Connected to an active network but unable to load web pages

Hi,
I am using an old Powerbook with OS 10.2.x and am trying to add it to an existing network at home. The network is a DSL/ADSL connection, which is received by a modem and is passed on to a wired/wireless router. I have a PC which connects successfully to the router either by wire or wireless and is able to load web pages.
My Mac, however, does not. It indicates that it is connected to my wireless network, and shows full signal strength. It is assigned an appropriate IP address by the router. However, I cannot load any webpages. All I get is a 'server not found'. This is vexing me, and I have been at it for hours, but no solution.
Let me add that with the same settings, I was able to browse on my Mac also yesterday, but for some reason, I have no luck today. Can someone please indicate what is going on?

I am having the exact same problems. My laptop (Gateway) connects fine to the router, but my Mac does not. They sit right next to each other upstairs. The signal will SOMETIMES come through to my Airport card and when it does it is at full strength, but when i run Safari, nothing. I have tried to enter all the information that my PC has printed out and displayed for me, but i have no clue what half of the things are. and my applecare has expired so the people at Apple will not help which is extremely annoying. Sorry i can't help. But if i find anything i will let you know.

Connected to "open wireless network" but can't open web pages

Anyone ever to joined a "public" open network but failed to open web pages?
Twice I have entered a hotspot (Texas Highway Dept. Rest Area & an Air Force base recreation hall) and received the "Do you want to join the open network ...." prompt but once joined with full signal strength, I can't open any web pages.
Tried several variations of "Automatic" in Network prefs. I could join the network no problem and always got the green "connected to the internet via Airport" indicator. Same connection setup joins typical hotel and other hotspots no sweat.

Hi Tim-
If your Mac has been sleeping when you pull into the Texas Rest Area, and you hit the 'connect to open network'...
You might want to try a full restart of the mac, and try again.
If this has only happened twice to you (out of how many open networks that have been successful?)...then that's not a bad track record.
DNS is likely the issue, as mentioned here. A cure-all can often be a 'restart the mac', which might make some mac users gasp...gives you a chance to pretend you're a PC

Internet connected but unable to load web pages

Hi - My computer is an Imac, late 2006 model. For some reason I seem to be having problems connecting to the internet using the Airport connection. Using the Ethernet cable everything is fine no problems whatsoever, but wireless connection just doesn't happen. I have run through all the relevant diagnostics and checked the wireless router modem settings. My wife recently bought a MacBook - it connects wirelessly without a hitch. I even changed the iMac setting to exactly the same as the MacBook, but still nothing. I get the green lights in the Network Diagnostics screen, but when I try to load a page in Safari I just get an error message " Not connected to the Internet, or Server failed to respond".
My broadband ISP is Virgin Media (not a cable connection - it's ADSL) and the wireless router modem is a Netgear DG834GSP v3.
Any ideas anyone as am getting really frustrated at not being able to connect wirelessly.
Thanks in advance.

Hi I have been having exactly the same problem for the last couple of weeks, and can't explain what is happening either. The Mac seems to be connected to the Internet with all of the status 'lights' in Network diagnostics green. I am picking up an IP address but can't load any Web pages. Very puzzling !

Unable to load web pages. This is what I get when I enter them; Unable to connect

Yesterday I turned on my computer & was not able to use Firefox. Nothing had been changed on my computer. No web pages will load. When I hit enter this is the message I get:
Unable to connect Firefox can't establish a connection to the server at www.geocaching.com.
The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

It most likely means your internet connection is out. Wait a little while then try again. You might also want to reboot your computer. If that doesn't work, please reply.

Often unable to load web pages.

My MacBook har suddenly decided to not load web pages ...
I surf around, and maybe one fifth of all the web pages won't load in my browser (both Firefox and Safari). It isn't something about the web pages, because after some time I can get them to load perfectly. I contacted my ISP, and they couldn't find anything wrong. Besides, I can surf just fine from other computers (non-Macs).
I wondered if it was something about the port, since all other apps work perfectly (for example Google Notifier and Audium is always connected), but https doesn't any better. I've also pinged web sites for a long time, without any evidence of something being wrong. One strange thing is that traceroute sometimes gives me "no such host," and then a moment later, it works with the same address.
It's not Airport either, because I now use a network cable and have the same problems.

