Switching from old provider to new

[AlexanderCS]

There's a business in my area that wants to switch from cable to DSL. They'll be saving money on their phone bill enough that makes this worth it to them.

The setup is:

-RCA Cable Modem
-Dlink DIR-655
-Dlink DGS-1016D Unmanaged Switch
-Synology DS213+ NAS (the employees connect to this to access files)

The new network equipment is a modem/router combo, a Bell FAST4350.

I was under the impression that I would eliminate the D-link router and RCA modem. I figured it would go DSL line into the Bell unit (under DSL of course) and then I'd simply take the cable from the switch and disconnect it from the LAN port on the old router, then plug it into a LAN port on the new Bell router. I then unplugged the switch and plugged it back in.

The network did not enjoy this. Although I was able to get the desktop machines onto the internet, the printers were not seen by any of the computers. The NAS unit was also completely unavailable.

In the end we flipped back to the old provider, since the service hasn't even been cancelled yet (and they didn't plan on cancelling it until Bell was in there and working anyhow). This is why I'm taking steps to understand networking and servers--if I want growth, it has to happen.

What's the best way of going about this change? As always, I appreciate any advice.

Since you didn't say, are we to assume that you changed the LAN settings of the speedy Bell FAST4350 to match how the Dlink DIR-655 was configured?

Along the lines of what altrenda said. Did you make a network map, complete with IP information for each device. Lacking many details but off the top of my head, with printers and NAS offline, it sounds like the computers may have been DHCP (which is typical) and the printers and NAS may be fixed (which is typical in a business).

I have got to agree with the above, double check the lan IPs I have seen this a few times, the default IP address on ten new router is most likely different than the old one and the rest of the network can't see it

Typically the ISP provided "gateways"...(modem/router combo) can be configured to a bridged mode, where they'll pass the public IP address to the WAN port of your own router. This means you should easily be able to "transplant" the existing network to a new type of WAN connection without changing the network much. Hopefully their network was not the common 192.168.0.xxx or 192.168.1.xxx setup...as many phone company ISP provided gateways have this native to their gateways LAN side.

Hey folks, just a little update on this.

After taking the advice in this thread and mapping things out, then doing a bit of research, I was able to get things going. Despite a small snag where it wouldn't go into bridged mode (and there's no option in the GUI for this on the Home Hub models), a brief call to get them to do it remotely (which will apparently allow me to set it manually in the future) has it all running. I entered the PPPoE info into the current router and that was that.

Thanks everyone for pushing me in the right direction. It's always a big help.
