I rent out a house to 6 tenants and provide them internet as part of their service. They have recently had trouble accessing secure HTTP sites like Paypal and Online Banking sites.
The sites they can and can't access are different for each person and their laptop.
I have spoken to my broadband provider and they cannot see anything wrong with the service. I took my laptop around and experienced the same issue where I couldn't get onto the secure Paypal website.
I am at my wits end with this problem! I have been trying to fix it for the past 3 weeks. Tomorrow I am going to swap out the router but I seriously doubt that this is the problem.
Any ideas of what the problem could be?
Many thanks in advance!
