Problems for BT Modem Users
There are some known complications when it comes to users with the BT Home Hub & other BT kit.
If you are having trouble detecting your Access Points, and you have BT kit, you should create a DMZ for your CT Access Point and ensure the MTU setting's set to 1500.
You will need to login to the router's portal to adjust this. Follow the BT instructions on their site for more information about the DMZ.
