    hi everyone, I'm new her and wondering if someone can please help me.

    When I am at work out at sea we use the wifi on board for internet connections. I have never had any issues with getting online with any of my devices, as well as my MacBook Air. I arrived back here two days ago and I have no issues connecting to the network and Internet with my mobile phone and my iPad but for some or other reason I can get onto the network with my Mac but get no internet access, but if I start up in recovery mode I can access the Internet. Here are a few things I have tried to no avail.

    • Rebooted computer numerous times
    • Forgotten network and rebooted
    • Tried using various Internet browsers like Mozilla, Safari and chrome
    • Disconnected my VPN
    • Started in recovery mode and once in safari I can access the Internet.
    • Tried to connect through my seagate wifi hard drive as a hotspot.
    I am not the most clued up on computers so not sure what else to try, I would really appreciate any help from anyone. I originally thought that the server might have blocked my I.P address after using a VPN in the past but if it was blocked then how do I access it in recovery mode then?

    try finding out what the DNS entries are on the boat using DHCP (system preferences->network>select WIFI->advanced->DNS>. You could always try hard coding your DHCP address/DNS servers and see if that makes a difference. OPEN TERMINAL and try to PING your default gateway, DNS servers. If you can't PING either - bigger problems.

    Thanks for the reply but this is all a bit Greek to me unfortunately.

    If this used to work and all of a sudden doesn't, well somebody did something. Speak to person who setup this WIFI/LAN. If unable to look under the hood yourself well I guess u gotta call somebody/professionals.

    I've found that deleting "Wi-Fi" in System Preferences-Network fixes a lot of problems. Then you can set wireless up from scratch.

    Next to try would be to remove the VPN software as some has been known to corrupt TCP/IP even when not running.
