Despite troubleshooting, still can't connect to the internet on my Dell Laptop

When trying to connect to the internet, I get the following message: Server not found Firefox can't find the server at www.apple.com.
I cleared recent history, but still can't connect.

Some laptops have a switch somewhere on the machine, usually underneath which you can use to prevent the laptop from connecting to the Internet.
Can you connect with Internet Explorer? If you can, then it may be that your firewall is blocking the connection. See [[Firewalls]]

Safari 5.1.1 can't connect to the internet. Every other browser can.

I've tried resetting Safari, reinstalling Safari, and resetting my router to factory settings. Safari still can't connect to the internet, but everything else on my Mac (Snow Leopard 10.6.8) can.
I recently tried setting up Open DNS just because I've had problems with Comcast lately. But I've since returned DNS to be detected automatically.
Thoughts?

Why is my wi-fi signal is going strong, but I can't connect to the internet?

Before I begin, here's my set-up:
My wi-fi signal (on the top right side of my MacBook) is going strong (with all the bars). And a green light is lit up on my Airport Extreme. For some reason, I still can't connect to the internet/use Apple Mail/use iChat. I don't think that there's anything wrong with my MacBook, as my wife isn't able to connect to the internet with her iPad or with her laptop either.
I'm thinking that I have the strong wi-fi signal showing up on my computer because it actually is connecting to the Airport Extreme, yet the airport extreme somehow isn't connected to or isn't able to connect to the router. Would this be correct? Any ideas of how I might fix this? I tried unplugging and replugging everything for a few seconds. However, whenever I use a hardwire ethernet connection to my MacBook, my internet and everything works.
ALSO, of note, I just purchased an Apple Time Capsule. I just realized that it functions as a wi-fi base. Any chance that my computer, my wife's iPad and laptop are just connecting to the Time Capsule instead of the Airport Extreme?
Any answers would be more than appreciated. Thanks!

Deselect Proxies if selected.
Safari > Preferences > Advanced > Proxies:
Click "Change Settings" button
The network preferences window for Proxies will will show up with "Proxies"
tab selected.
Under "Select Protocol", uncheck any box if selected.
Click "OK", then "Apply"

Can't connect to the internet with my wired desktop computer or my wireless laptop!

I'm stumped? Tonight I was surfing the internet when all of a sudden I lost my internet connection from my desktop computer? I tried various solutions to fix this but nothing worked? I'm currently hooked up to a wireless router model WRT160N. Here's the clincher, I unhooked the ethernet cable from the port on the router labeled "internet" and hooked it back into my ethernet port on my desktop computer and persto everything worked fine!! I can't connect to the internet either using my laptop!? I hooked everything back up to my router and tried accessing the internet but nothing worked? When hooked up like this I lose my internet connection on my desktop computer as well??? I'm confused??? What could be causing this??? I've just recently configured my router last Satuday with the help of a Linksys technician?? I bought my router last tuesday!?! Need help here!!!! Both my laptop and desktop computer have Windows Vista Home Premium as OS.

You need to re-configure your router...

My WiFi signal is good but I can't connect to the Internet and it's still loading the server

My WiFi signal is good but I can't connect to the Internet and it's still loading the server. How can I fix this or make the server connect faster?

iOS: Troubleshooting Wi-Fi networks and connections

Was always working and today I get a message that it can not connect to the internet. Internet Exployer works fine. So, I tried uninstalling the program and reinstalled. Still did not work. check out the proxy and firewall no problems there.

I get a message can not connect to the internet when trying to open Mozzila Firefox. It was working fine until my internet service went down. Once back up it was not working. I have tried installing and uninstalling the browser. I have looked at the firewall and proxy on my computer. Still not working Internet Exployer works fine. Deleted all cookies also.

Did you check your security software (firewall)?
A possible cause is security software (firewall) that blocks or restricts Firefox without informing you about that, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.

