Please help... Reset PMU and can't connect to wireless internet

I have an iBook G3 800. I took a trip and when I unpacked it, couldn't get it to turn on. I looked online on another computer and read the suggestion to reset the PMU. I did it, and my comp turned on. Only when I tried to connect to a wireless network, it didn't work. It seemed to be connected, but no webpages would load. I tried in a different location, with a different network, one I had used before. My comp identified the network, but when I tried to connect, I get an error message: "There was an error when trying to connect to the airport wireless network etc etc."
BTW, I had further trouble with starting up, but resetting the PMU worked, and that problem seems to be behind me. I also tried resetting the PRAM (or whatever equivalent the ibook has. I'm pretty ignorant.)
Thanks in advance for all your help.

Welcome to Apple Discussions!
I travel a lot, and I find the easiest thing to do is to use the Setup Assistant to set up a new location. That will usually get you connected, and then that location will be saved under whatever name you gave it. Then if you return to that location, you can just click on it to get that particular setup. I have done that with both dial up and wireless.
Good luck!

Try changing the channel in use in case you're getting interference.
If you have WEP enabled on the Internet Sharing it'ss worth disabling it whilst troubleshooting the connectivity issues.

Please Help with Forms and SQL Plus Connection Issues in XE

I am not able to connect with the Forms Builder or SQL Plus with the following errors:

Thanks, Vikas!
But I did a search for 6iServer.conf and did NOT locate any such file
Please help
TIA

Shankar,
It would have helped if you had indicated what is the full version of 9iAS that you have installed. By default the portnumber that is used is 7778.
As per the entries, they should have already been made in the config files. But check that the 6iServer.Conf file and it should contain the entries that you are being told to update. If not, then add the entries in the 6iServer.conf file and that is all you need.
HTH.

HT4623 Please help. My iphone can not connect to SIM card , I tried many times there is no hope.

Just bought a macbook and can't connect to the internet. very frustrating

i can't connect through my wireless router. it reads it but can't connect. my brothers hp laptop connects to it and works. i brought it to work and tried to connect to the router at work but it failed again. but my bro's hp just reads it right away. i need some help please.

Hi,
The same happened to me, but here's a fix.
If it is password encrypted, when you first turn on your macbook, and they give you the internet connection list, Click on advance, and select "This computer does not connect to the internet" Then everything will finish installing.
Now when you see the wireless symbol on top of your screen (right next to the blue tooth) select Airport ON if it isn't enabled. Then connect to your wireless router, and when it asks for the password, click on the internet password type, and select the "Wireless WEP 12/48 key...or something like that" and it should connect. That is what I did to my macbook and it worked

Airport has a self assigned IP and can't connect to the internet

Thats what i get when i want to share an internet connection from my mini, macbook and macbook pro.
none of them give an internet signal out to the world, they used to, but i think the last software update changed things.
so, being that i have the same problem with 3 machines i can say for sure its not a hardware problem, tried manually assigning an ip address, changing the network channel to any of the options.
still im giving no internet to any device. Running snow leopard 10.6.5 on c2d intel machines.
please, help me, as im getting heavy complaints from other people who havent got internet access for days thanks to this.
thanks
ps: i have no router. i just have one mac connected via ethernet to the internet, and i want that machine to share internet via airport / wifi to other devices such as a macbook or an ipod touch
this worked wonders for a while, then stopped working, then worked again, then stopped. it seems it comes and goes as macOSX updates come and go.

Is your computer which is acting as your gateway for the rest of your network running its firewall and blocking the traffic from the other computers? Can your other computers connect to each other? Ping each other?

I suddenly don't have an IP address and can't connect to the Internet!

A friend came over about a week ago and started playing with my MacBook pro. For most of the week I kept dropping the wifi signal. Then yesterday it wouldn't connect anymore. I tried restarting it several times, and renewing the DHCP lease, and removing all the remembered networks. Tried running the assistant and diagnostics, with no help. It says I don't have an IP address and that's why I can't connect. Any help?

I have windows on my mac and lost audio and can't connect to the internet.anyone else having this problem? Or have it installed at the apple store?

I have windows on my mac which was installed at the apple store. I have lost audio and cannot connect to the internet on the windows side. Mac is ok. apple genius and tech support can't help me and say I need to go to microsoft. In fact the tech support was unaware that windows was loaded on by the apple retail store. Has anyone else had this problem?I recently bought fusion thinking this would help bridge between the two( as told by the genius bar) but it didn't help.Any ideas?

hey mate i used to have the same problem and i got computers maintenance guys out to fix it in the end and all it was, was the router.. got a new one and it was all good after that! i think some routers just arent compatible for some reason or another.

