TD-W9980 Firewall blocks wireless traffic to LAN
Hi I am having a problem with my ageing TD-W9980 wireless router whereby it is blocking access to my LAN from wireless devices. I recently added a wired NAS to my LAN and can access it fine from any ethernet connected device but wireless connection fails as host unreachable, I cannot ping the NAS from the wireless lan either. When I turn off the router firewall it connects fine so I thought it would just be a matter of adding a specific rule to the firewall. However, whatever rule I apply it still blocks WLAN to LAN traffic. I had the same problem setting up a wireless printer and in the end I gave up and attached the printer by USB. Can anybody help me sort this out please?
Oh I forgot to say internet access from the wireless devices is fine.
