RT-AX88U won't upgrade to 386.8

[Col8eral]

Tried updating my fw to merlin 386.8 but after upgrade still shows version as 386.7

Anyone else had this problem?

What actual model router is this?

 

[Col8eral]

It is an ASUS RT-AX88U

You should edit your thread title.

Try safely removing (via the GUI) all USB devices. Reboot the router and try again.

I'll give that a try. Will report back.

That worked. Thank you.

All previous FM updates were done with the usb drive connected and they worked fine.

Out of interest why does a connected usb device cause this kind of problem.

Thanks again

It may vary from instance to specific instance, but it is mostly because the router doesn't have enough free RAM to load, extract, and verify the firmware file it is trying to flash onto itself.

Many thanks. Much appreciated. All installed perfectly now
