Why can my macbook only access the internet from certain wireless sources?
I have tried connecting to the internet at my friends houses with my macbook but even though I can join the network, the internet itself doesn't work. Is there a reason for this? I've even tried to connect to the internet through a wireless network that my friend was accessing with no problem, from his macbook.
Possible reasons for being unable to connect to a strange network:
- Wrong proxy information
- Wrong network password
- Your friends router has "MAC address filtering" turned on.
You might find you can connect by creating a new location like this:
System Preferences > Network
Select the AirPort from the left hand side
Click on the Locations combo box and select Edit Locations...
Click on + to add a new location, give it a memorable name
Select the AirPort tab and enter your network name
Select TCP/IP tab.
Configure IPv4 Using DHCP
Now click on Renew DHCP Lease. After a few seconds you should get an IP address (probably 192.168.x.x)
Click on Proxies tab.
Select Auto Proxy Discovery and Use Passive FTP
Click on OK and Apply, etc.

HT1695 Why can't I connect to the Internet when I not at home
Why can't I connect to the Internet when I'm not home
If you do not have an iPad with 3G cellular service, you can only connect to the internet when you have access to Wifi. Wifi is not available everywhere, but there are places that do offer free Wifi service, such as Starbucks, Panera Bread, the Airport, etc. When you are at a location which offers free Wifi access, you have to join their network, which is usuall nothing more than touching a connect option that should automatically pop up, when you open Safari on your ipad.

Why can't I connect to the Internet on my Adobe Reader? And why do websites tell me I don't have Adobe downloaded when I have an updated version on my computer? It is an IPad,does that affect it?
Also, download and open the free Adobe Reader app. Then read the Help section to figure out how to use it.

Accesseing the internet from my Nokia 6600 on my P...
I have still not been able to access the Internet from my Nokia 6600 to my PC. I have tried using bluettoth to no avail. Can someone help me. If you have accessed your internet from your Nokia 6600 to your PC please tell me how to do this
I will truly appriciate it.
Moderator note: e-mail address remived, it is unwise to publish personal contact info on the web.
Message Edited by michaels on 01-Oct-2008 03:19 PMI ain't got a Nokia 6600 but all models of Nokia with modem works the same way. I don't advice using bluetooth for connection is rather erratic; use cable. Make sure all configurations of phone from providers are configured like data access points. I presumed you have loaded succesfully pcsuites, in the same way the modem drivers. You can check it in your pc/laptop devices config.
Configure your browser to connect by dial-up connection(tel no. & sometimes user/password from provider), select the Nokia modem(sometimes better to disable temporarily the built-in modem of PC/Laptop if it exist), you'll be connecting by gprs & there is tariff per minute connections more expensive than landline by modem of PC/laptop.

I can't access the internet using my home wi-fi. My wi-fi is working on my home computer, and the itouch can access the internet at another person's home using their wi-fi. I've looked in the settings, and can't seem to see any differences.....i'm a techno dummy - so please respond in very basic info
Before resetting try restarting. Or you can go to Settings from the home screen > Wi-Fi > your network and scroll down to 'Renew Lease' and press that. When you do you should see a button labeled 'Renew Lease?' and another labeled 'Cancel'. Select 'Renew Lease'.
You can either back out of that screen back to the home screen or just use the return button to go back to the home screen. Then select Safari and see if you can hook in.
I have to go through that process every five or ten minutes or so when in the second story of our house - weak router signal up there. -
Can't able to access the internet in window server 2003 sp2 64bit.
Hi,
recently i installed , windows server 2003sp2 64bit, every thing was perfect expect, internet.
Ican't access the internet in that server, i tried to update the LAN drives but no use, I tired t install Adapter drives no use.
What i have to do now,
Thanks in advance,
Surnedra Mannem.Hi
Is this server in a domain or stand alone?
Are you plugging the server direct in to the Internet Router or via Switches?
What is the status of the Network Adapter Connected, Disconnected or Limited?
Could you please tell us what is the IP address you are getting on the server?
Try turning off the firewall also what browser are you using to access the internet on the server.
Thanks -
Why can't I connect to the internet?
I am getting an error message cannot connect due format being too small. Am having other problems with the Icons being too large The font is so large cannot read the whole pag.
Hi mamieham23,
I am sorry to hear that you are having problems accessing the Internet on your Firefox OS mobile device.
What is your device model and version? What country was it purchased in?
Are you able to use the Internet at all, through the Wi-Fi or the cell phone data? Do you see a 2G, E, 3G, H, or H+ icon on top of your notification bar?
Regarding your problem with the webpage, you are able to zoom out of most webpages by doing a pinching motion with two fingers on the screen. If the website does not support this feature, you may need to contact the website developers directly for support.
If you are able to share the link for the website that you are having problems with, we may be able to provide a workaround.
We look forward to hearing back from you.
Thanks!!

