Just upgraded from 386 firmware to 388 couple of hours ago. Feel like I should do a factory reset, since these are two different "families" of firmware. However, so far nothing untoward has happened, everything is looking as I expect, good. Took a quick tour through the admin interface, looks just fine there, too.

We'll see over time.

Did a full factory reset before and after upgrading to 388.21099 from 386.49873, including hard factory reset on each 4 nodes (my OCD in play).

Only thing I can see is that free RAM went down a bit from 209 MB to 199 MB.

Will stay with this FW until GNUton's next release.

Note that doing a full reset before you flashed the firmware you want to use is not ordinarily needed.

Good morning,
I have a problem with my XT8 after upgrading to or
The last stable firmware for me is
My node loses communication with the main unit, the LED light is yellow and I loose connection or it is very unstable.
I did a hard reset but it didn't help.
The main unit is on the first floor of the house and connects to the nod on the second floor wirelessly. I did the test by putting both units side by side - same story; yellow LED light and lost connection.
What could be the reason? Which settings should be changed to restore connection stability with the latest firmware?

Just dirty upgrade my router and my node.....node all went fine, router needs to be reset (not factory reset, just power cycle) to connect 5ghz-2 wifi devices to internet

Sometimes mac filterings doesnt apply correctly

so far problems with this firmware update

i just review over in status shows wan/lan ports status and usb icon too

A small annoyance: doesn’t resolve for me now. Any ideas why? I can reach with so no big deal but a weirdness after upgrading.

No major issues so far, but it doesn't feel as stable as on 386.49873. The only quantative metric I can do is seeing TX/RX transmit rates between 2 nodes on 5-2 backhaul and they are fluctuating up and down whilst previously it was static for weeks in a rows... I will stay on this for a week and then downgrade to compare again.

That is in the iOS or Android app.

Yes, feature 3. above is found under "Notification Settings" in the Asus Router smart phone app.

Upgraded using the app from 48706 and only the main node updated for some reason. Tried few times using the app to update second node but didnt work. Even rebooting and trying to reset didnt work.

I did a firmware rescue and flashed directly the latest firmware and worked.

So far seems stable and getting higher speeds. Was getting previously around +500 to 550 mbps and now getting +700mbps.

I got 1gbps fiber connection and using ethernet backhaul.


New Around Here
I recently upgraded and for about a week, all my nodes were disconnecting once every day and takes a while for them to reconnect if I don't manually restart the main router.

Main reason is probably because I have 9 nodes in total of varying models and those other nodes have not yet been upgraded to the 388+ family so there may be a compatibility issue.

Downgraded to 49873 for the meantime until Asus rolls out 388 updates for the other models.

To give you guys a clearer picture, here's how my topology goes:

4 XT8s (1 main, 1 wifi backhaul, 2 ethernet backhaul)
4 XD6s (all ethernet backhaul)
1 TUF AX5400 (ethernet backhaul)
1 TUF AX3000 (ethernet backhaul)

Dirty upgrade on my two installations (4 xt8s in one house and 2 xt8s in another).
No problems at all.
Never made a factory reset from the first firmware I used (42095)
