Nighthawk x6 EX7700 randomly changes IP to wired connection from 192.etc to 169.etc
Hi, I have just bought a Nighthawk x6 EX7700 (2 weeks now). I am extending a router signal to my room where I have installed the EX7700. I use both the wireless (for the phone and a laptop) and a ...
The ex7700 uses the 5ghz as a dedicated backhaul. But if theres an issue with it, it defaults back to the 2.4ghz. Which might be causing it to give you a new ip address. Also, if you're using dfs channels, it might be defaulting back to the 2.4ghz while the 5ghz switches off the dfs channels.
That's why I recommend rerunning setup and disabling the "extend 2.4ghz network". Again, you'll still be able to use it, it just won't use it as failover. Just make sure when you've got the extender setup, have the 2.4ghz on a different wireless channel than the router to prevent interference. And make sure you're router isn't using dfs channels. Its supposed to be close to seamless when the router switches off a dfs channel but I've seen it cause slow downs on extenders.
Hi,
My problem is on the wired connection though. The wireless connected devices keep their 192.etc IP address. Only my PC that is connected via ethernet cable to the EX7700 gets its IP randomly changed to 169.etc. Do you mean that it's because of the 2.4ghz connection from the EX7700 to the router that this is happening?

Understood. Thank you for the clarification. I will do as suggested and let you know!
An update after some days of testing the proposed solution. I can say that in general it works. No more random IP address assignments to my PC whilst turned on.
But (there always is a "but"), it still happens when I completely turn off my PC (so "shut down" option, not "restart"). When I boot it up again the EX7700 assigns a 169 IP address. Not sure why at this point as the laptop instead did not have this problem when i tested under the same condition: wired connection to the EX7700 and shut it down for a few minutes.
If I then restart the EX7700 it assigns the correct IP address to the PC and it does not change as long as the PC is not shut down ("restart" is still fine).
