EX7300 wifi range less after upgrading to latest firmware

[kessency]

Since upgrading to the latest firmware, the wifi range is now less than the previous firmware.  I am using the same channels as before.  Plus, I had the move the EX7300 closer to the router to get a reliable signal.  Has anyone had this problem?  How do I revert back to the previous firmware?  I am using a Macbook Pro with Retina display and running High Sierra OS. Thank you

Here is the support pages with the older firmware

you will have to log into the extender and manually add the old firmware.

DarrenM, thank you very much for the site for the download for the previous firmware version.  My range and speed are back by rolling back to the previous firmware (1.0.1.78).  Not sure why the new version (1.0.2.136) lost performance, but I am happy now.  Thanks again.
