Recently I had done update of the firmware to the latest version. But after that update, I noticed that the router admin pages are loading slowly.

Hence, I decided to go for a factory restore using the hardware control i.e press the reset button using a pen.

After, factory restore the LED light for POWER is continuously blinking. Then I did some google search and found that TP link firmware have to downgraded and hence, I downloaded it from TP link website, uploaded the firmware using cable and everything is back to normal.

Lost my precious 4 hours in troubleshooting this issue which shouldn't be there in the first place. 

My question to TP link is - Does it not test its firmware before putting it in production ?

Why does latest firmware is not available for download from the download center in the TP link website ? On top of that why does TP link recommends to update the firmware if its not putting its latest firmware on its website ?
