I recently tried moving my modem from the ground level to the second floor, where I just put in a PC in my office. I have 3 phone jacks upstairs (2 in the guest room and 1 in my bedroom), but it would be much more convenient to run an ethernet cable to the PC if the modem were in the guest room.
Unfortunately, neither of the phone jacks in the guest room work. One blinks green on the DSL light, but the internet light never comes on. The other jack gives the DSL light a solid red.
For whatever reason, the phone jack in my room works just fine (DSL light turns solid green, internet light comes on). I've done some preliminary Googling but haven't been able to come up with a solution, even though I've seen similar posts. I have no phone filters (no landline to hook up), and no splitters.
Any insight would be much appreciated!
