Title: Antenna Replacement
Post by: reddevil0728 on May 15, 2015, 11:39:22 PM

Can the stock antenna be replaced with a more powerful one?

If so how to find out which antenna is compatible with it.

Thank you.

The antenna are removable I believe. Not sure what other 3rd party antennas would be compatible though. You might want to phone contact D-Link support and ask...

Hello,

Sorry to dig the topic, but I am interrested and it's the same problem.
D-Link tells me that it is possible.
I think putting antennas 8 or 14 dbi.

Have you seen difference ?

Thanks.

What happens if you lower the resolution of the cameras? Still freezes?

Yes it's the same problem and the camera at the first stage is often disconneted.

Can you disconnect the DAP and connect the camera to the main host routers wifi and test? I presume if you still see the same problem, the camera maybe at fault here...

Cameras on the main router is the old configuration.
I had many problems of disconnection with cameras on the main router.
It's for the reason I pass by another AP. With a Trendnet or my D-Link, I have no problem of disconnection. Sometimes The camera at the 1st floor disconnects. But with the two others cameras I have not disconnection.

I have interchanged the camera 1 and 2, and I have the same problem on the camera 2 at the 1st floor.
With the 2 cameras in the same room of the DAP, no problem.
The 2 cameras at the 1st floor, sometimes the cameras freeze.
It's the same problem in 2.4GHz and 5GHz.

I have between -70/-80dbm at the 1st floor.
That is why, I think changing the antennas.

Any chance of moving the DAP to a different location and closer to the cameras?

Seems like this maybe a signal issue...
What channels is the DAP using?

It's the better location for the DAP and the 3 cameras. The DAP is in the middle of the 3 cameras and there is no obstacle. I tested with Wifi Analiser and I have better results at this location.
It's the channel 44. Same problem with 36, 48, etc. and there are not other network at 5GHz.

Ok. Not sure if this is a DAP or camera issue or a combined problem between these units.

I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email. I would start with the camera group first...
Let us know how it goes please.
