1.) Telnet to your speedtouch, 192.168.1.254 (or wherever it lives) and login with your normal username and password.
2.) Type ip.
3.) Type arplist, this should print out your routers current arp table which should contain an entry for your machine.You need to delete this dynamic entry and add a static one so you need to take a note of the Interface, IP-Address and Mac-Address of your machine.
4.) Type arpdelete, enter "LocalNetwork" for intf, your machine's ip for ip and your machine's mac address for [hwaddr].
5.) Type arpadd and enter the same parameters above. If you get the following error:
Failed to add ARP entry....
This is because the router or machine arp broadcast within the time of removing the dynamic entry and attempting to add the static entry.
Re-run the delete and then add commands but in very quick succession. EG:
{Administrator}[ip]=>:ip arpdelete intf=LocalNetwork ip=10.0.0.108
{Administrator}[ip]=>:ip arpadd intf=LocalNetwork ip=10.0.0.108 hwaddr=00:24:e8:25:72:f3
Alternatively, turn the target computer off and telnet to the router from a different machine. This will ensure the it's possible to delete the target computer's entry from the arplist. It's even possible to use Mocha Telnet Lite from an iphone or ipad.
6.) Type arplist again, your machine should be back in the table but the entry in the type column should now read static instead of dynamic. |
