With the GDPR deadline set for May 25, 2018, many organizations are ill-prepared due to uncertainty about the criteria for compliance. According to a recent WatchGuard survey, a staggering 37% of respondents don't even know if their organization needs to comply with GDPR. Do you?

No laptop WiFi internet, while local LAN works fine
Posted on 2013-05-25
I cannot connect to the internet with my WiFi. Connecting to the local LAN works fine. I have already tried the ipconfig /release ... /reregister sequence, but no luck. My ipconfig is below. Any ideas?

Provided your laptop wi-fi is enabled, can you see your LAN on the available networks menu?
If your wi-fi is not enabled, try the hot keys first to activate it.
Seems your DNS server is set to your server. Perhaps your network settings do not allow you to access the net? Anyway to confirm this please?
Also, log in to this computer if on windows and see if you can scan for your network wi-fi connection. Try to connect and see.
Also, does your wi-fi work outside your office? Just asking for info.

Additional info: The wireless connection says "Limited" if no Ethernet cable is also plugged in. When I plug an Ethernet cable into the wired port the wireless connection no longer says :Limited", so there is probably some additional information that is made available when the laptop is also hard-wired. Strange, because all local LAN connections with wireless seem to work fine.
I'm running Windows 8.

The Wifi is connected and enabled and works fine on the local LAN which has dozens of hosts. It just fails to make the jump to the internet.

192.168.1.12 - what is this?
Your DNS primary server is the above address - so that's where the issue lies since you can't get to the outside...
Is this a Windows server of some sort? If so what version? 2003/2008?
From laptop when you ping using this command what is returned
ping 8.8.8.8
If you get 'Reply from' then you are connected and the issue is DNS...if you get 'Request timed out' then we've another problem to look at...

The machine at 192.168.1.12 is indeed the DNS server and it is running Server 2008 R2, Service Pack 1. This machine works fine as the DNS server when I have an Ethernet connection, but not when I'm running only WiFi.
New info:
I just unplugged the Ethernet cable (so I'm running only with Wi-Fi) and now it works. This is bad. An intermittent problem is the worst. The next time it behaves poorly I'll ping 8.8.8.8, but when I tried pinging Microsoft.com before, it said "Request timed out". Now everything is working as expected, except that for hours it wasn't and I didn't change a thing.

Ok, depends on what config you have on your LAN ethernet card...I see from the output above its set to
DHCP Enabled. . . . . . . . . . . : No
Which means its got a static ip I would assume...what DNS entries are in the ethernet card currently?
Wifi is set to DHCP so its getting 192.168.1.12 from that...check your ethernet settings on the wired connection to see what DNS entries are set...

Both interfaces have the same DNS (192.168.1.12) set statically (not from DHCP). Real problem is that it is apparently intermittent ...

Normally I setup DNS Forwarders on the server to eliminate resolution issues...
Go into DNS Console in Control panel - admin tools on the server
Right click server name - properties
Go into Forwarders tab
Enter your ISP's DNS server ip's in there, plus others if you want
Some people add in OpenDNS's server ip's - 208.67.222.222 & 208.67.220.220
Click ok to close console...
Now public resolution should happen quicker...might the one of the causes of the problems...either way this will help things in general
