I have a MacMini, running on OS X Lion, set up as a server.
I struggle to understand the server set up, and had an IT guy set up the configuration for me.
It worked fine for about 18 months, but recently all my devices/client computers have had intermittent problems connecting to the Internet.
Maybe once a week or so, for several hours.
The server is set up to be the DHCP issuer and DHCP is disabled on the router.
The Router has various port forwarding set up.
The server has a wired Ethernet connection to the router.
When the client computers (MBPs, ipads, iphones) lose their Internet connections, they can still see the wireless network, but are unable to join.
The mac mini server usually is still able to access the Internet - and able to connect to the router admin panel.
The router confirms its connected to the Internet.
Rebooting the router and/or server still doesn't allow the client computers to connect to the wireless network.
Can I assume, from this, that it's an issue with DHCP?
I have server admin tools installed, and when this issue arises, there's a green light next to DHCP in the settings.
To be honest, I don't use the mac mini as a server - as the main reason for it initially was remote access to files, etc, but I now use cloud storage.
I have a static ip address from my ISP (again, to access files remotely).
I do have a hosted website, and the email addresses for that are directed to and picked up by the server exclusively, so I'm guessing that if I stopped using the mac mini as a server, I'd lose those mails, but they're more historical, and I keep them for the odd stray message that comes through.
Bizarrely, the connections will just come back randomly on their own, but usually after several hours, of their own accord.
95% of the time, the network runs fine, but for that 5% of the time, it's frustrating as I also work from home, so it's a pain.
Can anyone advise how to resolve this? Or at least she'd some light on why it might be happening?
As the router isn't the DHCP issuer, wiring the client computers directly into it still don't allow them to connect to the network.
I'm tempted to disable DHCP on the server and enable on the router, but too scared, in case I can't connect at all due to a wrong setting - and I'm sure it's more involved than simply clicking "disable" in server tools (file sharing, etc?).
I wish I'd never had it set up this way, as I feel that if the router was the DHCP issuer, it would all run fine,
As a side note, I moved house in July and this has all started since then, despite not changing any settings at all.
It's the randomness of it that frustrates me, and how it will just connect again hours later, of it's own accord.
Sorry for rambling and the lack of technical info/knowledge.
Can anyone help? Please.