There are several possibilities that come to mind.
Since HTTP transfers often fail, but lightweight protocols such as AIM don't, my first thought is MTU (Maximum Transmission Unit).
The standard MTU for ethernet networks is 1500 bytes. This means that all transfers are broken into chunks of 1500 bytes each before being sent over the network. In some cases, certain network configurations (such as DSL links that use PPPoE) require a lower MTU such as 1492 or even 1460.
Normally this isn't a problem since the router tells the client what MTU to use but sometimes this doesn't work - especially if you're using a NAT device.
When there's a mismatch your Mac doesn't know that it needs to use a lower MTU so sends traffic upstream at 1500 bytes and the router chokes when it tries to cram that data into its 1492 link.
This is why lightweight protocols often work - the typical AIM packet is less than the MTU and therefore doesn't need to get truncated. However, large file downloads exceed the MTU and run into problems.
If this is the case you can force your MTU to be lower using the System Preferences -> Network -> <interface> -> Ethernet tab. Switch from Automatic to Manual and you'll see options for changing the MTU. Try lowering it to 1460 to see if it works. If it does you can try increasing it until you find the optimal value.
If it wasn't for your statement traceroute sometimes gives me "no such host" I'd be sure this was the problem. However, MTU doesn't usually cause DNS failures since most DNS requests are small.
If your DNS is failing and the ISP belives the DNS server is working correctly, that hints at a link-level problem. Packets are getting lost somewhere along the link between you and the server.
The first thing to check here would be speed and duplex. The fact that you've used both AirPort and wired connections hints that it's not a problem directly on your machine, but what about the rest of the links between you and the router? I'm guessing you have an ethernet cable between your base station and a switch, maybe another cable between that switch and the router? Either of these cables could have a mismatch.
Without knowing the switch it's impossible for me to tell how you check the switch port configuration - some switches have LEDs on each link that tell you the speed and duplex, others have a command line or web interface that will give you port status and statistics. If you have such a switch, check it. Also check the switch logs if you can - you'll often see error messages such as 'excessive CRC errors' which can indicate a duplex mismatch.
If you can't get the information from the switch, try manually configuring your devices. The same preferences tab where you set MTU can also be used to set speed and duplex. Just be aware that if you choose a combination that the switch doesn't support (e.g. you choose gigabit but you're connected to a 100mbps switch), then the link will go down.
Try different options to see if any of them work any better for you.

Connected to Wi-Fi network, but unable to access the Internet ipad 2

Hello,
i baught a new ipad 2 32 gb , 3g.... 4.3.5os
i am having an annoying issue regarding the internet connection..
where i am living i cannot connect a router so my laptop has a cable connected to it to access internet ... i had to create an ad-hoc ( to make my laptop work as a router)
( windows 7 btw)
now my iphone connect fine and i can browse internet, but when it comes to my ipad it only connects to the wi-fi but when i open the safari , a message pops up saying no internet connection eventhough as i said it's connected to WIFI with full signal !!
this is really frustrating and i've read many many blogs about this issue but none of them solved my problem and this was my last option is to send u guys askin for help...
p.s: i tried to click on renew lease but nothing is changed
ip adress : 169.254.90.xxx
subnet mask:255.255.0.0
router : blank
dns:blank

Try using an explict DNS server, such as
208.67.222.222 (OpenDNS server)
8.8.8.8 (Google DNS server)
System Preferences -> Network -> Advanced -> DNS -> [+]
The first entry you add (at the top of the list) will be the primary DNS server.

Unable to load web pages

I have had my blackberry for about 3 months and until recently I have been able to load and view web pages without any problems.   Now, after I enter a webpage address and hit return, I get a blank screen with 'Loading..' on the bottom, and it stays like that without progessing.
I get this whether I am at home with a wireless homehub connection or elsewhere.
I think the problem started when I was trying to access windows live messenger, so I don't know if that is the cause. I may have tried enabling java for the website, and again i don't know if this contributed to the problem. I have restored the original settings to try and resolve the problem but this hasn''t made any difference.
My phone also displays the lettes UMA near the signal indicator. I don't know what this means and whether it can explain the problem.
I am not particularly IT literate, so if anybody thinks they know what the problem could be. and can explain it in a straightforward way that would be very helpful.

