Restore Network Settings/Can't Access Internet?

Hello. Really hoping someone can help me out here. Long story short: I had accountability software on my computer and it didn't seem to be functioning properly, so I tried troubleshooting it myself. I couldn't figure out what was wrong with it so I decided to try installing it again. In my haste, I (foolishly?) deleted the program from my hard drive without first uninstalling it. Now it seems to have placed a stranglehold on my ability to access the Internet: every webpage comes up with either "this webpage is not available" or "this website has been blocked by [accountability software]."
What do I do? I've tried running diagnostics and checking my network settings and everything *appears* in order (but I am a novice at some of the more advanced troubleshooting stuff), and I even attempted a command+r reboot last night in the hopes that it would somehow wipe any traces of this program from my computer. Alas, nothing.
Is there anything else I'm forgetting? Honestly what can I do to just get rid of this program and regain Internet access?

Are you able to access the internet while started in Safe Mode ?.
If so, download the uninstaller; or reinstall & use the built-in one, if that's what the developer says is required. There may also be manual removal instructions online somewhere.

3. Microsoft router MN-500:
Tried this old router (the one I used before purchasing the LinkSys). It is an old (circa 2002) Wireless B base station with WEP Security. The iPhone was never able to connect to the Internet using various settings, many of which were duplicates of the LinkSys tests above.
On both routers my wife's Dell laptop and my HP printer connect without incident, using the same network/security settings.
I have always been able to connect to various unsecured WiFi networks; I have never been able to connect to a secure WiFi network (although the only one I've really tried has been my own).
I am at a loss as to what to do next. Any suggestions?

SUCCESS!!!!!
I visited my brother-in-law yesterday and attempted to connect with his secure network. By sheer luck, he is using the exact same model LinkSys router. My iPhone connected first time--so the iPhone was eliminated as a source of the problem.
I didn't do a lot of troubleshooting at his house, but I did notice that his network was set for both dynamic DHCP and dynamic DNS. I know that either or both of Windstream (my ISP) and my broadband modem requires a pair of static DNS addresses.
Sure enough, delving real deep into Windstream's support site, I discovered a LinkSys router DNS help page, specifying how to set static DNS addresses in LinkSys routers. I then accessed my router, enterd the known static addresses, saved the router settings, then rebooted the iPhone and connected to the network.
SUCCESS!!!
Thanks to Jane, who suggested it was an ISP issue, Jason, and all at Apple support. dumonj, I'll email you directly. Try this suggestion and see if it helps.

WRT54G v6 - Can Connect to wireless network but can't access internet

Ok, this is my last resort for help. I spent two hours yesterday with linksys "chat" support to no avail.
First the techincal details:
OS for all machines = Windows XP
Laptop w/two adapters - one wired, one wireless
WRT54G v6 upgraded with 1.00.9 firmware
SpeedStream modem from DSL provider
I have manually set the IP, subnet mask, gateway, primary and secondary DNS for my wireless adapter (using the Alternate Configuration in the Internet Protocol Properties of the Wireless Network Connection). When I connect to the wireless network I see that the IP, subnet, gateway and DNS server IPs are all correct (via ipconfig /all). I see that I am connected to my SSID (11.0 MBps, signal strength Excellent) however I can't access web sites (the server not found message appears in the browser) nor can I ping the router IP or any other IP (LAN or WAN).
My wired PC works fine with this router. My laptop works fine with this router when wired.
Anyone face a similar situation and have a solution? Thanks.

A new discovery...
When I disable the wireless security on the router, I am able to connect to the wireless network, ping the router and access the internet. So, there is apparently something wrong with the WEP security (although I am able to connect to the wireless network when WEP is enabled).
I am thouroughly confused. Any help is appreciated. Thanks.

IPad connected to network, still can't access internet

Hi everyone - I hope someone can help. Starting a few days ago, my iPad (and my iPod Touch) say they're connected to our wireless network, but, when I try to pull up a web page or access the App Store, I get an error message saying that I'm not connected to the internet.
I've turned off Wi-Fi and turned it back on, left my network and re-joined it, shut down the iPad and restarted it, reset all of my wi-fi settings (returning them to factory settings)... nothing's worked.
Anyone know what's happening here? My MacBookPro is working fine on the wireless network... as is my husband's Net Book.
Thanks!
Megan

I tried all the usual fixes - restarting the ipad, rejoining the network, etc., but the only thing that worked for me when my iPad said it was connected to the network but showed no bars at all was this:
Go into your WIFI settings.
Click on the arrow to the right of the network you are trying to join.
Click on Forget this Network at the top of settings.
Go back to WIFI.
Select the network you want to rejoin.
Enter your password.
Once I did this, I was able to successfully join the network again.
Not sure why this was necessary, as my Wifi had worked perfectly with that network previously, but I believe by totally disengaging from the network and rejoining it probably reset the IP address.
Hope this helps someone.

