Well, I have an outdoor security camera with audio (Sharx brand from Amazon), and two Trendnet interior units with two way audio, running all of the time. My son plays online gaming and we stream netflix and do usual web browsing. No slow down in speed. We have FIOS with 80Mbps up and down, so maybe you don't have enough bandwidth? You might want to check your speed via www.speedtest.net. If you have less than 10-15 Mbps download/upload, a camera being on could cause issues. You might also consider tamping down the camera quality for streaming - and make sure you have changed your camera password so others aren't watching it using up your bandwidth. Just some suggestions/thoughts....good luck....this is a great router allowing full speed!
