At the house my roommates and I down at college are renting, WiFi just hasn't been working out lately. Something in the vicinity is causing massive interference (was working for the past year just fine though). Tried changing channels, even tried a different router, and nothing works. Wireless will just drop out every now and then, sometimes for 30 minutes at a time. We've given up hope and I just ordered a 100 foot ethernet cable and an 8 port switch (to serve my room and the room next to me) from NewEgg. Now, we need to run the cable across a hallway and kitchen to get to the switch which will be my room. Obviously, we don't want it on the floor, so we need to hang it from the ceiling. We don't want anything that will ruin the paint or drywall, since we'll be out of here in a year and anything we damage, we have to pay for. We're not looking for cosmetics here, we have no problem with an ugly ethernet cable running across the house, we just want it out of the way. Does anyone know of something I can buy to hang the cable that won't damage anything and isn't permanent? Thanks
