Asus + Zadacom default gateway problem
I have the Zadako version of Asus WL-500 gP and Zadacom 3G+ modem connected to it.
I faced a real weird problem yesterday. There was some time that I only had used the modem with my PC only. Now after a while (and actually a firmware upgrade to the modem too) I could not connect to internet with Zadacom connected to Asus anymore.
The weird thing is:
a) the same modem worked OK with PC but not with Asus
b) another operator's SIM worked OK with both the PC and Asus
I spent quite a bit of time to clarify the problem, and finally figured out that the default gateway was missing in the non-working case. After adding the default gateway manually with route add command everything works OK.
Can somebody explain to me why this happens and where the problem might be? Or has anybody faced the same problem and which operator? The problematic operator in my case is DNA Finland.
