The LAN on Router A is a 192.168.1.0/24 bit address and the only way to
reach it from Router B is either by a static route or EIGRP.
Your EIGRP network will not advertise this judging from your current config.
Try adding the Network statement for 192.168.1.0 on router A. Also if you
have omited this because you don't want EIGRP to advertise routes over the
Ethernet port use the passive interface FA0 within your router EIGRP portion
of the config.
