Are you plugged directly into one of the 8120 ports? Pressing the reset button, will only reset the inital user and password. Maybe you want to look at the manual for some ideas?

My screwed up my lan ip settings on my 8120 and it became impossible to access via. However, there *is* a console port.
Just remove the rubber rectangular plug next to the power switch to reveal a 4 pin connector. Order a A232DBH (Max232) *3.3 volt version!!!* (see end of message for ordering details)
Pins facing the back, from left to right:
______|----|______
| O O O O | (connect from 8120 to
-------------------
RX TX GND VCC+ (pin on Max232 board)
Open up a terminal program set to 9600 baud, fire up the router and login (admin / admin by default)...
Except for trying to identify the pins, this is a very easy project. There are only 4 wires to solder. I used a CD rom audio cable for the 4 pin connector on the 8120.

Telnet into the router. Type help. You can restore it from there. No need to reset it. If worse comes to worse you can unplug it. Leave it unplugged for a few mins. |

NOTE: this is in response to the post by giannuzzelli
yes, but all of that assumes that you knew the ip or had a valid subnet. If the values aren't right, the router resets them to 0's and presto...no router intreface. |

Caro amigo Horácio, leia o documento anexo, descrevo o circuito para o
cabo console do 8120, e funcionou 100%, mesmo sem o MAX 232, pois estava sem
no momento, então providenciei um outro circuito facilimo de ser montado.
Verifique tambem, informações sobre o 8120 e o RTA300 serem identicos.
Quando tiver mais documentação te envio. Abraços. Papi
Particularmente, utilizei o circuito abaixo, por não ter em mãos o MAX 232 e funcionou 100% a utilização do console no Briteport 8120, ou RTA 300
Outra informação que obtive: Tem pessoas, usando o firmware do RTA300 (do concorrente), no 8120. Acho que o 8120 é clone do RTA300, sendo que o RTA300 possui muito mais recursos de configuração em seu firmware. Veja abaixo:
Por essas e por outras, a conclusão, e ser clone do RTA300 veja figura abaixo:
Pela parte traseira, observam-se a mesma disposição das portas ethernet, console, alimentação e reset, exceto pelo modelo dynalink ser USB também, e sendo suprimida uma das conecções de telefone no RTA300.
Verificando o manual do RTA300, observa-se que os menus de configuração são idênticos, apenas em disposições diferentes, e até com mais funções.
Analisando também os firmwares decodificados, observa-se compatibilidade quase que total.
Outra prova, é em relação aos modelos: 8120 = RTA300 e 8420 = RTA300W wirelles.
Horacio, apenas acrescentando, nas informações enviadas, os seguintes dados:
Ao acessar (ligar) o modem com a console ativa (hiperterminal aberto), aparecem as informações do BootROM.
No caso do Broadxent, aparecem informações com o nome de Askey ou seja, o Broadxent possui o BootROM da Askey Computers (Dynalink) .

Lá tem todas as instruções para se fazer a gravação ISP.
O problema é montar o gravador e fazer o software de gravação sem
experiência em eletrônica e em programação.
