I know this is highly unlikely to be possible but is there any way to boost wifi coverage of a wireless router with the use of wired computers that also have wifi. We live in a three story townhouse. Our wifi router is right next to the primary phoneline at the front door so as to get maximum adsl connection speeds. However, luckily the previous owner of the house decided to wire up the whole house with wired ethernet (much to my glee when we moved in and I spotted all the network points). I've currently got three wired macs in the house, one on the bottom floor in my office (mac pro), one on the first floor in the lounge (Mac Mini) and one in the attic (iMac for server use). The Mac Mini and the iMac are on 100% of the time and the Mac Pro is on probably 95% of the time. Is there any way to use the wifi on all these three machines to boost the coverage of my existing wireless network? Our laptops and iPhones don't get particularly good reception on the top floor at the moment.
