Got a D-Link DWR-921 4G modem/router which is used for remote monitoring cctv cameras. It has 2 removable antennas. Can anyone recommend an external antenna for this device in order to improve the mobile network connectivity?
Also, anyone know if its possible to have too many wi-fi cameras on a 4g router? Currently have 8 cams but they lose connection randomly. I suspect the router may be throwing them off the network, after restarting the D-Link router they all on again until randomly losing connection again. There appears to be no way to improve wi-fi on this device because the antennas are built in, only the 4G antennas are external.
Thanks
