What confuses me in above setup is that the PC and WLAN AP+SDS seem to be on a different subnet.
The SDS is at 192.168.0.1,
The Wlan AP is at 192.168.0.254, (providing subnet via dhcp 192.168.0.100 to 192.168.0.254, as per manual).
While the computer seems to be at 192.168.4.70.
So... (assuming a subnet mask of 255.255.255.0)
SDS is on the subnet 192.168.0.x
WLANAP is on subnet 192.168.0.x
PC is on subnet 192.168.4.x
Both subnets do not see each other, therefore the PC will not see WLAN AP and SDS.
solution 1:
If this is the case, a (manual) route needs to be set between them both subnets, therefore a router is needed...
(so assuming you use an internetmodem+WLAN AP, this would be in the internet modem)
OR
Solution2:
All need to be moved to the same subnet...
