Just Installed Tiger Can't Connect to Internet

I just upgraded to Tiger this morning. Ever since when I attemp to connect to my wireless router through airport, my router crashes and resets and all the computers that are connected to it lose the connection. I believe that my airport is somehow acting erratic and somehow crashing my router through the wireless connections. Please help!

Hi Brian,
You need to reset the AirPort Preferences (caches), follow the tips here and post back:

Just installed tiger, can't shutdown

Hi I just installed Tiger on my Emac. It works great. Just that when I initiate shut down,screen stays on. everything quits o.k. after finder quits all I have is the desktop picture, and the computer stays on.
I am able to shutdown by pressing power button and since all apps closed o.k. there is no data loss. I do not have Classic running when this happens. I have restarted from Tiger disk and run "verify" and "repair" disk permissions.
Any other ideas what is going on?
thanks

Also, I would try using Disk Utility to repair your startup disk (hard drive) as shown in Dr.Smokes Resolving Disk, Permission, and Cache Corruption.
Repairing the hard drive is different then Repairing Permissions.
Here's a no shutdown tip sheet that covers what macjack helpfully provided in more detail;
This is for a Mac that won't shut down. Launch Activity Monitor (or Process Viewer if you're running a pre-Panther OSX) and see if there are any active applications besides Activity Monitor ( items with icons next to the name), select them, and click Quit Process.
If an app won't quit by clicking Quit, click Force Quit. Then try shutting down again.
If that does'nt work start killing off system-managed programs ( items without icons ) . Be sure to quit only the programs your user account is running; don't quit anything identified as "root" or "nobody" in the User column- and whatever you do, don't quit any of the following : loginwindow, Window Server, ATSServer, or SystemUIServer, which make up the foundation of Mac OS.
Quit one process at a time, and then shut down after each kill until you find success!
I wish you luck!
p.s.If you install two of a single user licensed third-party application on different computers which are networked, this symptom may occur. If that is the case, a solution is to perform "Erase and Install" for both computers.

Do you have a firewall turned on? If so try turning it off.
Have you configured the router properly?

Just got new ipad2 and can't connect to internet...recognizes wifi network but won't connect

just got a new ipad2...recognizes wifi network at home, but can't connect to internet...help???

I just had a similar problem. Both the ipad 1 and ipad 2 in my household quit connecting to the network even though it seemed to recognize it. if you think it is recognizing your network, just not connecting, check to see if bluetooth is turned on. i had to turn bluetooth off and then manually enter the DNS number.
My solution also came after I re-started my network and reset all the settings on the ipad2. The DNS number then showed along with IP submet Mask and router. I used that dns number to enter into ipad1 after turning bluetooth off on it.
Totally unscientific fix that may have been more coincidental than correct but you might try it. BTW--no idea how bluetooth even got turned on to begin with.

depending on your experience level should tell you all you need to know.
You don't need mobile me, you just need to know your mac's ip and have vnc
client software of some sort running on the machine you are travelling with.
Read the entire article, as once you get past the part about monitoring multiple machines there is some useful info.

Can't connect to internet on my old g4 flat screen, network + airport ok

I installed an airport card on the g4 (dome) and connected to our wireless network, which gets a signal, (though the status is "not available"). I can't connect to internet (server not recognized), and every time I check the internet assistant app, the setting has been changed back to modem. The router is in the basement: my iMac is on the first floor and works fine, the g4 is on the second floor. Is that too far away? Do I need to update the g4? Two minis also work fine, one on first floor and one in basement. Any help appreciated.

Which iMac G4 do you have? Some iMac G4s are 802.11b while the later ones were 802.11b/g.
If your wireless network is configured for "802.11g only", the older 802.11b iMac G4 won't be able to connect.
If your wireless network is configured for "802.11n only", the iMac G4 won't be able to connect since it isn't compatible with that.

