Hello,
I have a D-Link DSL G256DG router which was provided to me by my ISP, could not find a manual for the router anywhere.
Its firmware version is BZ_1.00.23.
In my home network, some WIFI devices are associated to the router via the 2.4GHz band and some devices are associated to the router via
the 5GHz band. The router is configured with DHCP enabled. each band has its own SSID (using same SSID did not help).
IPs are granted to the devices by the router, both to the devices on the 2.4GHz band and to the devices on the 5GHz band so actually all devices are on the same sIP network: 192.168.0.XX with subnet 255.255.255.0
Problem: devices which are associated on the 2.4GHz can ping each other, devices which are associated on the 5GHz can also ping each other,
however a device which is associated on the 2.4GHz band fails to ping a device which is associated on the 5GHz band. It seems that some routing between the WLAN interfaces / BSSIDs is missing. all devices show that their default gateway is 192.168.0.201 (the router's IP internal maintenance IP).
This is a major problem as for example my WIFI network printer can associate only to the 2.4GHz band so devices which are connected on the 5GHz band can not access it and print.
Appreciate your support. Maybe a manual is also available.
Regards,
MKDS
