Does the camera need the network to be password protected? If not, create the guest network again, and for security in the wireless settings, select no security rather then WPA2. 

Other settings to try on the router would be to change the wireless channels to a specific value rather then leaving it on Auto.

Are you still having this camera issue? I have the archer a6 and can not get my wifi zmodo cams to stay connected. They will connect, then drop and just keep cycling. I also can not view the live feed on the zmodo app. Shows the cams to be offline.

@Tony I have

the same problem with simplisafe cameras

connecting.  Any help you can provide would be appreciated!

@Tony Same issue here. Ring Doorbell and Spotlight Cam work great, but the Indoor cam won't connect at all. Any suggestions?

@doughritto I too, have a very similar issue with the TP-Link Archer A8 router. I have two Zmodo cameras that connect to the network for about a minute. Then go "offline" for 20-30 seconds, then come back online. This cycle repeats until neither camera will respond. I did not have any problems with these camera until I replaced my router with this TP-Link A8. All my other 8 cameras area working just fine. There's something very different about these "Zmodo" cameras. I have been working with Zmodo tech support now, for several days. They cannot find the problem. I think they know the problem, but don't want to let the cat out of the bag, so to speak.

I don't like the way TP-Link has taken out a lot of router config options from those who are saavy enough to dig deep inside. They have "dumb-downed" the interface to save them from customers who get in there and mess it up. This is a prevalent practice now, across most industries, because the population is getting dumber year over year, and customer support is dwindling year over year. Too bad we are heading back into the Dark Ages. But, hey, maybe that's just me.
