school.
G4/1GHz, 7600 w/G3/500 MHz , G4/733 MHz Server Mac OS X (10.4.7)

Only thing I can think of is that the AGP in OSX must have a Network setting that is grabbing an already used IP, or perhaps even the IP of the Router, or perhaps is set to Share the Internet connection.
I'd first off uncheck all ports in Network Port Configurations, reboot, for a try check on Ethernet in Port congigs again.
2nd, I'd try giving the AGP a Manual IP above the possible range handed out by the router.
3rd, I'd make a new User and see if the same thing happens.
If that doesn't work, I'd try trashing these and rebooting...

Macbook Pro connected to network but won't connect to internet

My Macbook Pro is connected to the wireless network we have with a full signal strength. However, it will not connect to the internet unless I plug the computer directly into the router with an ethernet cord. Additionally, I can connect wirelessly without any problems at hot spots or other houses.
Anyone have a simple fix? I've already reset Safari. I've restarted routers and modems. I don't know what else I can do.
Any help would be greatly appreciated. This happens a little too often.

I think you trouble shot your problem. Get a new router.

MacBook Pro sees wireless networks but cannot join any. Connection timeout error

I have a MacBook Pro here that sees all wireless networks but cannot join any. It gives a connection timeout error with every one.
Internet access via ethernet cable works just fine.

It's not uncommon for you to "see" a great many networks, dozens even, yet you not be able to connect to any of them even if they are "open" (no lock icon). There may be a number of reasons for that, such as they're too weak for a reliable connection, or the router may limit connections to only specified devices.
There is only one way to achieve a reliable network connection, and that's for you to connect to your own wireless router. Even that doesn't work if its signal is too weak or if there are many competing wireless networks in your area.
If it's your own AirPort Base Station you're trying to use but can't, the latter could be the reason. The only way to mitigate the effects of wireless interference is to use 802.11n and 5 GHz whenever practicable. Even today you may only find one or two 5 GHz networks being used in an otherwise "crowded" area.

MacBook Pro says connected via Airport but no internet connection at all.

I have a strange problem. My MacBook pro 13" 2009 is no longer connecting to a wireless network it was previously able to get Internet through over wifi. I have not used the wifi here for quite a while 3-4 weeks so the recent update may have something to do with it, but this laptop has the most picky network cards out of all macs I have owned, refusing to connect to many routers. The strange thing was, it used to work on this one, and it's doesn't anymore while no settings have been changed. It works over Ethernet fine. My iPad and iPhone work perfectly on the same wireless. Even the windows laptop works on the network without a hitch.
Looking in the settings, it does not even obtain an address for the router, so how could it possibly be connected to it? And it gives itself the weird ip address of 192.168.1.77? Also, I am using a WEP key, but as I said no settings have changed since I last successfully used it.

The router is a Thomson TG585 a few months old not sure on firmware.

Macbook connected to network but no internet

Hello,
I am having a very strange and concerning internet issue with the Macbook in my household. It can't access the internet even when connected to a wireless network. I know this is not a network issue because a Macbook pro, iphone, and ipod touch all connect to my network at home and can access the internet just fine. Also, the Macbook was unable to access the internet when connected to the school network while my iphone and other computers could.
The problem started suddenly last Monday. Prior to that the internet had been working both at home and at school. It appears to be connect to the network because there are full airport bars and a check mark next to the network (in both locations) but it can't find the airport in the Airport Utility (while at home since the school doesn't use airport). Additionally, it wouldn't connect to the internet directly through the ethernet port either when I plugged it directly into the cable modem.
In the System preferences it has a Self Assigned IP. The preferences are the same as they were when it was working and nothing looks wrong. On Thursday I tried the fix someone posted on this forum of deleting the network from the preferred networks and then adding it again and it worked at home for a day but it still wouldn't work at school and yesterday it stopped working again at home. When I tried to the fix again it didn't work. Also, I've tried repairing permissions twice and that hasn't done any good either. Additionally, it happens under both users on the computer and the test user I created.
Any help would be appreciated.

Macbook Pro connected to wifi, but no internet connection

Hi,
Just bought new Macbook Pro yesterday with Mountain Lion OS. When back home, trying to connect internet, unfortunately safari would always says "No internet connection". I try very hard on getting it up creating new connection on MBP but it still give the same result. So I think it should be related my router setting. The current wifi setting for my TP-Link router is WPA2-PSK, AES, channel 11 with secured password. When I changed it to NO security, supprisingly the connection is now OK and I can browse internet through Safari. The problem is I have to get it back to WPA2 security setting since my home internet is now open to my neighbourhood and of course it shouldn't be shared all around you. Anybody can tell how the router setting should work with MBP, with details on security type, AES or TKIP,CHANNEL?

