Wifi Troubleshooting
If the camera does not connect and you’ve already checked the settings
mentioned on the previous page and you made sure the antenna is connected
properly, please log in to your router and double-check the setting for wireless
channel selection. On an Apple Airport you would use the Airport Utility.
On N mode routers other than current Apple routers be sure to turn off “ wide
channel spacing ”, sometimes also referred to as “ 40 Mhz mode ” or “ up to 300
mb speed ”. This is not compatible. You should use “ standard channel
spacing ”, also known as “ 20 Mhz ” or “ up to 130 mb speed ”. Mixed 20/40 Mhz
should be avoided. (Apple routers no longer allow the wrong setting)
If the “search” function of the wireless setup page found your Wifi network it
means that the wireless networking hardware is working. If it then doesn’t
connect it means that there is a password or IP address related issue.
You can temporarily turn off passwords on your Wifi router, and if you then
set “Security mode” to “off” in the camera, it should connect unless you have
set your router to reject connection attempts from unknown devices.
Assuming that you are now at least connecting without passwords, you can
proceed to add wireless security to your router and try again. We recommend
WPA2 if available, otherwise WPA. The older WEP mode is obsolete and may
not work correctly on Apple Airport. If you have trouble, switch to WPA2.
Since each password type can have 2 variations, this means you could have 4
possible combinations: WPA-TKIP, WPA-AES, WPA2-TKIP, and WPA2-AES. Only
WPA with TKIP and WPA2 with AES are valid, the others will not work reliably.
Some routers like Apple Airport series do not show clearly which one of these
settings is being used, so if you have difficulty you should try both WPA + TKIP
and WPA2 + AES. On a laptop you typically do not need to specify the exact
password type since the laptop will try all everything automatically. The
camera is more picky, it needs to know exactly what type of password you are
using. It does not try anything other than the exact type that you entered.
Remember to “ Apply ” first, then “ Test ”. If it says “ Connected! ” at the end of
the test, you can remove the cable. Please note that as long as the cable is still
attached, the camera’s “
System ” menu will show “ No wireless connection ”
since you are still using the wired network and only one network can be active.
If you still have trouble, be sure to check the Appendix for known issues.
