Goodnight.
I have little time working as an assistant IT administrator in a company.
And I have been having problems with the client PCs, they lose the dhcp IP constantly and when i'm changing them to static, they still do not have Internet access sometimes because there is IP conflict, after a few days i change them.
Then a few weeks ago it started now to assign IP from another network (vlan 192.168.0.1-254): which is the one that works as backup internet output, when the fiber optic output fails; when the connection is lost again via IP. and in that network there is nothing assigned, so it is to have to go to change the ip to the network where there are printers, copiers and servers (vlan 192.168.1.1-254)
I have no idea why is happening this.
Could you help me to see how I could determine the fault in order to correct it?
And taking advantage of the post I also have the network currently exposed, slowing activities and also vulnerable to attacks and viruses.
The structure is currently like this:
1-fiber optic internet provider and copper cable internet provider
2-router vigor 3900
3- gigabite vigor manageable switch (I don't have the model at hand)
4- N number of gigabit and 10/100 non-administrable switches (tp-link brand mostly)
5- unmanageable wifi antennas operating as hotspot (tp-link too)
6- network of surveillance cameras interconnected by antennas with each other and the vigor switch (# 3)
(If u need model and brand of the hardware i can post it later)
I have read in this forum some ideas about how the composite network should be, but it is not very clear yet to me.
