Wan is 200 mb, 3 lan cards one is not going above 1 meg

[hadi57]

hi

i have:
wan 200 Mbs configured as dhcp client runing as hot spot
lan 192.168.100.1 configured as dhcp server runing as hot-spot
opt1 192.168.150.1 configured as dhcp server  connected to 3 isa servers, each server configured to a static ip 192.168.150.45, 46 & 47
opt 2 10.10.0.1configured as dhcp server runing as hot-spot

the issue is the 3 isa servers each one is taking 1 Mbs only
other lan and opt2 no issues

turning traffic shaper on and off didn't make any difference

can any one help me solve the issue why each isa server is not going above 1 Mbs

ttanks in advance for the help