Installed 8.1.1 and still can't connect to the iTunes store

So for about 3 weeks I've been unable to connect to the iTunes store. I've allowed iTunes as an exception to my firewall; I've even tried turning the firewall off. I just installed 8.1.1 and I still can't connect to the store--what is going on? Any advice or anything?

Ah! I got it! I tried turning off the Symantec and that wasn't it (but thanks for the suggestion), but after poking around on the forum, someone said to try this:
try going to control panel > internet options > Connections > LAN settings
Then uncheck "automatically use a proxy server"
And voila, iTunes works! Thank you so much for all your help though; it's nice to know that someone is trying to help.

After update I can't connect to the internet in no way, shape or form

I rarely update because: 1) something always breaks when you update (like now) and 2) I don't like to deal with new crap like GNOME 3. Anyway:
I bought a new router (TL-WR1043N) and configured it with an old Ubuntu because connecting to 192.168.1.1 didn't work on any of my Arch Linux installations. Now... here's where it all starts... I can't use the 'n' wireless on my laptop since I have to install something to use WPA, and to install that I need to update, but I don't want to deal with GNOME 3 and Firefox >3. But I gave up eventually gave up and connected my laptop to the router by Ethernet cable. Setting that up was very easy: 'ifconfig eth0 up; dhcpcd'. Voila! I updated my whole system and restarted. To see how badly I damaged my system I opened Nautilus (I use Openbox with some GNOME programs): shock and dismay, the fonts are visible from the moon. I guess I'll have to quit using GNOME programs completely now but I expected that. I used to use KDE back in the day and when KDE4 came forth from that unholy pit, I immediately abandoned it for GNOME. This time we had more time to prepare, everybody knew what GNOME 3 was going to be. I started using Openbox quite a long time ago.
Anyway: Now to fix my wireless right? WRONG! I can't connect to the internet on cable to get the packages for wireless. I installed Windows 7 64 on the same laptop and it connects to the cable. Ubuntu 9.10 Live also connects, but due to the changes of rc.conf and network stuff I can't connect at all with Arch Linux.
So I decided to abandon it completely and reinstall from scratch. But the Live CD also doesn't work. With all the ways I've tried it all comes down to this:
dhcpcd always times out waiting for a carrier and 'ip addr' shows 'eth0: <NO-CARRIER, ....' if the interface is up. I'm not sure what information I should give you, but I can't paste any here since I can't connect to the damn internet on that laptop.
About the router: the cable is plugged on port 1 and the LED for it flashes if I reboot the computer. In Windows it stops flashing while it connects and flashes again when connected. I removed 'network' from DAEMONS and it flashes till I start it with '/etc/rc.d/network start'. This hangs for a while and returns '[DONE]' even though it doesn't work and the LED never flashes again on the router.
In rc.conf I have exactly what the example says for DHCP. In any case, it doesn't work with the Live CD either.
EDIT 1: From lscpi: painstakingly typed:
06:00.0 Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)
07:00.0 Ethernet controller: Realtek Semiconducctor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 01)
EDIT 2: Just to be clear: I can use the wireless on the laptop on the Live CD, but I want to use the cable because of the greater speed (94Mbit/s on cable 60 something on wireless n, 20 something on g) and because I rarely move the laptop.
EDIT 3: lspci -v shows "Kernel driver in use: r8169 / Kernel modules: r8169", so the driver is loaded.
EDIT 4: So if I boot from the CD. ip addr shows:
eth: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000
link/ether 00:1d:92:...etc... brd ff:ff:ff:ff:ff:ff
And the LED flashes. When I type: "ifconfig eth0 up" it stops, never to light up again and ip addr shows: "eth: <nO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000
Last edited by imtired (2011-09-08 12:36:51)

When you're in Arch, use output redirection
lspci >lspci.out
then boot into Ubuntu or something where you can access the files and the BBS, Of course, don't forget to use a new file for each command output.
The new network config in rc.conf is not that complicated (wired anyway; never used wireless). OTOH I've had issues on two machines where I have to restart the network daemon (rc.d restart network) or rerun netcfg (netcfg eth0) after boot to get connectivity. And I still haven't come to grips with the ip command.