New PC laptop - can get on Airport Network but can't access internet

Just got a new HP laptop for real estate reasons (MLS is only available through a PC).
All of my other computers are Macs and my wireless network is on a Airport Basestation.
I can access the network with the PC but can't get on the internet even though I'm on the network.
Anyone have any ideas?

Ok, you have a completely different situation than that of the Originator of this post. In your case, you're using your Mac as a software base station and not a wireless router.
The following would be the setup steps...
To setup for Internet Sharing (Wired to Wireless):
Enable Software Firewall
System Preferences > Sharing > Firewall
- Click Stop to start the software firewall
Setup the Network
Cable Modem > (Ethernet cable) > [Ethernet port] Mac > (wireless) > PC
Setup Port Order
System Preferences > Network > Show > Network Port Configurations
- Verify that "AirPort" and "Built-In Ethernet" are enabled.
- Verify that "Built-In Ethernet" is at the top of the list, followed by "AirPort".
- Click "Apply Now."
Configure the Internet Connection
System Preferences > Network > Show > Built-In Ethernet > TCP/IP
- Configure IPv4: Using DHCP
- Configure IPv6: Automatically or Off
Enable Internet Sharing
System Preferences > Sharing > Internet
- Share your connection from: Built-in Ethernet
- To computers using: AirPort (checked) (Note: Uncheck all other entries in the list.)
- AirPort Options
-- Network Name: <anything you want>
-- Channel: Automatic
-- Enable encryption (using WEP) (optional)
-- Password: (optional)
-- Confirm Password: (optional)
-- WEP Key Length: (optional)
-- Click OK
- Click Start

New Ipod Touch 5g can't access Internet in home network (using Linksys E4200 router). But, OK with other Wifi.

Just bought new Ipod Touch 5g. I found out it can't access Internet in home network. not really cannot access, but very slow to open any web page, App Store failed to access, etc. But, OK with other Wifi (office & starbucks). Others existing iOS devices (Iphone4 & Ipad2) have no problem like this. I'm using Linksys E4200 router at home. anyone has any idea why?

Try:
- Reset the iPod. Nothing will be lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router
- Reset network settings: Settings>GeneralReset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup
- Restore to factory settings/new iPod.
- Make an appointment at the Genius Bar of an Apple store.

My MBA indicates my connection is timing out. My wifi on other laptops work in the house. Diagnostics indicate wifi settings failed, network settings failed, ISP failed, Internet failed, and server failed. What can I do?

My MBA indicates my connection is timing out. My wifi on other laptops work in the house. Diagnostics indicate wifi settings failed, network settings failed, ISP failed, Internet failed, and server failed. What can I do?

Take each of the following steps that you haven't already tried, until the problem is resolved. Some of these steps are only possible if you have control over the wireless router.
Step 1
Turn Wi-Fi off and back on.
Step 2
Restart the router and the computer. Many problems are solved that way.
Step 3
Change the name of the wireless network, if applicable, to eliminate any characters other than letters and digits. You do that on your router via its web page, if it's not an Apple device, or via AirPort Utility, if it is an Apple device.
Step 4
Run the Network Diagnostics assistant.
Step 5
In OS X 10.8.4 or later, run Wireless Diagnostics and fix the issues listed in the Summary, if any.
Step 6
Back up all data.
Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
Enter the name of your wireless network in the search box. You should have one or more "AirPort network password" items with that name. Make a note of the name and password, then delete all the items. Quit Keychain Access. Turn Wi-Fi off and then back on. Reconnect to the network.
Step 7
You may need to change other settings on the router. See the guidelines linked below:
Recommended settings for Wi-Fi routers and access points
Potential sources of interference
Step 8
Make a note of all your settings for Wi-Fi in the Network preference pane, then delete the connection from the connection list and recreate it with the same settings. You do this by clicking the plus-sign icon below the connection list, and selecting Wi-Fi as the interface in the sheet that opens. Select Join other network from the Network Name menu, then select your network. Enter the password when prompted and save it in the keychain.
Step 9
Reset the System Management Controller (SMC).

