The most common and effective solutions include installing a network switch, using a dedicated Ethernet extender (or repeater), or converting the signal to run over fiber optic cable with media converters. Do I really need gigabit connection between router and switch if switch is the only device connected to router and the speed of internet is under 100M? I mean I can replace the cable, but if it's still gonna run only at 100M even with 100% cable I'd rather not have to remove ~15m of carpets and. To extend an Ethernet cable beyond its standard 100-meter (328-foot) limit, you must use an active powered device to regenerate the data signal. This issue has also been discussed among COBTEL 's engineers before. In our home LAN, the transmission medium is typically 100Mbps network. If two GE interfaces are connected using a 100M network cable (Category-5 or lower category cable), the interface speed cannot be negotiated as 100 Mbit/s and the two interfaces are in Down state.
