Last night my WNR3500L suddenly lost the internet connection for the first time in the three month I have had it.
And now it turns out that it is having difficulty obtaining an IP address using DHCP, but when I try to connect my computer directly without the router there is no problem with DHCP and the connection works, so I figure it must be something with the router.
I have tried to upgrade the firmware and later to install DD-WRT, but the result is the same. It take forever to get an IP address, and when it does is it the something like 192.168.0.102 instead of 192.168.2.10 when I connect the computer directly.
We have a shared broadband connection in my building with a large switch in the basement, so I only have a ethernet plug in the wall, no modem or anything.
Could there be a problem with the routers DHCP? Everything else seems to work.
Any ideas about how to Troubleshoot this further are much welcome.
