how to fix network issues with possible IP conflicts

hi josh

thanks for the advice, i've had a few more problems over the weekend

i tried to reconfigure the network by starting with one router at at time and have got into a worse position. The 48 port switch has come off the network and I cannot access it. ive tried it's IP address 192.169.0.239 and this will not work and also the switch itself by ethernet cable will not allow me access. so no pcs in the building can receive a wired connection by ethernet and the phones router cannot either.

if i can't get onto the switch to see if the DHCP has somehow got DHCP on i cannot make any changes to turn it off which i think may be causing the problem. i've been reluctant to factory default the switch but not sure what else to try... not a great start to monday!

thanks

i managed to get onto the switch and turn the DHCP back to off after it had factory reset. i checked the VLAN settings and there were 3 options there but all unchecked.
so currently there are no VLANS selected and the DHCP is off.

I still havent been able to bring back the wired pcs connections though after getting access to the switch.

not sure what to do from here?

From my experience with cisco equipment it is advised to have all ports on one vlan and then create and assign ports to different ones. Could you create a vlan and assign all ports to it.

If you followed my previous post your netgear should be the only router connected to the switch at the moment with no DHCP server. For test purposes please manually assign a PC with a static IP address using the stack mentioned in the previous post - DNS Addressing - How to Change in Windows 7 - Follow this tutorial but also add an IP address, Subnet mask and Default gateway as listed in my previous post. Once done please test internet connectivity by pinging Google

Code:

ping www.google.com

If the machine receives internet connectivity then please post back and I will walk you through enabling the netgear router as a DHCP server.
