I have a problem with multiple network cameras connecting via Wi-Fi to the same AP. I have an AP (TP-Link WA901N for now. I have tried others with same error.) and two cameras currently.
One is indoors near the AP, the other is outside in my yard. Both when connected to the AP individually report low latency (2-20 ms) with 0% packet-loss. Even while viewing the cam.
The minute I connect both devices simultaneously to the AP, packet loss and latency increases highly shortly after. (500-600ms, 2-30% PL). At first I thought this was due to my old AP not supporting MIMO but this unit does.
Attempting to negotiate another wireless client onto the same AP also has latency on that client. Disabling and enabling WMM has proven to not be effective at all.
Moving the indoor cam to another AP in the house alleviates this for now, but I would like to be able to support multiple cams on that same AP. Bandwidth used from both cams simultaneously is likely 2-3 megabit or so nothing crazy.
What can cause this behavior with multiple APs, etc? I have a feeling it may have to do with signal strength (No way to tell with this firmware on this.) but using my laptop in the same spot as the outside cam gets me over 25 snr so I'm not sure.
Is there anything I can do to mitigate this from occurring?
