Trying to run a second line into my bedroom working from Brighhouse router, anyway to do it without ahving to buy another router or spend lots of money getting cable company to run a new line, not secure with using a wi-fi connection because of what I work on at times. Does the router have the typical 4 ports on back? What make and model is the router? I don't believe Brighhouse is a router brand name. Did you MEAN that Bright HOUSE Networks is your ISP (Internet Service Provider)? Maybe the O/P actually means a Bright House "modem" ? truenorthYes, that could be so; perhaps she actually has no router. Also, I believe some ISPs provide a combination modem/router, which, like a separate router, would most likely have 4 ports on back to support multiple computers. Hopefully time will tell us. truenorthBrighthouse is a cable company.

It sounds like you will need to run another line to your bedroom some how.

You don't need another router.I ran an ethernet cable from one floor to another by going mostly through cold air furnace intake channels inside walls. In this case, the cable was basically going from router in a ROOM on a second level to a room directly below on the first level. I merely drilled one or two holes in framing studs in the wall to achieve this; I did not need to cut holes in any any wall. The cable COMES out in the RECEIVING room right through the cold air vent on the wall. It's a bit unsightly but it's not a permanent situation; I can easily remove the cable with no visible trace left of it ever being run through the wall.

I don't want to try to explain this in more detail. Suffice to say you may be able to run a line with less structural invasiveness than you are thinking now. You may just need to carefully analyze the situation.