Can't connect to Internet via Airport

I have a PPPOE ISP account. Before upgrade to Lepoard, just fine. Now I can only connect to internet using cable via my router moderm. I cannot connect my wireless router.
The wireless router will appear to be connected but it said self assigned IP. If I hardcode an IP eg. 192.168.11.2 to it. The Airport status will become connected but still cannot dial into my PPPOE account. An message no PPPOE service will appear. But if I plug in the LAN cable, everything work fine. Why this happen? My wireless router work fine with my Window XP and my Mac (before upgrade to Lepoard) What configuration should I change? I am an idot to networking. I have download all patch and has tried boot to safe mode etc.
Anyone can help?

By power downs do you mean Sleep?
One thing that might work is to set the IP to Static in Network>Configure IPv4>DHCP with Manual Address.

5 out of 6 devices can't connect to Internet

Just to preface, this was all working hours ago.
airport express, Mac book pro, ipad, boxee box and Western digital live Nas all can't connect to internet.
my Samsung Galaxy s3 has no problems however.
normally if I can't get an ip address I would just say the Internet is down from the isp. But because I've got one device where it's working fine gives me cause to think otherwise.
Any ideas would be greatly appreciated.

You want the device that is directly connected to the modem to furnish the PPPoE service.
This is sounding like you had your Mac connected directly to your modem at one time, so in that type of setup, the PPPoE connection on the Mac would have been correct.
But, since you have added the Time Capsule....and it is now the device that is directly connected to the modem.... the Time Capsule must be configured to provide the PPPoE connection service, not your Mac.
Open AirPort Utility - Click Manual Setup
Click the Internet icon
Your settings should look like this:
Connect Using = PPPoE
Account Name = Your user name with your ISP
Password = Your password with the ISP
Verify Password
Service Name.....leave this area completely blank
Connection = Always On
Disconnect if Idle = Never
Update to save settings and the TC will restart
Either delete the PPPoE connection on your Mac, or if you want to retain it in case you need to connect your Mac directly to the modem at some point in the future, make that connection inactive.
If you are connecting an Ethernet cable from one of the LAN <-> ports on the TC to your Mac, you want the Ethernet connection to be active on your Mac. This should happen automatically if the PPPoE connection is inactive or has been deleted.
Be sure to power cycle the entire network at this point. Power all devices down, or der is not important.
Wait a moment or two, then start the modem and let it urn for a moment by itself
Start the TC and wait for a green light
Then start each device one at a time until the network is back up

Can't connect to Internet after sleep mode

Hi,
Most times after put my iBook in sleep mode and reopen it, I can't connect to Internet. I use a normal cable connection by ethernet, but at these times, when I check the network status, it says I don't have any cable connected. The modem apears to be OK, with the computer's light on. I plug off and plug in the cable and it doesn't change and it happens the same when I click in DHCP renew - it just doesn't give any IP adreess. I need to restart the computer to get the connection again.
Ibook G3 700 Mac OS X (10.4.7)

I am trying other solutions today.
It can not change to another wifi network without switch off the wifi.
That's mean I have switch off and re-open the wifi signal every time when it show like this capture.
I waiting for more than 5 mins and it will search another wifi network automatically but it still "No internet connect".
My MacBook Pro is no any WiFi issues.

Airport card working but can't connect to internet

hi all,
airport card (just plain airport card) is working and is connected to a verizon fios router. signal very strong. just can't connect to internet via safari, camino or firefox. running 10.3.9 os. i've rebooted twice to no avail.
altho, i can connect on my g4 powerbook using the same router.
why isn't the g4 flat panel imac connecting? any ideas?

In the Network system preference panel, is the wireless component
selected and in the list of items in the configuration the Mac sees?
You can drag the item(s) into preferred order of use, if there is more
than one, ie: dialup modem, ethernet connection, airport base.
If both computers have a similar operating system, it may be an
idea to look carefully into each, and not change anything in the
one which appears to work correctly; to look for differences.
Does the wireless router provide support for 802.11/b as well
as wi-fi 802.11/g? The older airport card runs on the older spec.
