in my house, we have a shared network. Recently Ziggo had sent us a new wifi hotspot device as the old one had issues with coverage..the problem is since then my iphone and macbook cannot be used for specific websites like twitter, ziggo, espn, twitter...
On the other hand some sites like facebook, youtube, google are working fine..
sometimes when i jump between the 5G and non-5G couple of times, all sites begin to work but then after a few hour the problem comes back..
Only i have apple devices in the house..other people with windows and android devices do not face any problem..
Also to be noted that i cannot access the device IP address from my browser and hence cannot check if there is proxy or firewall related issue..
