Hi my router seems to work fine for about 3/4 weeks it then suddenly stopped connecting to our broadband. 

No ip address

No default gateway

No primary DNS

No secondary DNS

My old router connects perfectly fine every time.

I have reset it several times but with no luck.

I also contacted my ISP provider and the line to my house is fine (old router connects)

This happened a few weeks ago and somehow I got it working and it worked fine.

Thanks.
