Hey all, I hope this is the right forum; And I didn't want to go to a whole other site to find an answer unless I have to. I live in a 3 story house (basement, main floor, upstairs) and currently I have Comcast internet come into the basement where it goes through it's modem into my Airport Extreme. then off to a handful of items. I have about 6 homeruns of Cat5e to a point in the basement that I'm using the AE and a small router to feed. Well I'm trying to clean things up and want to improve wi-fi on the main floor where we use it the most. So, I want to move the AE upstairs. I'm looking for the best way to do this. (first, I have some existing wiring I want to use, If i don't use existing I'm putting holes in the wall and floor, which my wife won't look to kindly upon) My first and easiest option is to ; 1. Use existing coax run to main floor room where I want to put AE and also run the modem there. Problem is that i will have to use a barrel connector to connect the coax that comes into the house to the coax run that goes to the office. Is that barrel connector going to cause me trouble? or will it not be a problem? Once I do that I would then take the network run that goes to the office from the basement and use it to connect the basement to the AE and put my new router down there and connect all my other hardware. My other options include trying to fish the coax that comes into the house and feeds the modem currently through the wall to my faceplate in the office where the another Coax currently runs and move the modem to the office. Put the modem in the basement as is, and fish a new Cat5e or 6e up to the office to feed the AE, then take a port off the AE and run it back downstairs to a new switch I recently bought. Problem is as above, fishing a new line from my current outlet box to the basement is hard, it's and exterior wall with insulation and the basement has recently been winterized so lots of spray foam filling all the gaps, or existing holes where wiring was run. So, to sum up. Is putting two barrel connectors in my cable run to my modem going to hurt anything? I would use 1 to connect current run to office to run that comes in from outside, second one would be at the wall faceplate in my office where the current coax run already exists.
