Well the IPs from the Yellow pool don't work for me :/
I'm on 2MB (yellow) package. The router is TP-LINK WR-720N.
Whenever I put any one of the alternate IPs from the yellow pool, the router acquires the 'IP address', 'Subnet Mask', 'Default Gateway' and 'DNS'. But it fails to acquire the 'Internet IP Address' and 'Internet DNS'. It just keeps 'connecting' but to no avail. It works fine on yellow2.connect.net.pk. Don't know what's wrong.
