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...

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.

Connecting two networks with two internet connections

Hi All
The situation is this. Two firms situated next door to each other and linked by their businesses and by their family ties, wish to connect their two networks together. They both have internet connections. The reason is for security, in the event of one internet going down they can use the other one.
As I see it, we could use a wireless bridge/repeater to connect the two ethernets together, turn off DHCP in both networks, and manually configure the IP addresses on one network to say 192.168.1.1 to 192.168.1.100 and set the gateway as the router address in that network, again manually allocated. Then on the other network set the scope to 192.168.1.101 to 192.168.1.200 with the router on that network set in this range.
In the event of failure of one internet connection, it would just require the gateway to be changed for those pcs to access the router on the other network. I know of a little program which would do that automatically.
Would this work? If so which Linksys equipment would I need to bridge the two networks. I know some equipment will do the bridging and allow wireless clients to connect, so that would be useful, I know it slows it down by half, but this might be acceptable.
Will there be other problems rearing their ugly heads which I haven't considered.
The networks are not large, so manual IP configuration is not a problem.
Thanks

I presume both networks are using wireless connections. If you can see your neighbour's network on your computer and vice versa, all you need is the passphrase to connect. You may have to disable filter mac address in your router.

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.

"Network disabled because Internet connection is slow"

I have both a Samsung Galaxy S3 and a new Samsung Tab 3. After a recent software upgrade, I was having connectivity issues to wireless routers. The message I got when connecting to a secure wireless network was "Network disabled because Internet connection is slow". I determined that I had no issues with either my phone or tablet on either an unsecure router (WiFi hotspot), or with any older router that broadcast WPA2 personal with either aes OR tkip security. I do have a problem with connecting to any new router that broadcasts BOTH aes and tkip at the same time. When I change the routers under my control to broadcast only aes or tkip, then I can immediately connect both my phone and tablet to the router. There are obviously a lot of routers over which I have no control, so this needs to be fixed. I am pretty sure that there is a problem with the latest Android software upgrade in this regard

I am having the same problem with my Galaxy 3S since the upgrade. Have searched for settings, etc. but haven't found anything I can control. My home network is getting 54.4 down and 5.7 up! Have had this issue nearly everywhere I am connected.
I think it needs a fix - noticed today that Verizon has doubled my DATA for free. May need it if this continues.

Up and Down Internet Connection

Recently my MacBook is having up and down internet connection. I'm using the new Aiport Extreme base station which is connected to my cable modem. By up and down I mean, the connection seems to go in and out.
My Airport signal status is full bars, so it seems to see the base station. It is like the radio signal or whatever gets tangled and drops connection. I have completely reset the base station and started fresh. I've unplugged the modem and base station and gone through all the basic troubleshooting steps.
My wife has a PowerBook G4 and she can surf with no hiccups, while my machine stalls. One thing I have done to keep a solid connection is to connect iTunes to an internet radio station. It seems like the stream keeps the connection without dropping?
Any ideas on what is going on? Is my internal airport card bad or are is there something else going wrong? Any help or insight is appreciated.
Thanks.

Try…
1) Resetting PRAM…

2) Setting your Airport to connect to "Preferred networks" rather than Automatic (done in System Preferences > Network > Airport > Airport)
3) Make sure your home network is at the top of your Preferred networks list
4) Failing those delete your wireless network profile, apply the change and readd your profile

Hi there can anyone help. I am connected to the internet by ethernet but my connection keeps timing out and my network diagnostics shows all green and network connection ok but still no internet connection. the other wireless laptop in my flat works well.

Hi there can anyone help. I am connected to the Internet by Ethernet but my connection keeps timing out and my network diagnostics shows all green and network connection ok but still no Internet connection. the other wireless laptop in my flat works well. Could the other wireless laptops being used in my flat be affecting my connection. what can I do to get connected, keep connected. Thanks for any ideas out there.

My network connected for a few hours then went back to timing out. I have not changed anything. However there four additional laptop users in my family who do not seem to be having any problems using their wireless connection. Could their film and music downloads be causing the timing out of my connection and if so is there a way I could prioritizes my computer or limit their use?

MBP shuts down when connecting to power

Since a week or two, my MacBookPro from early 2011 shuts down when connecting the magsafe to power. Also when starting up again it will start up fine and fast from battery, but I need to hold the power button for several seconds when connected to power.
Another problem I had earlier as well is CPU (kernel task) of over 90%, which I now see clearly, only occurs when connected to power. I used to solve this problem by putting the MBP to sleep, but now, when put to sleep, it will shut down.
When on battery, I have no CPU problem and can put machine to sleep without a problem.
I recently started uploading everything to dropbox, and activate caffeine to make sure it will keep uploading. My computer will run for days on power combined with caffeine, but is as slow as **** because of a >90% CPU.
The battery has had a notification for maybe a year, that it needed service, so today I finally bought and installed a new battery, but the problem is not solved. Is this software or could it be my magsafe adapter? Thanks for you help.

It sounds like a problem with the power management inside your MBP. I suggest you call Apple to make an appointment at your local Apple store for them to check it out for you.

How can i connect to a wifi network with no internet connection?

I used to be able to connect my Z10 to a wifi network even when the network had no Internet connectivity when i got my phone in Feb. 2013 (10.0) However ever since the 10.1 update this has stopped working. I cannot connect to my wifi network when there is no Internet connection. I cannot play videos / music from my phone to my tv/music system or connect to my laptop. However my laptop and tv communicate just fine through the same network.
Can anyone recommend anything for this?

Your saved wifi networks should connect automatically whether internet is available or not, you may receive a notification "there appears to be no internet connection".
Update to 10.2, if not available from your carrier then use Sachesi (see other threads).

Can the wireless card in my mac wear out and slow down internet connection??

can the wireless card in my mac wear out and slow down internet connection??

Yes the WiFi card can wear out but not what you would really call wearing out like a pair of pants do. It can start to fail causing the connection between your computer and your Wifi router to slow down, IE transmit and receive less data in a given time period. And then it will fail completely.
But as to your internet connection being affected by a failing WiFi card no that can't happen.
If you turn the WiFi off and connect the computer to your router with an Ethernet cable does your internet browsing and downloading speed increase? If it does then there may be something wrong with the WiFi card in your computer or the WiFi section of your router. Hard to say which.
If after connecting the computer to your router with an Ethernet cable and your speeds do not increase then it is a problem with the router or on your ISPs end.
