    Hi,
    I recently upgraded my RT-AC87U for a RT-AX88U, and while the 5ghz WiFi seems good, the 2.4ghz seems worse. It doesn't seem to go as far as the old router.

    Has anyone else found this?

    Thanks

    This was discussed in this thread. There appears to be an issue with the recent firmware(s). Going back to an older release should sort it until Asus fixes it.

    Any firmware after 384.14 is being affected. Stay with 384.14 for reliable 2.4 ghz performance.

    Thanks for redirecting me, didn't know about this, thought I had a faulty unit or something.

    @Hawk
    Thanks for the advice, is it safe to run an older version, has there been any major security fixes between the versions?

    Thanks

    Changelog doesn't show any major security issues, if you decide make sure to keep security tightened around router example no wan access, no ping from wan, disable upnp etc.

    I've moved to .14 and I'd say it improves by 10-15db which I'd say is pretty close to what my RT-AC87U managed. I also noticed that when running .15 it would use 40mhz for 2.4ghz WiFi, but when running .14 it uses 20mhz - same settings.

    Has there been any word from ASUS regarding this issue?

    Thanks

    Asus are aware of the issue, it seems the driver used to control radio got messed up, when tweaking MU-MIMO. I am hoping they release new driver which fix this bug.

    Hopefully, affects my gt-ax1100 also. 2.4 is awful on this. (Only affects my playstation vita, so not massively fussed, but still..)
