Hello,
I've had a C7000v2 router for a little less than a year now and I've created a problem. I change the IP address, use MAC address filtering, and disable the broadcast of my SSIDs; everything was working great until tonight. Something has come up and I needed to change my SSIDs so, idiot me, I didn't disable MAC address filtering before I changed the SSIDs and had to do a factory reset on the router because I couldn't reconnect. I thought the router would have saved my MAC Address list when all I did was change the network name but I couldn't get on the network wirelessly or wired, this may be part of the problem.
Now I'm having a problem with connecting to my 5GHz network. With the SSID braodcasting I can connect the devices I need on my primary network (Windows 10 computer, Ubuntu Server, Android phone, and wireless printer). When I turn off the SSID broadcast, all 4 devices lose the connection. I've gone through setting up the computer and server while the SSID is hidden but I get the "cannot connect to this network" message. If I turn back on the broadcast, all 4 reconnect automatically. I haven't turned on the MAC address filter yet.
The weird part is the 2.4GHz network works just fine both hidden and broadcasting on all devices, it's only affecting the 5 network. I'd move everything over to the 2.4 but my speed test shows the DL speed at less than a tenth of what I was getting on the 5.
Any thoughts?
