Hi I'm new to the forums and I was hoping someone could help.

I have a CNet 4 port adsl router directly connected to 2 PCs. Everything worked perfectly on Thursday last week but does not seem to work now. I went away for the long weekend and when I hooked everything up again yesterday I got an error of "Limited or no connectivity"

The router was completely disconnected from everything so it wasn't shocked by lightning (has happened before). I reconnected everything exactly as it was connected when it worked. I get the same error on both PCs after reinstalling netowrk drivers so I'm sure it is a problem with the router. I have tried four different network cables with the same result. I have reset the router back to factory default settings but still get the same error.

I am running windows xp, service pack 2

Any suggestions would be much appreciated.
 
try running the folowing 2 ipconfigs on each pc. From cmd prompt type:

ipconfig /release <enter>
ipconfig /renew <enter>

Thanks but did not seem to make any difference, same error.

If I try and repair the connection it says it can't renew the IP address. I have tried this with an auto obtain IP and a fixed IP. Even if I try and ping the router, the request times out.

Any other suggestions
 
You cannot ping it, from a machine with no ip address.
Manually set the PC's ip address to be in the same scope as the router's ip address, and then try to ping the router.
e.g. If the router's ip address is 192.168.0.100, then manually set the computers ip address to 192.168.0.101, and then try to ping the router.

If you can ping it, go into it's web site and check the DHCP setting. Its probably off. I don't know why.

If you cannot ping it or need further help, report back here with more info.

The router's default IP is 192.168.1.1. I have tried setting my IP to 192.168.1.2. and pinging but no reply from the router.
 
Some other info I found suggested "powercycling" the PCs and the router so I tried that. Made no difference at all.

Any other suggestions?
 
The router should have a hard reset inverted button somewhere that will reset it to factory settings.
Use a bic pen to reset it.
Reset procedure: Hold the button down wule recycling the power on the router. Give it 5 seconds before relasing the indented reset switch.

I am hoping that the router just got scrambled, which would include scrambling the router's email address.

P.S. Does the routing still work? Can one PC see another PC (with hard coded ip addresses) through the router?

I did try the reset button after trying different network cables. The lights all flick on and off so I assume it was reset but it did not help.

As far as the routing goes, it still works fine. I can connect the two PCs through the router no problem, it seems as if connecting to the router itself is the problem.
 
You need to check whether DHCP is enabled and working on the router. DHCP is the thing that gives out IP addresses.

Other alternative ti to manualy set up ip addresses. Choose IP's which are in the same range as the rouuter e.g. if the router is set to 10.0.0.2, then make your manual IP's 10.0.0.10, 10.0.0.11, etc. Also set the dns and gateway to the ip address of the router.

As I mentioned earlier, the ip address of the router is 192.168.1.1. I have set my ip to 192.168.1.2. and many others in that range but I still can't ping the router or view the login page in my browsers at that address. If I could get to the login page I'm sure I could fix it but I can't even get there. When I check the network connection, my pc is sending plenty of info to the router but getting nothing back.

Man this is frustrating!:mad:
 
Alright. Let's see if I have this straight.

The 2 PCs are connected through the router? And you can ping each from the other?

Yet you can't ping the router itself?

Do the 2 PCs get their IP addresses from the Router or are they applied statically?

To find out right-click on Network Icon on the Desktop, select 'Properties'. Right-click on the Network Icon in the window and select 'Properties' again. Scroll Down to 'Internet Protocol' in the lower pane, click on it an click the 'Properties' button. Is the 'Acquire IP Addresses Automatically' button checked?

Open the 'command prompt'. (Start Button->Run->type 'cmd' and click ok. Sorry if i'm being a little too basic;))

Type 'ping -t 192.168.1.1'. Reboot and reset the Router. Watch the ping. Does the router send back a reply at any stage?

Yet you can't ping the router itself? - Correct

Do the 2 PCs get their IP addresses from the Router or are they applied statically? - When connecting to the net they are automatically assigned IPs by the router.

Type 'ping -t 192.168.1.1'. Reboot and reset the Router. Watch the ping. Does the router send back a reply at any stage?"The request timed out" is the message I get when trying to ping the router
 
Still no luck, looks like I will need to buy a new router:(
 
try using netscan.exe - and checking the entire 192.168.1.0 to 192.168.1.254for devices...

or use "the dude" from microtik.
 
did you put 192.168.1.1 in the default gateway section op die pc's ip config? and in dns server also

I did try that and unfortunately it did not help.
I will try "the dude" and see if that helps.

Sorry, I haven't been able to get back to you.

What are the addresses assigned by the router? In other words, what are the addresses of the 2 PCs?

If you type 'ipconfig' it should give you the address of the PC. Is it on the same subnet?

Something not right here.

Normally the "Limited or no connectivity" error message is because the PCs are unable to access the DHCP server in the router...
