WiFi or Ethernet do not work!

I Have a Macbook and the Wi Fi or Ethernet will not work. I renew DHCP lease and the internet works for 10 seconds than I have to renew it again. I have 2 more Macs and they work fine. I have two routers and this computer has the same problem with both. Is there a way to solve this?
I have notice that a lot of people have had this problem has anyone resolved this issue.
So far this is what I have tryed:
Macintosh> Library> Preferences> SystemConfiguration (deleting all documents in this last folder).
-reseting router
-Macbook Software update
-Flush DNS cache using Terminal (dscacheutil -flushcache)
-holding Command+Option+P+R during restart until hearing another chime
-airport on/off
-removed airport and added again from Network Preferences
-Network>Advanced (deleted Preferred Networks and also from Keychains)

I had to convert the official ISO before it would boot happily as a USB on my used Air I've just got, I followed the instructions at https://wiki.archlinux.org/index.php/UE … B_from_ISO including the suggestion below to use rEFInd instead of gummiboot and it worked for me.

Wifi and ethernet are not working

Hello guys,
I'm using Mac Mini (Latest 2012) on OSX Mavericks and having a problem with my internet connection. Somehow it just didn't work, the internet connection works perfectly on my iPhone and my Android.
I already tried to reset the network setting that has been discussed many times but simply didn't work on me.
When i use ethernet and wifi connection it always showd yellow dot on 3 bottom criteria on diagnostics.
Can anyone please help me?

It's not clear whether you tried an Ethernet connection alone. If you do that be sure to temporarily disable Wi-Fi to eliminate confusion.
Apple's Wireless Diagnostics may supply some additional helpful information.
To use it, hold an option key while you click your Mac's Wi-Fi icon, and choose Open Wireless Diagnostics...
The following authentication dialog will appear:
Authenticate with your Admin password, then click the Continue button in the following:
The network analysis and diagnostic tests will take several minutes to complete:
When it completes, if your wireless network is functioning properly the following will result:
If something is amiss, supposedly the results will be different and you will be presented with helpful information.
Assuming your connection is "working as expected" select Continue to summary and click Continue:
Ignore the pre-populated text field, which is provided as a place for you to type in additional information should Apple ask for it in the course of obtaining technical assistance from them. Apple has no way of knowing where your router is located in your home, and certainly doesn't know if you even have an upstairs bedroom closet.
Click Continue.
The next step will also take a few minutes:
When it finishes, you will be presented with a summary that may or may not be useful to you:
The above result is uninteresting, but if there are additional actions for you to consider they would be included in the screenshot above.
The WirelessDiagnostics-xxx.tar.gz file deposited on your Desktop can be dragged to the Trash, or you may wish to expand it and examine its contents. It's up to you.

Bridging WiFi and ethernet cards not working

My setup is that I have a laptop with both a wifi card and an ethernet card that can connect to the network via wifi. I also have a desktop with no wifi card that I want to use on the network. I have the two connected via an ethernet cable. I want to bridge the wired and wireless connections on my laptop so that my desktop can be on the same network. When I do this, however, problems arise on the wifi. According to iwconfig, it can connect to the network, but when I run dhcpcd on the wireless interface it times out on waiting for carrier. The bridging in WIndows works fine, but I'd rather not reboot just for this task. Does anyone know a solution to this problem? I am running a bcm4312 wifi card if it helps.

Internet sharing from Wifi to Ethernet is not working after Mountain Lion upgrade

First I was having trouble just connecting these two, now I can't get the Internet sharing to work. Here's what I am trying to do: I want to share my Macbook Pro's internet connection from it's Wifi to another laptop I have connected via ethernet cable. They will ping each other now. The problem now is that the laptop won't pick up the Internet connection from the Macbook Pro, even though I have it configured exactly as I had in Snow Leopard. Nothing has changed on the laptop from before when it worked fine with Snow Leopard. But now that I updated to Mountain Lion, Internet sharing no longer works no matter what I try. I've been trying to find a solution by to no avail. Could anyone here offering some advice or a solution that will fix my problem? I've been over the basic steps over and over again, so please don't ask me to do something stupid like reboot or check the Sharing settings. They're exactly how they are meant to be, but the thing just won't work.

Ran a TCPdump on my Macbook Pro. It is recieving the ping requests, but the laptop still isn't getting replies to its pings. So something is wrong in the Macbook's configuration somewhere. I don't know where, though.

I have installed the agent 10 or 15 times and one installation has failed, no error appeared during the installation but I am having inconsistent issues with my ethernet card not working here and there. We rebooted and can log into Novell client but the login prompt did not appear for ESM client or the icon was not in the systray. Everything seems to work, besides at times (a couple times today) it terminates his ethernet card/connection. I would re-image his computer but he has several applications and it would take several hours, so I am hoping someone has an idea to fix this issue. So I was trying to figure out why he did not get the prompt to login and why it's not in the systray and it appears to not have completed the install? I checked the add/remove programs, its not listed within their, I also checked the registry and found nothing for endpoint within their, but the files are within c:\program files\novell\zenworks endpoint security.
I have also tried uninstalling it but that fails due to it "not being installed", and it will not reinstall over itself either.
I did notice that stuninstdrv.exe is running in task manager. Any help would be great...

