I will be connecting a 50' Cat5e or Cat6 ethernet cable with a 15' long cable to reach to add an AP. So, to do this, ill need one of these little Cat5 couplers. Im sure it will lower some speed of the data traveling through these cables and the coupler, but how much? That is, if it loses any speed at all? My current internet speed is a wimpy 2Mbps, if that helps. Any help is appreciated. Thanks in advance! PS. I will be connecting my main router to another router in a different room to add an AP.
