I currently have been using a WRT54G router to interface with my network at university. It is set up to be used by my desktop PC (hardwire), laptop (WiFi), and Xbox 360. However, I keep having issues with random disconnects. I have replaced and checked every cable within my system and my network administrators seem to have no clue on what the issue is. I strongly believe that it has nothing to do with my setup and is more related to the wiring of the dormitory. Main reason why I say this is that when I first moved in, I had the same issue without the router. Upon doing some measurements, I found that the impedance between the access port and switch port was 27 ohms. This is extremely higher then the 4 ohms that its supposed to be. Cleaning and adjusting things, the impedance was lowered to 4.6 ohms. Now... I have been told from my network administrator that the issue is with my setup and that I will need to provide proof otherwise. I am trying to figure out if the router can be the issue or not. In order to get the connection back after a drop, I have to reset the router or unplug it from my access port.
