Microcell doesn't work with Netgear N450 router
I have a Netgear N450 router to work with comcast internet.
I have tread the suggestions for adding a Netgear router (nothing specific to N450) and the microcell drops calls after about 5 secs.
I have set
DHCP Reservation Lease Info
#Mac Address IP Address
MTU size to 1492
I have forwarded ports 123, 4500, 500 & 443 to the MCell ip address.
I have reset the Mcell and all the lights are green.
Microcell starts the call on my iphone, but drops after about 5 sec.
What else can I do?
