Hello. i intermittently could not access my camera and receive this message: "abnormal network". what's weird is that i have two cameras installed at home (one near our wifi base router on the 1st floor and the other on the 2nd) and this thing happens to both of them and i had to reset the affected unit each time. i don't think that there is a problem with our internet connection because it only happens to either of the two at a time while the other one works. please help.
