cisco modem/router password issues password isn't invalid but redirects to login page
Posted 20 June 2012 - 02:34 AM
I work for Shaw Cable Systems in BC, Canada. Fate has brought a familiar problem into my own home. I just got shaw services installed and my internet works great when its a wired connection. My default SSID doesn't show on the available networks. I work in TSR support and when i get customers to go to their router settings im always asking them to go to 192.168.0.1 or 5% of the time it may be 192.168.1.1. I personally had to goto 192.168.100.1. Google told me to try that one but how could've i had known to try it? where does one find out what the router settings address is?
When I go there im asked for username and password. it isn't the cisco default cause shaw sets them all to User: cusadmin and Pass: (serial number of equipment). I enter it and i get redirected back to login page. If i enter it wrong then i get redirected and i get an error msg saying its wrong password or username but when i enter it correctly it simply redirects without a error msg. i hold the reset button down for 30 seconds and same issue. I tried on a mac laptop and same issue. I'm current on a win 7 64 bit desktop. I tried with four diff browsers. i updated java. uninstalled and reinstalled IE8.
Whats more is this is a issue i've had with customers at work too, twice in the past and got resolved by rebooting in safemode with networking. I tried that and nothing same issue. I know in my heart that its not the brand new routers fault or my computers but I don't trust browser settings or firewall (which i tried turning off too) or some other thing. I think the key to understanding the issue is behind the fact that the correct password doesnt give an error but simply redirects me to login page.
Cisco DPC3825 modem/router
windows 7 64bit
to reiterate, I pressed the reset button in back of router to reset to factory settings, all the help online I've seen gives that as top solution but I tried it already

Your cable modem is also your DHCP server. So if you run this in command prompt:
The values of Gateway and/or DHCP server should match and that IP address is your cable modem.
I've been out of the cable support business, so I don't know much about newer hardware, but have you tried to connect to the secure page? ie https://192.168.100.1 ... not that I would think it would make a difference but I do know that my cable modem (Motorola) is set for secure login only.

are the two most common addresses among the "internal" reserved ones (as an example I personally use another one in the range 10.0.0.0 –10.255.255.255) and most equipment will default to it:
Then you have a "mask", the most common used is 255.255.255.0.
Given that you already have the correct settings in your OS (and if on the network there is any other piece of equipment that is or acts as DHCP server and you have "dynamic" IP settings) it's just a matter of running such utilities and in a few seconds you will get the address of all pieces of equipment connected to the network. (if you have to scan several address ranges it will take some time).
A good software (freeware) for this is:
If the piece of equipment you are looking for is actuall acting as DHCP server, as Tripredacus said an IPCONFIG /ALL will do.
Back to the actual issue.
If I were you I would try :
It is perfectly possible that the password has been entered incorrectly and does not corresponds to the serial on the box
You should be able to reset it anyway via console:

Try shutting down your PC, Disconnect the NIC cable PC->Router, Unplug the Router, Plug it back in, Reconnect the NIC cable, restart the PC. Rerun (in a CMD prompt, NOT in "Run" box!) "ipconfig /all".
The DHCP Server SHOULD be your Router!
Do you have ANYTHING connect "in between"?
ONLY use PC->Cisco - nothing else...
NO WAY is that correct!
edit - see jaclaz' post - apparently you didn't give all info...

This means that the DHCP is @ Shaw.
And also the gateway:
A strange setting , but possible.
You have something similar to this, right?:
Most probably the thingy has also a secondary address in the mentioned 192.168.0.x or 192.168.1.x range.
Try running netscan with these two ranges, limit the scanned range to (say) 192.168.0.0 to 192.168.1.255.
