Hi all! I have a simple(?) problem with my old router. I had this for 2 years but I never used it till today. So its brand new, just without warranty

. Long story short, this router can't connect to internet. I tried resetting the router, newest firmware, stock firmware, chaining the Ethernet wire, etc. Nothing would work. The weird thing is, I can connect to the router both wirelessly and through the Ethernet port, but the router can't "communicate" with my Netgear cg3000d. I used the wizard to set it up. Please help!
