we've got a new network at home. The structure starts with the actual router which is connected to a Sonicwall TZ180 hardware firewall which is again wirelessly connected to two access points / repeater over which I go online.
1.) When connected to one of the access points I can go online and surf the internet. However, there's no upload at all. I can't send any emails or upload files at all.
2.) When directly connected to the router via LAN cable, I don't have any difficulties at all to send or upload files, meaning that the problem must be the Sonicwall TZ180.
What needs to be done to change the settings in Sonicwall TZ180 to enable upload again?