If you are searching the registry, check for the "Senforce" string. It should be at HKLM\Software\Senforce
Try running the install program for the ZSC with the following command line:
setup.exe /V"STUNINSTALL=1"
If you've specified an uninstall password, try this one instead:
setup.exe /V"STUNINSTALL=1 STUIP=password"" (please note the double quote at the end)
Let me know if that helped you.

X240 F8 Wifi function (fn) key not working

Hi guys,
Just wondering if you guys have the same problem with the F8 wifi switch function key not working?
The F8 function key only works if I have the "Network" page opened on the right hand side (by clicking on the network logo on the task bar). It doesn't do anything if I just press it without that network page out.
Is it suppose to do that?

Hi Tomlaulau,
Welcome to Lenovo Community!
I’m sorry to hear that you are facing the issue with Wifi on ThinkPad X240.
This kind of issue occurs when there is error in the Power Management application. Hence we request you to check with updating the Power Management application from the drivers page.
If your system is installed with Windows 7 OS, then you have to install both Power Management and Power Manager Application.
Below is the link to enter the downloads page and install exact Power Management application accordingly, please click on "Select Product" then in "QUICK PATH" enter the MTM no. select the exact model.

Hope this helps. Do post back if issue persists!
Best regards,
Hemanth Kumar

HT6146 my wifi and bluetooth is not working what sholud i do

when i upadte my iphone 4 in ios 7.1.1 my wifi and bluetooth is not working
what should i do ?? :(

What doesn't work?
What problem are you having?
Remember for the iPhone to see and connect to Bluetooth devices they must be in, "Discovery Mode".

TS1559 Wifi and bluetooth is not working on iOS 7.0.2

Its disappointing to see crazy bugs even after a .0.2 release. All the work rounds fail

I Am IT support for a large Company also using iPhone 4s. I can confirm this issue as employee's start upgrading to iOS7.0.2 Bluetooth and wifi working fine on iOS 6.x as soon as upgrade to 7.0.2 Wifi Toggle greyed out, No wifi MAC address, bluetooth not working.
Have tried all suggestions on various forums to no avail .
Even a DFU recovery and set up as a new iPhone failes to fix the issue.
Have advised users if they have this issue to return the phones to Apple.
Also discussing with Other IT collegues in company to send out a bulletine asking employees NOT to upgrade to iOS 7 at this stage.
Whilst my company iPhone upgraded fine, it would appear not all do. I suspect different versions of the WIFI and Bluetooth hardware would be the cause of this issue. This would explaine why some upgrade ok and others do not.

I am using iPad1. Running v4.3 and when connecting to wifi iPad keyboard does not work. Keyboard works for everything else including typing this question out. Why would it not work when typingin password for wifi connection?

Lots of WIFI needs a username and password to get access. I guess you're lucky and yours is set up unsecured.
Normal secured WiFi requires only a password to get access. The password is used to encrypt traffic between your device and the WiFi access point. If whatever you are using requires a username as well then it is not simply normal secured WiFi. It might be a subscription WiFi service like GOGO, ATT, etc., or a service with authentication, i.e., college campus, etc. To help you out we need to know what you are using and what connection dialog you are being presented with. You don't have exactly the same problem as the original poster. He is having a problem entering a password into the password dialog that iOS presents when one tries to connect to a normal secured WiFi network. Could you clarify exactly which WiFi service you are using.

MacBook Air wifi internet shared network not working on tethered android phone GT B5122

MacBook Air wifi internet shared network not working on tethered android phone GT B5122
I have created a password protected wifi internet network on my Macbook air. I tethered by Andriod phone onto this network, but the internet connection works intermittently on the phone, and when it stops working the network continues to show as connected to the shared network mostly(other times it keeps renewing the wifi IP address on the Andriod phone).
Also the network the MBA is connected to, is a hardwired one using a SSH login account in a student accomadations.
I am not sure, but all the restarting and refreshing of system, phone and wifi sharing and re-enabling wifi is not reparing the internet connecting on the wifi network for the phone
Really puzzled, if this is one of the Apple, Andriod compatability issues.
Cheers,
Vivek

Hi.
I'm having trouble with the wireless connection on my new home hub 3. Most devices will connect easily, but there are three devices that have trouble connecting. These are an Android Phone (Samsung Galaxy Mini), an android tablet (Sony Tablet S) and an iPod. All of these devices work perfectly on other network connections, and other devices in the house are quite happy connecting to the network.
The Androids can see the network, and will try to connect to it, but when they do they just go through a loop of "connecting">>"acquiring IP address">>"disconnected". I have tried resetting the Home Hub with a pin, and that lets the devices connect for about 24 hours, but after that time they stop connecting again.
I'm really not sure what to do to fix the problem, so I will very much appreciate some help.
Many Thanks.
My lads SGMini connects perfectly to our hub3
Have you installed the BTFon app to these devices?
If so, you could delete it and then see what hapens.....

Tap Settings App > General > Reset > Reset Network Settings. See if fixed. If not, Restore Firmware with iTunes on computer. See if fixed. If not, all iPhone 4S have Warranty, make Genius reservation and take iPhone to Apple for resolution.

If you are sure that your password is correct try restarting your router by removing power to it for 30 seconds and restarting. On your iPod go to Settings > General > Reset > Reset network settings. Now try to connect.
