Question about Speedstream 5100 modem and router combo |
|
|
| When the modem is properly connected (five green lights) I can access it's setup (192.168.0.1) with the router (192.168.1.1, DHCP enabled) in the circuit. However, when there's a problem with the connection, such as the internet light being off, I cannot get into the modem config through the router. I have to plug the computer Ethernet wire directly into the modem. Any idea why that would be the case and if there's a workaround so I don't have to mess with the wiring? |

If I understand sub-netting right and assuming your subnet mask is
255.255.255.0 then your router and modem are in different subnets
(192.168.0.x vs 192.168.1.x). It seems to me that both the router and
modem would have to be in the same subnet to work properly (ie they both
have to have addresses beginning with 192.168.0 or 192.168.1. |

Thanks for the reply. I tried changing the IP addresses
along the lines you suggested, i.e. since the DSL modem is
set to 192.168.0.1 I set the router to 192.168.0.2, but this
didn't work at all. I could not connect to either the modem
setup or the router setup, nor could I get out to the
internet. Changing the router back to 192.168.1.1 enabled
everything again. The only problem though is the original
one, i.e when the modem is having a connection problem I
cannot get into it's setup screens through the router. I
have to disconnect the router and plug directly into the
modem. Any additional thoughts? |

With the normal 5100b config it should connect PPPoE automatically and
give your router a DHCP IP on its WAN. However, default DHCP lease time
for ethernet side of 5100b is a rather short 10 minutes, which you may
want to lengthen if connected to a router. I do not know what the default
idle disconnect time is for PPPoE, but you may want to check that too.
If you are trying to figure out what is going on with PPPoE, you can set
the 5100b to let the computer do PPPoE (computer in this case would be
your router). Then configure your router to do PPPoE (using full e-mail
address for login name if SBC). Your router logs should tell what is
happening with PPPoE connection, but you may not be able to access modem
at all unless you reset it (I think reset hole is hidden by label on
bottom). |