Can't connect to the internet

Ok. so i did a search and didn't come across any other problems like the one I'm having.
Let me start off by stating that my laptop is an ibook g4 bought feb, '06 (yes the apple care just ran out).
I'm having a problem connecting to the internet on my ibook, running through a d-link wireless router. I'm using my imac to connect to the internet currently (which works fine by the way). It also is connected through the wireless router.
My ibook has a strange ailment. I open up Safari and all I get is a blank screen, the page is trying to load but the status bar is going no where and does the same in Firefox. So first, I opened Network diagnostics, but the computer freezes and I have to do a hard shutdown. (holding the power button). Next, I tried Disk utility. Verified Permissions, Repaired Permissions, everything is fine. I tried to Verify Disk, and again the computer freezes, will not let me force quit and I am forced to do another hard shutdown. I do the thing where you hold down some key while you're starting up to get into the disk utility so I can repair the disk. This returns clean as well. I downloaded techtool off of my Applecare disk. Did the tests, everything passes. So what's the deal?? I've tried to reset the pram. I even did the Apple Hardware test, everything passed.
I thought it could be my Airport card? It recognizes that there is an internet connection in the top right corner, I even have great signal strength (mostly because I've tried this sitting right next to the router). But still, I can't connect to the internet. Any one have any ideas? I don't know what else to try! Please help!

so i can't believe i didn't try to connect it directly to the router with the ethernet cord. This actually worked. But it still didn't solve my wireless problem. I'm not willing to let my laptop become a desktop. I'm already wired to a plug b/c the battery is slowly dying and has a life of about 5 minutes. I'm not willing to give up my wireless internet too.
I guess now it's got to be the airport card? how do I confirm this? and if it is how much would a new one cost and can I install it myself??

I put the Bt WiFi app on my iPad Mini and now I can't connect to the internet. Please Help

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

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.

I just downloaded the latest iOS.7 upgrade on my ipad2, and since I can not connect to the internet using my cellular data plan. I have checked my data plan and it's both current and over 2GB remaining. However the indicator shows no service, thus would be the best steps to recover.

Blackberry 9320 can't connect to the internet through WIFI

Dear all
I have problem connecting my Blackberry 9320 to the internet via the wifi. I have tried all settings but still can't connect. I connect to the WIFI but when I try to connect to the net its says can't connect to the internet if the problems continues contact your internet service provider. I had the Blackberry 8520, I could connect to the net through the WIFI easily but with this I really don't know where the problem could be. I really need your help

If it says "Contact your service provider", then i don't think it's a problem with BB's end. You need to contact your carrier.

ITunes can't connect to the internet

iTunes 10.6.0.40 can't connect to the Internet. Affects access to the iTunes store and help, and podcast updates.
Windows 7 Enterprise x64 (fully patched).
Firewall disabled (and I've checked group policy to ensure nothing is being forced)
Antivirus uninstalled (was using Microsoft Forefront).
IE9 LAN Settings - All unchecked.
IE9 Advanced Setting - "Check for server certificate revocation" unchecked
I've run ipconfig /release, then /dnsflush folowed by /renew
I've run "netsh winsock reset" and rebooted.
I've verified my router settings by updating podcasts on an older version itunes on a different laptop on the same network.
I've uninstalled all apple products on my laptop (update, bonjour, itunes), then rebooted, renamed the itunes directory under my profile and even went into my registry and manully flushed out all references to the old itunes path before reinstalling again (10.6.0.40 - that's the only installer I can get now).
None of the above worked. I still can no longer update my podcasts or connect to the iTunes store.

This is bogus.
I have ran AutoRuns multiple times and only have Apple's Bonjour there.
I have run Windows 'Winsock Reset'.
Still I get a blank screen and a 3/4 loaded iTunes Store before it freezes amd crashes.
Next Solution?

Despite troubleshooting, still can't connect to the internet on my Dell Laptop