I just reinstalled the computer (windows xp home edition) due to spyware but now I cannot access the internet..
I am sure that the router is working and that the adapter works as well as when ever I check, it says that I am "connected to the access point".
But I still have NO access to the internet.
What do I do?Since you re-installed your Operating System, usually you need to reinstall the adapter.
But in your case, the driver is still there.
Linksys adapter has its own utility. same as with windows. Linksys has Linksys Monitor and Windows got Wireless Zero Configuration. Now, when both of them are running, that's the time you cannot access the internet because they are conflicting.
try this.
Click on START --> Run
type " services.msc" and click ok
scroll the page on the most bottom part and look for Wireless Zero Config
Right click and click on " start or restart"
Then click on start-->control panel
Click on network Connections
Look for Wireless network Connections & right Click on it.
Select "view available wireless networks"
note: it would usually say if you have configured another program.. use that software.
Look on the left side of the window
Select " change the order of preferred networks"..
check the box that says " use windows to confgure my wireless network settings"
try to view the wireless networks now
You should see your network and just cOnnect to it. -
Why doesn't my NB505 access the internet when I bring it to a WiFi location?
I have a NB505.
I have brought it to a Dunkin Donuts and to several Starbucks so as to get WiFi
The notebook just does not work as far as accessing the internet at a WiFi location.
Do I have to set it up somehow?
Does a NB505 have no capacity to access the internet through WiFI?
Help pleaseSince posting that question I have found out how to use the notebook in a WiFi place.
Thanks.
However also since that posting, my laptop has seemingly konked out.

How to make Firefox access the internet from Oracle Ent. Unbreakable Linux?
Hello
I have a Dell Duo Core x86 laptop that multiboots Windows 2003 Server, Windows XP and Oracle Enterprise Unbreakable Linux. I use Internet Explorer to
access my email while at the library so I know my laptop can access the internet. I just installed the Oracle Enterprise Unbreakable Linux in text mode and
I can still access the Internet but only if I use one of the Windows operating systems which is why I am keeping them for now. The reason is because when I
use Oracle Enterprise Unbreakable Linux, when I select Firefox to access the internet I get these messages:
"Server not found
Firefox can't find server at www.hotmail.com
-check address for typing errors
-if unable to load pages check network connection
-if computer or network protected by firewall make sure Firefox permitted to access
web"
None of those reasons are true for not gaining access to the internet. I want to use Oracle Enterprise Unbreakable Linux from now which is why I installed
but I need to know:
1) Why do I get the "Server not found" and the other error messages when I try to access the internet using Firefox and what do I have to do to make Firefox
access the internet successfully?Hi,
First you must confirm your laptop with Oracle Enterprise Unbreakable Linux can access internet.
Please open a terminal, input the following command
1.ifconfig
2.cat /etc/resolv.conf
Regards

Network Two Macs, access the internet from both.
Frustration.
I have a Mac Pro, and an older Power Mac G4. I had them networked in such a way as both could access the internet. The G4's access stopped working because I had a power outage, and had to restart everything. I am guessing this has something to do the cable modems MAC address.
At any rate: Here is what I have. A LinkSYS Cable Modem, A Netgear Switch (8 Ports) and the 2 computers. Both computers are connected to the switch. The cable modem is in port 1, the MacPro port 2, The G4 Port 3. The MacPro, does connect to the Internet. The G4 does not. I had this working before. It worked wonderfully. But I think after restarting everything, and somehow not getting the sequence right or something, I cannot get it back to working. I don't want a router. As it slows down my 16MB per sec net connection, and ruins the ping rate for gaming.
Any input, light you can shed on this situation is of course greatly appreciated. Merry Christmas!Austinscott wrote:

Nope. The MAC address does not change. The IP address might change.
At any rate: Here is what I have. A LinkSYS Cable Modem,
what model cable modem?
A Netgear Switch (8 Ports) and the 2 computers. Both computers are connected to the switch. The cable modem is in port 1, the MacPro port 2, The G4 Port 3. The MacPro, does connect to the Internet. The G4 does not. I had this working before. It worked wonderfully. But I think after restarting everything, and somehow not getting the sequence right or something, I cannot get it back to working. I don't want a router.
I suspect that you have a router, built into the cable modem. Virtually all Linksys cable modems have a router built into them. In addition, unless you have arranged to have two Internet connections from your cableco, you must have a router to have two devices connected to the Internet. If you have a router you can have multiple devices on one connection. If you don't, you can have only one. You may have turned off the router functions on your modem. What is the IP address showing on your Mac Pro? If it is something in the 192.168.x.y range, where 'x' is a number from 0 to 255 and 'y' is a number from 1 to 254, or in the 172.z.x.y range where 'z' is a number from 16 to 31, or in the 10.x.x.y range, then you probably have a private network which means that you have a router built into that modem and its router functions are turned on. If your IP is a different number you probably either don't have a router built in (unlikely) or its router functions are off (very likely).
If your have a private network and your G4 is not connecting, you need to determine what the IP is on the G4. If it is 0.0.0.0, then you have a damaged network card and need to replace it. If it is 169.254.x.y then your G4 is not seeing the router for some reason, likely because the router functions on your modem are off. If it is something else we need to know what it is.
As it slows down my 16MB per sec net connection, and ruins the ping rate for gaming.
