Just updated MacBook Pro, connect to WiFi, but unable to open any of the downloads, Just updated MacBook Pro, connect to WiFi, but unable to open any of the downloads

I just updated my MacBook Pro with the latest release of Lion. Now I am unable to open downloaded content. I have no trouble connecting to WiFI.
Any ideas?

What is the prompt that comes up when you try to open a downloaded file? Where did you download the file from? What kind of file is it?

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 before proceeding.
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).

I just secured my WiFi with a WEP password. I can connect my MacBookAir and iPhone, but not the MacBook Pro (MBP using Lion-MBA Mountain Lion, iPhone iOS6

Using a DLinkVWR (Vonage enabled) router, I just secured the home WiFi with a WEP password. No problem in establishing a WiFi connection on my MacBook Air (OS Mountain Lion 10.8.2) or with my iPhone using iOS6. They both accepted the password and connected directly.
Not so with my wife's MacBook Pro, using the latest version of Lion, 10.7.5. It can find the WiFi, but upon attempting to connect, the alert is shown that there is no internet connection. This is unique to this MacBook Pro. The drop down menu shows the router checked and 4 bars, but the Alert remains: No Internet Connection.
What am I doing wrong? This MacBook Pro connected without problem before I secured the router.

WEP as a security measure is laughable nowadays. Even a kindergarten kid with a netbook can crack the password in a few minutes. Try using WPA2 if available on the device. And the Macs will be quite happy connecting with that protocol.

Lion mountain newest update :I loos the internet connection, but the network shows connected. And IPhone, IPad stay connected and work. Only the MacBook Pro , which worked perfectly before with Lion unless I updated to Mountain. I have tried everything.

I have a MacBook Pro, Early 2011, 2 GHz Intel Core i7 which I udated some days ago with Lion Mountain 10.8.2. Before it worked just perfect. Now, since the update, I loos the internet connection after a wile, (at the beginning every 20 sec, now up to 4 hours) even that the sign of the WiFi network connection shows to be perfectly connected.
My other divices like IPhone, IPad stay connected and work. The rooter is new and cannot be the problem. I tried nearly everything I found on the bloggs, but nothing helped actually. It must be a softwear problem on Lion Mountain, what can I do?
Thanks for any help

I FINALLY SOLVED THIS ISSUE!!!!
New routers have "mixed" modes for your network; this means that it will automatically choose the best option between wireless-B, wireless-G and wireless-N network modes. I used to experience this issue using the 2.4 GHz. mixed mode wireless network.
Thankfully, my router can create 2 networks: a 2.4 GHz. network and a 5 GHz. network.
When I randomly changed this value to "use only wireless-B and wireless-G" trying to fix an issue with a wi-fi expander, the iMac wi-fi issue dissapeared! I tried it with wireless-N only, but it didn't work.
So, finally, I have a 2.4 GHz network with only wireless-B and wireless-G modes which works PERFECT with the iMac, and a 5 GHz. network with a mixed* wireless mode for everything else mode.
*PD: by "mixed" mode it means that the router will automatically choose between B, G and N network modes as it fits better.

Macbook Pro 10.7.5 internet will not work. HELP!!! Ethernet and WIFI both say connected but still no internet.

I have a macbok pro running 10.7.5. My internet has always worked on it but I decided to try changing my router set up - the set up didn't work so I reverted back to the original setup that had previously worked.
Now, I have an Imac running tiger - I can connect to the internet via WIFI or Built In Ethernet with no problem.
When I try to connect to the internet on the Macbook Pro running osx 10.7.5 my internet will not work
Safari Says (You are not connected to the internet) and Google Chrome says (Page is Unavailbe) and lists some trouble shooting options that I tried.
When I go to System prefrences > Network my WIFI and Ethernet both say "Connected" and have a green light next to them.
I have tryed deleting the connections and starting new ones and I have even tried deleting the Location and starting a new one.
Nothing works - no matter what I do, even know the WIFI or ETHERNET says Connected, the internet will not work on the Macbook Pro.
The Internet works fine on my Imac and I have tried everything such as swaping cables but there doesn't seem to be a problem with my internet
or with my router - it all works fine with my Imac running Tiger.
Can anyone help me get my internet working on my Macbook Pro again? Any ideas?

