I look after an office with a number of Real Estate people in it. Over the last year or so, we have had a number of network issues and they all seem to be similar in issue. The last issue that we had last week was that everyone lost their internet connection and about a half hour after that, the wired workstations regained their connection while the other half the office (wireless side) was still down.
When I got there, I tried to diagnose what the issues are but I couldn't get access to either of the routers. After I power cycled the main router (D-Link DI-615 with wireless turned off) I was able to get access it but of course couldn't find anything wrong with it.
The wireless router (also a DI-615) was still inaccessible. I had to reset the unit and reprogram it.
Both routers and unmanaged switch are on backup power supplies.
We don't know if someone is putting something on the network and thus causing havoc.
We have been trying resolve this issue but don't know what the cause of the problem is.
I thought about installing a managed switch and setting it for only one IP address per port.
I also considered setting all units up to access the main router and that the only way they were getting internet access was to confirm a MAC address with the router. Lots of work since I will have to get everyone's MAC address for their devices.
So is there a better way to do this?
