About three days ago my ISP changed our regular Arris modem for a wireless modem, Motorola sbg900 ch. Two technicians came and just hooked it up. The modem/router had been configured at their location. My surprise came when I tried to access it to confirm if all was ok as to my needs. (Previously, I had a router connected to the Arris modem, and two PCs and a PS3 connected to the router; only 2 PCs networked, others just had Internet access). Default user ID and password are admin and motorola and access to the device is through a browser (http://192.168.100.1). I can get to the page requesting user ID and password and that's it.
My connection speed has slowed down quite a bit, although it seems ok for the phones. The tech guys left the ethernet port on the modem connected to the WAN port of my old router. I can not confirm there is no conflict between my old router and the modem's integrated router.
Not knowing how it is configured worries me. Also, there are things I have to set up and can't. Is this a standard procedure for ISPs or is it a strange behavior?
I was happy at first because I had been considering adding wireless to my setup. I could reset the device but any specific values pertinent to the ISP would be lost. Is there anything I can do on my end or should I just go ahead and contact them and see what, if anything, they can do, or are willing to do, on this issue?
Can you still login to your old router? If so, check the WAN IP address. Is it your public IP address (190.92...) or a private IP address? If public it means that they bridged the modem/router to act as a modem only.
If a private IP address is it using the same subnet as the LAN of your old router? If so, that is usually a serious problem and you should change one of them. Also, if private, the default gateway will be the address to use to login to the router part of the modem/router.
Is this a standard procedure for ISPs or is it a strange behavior?
Yes, I can login to my old router, that was one of the first things I did; but not knowing what to do next, i just verified I had access to it. I understand what you are saying and will check this out as soon as I can.
Some ISPs supply the modem and lock them so the behavior is not unheard of. Who is your ISP so I can check for postings at http://www.dslreports.com/forums/all ?
My ISP is cablecolor.hn. I am in Honduras at this time. Unfortunately I am dealing with another problem at the moment and have been unable to continue with this thread's issue. My keyboard has stopped working on Win XP and I have no access to it. I am posting this from Ubuntu with the same keyboard that won't work in Windows. I am dual booting this pc with Windows XP Pro and Ubuntu 14.04 LTS. Trying to fix the keyboard problem first since I can't access my old router from ubuntu.
I have not been able to post information due to a keyboard issue. I was hoping to run ipconfig /all with the pc hooked to the old router and the running it again with the pc hooked directly to the new Modem/router. But my keyboard stopped working on Windows XP when I was about to do so. I can't access the old router from ubuntu and I can't login to Win XP. Should I start a new thread for this new problem? I am a little lost at this moment and don't want to panik and make a stupid thing.
Well, I can access my old router from ubuntu. Must have been a previous router I could not access from ubuntu. And I don't use ifcongig -a because I don't understand the terminology that shows up. So I was hoping I could do that in windows. But no luck with my keyboard problem so far.
This is what I got running ifconfig in ubuntu and while connected to old router:
ipconfig/ifconfig is one of the few areas in which Windows is superior to Linux distros.
With "inet addr:192.168.10.101 Bcast:192.168.10.255 Mask:255.255.255.0" we can tell that the subnet used is 192.168.10.x, but that's about all I can get out of the output.
http://192.168.10.1 is my old router access, window asking for user name and password shows up. And I can login with no problem. So now that we know this what conclusion can you come to?
Considering the information for the two connection situations obtained with netstat -r am I going through my old router and through the modem/router just like if it were a plain modem?
That information came from netstat -r while my pc was connected directly to the modem/router. I have no wireless device, my son does. But the modem/router has a sticker with the SSID and the passkey and my son is able to connect with his phone, tablet and laptop.
LAN setting in my old router:
IP address ............ 192.168.10.1
Subnet mask ........ 255.255.255.0
The Gateway acts as DHCP Server........ Enabled
IP Pool Starting/Ending Address ........... 192.168.10.101 / 192.168.10.199
I blew that one but makes more sense. The manual for the SBG900 indicates that the default gateway is either 192.168.100.1 or 192.168.0.1. Insure to power cycle when switching wired devices connected to the SBG900.
http://198.168.100.1 is the modem/router access, login windows displays asking for User ID and password. But these were set by the ISP so I can't do anything else with this device.
IP access:
IP address for old router is 192.168.10.1
IP address for modem/router is 192.168.100.1
I have decided not to continue any further with this issue. I think that my wired part of the set-up is as safe as it can be and will try to add a wireless router in the future that has nothing to do with my ISP, for my son's devices.
Thanks to all who help me with this issue. I couldn't have come to this decision without your help.
