I'm new here and need your help.
I have BiPAC 8800NL but having all kinds of issues.
I'm using VDSL but it seems for some reason my connection is dropping and because of that wireless is not stable at all.
Another strange thing is that my ISP from which i get this router/modem upgraded with 2.51.d1 version and i've seen that latest version is 2.32. And it says: Model Name BiPAC 8800NL.
As temporary solution i used another router for wifi connected over "wan" port to avoid using bipac 8800nl wifi which i turned off using button.
It is happening that after dsl connection is down (it happens random) wifi becomes unstable and i can connect to some wifi network - only to open wifi networks but not protected ones. And, biggest issue is that DHCP does not assign ip address and gateway after DSL connection was dropped and i need to set static ip address for my laptop wireless adapter and then it works.
Anyway, it happened now again after turning off wireless and using another router for wifi but this time it just dropped and i need to wait ~10 seconds for connection and everything worked fine again.
Sorry for my English it is not best

I will c/p my log here, if you need anything else please let me know:
(this log is only for latest dsl drop, i've done clear before it)
