Can't connect to Router using Ethernet

[wilbyforce]

Hi. I'm sure I've been able to do this previously so I'm wondering if the Sagecom router has developed a fault.

I've been using my Sky router as a switch (I used to be with Sky BB but now with another provider) by turning of dynamic IP addressing. I'm fairly sure I used 192.168.0.1 to achieve this.

Now I want to turn off the wireless part of it but 192.168.0.1 doesn't work. I've tried two different computers with two different Ethernet cables and get identical results. I've tried pressing the reset switch.

It was working fine as a switch prior to the reset but I don't understand why the standard IP address doesn't work so that I can change the settings.

Anyone got any clues please?

Many thanks.

If you connected the Sagem to your existing router to use as a switch you must have changed its IP address to one in the range of your main router. Even if you left it the same, which under some circumstances you could, by turning off the DHCP server it means you will have to give your PC a fixed address in the 192.168.0.xxx range as it will not get one from the router.

If you use the reset button, you must hold the button in for about 10 seconds until the router lights flash and it reboots. This will return it to 192.168.0.1 with the DHCP server enabled. You may have to reboot your PC to reconnect to it.

Unless you changed them the username and password are admin and sky, respectively.

Many thanks indeed for that very useful reply. Rebooting the PC seems to have done the trick, I get replies using ping now.

I have it working with my BT home hub now but I've not changed the IP address. If I do change it (to 192.168.1.250 for example) I can't ping it (I get a reply from 192.168.1.77 saying host unreachable ??? ).

Having said that, with the IP address left at 192.168.0.1 I'm still getting dynamic address from my BT home hub via the Sky router, which is at odds with your reply. As long as it works I'm not bothered but I am curious as to why it's working, as you say, they both should be on the same sub-net in theory.

I should add that I have turned off the Sky router's wireless and all of my devices are connected to it via Ethernet.

Thanks again.

I did an Ethernet course some years ago and not used the knowledge I gained so have forgotten most of it, but having consulted my notes I think I have the answer. The Sky router is clever enough to know that it is being used as a switch when it is connected to the BT device ... and of course switches don't use IP addresses, hence its transparency when so connected.

Would you agree with that conclusion?

I can't agree with the Sky router being 'smart', but it may be the other way round. The BT Hub may be smart enough to treat it as a switch. This is the first time I have heard of a Sky router connecting to another router without having its address put in the same range as the other router. Maybe someone else could comment on what is actually happening.
