Coupler Lan

does using coupler in LAN wiring affect the speed of internet?

coupler is the one that acts as a connector of two separate lan wire and has a two opposing port that fits RJ-45 connectors

Potentially. When you split a network cable connection like that you risk introducing noise into the line which could adversely affect the data transfer speed of the line. Also, depending on the quality of the coupler, the coupler itself could severely reduce the transfer speed of the line. Cheap couplers do not have any shielding and could use low-quality wire and pins; whereas high quality couplers may have have any effect on the speed. So, it is very possible that the coupler could be affecting your internet speed, but it may not be the case. Try using a solid single Cat5e cable and see if that helps things at all. Don't forget that Cat5e has a max signal integrity length of about 100m (~300 feet). Don't use a cable above that length.
