Eircom Netopia 2247 connection problems

markjbloggs

Hi,

had a major problem with my PC, possibly some corruption in the boot files. After restoring it to something like working order, I cannot now connect to the internet. No hardware changes were made.

The router seems to be working correctly (all 5 lights are on as they were before the problems). I can ping the IP address of the NIC card properly - should I be able to ping the default gateway (192.168.1.254)? DHCP is enabled

Any help would be appreciated

What's the IP of the NIC? Did you set it manually, or is it applied by DHCP? You should be able to ping the router if it's connected and detected properly.

I set it manually after I had the computer problems - I do not have a record of what it was before that. Irealise now that the NIC is not set up correctly.

If you do not have an internet connection, does DHCP work?

How can I find out what is the correct IP address for the NIC?

Ironbar

Press Windows+R

type cmd -> Enter

type ipconfig /all -> Enter

you see all your network adapters, IP adresses and details e.g. if DHCP is activated.

the ip adress of your network adapter should be ideally identical to the router on the first three numbers.

Example: Router ip adress: 192.168.1.254 , NIC adress 192.168.1.XXX

you can adjust this in your network settings in the control panel.

router settings for the netopia you can adjust by opening internet explorer and type "http://192.168.1.254" (Enter) into the adress bar. the last number might be different now.used to have eircom 5 years ago.

You look like you are connected to the modem anyway which is a good start.

Did typing 192.168.1.254 into the address bar of the browser load the modem page?

Try to ping google.ie. If that doesnt work ping the IP (66.102.9.147).
If that does work you need to flush DNS.

ipconfig /flushdns <enter>

Try to load a page.

If the above doesnt sort it then back in cmd prompt type:
netsh <enter>
int ip reset reset.txt <enter>
dump <enter>
You need to restart then and try a page then.

Dump gave a lot of scrolling text but int ip reste.txt gave an error - command was not found.


Still offline :mad:

Type:
netsh
int ip reset reset.txt

You need to restart after this.
Its basically just resetting the TCP/IP settings in your PC.

Can you ping the modem?
ping 192.168.1.254

Have you a firewall or anti virus software that might be blocking you?

Have you another PC connected to the modem which is working?Just to rule that out.

Cannot ping 192.168.1.2 but not 192.168.1.254

No firewall or virus running.

No other PC available right now.

Unplugging the cable to the modem results in a "Local Area Connection 4 disconnected error". Powering the modem down does the same thing - so am I correct in saying the PC is "seeing" the modem but is not communicating with it?

Folks,

any thoughts on this? Eircom have been no help, though it does seem that this is a PC problem.

Are there any good PC "doctors" in the south Dublin area that can do house calls? If so, how much do they cost?

thank you in advance,