Can get email, but can't load web pages

I have an Airport Extreme basestation which, up until a week ago, was working fine. Now, I can send and receive email, but I can't access any web pages. When I try, it just hangs and nothing loads. Nothing has changed in setup and I haven't changed any settings anywhere. My suspision is that my ISP (Charter) changed something that my Airport is unhappy about.
I called Apple, and they told me it's Charter fault. I called Charter, and they told me it's Apple's fault.
I also called my local Apple store (not an official Apple store, but a small local reseller) and they said they've had an unusual number of people in the area reporting the same problem. Unfortunately, they don't know what could have happened.
Any idea what the problem might be or what I can check? Any help would be greatly appreciated.

It sounds like it might be a DNS issue.
In a browser try http://17.254.0.91

(X230) Connected to Wifi with excellent signal but unable to load internet pages:

Hey everyone,
Hoping for the community to help me figure out a problem of mine.
Trying to connect my X230 to internet through a new router (Asus - security type WPA-Personal) and although the laptop connects without a problem (98% signal strength), internet pages are not loading. The diagnosis tool isn't finding anything and I could add that other laptops do not have the same problem when connecting to this router.
My tech level is rather low so I don't know what more I could add to help you guys get a clear view of the situation/problem so if more info is needed, let me know. I won't be far.
Thanks a lot,
Patrick

Thanks for your help jdhurst,
To answer your questions:
1. The machine connects fine on other routers. For example Starbucks (Unsecured), friends house (Linksys on WPA2-Personal), two different schools (WPA-Enterprise and WPA2-Enterprise).
Maybe it's a coincidence but its the first time the machine tries to connect to a WPA-Personal...
2. Several other computers connect well to this router. Which leads me to believe that the problem is with the X230.
3. How do I do this if I can't access internet with the said machine? (sorry, a bit of a noob).
Extra notes:
A) When I open up the Wireless Network Connction Status, it says ''No Internet Access'' next to IPv6 Connectivity.
B) Although this router is set on WPA-Personnal, the Lenovo Access Connections manager seems to think that specific router is in fact a WPA2-PSK
Hopefully this will generate more thoughts on the subject.

Wireless signal but unable to view web pages

I have a WRT54G version 6 wireless router, it's security enabled and my XP laptop recognizes the signal and says I'm connected, excellent strength. Problem is that when I open IE no pages will load, if I connect the modem to my ethernet connection I can connect fine.
Any ideas?

I'm having the exact same problem. This morning I went to the website to follow the directions from Easy Answers: How to set up PPPoE DSL connections with Linksys Router......just a great help this was...after all the plug/unplug/plug/computer off/on/off/on....When I clicked on IE icon to connect to the internet, All it Connected to was this LINKSYS page...couldn't go any place else!!!
I've had to unplug everything and go back to the DSL modem direct to this PC to get on the internet to go to this link....Now, interesting it does make sence that both the modem and router can not have the same IP address, but if I change the router..what do I change it too??? May DSL works at 192.168.1.1 which is the same as the link I went too to get the Linksys page. Thanks

Unable to load web pages and iTunes store

Since upgrading to Yosemite 10.10.2, I am unable to surf the web or even access my iTunes Store. Is anyone else facing this issue?

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

My Apple Tv is connecting to the Wifi network but is not connect to the internet. So when I look for it on my Airplay it doesn't come up. I have 3 other ones already working on the network and they are all fine.

My apple TV is finding and connecting to the Wifi network but then says it is not connected to the internet and then I cannot find it on the iPad through airplay. I don't want it connected to the internet (as in www.) because for the use I have I only need to use the Apple tvs locally in a sports hall as scoreboards. I have 3 others working on the same router and they are working fine (as of yesterday)
On my screen I see (obviously not written like this)
network connect- yes
signal strength- fine
Ip address- fine
DCN- fine
Activation- Failed
This is the only negative I can find and the statement that the Apple TV has connected to the wifi but is not connected to the internet.
Where has it gone wrong for me. Please help

It is not properly connected to the network.
Make sure location is set correctly
DNS should be on auto (settings - general - network)
Try ethernet
Signal strength on device won't account for issues, you would need a network report from istumbler, netstumbler or similar. This will show accurate signal strength along with noise and nearby networks

I am able to connect to my wifi network but am not able to connect to other computers on my network. I have installed windows 7 on parallels desktop, from windows i am able to access my network computers. But from Mac i can only access internet but not network computers Please help

Ok, well if you're sure that there are shared folders on your PC's, then try this:
Click somewhere on desktop, so you're in finder > Go > Connect to Server (shortcut to all of this is Command + K) then type in: smb://ipaddresshere
eg:
smb://192.168.1.7
Then either connect as guest, or login with the PC's (not your mac's) username & password.
