This is advice for new users.
This is the set up with the least problems.
Dumb trainer
Power source
Connect with Ant + with USB extension
Desktop PC running Windows 10
HDMI cable to a TV of choice.
After almost 5 years, I would say most issues people have tend to be related to their set up and the majority of issues are:
1.Speed sensor issues
2. Smart trainer issues
3. Bluetooth issue
4. Apple products
5. Laptop problems.
Many people Zwift with all set ups everyday but there seems to be a pattern to the forum complaints.
