R7000 DHCP offer but no connection can be made on 5Ghz band
R7000 Windows10 / Android Firmware = 1.0.7.2 Modem = 192.168.0.1 Router = 192.168.1.1 (R7000) Hi I had a horrible weekend getting my R7000 to work again after replacing the modem from the ISP. ...
Welcome to the community, ringlord
Sounds like a faulty router.
Can you try the following reset below then reconfigure the router.
1. With the unit powered on, press and hold the reset button on the back of unit for 30seconds.
2. Without releasing the reset button, unplug the unit and hold reset for another 30 seconds.
3. Power on the unit while STILL pushing the reset button and count for another 30 seconds before letting it go.
Try to reconnect your devices on 5GHz and see if it will work.
PS This is what we can see in the log :

Thanks ElaineM it has been a rough ride with this router.
Your reset procedure seems to have helped quite a bit since I now can connect on the 5Ghz band but I am not yet completely convinced that the connection is stable since I sometimes still get network connection errors for example on my Nexus 5.
Also the speed of 50/6 on the 5Ghz channel is less then I used to get.
I append the new logfile here so you can see that still multiple DHCP offers were needed but eventually the connection succeeded.
The odd thing about this reset procedure is that my settings were retained. (I tried it twice with the same result)

If it keeps disconnecting, try to check for other channels.
You may also want to try to adjust the Fragmentation Length and CTS/RTS Threshold to 2304.
Then reconnect to the network.
