both my printer and my PC are connect to the router (DLink DIR-605L) using WIFI and internet is working on my PC. My printer works only if I connect my PC to router over a ethernet cable but it doesn't if I detach the Ethernet cable. the firewall software (SPI) on my router is disabled. Does anyone have a idea why this is happening?

configurations:

PC: DHCP
Router: 192.168.0.1/255.255.255.0
Printer: 192.168.2.222/255.255.255.0

  • I doubt your router will support 802.11b unless you specifically configure it to. 802.11b is ancient and many wireless networks refuse to support it because it imposes costs on other devices.

Sounds like the router may be configured to only allow a 802.11b connection when it won't impact any other devices connected (which is when the only other connected devices are 802.11b, or there are no other devices connected).

Is it possible to get an ethernet cable to the printer?

You could probably configure the router to allow 802.11b to run actively all the time, but it will cost you performance (probably significantly).