Hello ASGR.SYS amd WahWar,
I tried both of your suggestions and neither of them worked.
ASGR SYS - When I tried it your way i got a message saying that the that the diagnostic couldn't repair the problem. It shows the thw WIFI, WIFI SETTINGS, NETWORK SETTINGS, ISP, all turn green. But the Internet and Sever stay red. The thing is, there is nothing wrong with my internet connection as I can connect to the internet on my Imac running tiger, both through ethernet and wireless. When I go to System Prefrences and Ntwork the WIFI and ETHERNET both say "Connected" even know I can't veiw any websites.suggestion
When I tried WAHWAR's suggestion I get a message that says cannot connect to the WIFI network and then it lists your typical trouble shooting tips. Like Make sure you entered the right password and make sure you are in range of the wireless network
Again, just to confoirm - My internet connection is working fne both the WIFI and the Ethernet. When I use it on my IMAC running tiger, everything connects as it should and it works perfectly. But when I try to connect with the MacBook Pro, Even know the connections in the Network settings window show up as "connected" the MacBook still seems to think that my internet connection isn't working at all.
I have tried creating new connections, creating new locations, and I have even gone as far to reset my router and start completely from scratch. The result so far has been the same - the IMAC running tiger will connect - my blackberry and iphone will connect - but the macbook pro running lion will not connect..
I'd apprechiate any other suggestions

I own a 13-inch MacBook Pro and for the past day, my wifi on my laptop says I only have two bars of connection and is running very slow,but all of my other devices such as my iPhone and iPad are connecting perfectly to the wifi. How can I fix this? I have tried to shut my laptop off and let it rest and I have also re-started my wifi router three different times. Someone please help me with this problem so I can begin to use my laptop again as I take it to school and use it for class.
Thanks so much!

FCP, and all software on OSX, has a few different "preference" files (the extension is .plist), which store all your user settings. Each time you resize a window, change a setting, anything, this file is re-written. Kinda easy to see how they would become corrupt every now and then.
-Close FCP
-Navigate to User>Library>Preferences and delete com.apple.FinalCutPro.plist
-Navigate to User>Library>Preferences>Final Cut Pro User Data and delete Final Cut Pro 5.0 Prefs
-Empty your trash
Relaunch FCP and see if that worked.
Download FCP Rescue to make this process easier in the future. When you have FCP running really smooth, open FCP Rescue and create a backup of your preference files. If it starts acting wanky, just run FCP Rescue and Restore your backup preferences. Works really slick, and it's free.
EDIT: Or use the really simple explaination that X posted as I was typing.

My macbook pro is connected to wifi but it will not connect to the internet.

My macbook pro is connected to wifi but it will not connect to the internet. When I go on safari, it says that "Safari can't verify the identity of the website". Then I tried to update flashplayer but you need the internet to update it. All this only started happening after that Moutain Lion software was downloaded onto the laptop. Please help, I have been internet-less for a couple months now.

Hi rynhelp,
If you are not able to connect to the internet after installing Mountain Lion, see this article for information on how to start troubleshooting:

My iPhone 4s will not connect with my home WiFi network. I have ios6 on my phone. I have updated my IMac and my MacBook Pro with iOS 10.8.2. Anyone have any suggestions? It was connecting with no problems prior to updating my two computers.

My iPhone 4s will not connect with my home WiFi network. I have ios6 on my iPhone. The connection was working perfectly before I updated my IMac and my MacBook Pro to ios 10.8.2. I have had ios6 since I purchased the phone a couple of months ago. It searches for a network and finds them, but when it asks for my password, it will not accept the password. Have never had this happen before.

I got my first Mac 2 weeks ago, a Macbook Pro. I can't get it to scan on my HP Laserjet1217 nfwMFP all in one. It prints (wirelessly) just fine. But when I try to scan, it says something like "no scanners available". Wireless or connected, it's the same.

I have not been able to get my new Macbook Pro to scan, either wirelessly or connected, with my HP Laserjet all in one M1217 nfwMFP printer. It prints wirelessly just fine, but if I try to scan, I get the message that no scanners are found. The guy in the Apple store had it scanning just fine with a new HP printer he took out of the box. Any ideas would be appreciated.

I would check with HP. Your scanner may need a firmware update and updated HP software. Start here:

My MacBook Pro will connect to WiFi but will not work in one location but will at others. I have the same issue with my IPhone 4S at the same location.

My MacBook Pro will connect to Wifi at one location (this is a secure location) but will not allow access to the internet. I will put in the password but will not display page. Other wifi capable devises do not have this issue but my Mac and my Iphone 4S will not work. I have tried restarting the router. All other wifi locations I have been to have not had this issue. Any suggestions? I am realtively new to Apple products (less than a year) so any advise is greatly appreciated.

The other devices that are working got on with the same password. It says it is connected. Just nothing works on the internet.

