want delete Windows network /home

[Eglefino]

Hi,

I visited multi fora with this question, but did not find any solution.

I had for years a Windows computer (31-years), but trying Ubuntu I had a dual setting with Windows 7 and the live cd and with Lucid the internet-setting were used for the installation of Lucid. I tell you short this story backwarts so with the installation of Precise the same setting were/are in use, together with my own Netgear WNDR3700v2 router.
Now I got from my provider a new Ubee modem/router and his settings are 192.168.178.xx and the home-network which I have in use (a Windows-network) have 10.0.0.2.
I have also tried before when I used Lucid (with my Windows experience) to delete that Windows-network and install a home-network p.e. from the live-cd or as package, p.e. gnome networks-manager.
Now I have problems with the transparant firewall ufw because of the new and the old settings (ports) and problems with the automatic update-manager (not Synaptic) because it crash half way, I have post my message even in Launchpad (~ruudino-k) because I have more problems with Precice (maybe all together is a chain-reaction) Lucid was better, but we going in the future.....

In theorie it's possible to install two home-networks in one platform as Ubuntu even in Windows, but I don't want to go backkkkkk.
The profider-guy who installed my modem/router had even problems with my computer to install the new settings under DHCP, because the old settings did not disepear! So I said I try it myself as newbie but nothing is going...., I bought a Synology NAS and all install settings which I had to follow with the manual (because it was not in the list) but I got a direct connection, no problems with that modem/router. Not all that settings are ready, so I delete there all. I'm bedridden so my PC-work out of my bed I will it do it all together when my body have energy enough; I have a disabled friend who helped me with all installations, he is a specialist with Ubuntu, but asking him this isn't his routine. Even I'm new I want to learn it from the terminal.

I can't image that the above code is such a mesh, there a lot of errors and less protocols... I see nothing.... I think it's not possible to write a ufw log myself, this is terrible.... Oh by the way, iI'm Dutch and English isn't my language there could be some faults . I even can to delete all and install Ubuntu a new time (there are now 4x 12.04 on my PC, in all are documents)

Hope someone can help me, or give me a (?step-by-step) way to a solution in the terminal

With thanks,
Ruudino Amsterdam, Netherlands

What I'm guessing is actually fairly simple, but first an quick overview of what I think happened: your original access was via an access point like a cable modem connected to your router. The original access point (the cable modem) was also a router. This results in the 192.xxx.xxx.xxx addresses being assigned to the cable modem's router, and since your router was plugged into that, your router now assumed the addresses of 10.xxx.xxx.xxx. I would also suspect that your new configuration as the cable modem and wireless router all in one, with no need for your original router. That means your network access is now via the 192.168.xxx.xxx range. If you already have a connection "defined" for your old network configuration you need to delete it. Click on the network manager icon on the top bar and edit connections. If your old network is listed just delete it. Now hopefully network manager will find the your "new" network and it will prompt you for the security key. I hope that's what it was, and I hope it's as simple as deleting the old network saved definition in network manager, then just connecting to the new net. If I'm way off or that doesn't work, just post back and I'm sure someone with much more knowledge than me will help you.
