C6300 Wireless Network shows up for a few seconds, then disappears when connected

Netgear C6300

 

Ethernet connection works fine

 

Wireless 2.4/5GHz are both transmitting (LEDs solid green). When I reboot/reset, the SSID networks will both show up initially. When my computer connects to it, it says "Connected, not secured", then drops. Both 2.4/5GHz networks no longer show on the WiFi list. 

 

I have tried rebooting, resetting to factory defaults, setting specific channels. 

 

I am using my phone and computer to verify. The 2.4/5GHz networks disappear after a few seconds

 

Has anyone experienced this and can comment? The router worked fine for 2 months (although suffered the intermittent drops for 15 seconds). Today it started giving me these issues when I bought a new Win 10 laptop and tried to connect. Now the router does not work for phone or laptops. I am 90% sure it is the router

Hello jtrading

 

I would suggest contacting support if the modem is still under warranty.

I have the exact same issue. The router has worked fine for one year connected to various Apple products, a smart TV, a PS3 and a Dell PC running Windows 10 with a Dell wireless card.  Tried to connect a new Lenovo PC running Windows 10 with a Qualcomm wireless card and my networks disappear.  Unfortunately, the moderators suggestion to contact support doesn't help me because I don't want to pay for support.

Hello finest14

 

Does the networks disappear for all devices or just the one?

Just the one.  PC with a Qualcom wireless adaptor.  Our Apple devices, smart TV, PS3 and Dell PC all work.  Took the other PC back to the store and exchanged it for a different brand and it works fine.  Not sure what the conflict was between the Netgear and Qualcom was.

DarrenM,

 

My router is experiencing the same issue, when I turn my Lenovo Yoga 710 on, the router craches and I need to reboot it. It just hapen with this computer(lenovo) all other phones tablets and computers work fine, and the Lenovo work fine on other routers.

Do you think updating the firmware helps?

If it is just the one device I would make sure that laptop has the latest wireless drivers.