When i open my macbook pro the wifi connect but says no internet connection

Every time i close my Macbook Pro (early 2011 model running OSX Lion) then open it back up the wifi will connect to the right network but says i have no internet connection this lasts for about 5-10 minutes then the internet will finally work. i know it's not the router cause im connected on my phone and on other computers and they work just fine. is this something internal or something with the software?

Hi..
Try Resetting the System Management Controller (SMC)

Macbook Pro connected to wifi, but no internet connection

Hi,
Just bought new Macbook Pro yesterday with Mountain Lion OS. When back home, trying to connect internet, unfortunately safari would always says "No internet connection". I try very hard on getting it up creating new connection on MBP but it still give the same result. So I think it should be related my router setting. The current wifi setting for my TP-Link router is WPA2-PSK, AES, channel 11 with secured password. When I changed it to NO security, supprisingly the connection is now OK and I can browse internet through Safari. The problem is I have to get it back to WPA2 security setting since my home internet is now open to my neighbourhood and of course it shouldn't be shared all around you. Anybody can tell how the router setting should work with MBP, with details on security type, AES or TKIP,CHANNEL?

That doesn't mean anything. You can't telnet to google. lol
The ping you did above shows you that Internet access and DNS is working fine. If it wasn't, you wouldn't be able to get replies. This means that the problem is with your browser. Open up Safari and hit Safari/Reset Safari under it's menu. See if that works to solve your issue. If it doesn't, then it's a plugin or something else (maybe Proxy changes, etc.) which could be causing this. One option you have to test is if the reset doesn't fix it, install another browser (you'll need to download the dmg via another PC and install it on the mac from a memory stick or something) and see if a 3rd party browser works.

Until the MacBook Air was released and supported in 10.5, the Mac did not consider USB to be a valid Networking Protocol. So set the Mac with USB solutions aside.
To connect computer-to-computer, you typically need to be using an Ethernet crossover cable. Assigning the same address to two Ethernet devices is never the solution -- it gives a Network Conflict, just as you said.
If your Windows box has some mechanism for Sharing its WiFi connection over Ethernet, you would have to follow its rules. Whether that means Manually assigning an Ethernet Address in the same range or the PC will provide the Address, I do not know.
Best success may be running an Ethernet cable to your Wired/Wireless Base Station, or using a "gaming adapter" (Ethernet-to-Wireless no drivers required) connected to the Mac's Ethernet port to give it WiFi access. What is your Base Station {Cable, DSL, FIOS, Other} ? Ethernet cables can be up to 100 meters (an American Football Field). Often the Base Station can be moved closer for more convenience.

TS1702 Supercam Pro update.Just downloaded update 24-05-2013 and now cannot connect to DVR.Entered correct http address but not connecting,anyone else having same problem?

The OP is correct, I have done many tests. With IOS6 there appears to be a dns issue in some cases with IOS for both ipad(2) at lease (my wife won't let me upgrade here v1) and the iPhone4s in my case. Pretty easy to diagonse, I wish Apple would fix it.
1.) I use a Juniper 5GT wireless firewall and all of my other devices (many apple, ipad, MBP, iMAC,3 ipods etc) are fine: Not ipad2 or iphone4s running IOS6
2.) after upgrade nothing worked. narrowed it down by messing with dns (I have my own dns server)
3.) Strange thing; dns works over MiFI (Verizon) and Carrier
4.) confirmed that it is a dns and not network issue.
-down load free tool called ping-scope-lite. (obviously you need to turn off wifi to do this)
http://itunes.apple.com/us/app/ping-scope-lite/id431500107?mt=8
turn on wifi
- ping Level3 dns server 4.2.2.2 or Googlesdns servers 8.8.8.8 or 8.8.4.4 these worked.
-now ping by name google.com or ipchicken.com
- try others; same result.
Apple did say that they would give me another iphone 4s: I just wasn't sure that would fix my issue. I tried downgrading to 5.1.1 but I got an error saying my device wasn't able to do so (tried even blocking itunes from contacting Apple) I whis this could be fixed. I did even have it working using my own dns server but now I can see that my phone over wifi isn't even trying to make a dns request now.
Stuck

IPad won't connect to WiFi network, but macbook pro & iphones will.

Both of my iPhones and my Macbook Pro easily connect to the wi-fi network. I feel like I've tried everything to get my iPad to connect. It used to connect perfectly fine and I'd watch Netflix, but then it started crashing. I work for a non-profit so it's a company network, not my personal one, but it's the only network I have considering I live here! Such a pain!
I've reset my network settings.
I've click "Forget Network"
I've done a hard reset of the iPad multiple times.
NOTHING WORKS.
Can some super tech savvy person help a girl out?! I would greatly appreciate it.

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 drooping 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.