That doesn't mean anything. You can't telnet to google. lol

Airport will connect to network but not internet

Hi,
My MacBook air started out working beautifully on my wireless network-high download speeds, solid connection, etc... After about six hours of operation however, it has stopped being able to find the internet consistently, no matter what wireless network I try. I use a NetGear wireless hub in my room, and my laptop is able to consistently find and connect to the network (the hub is only about 3 feet away) but it cannot connect to the internet. Under network settings I get the message "Airport has a self-assigned IP address and may not be able to connect to the internet" or "Airport cannot connect to the internet." I know that the internet is working, because the network works fine for my MB Pro, iPhone, TiVo, and xBox 360. In fact, the MBA is occassionally able to find the internet and get an IP address. Sometimes this IP address allows me to load web pages extremely slow and sometimes I cannot even find google. The problem extends beyond my one network, however, as I have difficulty connecting to other wireless networks. I am on a college campus and sometimes can connect to the campus WiFi, but it again frequently connects without being able to figure out an IP address. Some help would be great.

I have a similar issue. Mine does the same thing, but only if in a specific area. If I'm sitting on my recliner with the Air on my lap, then it will connect, but I can't get to any sites. The browser just stalls.
If I move to the table that's 3 feet away from me, then the internet connects without any problems.
It could be a reception issue with me, or something. I don't know. At first it connected at very high speeds. That was before 10.5.2.
I don't know if the Leopard Update has anything to do with it, since my iMac doesn't have this problem at all. And that has an N card also.
I hope Apple is looking into this wireless issues.

Slate 21 Pro - Obtains IP address but no Internet connectivity

Hi all,
I have a Slate 21 Pro with no internet connectivity at home. The device obtains an IP address via DHCP on either wired or wireless networks, but when attempting to browse or access internet-based resources, it simply times out. I've also tried manual IP address assignment with no success. If I take the tablet to a local wi-fi cafe, it connects fine, but I can't get it to work at home. My ISP is Baja Broadband, a 50MB/5MB cable connection Local network details below:
* Arris T822G cable modem - ISP-provided, no routing or firewall capability, just a plain old modem
* Cisco/Linksys E3000 wi-fi router - internal network gets NAT'ed here. no filtering, nothing fancy
* Netgear 24-port managed gigabit switch
I've tried bypassing the internal network and connecting the Slate 21 Pro directly to the cable modem via wired Ethernet. Same problem - it obtains an IP address (a public IP in this case) but will not connect to any internet sites. HP sent me a replacement unit which displays the exact same problem. Both units work fine at the wi-fi cafe.
(OS is Android 4.3 Jelly Bean. I could take the unit to the wi-fi cafe and see if there's any OTA updates available if anyone thinks that might help.)
I'm a network engineer with 25 years IT experience. My home network is a mature network with no known problems. Connected to this network and functioning perfectly are: 2 iPhones, a Roku box, an LG smart TV, 2 Macs, 4 Windows PCs. Previously had 2 HP Touch tablets which were also fine. Home visitors are able to connect their phones and tablets to our wi-fi with no problems. It's *just* the Slate 21 Pro which is misbehaving.
I'm stumped. Any ideas?
Thanks,
Steve
This question was solved.
View Solution.

UPDATE: This is resolved. I discovered I was able to access Internet sites by IP address but not by hostname. There was something wonky with the ISP-provided DNS server. Once I substituted a different DNS server in the IP config, it works.
Weird!

Can connect to network but not internet

In trying to secure my wireless network, I connect to my network, but I am unable to get to the internet with the wireless security enabled. I have no problems connecting over the wireless when I disable the security.
I have a linksys broadband router.
I use a Mac book with intel chip that I am trying to connect wirelessly. I also have an older imac that is connected directly to the router that I was trying to share files.
I was trying to setup WEP- I know very little about network protection. I have had a router for a couple of years and when I was trying to set it up so I could share iles I realized it was not protected. At the linksys website I had several options, but experienced the same problem (I had a strong network connection, but unable to connect to the internet) no matter which encryption option I chose.
The error meeaage says that is unable to connect
Thanks

Hi.
I assume that you have a linksys router plugged into an airport express.
First off, seeing as you have a macbook you should use WPA2 instead of WEP as it is more secure. You can select this option in the airport admin utility on the main page. Make up a password enter it and click apply. The express will update. Then, when you select your network from the airport icon on the top of your screen it will prompt you to choose the type of security on the network (which will be WPA2 and after selecting this it will then propmt you to enter the password. Enter the password again (checking the keychain box as well) and this should be it.

Computer is connected to network but can't connect to internet (Safari and Chrome), e-mail, App Store, ect.

My Macbook is connected to Wi-fi (four bars) but can't connect to the internet or any other services that requires internet. Other devices in my house have easily connected to the internet but every time I open Chrome it says: "This webpage is not available". What do I do?

Restart your internet modem and router and your Mac then try Safari etc.
If that doesn't help, try this DNS server ..
Open System Preferences > Network > Advanced > DNS
Click + and type:
208.67.222.222
Click + again and do the same.
208.67.220.220
Click OK.
Try a browser.
if that doesn't help, check the firewall. System Preferences > Security & Privacy > Firewall > Firewall Options
