False - a repeater is a simple layer 1 device. It would not have a need to operate at the network layer.
Network layer
A repeater. Repeaters work only on layer 1 (Physical) of the OSI model.
Physical layer = Hub, NIC, Repeater. Data Link Layer = Switch, Bridge. Network Layer = Router.
G repeater will not work with N network, unless your router is configured to work in compatibility mode. It means that your router can work with both G and N networks. Thus when you connect your G repeater it will extend only your G network.
An active hub can act as a repeater hub. It may also work as an Ethernet hub, network hub, and a multiport repeater.
It is work at Network layer.
Physical layer devices would be a hub or a repeater to connect multiple Ethernet segments together.
A network bridge joins two networks to make one. A network repeater extends one network to make it larger/more powerful.
There is a good descrition of the network layer and TCP in the related link. NO. In general TCP and UDP are transport protocols that operates in Layer 4 Transport Layer
Repeater.