Airport extreme guest network can't access internet

I upgraded to the 7.6.1 a few weeks ago and recently noticed some oddities, My guest network clients get an IP in the 10.x.x.x network but can't access the internet, the private network is just fine. I looked on the airport utility for any advanced wireless options to indicate setting for the guest but I didn't see anything.
Is this the desired method of operation? My private network is using the 192.168 network, do I have to set my GUEST network to the same range in order to get out with it?
I use a lion server on the network that is also giving out IP via the Lion DHCP Service, is there some other change I need to make to the Airport Extreme to have it forward the Guest network dhcp requests to the Lion Server?
Any help would be appreciated.
Mike.

Turns out when I set my DNS server IP for my APE DHCP to my Internal IP on my Lion server, the Airport Extreme is not allowing those guests to talk to my DNS Server so I updated the DNS to be my external/Public IP and now the guest network can do DNS and access all the cool stuff on the internet.

I installed a new airport express and made it part of my existing home network... now the PCs can't access internet through the airport extreme or the cisco access points

Everything works perfect with Macs, iPhone, iPads but I have 2 pcs that now can't access internet. The PCs connect to the airport and my other access points but no internet- The PCs sent an error of DNS

Yes, as we already said, it will do all of this if you have a good wireless signal reaching the bedroom.
Remember that an extender or repeater or whatever you want to call it can only extend the quality of signal that it receives.
The Ethernet signal that the Express delivers will only be as good as the quality of the wireless connection between the AirPort Extreme and AirPort Express.
If you have doubts, make sure that you understand the store's return policy before you buy.

IPhone 5s can connect to wireless WIFI router but can not access internet.

iPhone 5s can connect to wireless WIFI router but can not access internet at work. The admin says the router lets my iPhone connect to LAN, but the iPhone does not have server IP to access the internet. I entered the server IP and port number in the HTTP PROXY fields but I still can not access the web. Any ideas?
TIA
Rich

You IT person should be able to sort this out. But, they seems to be too busy or disinterested to do this. Suggest you provide the it person with an iPhone to get interested.
Any could be lots of things.
The best you can do is to get access to the admin setup for networking on a pc? The internet settings are all the same. Only what names the manufactures change from OS to OS. Check and compare parameters.
Phone works to internet at home, I assume?

I recently when to England. When I returned to the US, my iPhone 5 wouldn't find the 4G network. I've tried restoring network settings, I've tried hard resets. I finally wiped the phone, and now, it won't let me restore anything. Help!

I recently when to England. When I returned to the US, my iPhone 5 wouldn't find the 4G network. I've tried restoring network settings, I've tried hard resets. I finally wiped the phone, and now, it won't let me restore anything. I'm kind of stuck - this is both my personal and my work phone, so I'm really in a bother here. Help!

I had "do not disturb" on in England. I did take it off airplane mode periodically, but I never actually used the network. I stuck to local wifi to do brousing and a bit of messaging. It periodically told me I was on an English network, but I didn't actually use it. And I had data roaming shut off all together.
when I try to restore, I get this message:
Your iPhone could not be activated because the activation server is temporarily unavailable. Try connecting your iPhone to iTunes to activate it, or try again in a couple of minutes. If this problem persists, contact Apple Support at apple.com/support.
When I try it through iTunes, I get a similar message.
and the network just keeps saying, "Searching..."

"Use iTunes to restore". How can I access the iPod w/o losing present data?

I have a request from my grandaughter to download a number of songs to her iPod. I charged the battery fully. When I tried to start it , it read "Use iTunes to restore". How can I access her iPod w/o losing any of her present songs? Please please help.

You can't. Restoring will always erase the device. Unless you have a backup in iTunes or iCloud everything is removed. Purchased items can be re-downloaded as long as the original Apple ID used to purchase them is also used when reconfiguing the device after it is restored.
Downloading past purchases from the App Store, iBookstore, and iTunes Store

After restoring original settings can phone numbers be retrieved

after restoring original settings, can phone numbers be retrieved?

You can sync them from the computer to the iPhone using iTunes.
You could also restore the iPhone from backup.
