Hi
Thanks once again for help me. Your first methode advise dont work on my modem The same error appears.
I´ve followed your web link an i´ve tried the next firmwares:
se515a-ne-v021801_04k_a2a015b-nocfe (Annex A! not for ISDN)
rta770wau-v021801_07c_a0_23e8-nocfe-se515 (Annex A! not for ISDN)
The first one taks my modem very instable. I mean the internet connection goes down to much and i need to restart the modem to much time.
The second one from Dynalink appears more stable evan the wireless.
The modem brand is siemens but in my case the better firmware is from Dynalink. Now i keep with the Dynalinks firmware
Problem solved.
Regards my friend
