Author Topic: 4 x DCS-5222L Rev. B keeps disconnecting and bringing wireless network down  (Read 3702 times)

Cameras: Four (4) DCS-5222L Rev. B, wirelessly connected to router.
DNR-202L, connected to router via ethernet.
Modem: Arris T722G Telephony.
Router: WesternDigital MyNet N750.
Wifi security: WPA.
Other connected devices: 1 x iPad Air, 1 x iPhone5S.
ISP: Comcast Xfinity Internet/Phone/TV.

Comments: the router (WD N750) is a tried and true model for us. We have two units in two different residential properties and they perform well. The DCS-5222L Cameras are positioned in areas of the house where there is strong Wifi signal.

Issue: The four DCS-5222L cameras would drop wifi connection at the same time and are unable to reconnect. Only fix is to reboot the router; the cameras would connect, and work for anywhere between 5 minutes / through the night, then they would spontaneously drop the connections again and fail to reconnect.

When the cameras drop the connections, they also seem to disable all other wifi devices that were connected; the iPad and iPhone would not be able to access the internet, though they would still appear to be connected.

We have, at this point, ruled out the router as the cause of the issue, as we originally purchased a TP-link router with these cameras, which exhibited the same symptoms, and that prompted us to switch to a router that we know has worked for us for the past 3 years (WD myNet N750).

The camera resolutions are set to 800x480 and quality to medium to decrease bandwidth use. Their firmware were just updated to 2.02.06.

Please advise. Thank you.

  • What region are you located?

Wireless Configurations
Links>Wireless Installation Considerations and Managing Signal Congestion and Good Neighbour Policy
  • Ensure the default (dlink) SSID name is changed. Can be anything and not something that's already in use by any neighboring WiFi routers. Under Setup/Wireless/Manual.
  • What wireless modes are you using?
  • Channel Width set for Auto 20/40Mhz or try 20Mhz only.
  • Try setting a manual Channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear. 13 for EU regions. Try channel 48 or 149 on 5Ghz.
  • What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto TPIK and AES.
  • Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by?
  • Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many? Use v3, its free.


Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.

Does testing with one or two cameras at time still have the same problem?