MacBook Pro can't connect to wireless internet

I have a MacBook Pro that I have had from about 3 years now. It's been great but earlier this week, it wasn't able to connect to the internet here at my school (college). I didn't think too much of it because my schools internet is always spotty and goes down from time to time. Yet when I go on to my computer tonight nothing I do with my airport or computer will get my webpages to say anything other than "Server not found". I tried turning off my airport then back on and reselecting my network because usually that helps. It would say it connected and I would have full bars but still the same error message. I tried again, and when I did it this time, I did it from within the system/network preferences. When I did this, I watched the connection of my airport go red, then I would connect and it would go to yellow saying I had no IP address. I would then sit and wait and eventually it would fully connect giving me the green go-a-head. But, again when I would open up my internet, I would get the "Sever not found" message. I would then quit my firefox all together and tried again that way and still same massage. I restarted my computer and tried again...nothing. I became more concerned because my roommate could get on the internet just fine and I could use the wireless in my room through my phone. I was consered that now this was a matter with my computer and not just the internet, so to make sure I got out my ethernet cable and hooked it up with my connection in my room. This would work!
So my question is...
My roommate brought up the possiblity that this problem is with some sort of chip in my computer that helps me connect wirelessly to the internet and that it has gone bad and needs to be replaced. It this so? or is there something else I need to be doing? (and I have been trying lots of thing) This is vital to me getting my work done because we are in the middle of the semester and I need my wireless!!
Please help!
Thanks!

thats... odd
thats a real world IP address. So that means you dont have an actual router doing NAT.
It's also very unsecure. I HIGHLY advise tweaking your home network very soon. Without alot more info theres not much that I can really advise though.
You said your roommate can get on the wireless fine - what IP address does he/she get?
Also, i think you said if you plug in with a physical wire it works as well - what IP address there?
Do you know if you have an actual router? Or is this simply a cable or dsl modem?

Can't connect to wireless internet with Virgin

Installed Virgin media three weeks' ago and have not been able to use the wireless internet since. We have had 2 modems and 2 routers and spent about 12 hours talking to various people at Virgin but still does not work. Had AOL before with no probs. We have been able to connect it a couple of times but as soon as we turn off the mac, it loses the connection. Works fine on the modem with the ethernet cable. A lot of the time we can't even see the router on the airport but when we can and we try to connect, it just comes up with 'timed out'. The routers we have are D-Link and Netgear. Has anyone else had a similar problem? I'm just wondering if it is a problem with the Mac but we can connect to neighbours' unsecured networks. Please help!

thanks for your help, but sadly this did not work. even when i click the wireless airport icon on the top taskbar, no networks show up on the pull down menu. the only option i have is 'other.' shouldn't my secured network at least show up in the pull down menu, to which i provide the password?
is there any way to get this extreme card to work? has anyone else had this same problem with their iMac G5? this is ridiculous, thanks.

CAN NOT CONNECT TO WIRELESS INTERNET ON IPAD 2, CAN NOT CONNECT TO WIRELESS INTERNET ON IPAD 2

i had to switch out my ipad and now for some reason when i try to conncet to the internet it not letting me please help some one i have reset wifi like 5 times it not that because the computer works fine with the wifi

Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398
Additional things to try.
Turn Off your iPad. Then turn Off the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
On your iPad go to Settings > General > Reset > Reset network settings and see if that enables you to connect.
If none of the above suggestions work, look at this link.

Can't connect to wireless internet with my airport extreme card.

hello, i need some help connecting to our wireless router. i do not have an airport base station, i am trying to connect to a third-party, secure wireless network. anyway, i've called apple, i've called linksys (the router company), and i am still using hardwire connected to the router. whenever i click the airport icon on the top taskbar, no networks show up. i have had my pc laptop in the same room as my iMac G5, and the laptop can autmatically connect to the network, but my iMac cannot. i am running out of options. i connect with a secure, wireless internet. its wep, whatever that means, and i've tried my user name and passcode numerous times, but to no avail. what do i do????

thanks for your help, but sadly this did not work. even when i click the wireless airport icon on the top taskbar, no networks show up on the pull down menu. the only option i have is 'other.' shouldn't my secured network at least show up in the pull down menu, to which i provide the password?
is there any way to get this extreme card to work? has anyone else had this same problem with their iMac G5? this is ridiculous, thanks.

Help with my daughter's iBook connecting to wireless internet

My daughter wants to connect to a wireless internet "node"(not sure of terminology) at her local cafe. She has an old G3 double USB iBook. What can she buy as a USB device to connect. Any help appreciated. Cheers

She needs an USB or Ethernet adaptor which supports any 802.11 protocol, or the original AirPort card.
