El Capitan network problem

I have a macbook pro and the network does not work after an update.

After a lot of research on the web, I discovered that it was inconsistent data of Configuration of Extension Kernel: worm. 3.28.1 that caused the problem, but I tried everything what support suggests and reinstalled El Capitan but the problem remains.

As you can see I have the following

Incompatible Configuration of Extension core data:

Version: Articles 3.30.1

Quiet: Apple

Installeringsdato: 11/04/2016 11.11

If I start in safe mode WiFi/Ethernet work - and then when I restart the Mac it works to- but I can do, to make the WiFi/Ethernet work without the first safe mode boot.

Update the operating system to 10.11.4 should fix.

There is also a small command that you can run in the Terminal to update just the extension of the problem of core - see here:

  • Vista unidentified network problem

    My HP G60 laptop under vista home premium got an "unidentified network" problem and not able to get on the internet. I even tried to reinstall vista to factory default, still the same problem with my wireless router.

    Spec:

    -HP G60 laptop computer, running vista Home premium 32-bit, with 3 GB of RAM

    -Belkin router

    -I am able to connect via a fine wired line but with a Wi - Fi, it shows constantly 'unidentified network', even if I changed the Private mode in network and sharing Center.

    -J' tried the following: listed an SSID different router, reset the router by default, to reinstall vista, tried other mechanisms, such as specified in the forum, with no difference

    -When you configure the router, I have clone MAC of the laptop to the router to get the connection with Comcast, has done that with network cable connected, internet connection worked well after cloning.

    -no virus SW installed.

    Any suggestions on what might be the solution here? Thank you.

    Hello

    It seems that something is blocking the wireless to connect to the wireless router and to obtain a valid IP address.

    Maybe this can help.

    These steps and tell us where is the breaking point.

    Check the Device Manager for the wireless card valid entry.

    http://www.ezlan.NET/Win7/net_dm.jpg

    If there is no valid entry, remove any entry from fake and re - install the drivers for the wireless card.

    Check network connections to make sure that you have a network icon/entry wireless connection, and that the properties of the icon (right-click on the icon) are correctly configured with the TCP/IPv4 protocol in the properties of network connections.

    http://www.ezlan.NET/Win7/net_connection_tcp.jpg

    ------------------

    The wireless card drivers much also install utility wireless of the seller.

    Make sure that if there are teas from Wireless Utility of seller does not work with the native Windows wireless utility (Service WLAN).

    ----------------

    Make sure you firewall No. preventing / blocks wireless components to join the network.

    Some 3rd party software firewall continue to block the same aspects it traffic Local, they are turned Off (disabled). If possible set up the firewall correctly, otherwise totally uninstall and get rid of its remaining processes that permit the own local network traffic flow.

    If the 3rd party software is uninstalled, or disables, make sure Windows native firewall is active .

    party like Hello and NetMagic 3rd network managers can block local traffic too.

    ---------------------------

    Stack TCP/IP work should look like.

    Right-click on the wireless network connection card, select status, details and see if she got an IP address and the rest of the settings.

    http://www.ezlan.NET/Win7/status-NIC.jpg

    Description is the data of the card making.

    The physical address is MAC of the card number.

    The xx must be a number between 0 and 255 (all xx even number).

    YY should be between 0 and 255

    ZZ should be between 0 and 255 (zz all the same number.)

    The date of the lease must be valid at the present time.

    * Note 1. IP that starts with 169.xxx.xxx.xxx isn't valid functional IP.

    * Note 2. There could be an IPv6 entries too. However, they are not functional for Internet or LAN traffic. They are necessary for Win 7 homegroup special configuration.

    ---------------------------------------------------

    A message in the small window that says connected wireless doesn't means that you are really a valid functional connection.

    Above everything is OK, you must be able to connect to the router.

    Connection to the router means that you can enter the IP of the router base in an address bar in one go, being able to connect and configure the router menus see.

    If it doesn't connect to the router, journal newspaper from any computer that can connect to the router wirelessly with a wire, disable wireless security, make sure that the wireless SSID broadcast is enabled and try to connect with no. wireless security.

    Enable security wireless after you eat to make a functional connection.

  • PE2950 intermittent network problems

    Hey guys, I have a PE2950 running Windows 2008 R2. It's a (non-primary) domain controller and I'm having all sorts of problems with replication errors. I also have problems with DNS errors.

    When I log on the 2950 and run nslookup ifc.local, sometimes it comes complete with success immediately. Then if I run it again a few seconds later, it expires. I checked the reverse on both servers search areas and have the correct PTR records (it seems) and points NIC of each server to the other server, and then to his self for DNS. There are forwarders in DNS records, but not on the network card. I seem to have no problem with the PDC network (a 1950).

    It seems that my network problem is intermittent and can be hardware/driver related, but I'm not sure. One thing I found interesting is that if I try to activate IPV6 on the 2950's NIC, I receive an error message that says I need to install a network card in order to configure TCP/IP, but there is clearly a here and IP4 is set up very well.

    IPconfig shows also two cards tunnel I'm not familiar with. Clear that they are not used. I would like to disable some how?

    Here are the results of an ipconfig/all and nslookup example. Of course, when I went to this post, I couldn't nslookup to expire, but when he does I have server: UNKNOWN and IP address correct and therefore three lines of time-out.

    Thanks in advance for any help you can offer!
