Get password from a Modem

We have installed in our network a CPE device, it´s a LigoWave DLB 5-15 (access similar to a router) that we configured 5 days ago, the good thing is that we have remote access to the web login page via network, the bad thing is that 1 of 2 things hapened: we put on a wrong password to log in so now we can´t access, or we leave it in default and someone took advantage and write his own login credentials. This is from our own local network (we can prove it) but it´s remote and we don´t want to go there again just to reset the equipment so we are looking for someone that can get in (Brute Force, Dictionary, etc, don´t know) to set the correct passsword for this device. TeamViewer would be given to let you work.
