Extender issues after firmware upgrade

I have read a few post regarding issues with this ex7000 wifi extender and wish to share my experience. After purchasing, I set it up and all went well, good speeds and no issues. 1.0.0.62 was pre-installed and working fine. I upgraded to 1.0.0.66 soon after and didn't really take much notice of how my network was running but did notice a quality reduction and thought it was just my ISP. I since upgraded to 1.0.1.78 and immediately noticed issues with slow speeds, devices being kicked off the network etc. I also noticed that after a couple days, my PC which was connected to the extender, had reduced download speeds from 50mbps back to 5mbps but my upload speed stayed about normal. After reading some posts, I downgraded the firmware to 1.0.0.66 and tested it for a few weeks. The same thing happened to my download speed but everything else was stable. Today I downgraded to 1.0.0.62 and I think this has fixed all my issues. I am now getting the fastest wifi speeds (down and up) I have ever had through this device.

Anyone else who is having similar issues, I recommend doing the same. Thankfully this device doesnt automatically install new firmware so I will remain on 1.0.0.62 until a fixed firmware is released, that is, if there is ever a fix.

I'll have to say that this will be the last Netgear device I purchase because the support is poor and firmware should never be released without major testing.
