If you are having issues with your RT61 wireless card on a Linux system and are not getting any scan results, there are a few things you can try:
Check the wireless card's driver: Make sure that you have the correct driver installed for your RT61 wireless card. You can check the installed driver by running the lsmod command and looking for the rt61pci module. If the module is not listed, you may need to install the driver manually.
Check the wireless card's firmware: The RT61 wireless card may require specific firmware to function properly. You can check the firmware version by running the iwconfig command and looking for the Firmware field. If the firmware is not present or is out of date, you may need to update it.
Check the wireless card's configuration: Make sure that the wireless card is properly configured and that the correct wireless network settings are being used. You can check the configuration by running the iwconfig command and looking for the ESSID field. If the ESSID is not set, you may need to configure the wireless card manually.
Check for interference: Wireless signals can be disrupted by other devices or physical barriers. Make sure that there are no other devices or objects that might be causing interference with your wireless card.
If you have tried these steps and are still experiencing issues with your RT61 wireless card, there may be other factors at play. Consider seeking additional help from the community or consulting a technical support resource for further assistance.
