Open an Elevated Command Prompt  http://www.eightforu...indows-8-a.html

 

Type with an Enter after the line:

nslookup geekstogo.com

Do you get something like:

 


C:\Windows\system32>nslookup geekstogo.com
Server:  cdns01.comcast.net
Address:  2001:558:feed::1
 
Non-authoritative answer:
Name:    geekstogo.com
Addresses:  104.28.28.94
          104.28.29.94

 

 

Or does it time out?
 
Try:
 
ping  192.168.1.1

This should give you something like this:

 
C:\Windows\system32>ping 192.168.1.1

Approximate round trip times in milli-seconds:
    Minimum = 3ms, Maximum = 3ms, Average = 3ms

 

 

 

 

Now try:

tracert  -d  8.8.8.8

Do you get trace complete at the end or does it give you 29 lines of stars after the first line?

Disconnect the power from the modem.  Disconnect the LAN4 cable to the PC.  Disconnect the power to the router.

 

Plug in the modem.

 

Connect up the LAN4 to the PC.

 

Once the lights settle down try the nslookup or tracert command again and see if you get anything different.

It appears your modem is not working.  Call your ISP.  They can do a loopback test and also check the status

Erm, well, where I live, let's just say the ISP technicians are completely textbook-oriented, i.e. they don't seem to be capable of critical thinking, in that if it's 'not in the book', it cannot be solved. I say this confidently due to past many experiences, where all of which I had to sort the issues by myself, ever since dial-up days. 

 

If any, I called them up yesterday, they were supposed to come today, and this was what I received this morning (it's night time here now):

 

Dear Valued Customer, there may be some delay in restoring your service. We apologise and will update you accordingly. TQ.

 

and 2 hours prior:

 

Dear Sir/Madam, restoration works for your service is in progress. TQ

 

 

I could bring up asking them to perform the loopback test & status check, but I don't see much hope. What can I do meanwhile?

Sounds like they are aware that they have a problem.  If it's on their end there is not much you can do.  

 

I suppose you could log in to the modem and see if it tells you anything.  Often there is a password on the modem's label.  If not Google the make and model number of the modem  and get the default password and see if you can get in that way.  To logon just open a browser and put in 192.168.1.1 and hit Enter.

Ah, you really trust them.

Sorry, anyway, for mine is 192.168.0.1 and no I cannot log into it:

BUT I can log into that wirelessly:

Also, does this mean anything, can this help with the troubleshooting?:

Your router may be 192.168.0.1 but the modem which you tell me you are directly connected to is 192.168.1.1

 

 Default Gateway . . . . . . . . . : 192.168.1.1

I found the root cause, and it's very silly! 
What happened was that the LAN/Ethernet cable was connected to the modem, not the router. 
 
When called the ISP customer service:
  • 1st Representative (8th June): Asked to connect the phone line to the TEL1 port, disregarding the DSL port
  • 2nd Representative (8th June): Asked to connect the LAN/Ethernet cable from modem to computer*
  • 3rd Representative (today, 10th June): Said connecting to modem is incorrect, should be connected to the router -> connect to router -> issue resolved
*Point after when I started this thread
 
Thanks for the help RKinner, this thread can be closed.
