682. Adress for your NetGear router changing randomly?

Netgear router resets to factory defaults randomly on its own always changing address between 10.0.0.1 and 192.168.1.1 plus all passwords and settings.  Sounds like a pure NetGrar router problem -- in this case a NetGear WNR2000v4 N-300. Well, after a lot of searching I finally came across a CONFLICT with the AT&T DSL modem and NetGear and other routers which cause this issue! Had me going crazy! I'd rund for days to weeks and then suddenly one morning the router address flipped to the other address AND reinitialized all factory settings! 

Solution: NOTE: Conflicts exist between DSL 4100 and Netgear WNR2000v4. Netgear does not like using an address for the router equal to 192.168.1.1 – it will eventually say it conflicts – and changes it to 10.0.0.1. The DSL 4100 honors both 192.168.1.1 and 10.0.0.1, however, if power goes out BOTH are likely to reset. If the DSL 4100 goes down it comes back up with 192.168.1.1 ONLY and expects the network to be already set to that address, NOT 10.0.0.1. Hence, it will not connect if it is currently defined as 10.0.0.1. If the router  powers off it might reset to default Netgear configuration which is NOT your SSIP. Instead it will default to NETGEARxx and default password. To resolve this issue the following must be done (Bridge Mode):

1.       If router down, i.e., cannot get to 192.168.1.1 nor 10.0.0.1, then connect laptop to DSL 4100 first (cable)

2.       Configure the DSL 4100 to BRIDGE MODE (Cable PC to DSL 4100)

a.       In a browser, enter 192.168.0.1

b.       Select Advanced, then PPP Location, then select the 3^rd (Bridge) option and let it restart the modem

c.        Now power off the DSL modem and back on

3.       At this point access to router should be available at 192.168.1.1 or 10.0.0.1. Enter one and start the router configurator. Cable the router to the DSL modem and PC to router. You will test WIRED connection first.

4.       Configure the router now:

a.       BASIC…Internet…set “Does your Internet Connection require login?” to YES and then enter your ISP login and the ISP's modem password

b.       APPLY

c.        APPLY a second time

d.       Now goto ADVANCED…SETUP…LAN Setup and make sure IP address is 192.168.1.1. Set if not and OK out

e.        Bring up CMD in Windows 7 and do IPCONFIG/release and IPCONFIG/renew

f.        If the configurator was not started using 192.168.1.1 it needs to be restarted with that address now.

g.       IMPORTANT: If you need a NEW backup of configuration, go to ADVANCED…Backup Settings…Save a copy (goes to Netgear_WNR200v4.cfg in Downloads folder). Always nice to be able to restore a destroyed configuration!

h.       If you need to RESTORE the router configuration (to ensure channne, address, name, etc correct, you can RESTORE the saved file Netgear_WNR2000v4_Bridged.cfg.

5.       Internet should now be working on WIRED connection.

6.       Disconnect from WIRED connection and test WIRELESS. All should be good
