I have a Huawei 8546m router. I recenty reset my router for some reason but when I tried to login to my router, I couldn't cos my default gateway ip was missing. I tried everything I could find on the internet but I still couldn't get it to work until someone from the isp came to my home and magically did it for me(the ip changed from what it was before though). Can someone tell me how he did that cos they won't tell me.
