On occaision, I am not able to connect wirelessly. My computer cannot even detect my wireless network. To fix, I log in to the router and re-save my wireless settings (without making any changes). The wired connection works perfectly. I have revision B with the latest firmware. Thanks.
It seems that there's a problem with the router's firmware. Try reloading the firmware for your router. Even though its the latest, the firmware you got might not be able to respond properly.
After reloading the firmware on your router, reset the button of the router for 30secs to properly load the firmware. After reloading the firmware, try to reconfigure the router try test again your connection.
NOTE: Please be informed that reloading a firmware could reset the router settings to factory default. Take note of the settings before reloading.
Thanks
