Hello,

I can't access Facebook on my laptop or mobile phone. Earlier today I could, on both, however in the last few hours whenever I attempt to log on, I get an error that says site can't be reached and that connection has timed out

Hey Guys,

I was able to solve this issue. It turned out that the DHCP service on the server had a bad scope. I removed the scope that was in there and also added an exclusion range, which was important to have. Once I added the new scope and activated it, I was then able to get access to the internet wirelessly.

Thank you all for your input.

I tried the forwarders and that didn't work. I put in all the public DNS that were recommended, 8.8.8.8, 4.2.2.1 and 4.2.2.2. I think the DNS component of the server might be corrupted. I was thinking of removing the DNS entirely and re-add it again on the server. This server was added to an existing forest, so I think some of the DNS properties from the old server is still playing a role somehow. The old server has been taken down.

If I deleted the current DNS settings and configured a new one, would that make a difference? Somehow I think it will. However, Im not sure what the consequences of deleting the current settings will be.

Also, I noticed when I connected my laptop to the Wi-Fi and statically assigned the DNS server (192.168.0.3), it was then able to go out the internet. The connection was kind of slow, but it still went out to the internet. That made me think that the DNS settings might be corrupted.

Regarding the nslookup, I was working with Ubiquity support exclusively for a while, as I thought the issue was with them. They ran a couple of NSLOOKUP commands and saw that the AP was working fine with DNS. They concluded the issue is with the DNS server.

I will try that NSLOOKUP command from the server and see what I get. I'll let you know the results.

From server at 192.168.0.3. It is the DNS for the network. Thus it should also have Forwarders setup in it's DNS config so that anything it can't resolve gets sent out to another 3rd party dns server (i.e. 8.8.8.8 or 4.2.2.1).

From the client, if you can ping something internally, but dns fails when going to an external site, then the Forwarders are probably incorrect.

On a client or even on the server, check dns by opening a command prompt:

NSLOOKUP
server 8.8.8.8
www.google.com
<here you should see a response showing google's ip>
server 192.168.0.3
www.google.com
<here, if you get a timeout, the server is not forwarding dns requests outbound or is blocked going out a tcp/udp 53>

Good NSLOOKUP example. Yes, use NSLOOKUP to test your DNS choices.

OK, now run NSLOOKUP on the client that doesn't work and see if NSLOOKUP works.

This is starting to sound as if the Ubiquity is the issue. I'm not using their product so you may have to call them if this is the cause of the issue. We've done the rest of the checking so what remains is the Ubiquity.

The machine with the ip 192.168.0.3 is the DNS server. Its also the local server/domain controller. 192.168.0.1 is the gateway, which is a netgear firewall. So every machine that has joined this domain is assigned an ip that's on the subnet of 192.168.0.x.

The first set of ip addresses that I showed you was from the server/domain controller. Its ip address is 192.168.0.3. And because its also the DNS server, that's why its DNS is 127.0.0.1. Every other machine on the network is assigned 192.168.0.3 for the DNS.

Does that explain things better?

Here are the ip settings for one of the client:
