Printer is staying awake and phone battery drains overnight.

[KGB7]

Router: Asus AC68U. Firmware Merlin 386.14_2

I have a cell phone and a printer connected to the router via 2.4ghz band. Phone battery drains quite fast even when its not in use and printer never goes to sleep despite manually changing the settings in the printer to sleep after 30 min.

In the routers wifi advanced settings I have tried changing DTIM Interval between 3- 12. Beacon Interval between 100 - 1000. Only thing I haven't tried is performing full reset of the router or reflashing the firmware for the 3rd time, which I should probably do, but to be honest I don't feel like setting up all the settings from scratch right now.

Any suggestions what could be the issue? Cheers.

Edit: I connected the phone and printer to 5Ghz band this morning and now I just have to wait a few hours and see if there is a difference in battery life and printer goes to sleep.

weak wifi signal or interference from neighbors causing both to hunt for the station are likely causes. 5GHz reaches less distance than 2.4 GHz, so maybe make it worse or no better. Put the phone in airplane mode at night and turn off wifi on the printer. Turn it on when you need it. Otherwise, relocate where you can confirm strong signal from the AP/router.

You gave me an idea that I'm going to test. I changed from Channel 6 to channel 11 and reconnected both devices to 2.4Ghz band. I should have an answer with in an hour.

When I connected both printer and phone to 5Ghz band earlier this morning, printer went to sleep and battery on the phone stopped dropping.

Unfortunately the phone is still draining on 2.4Ghz band but the printer does fall a sleep. Guess ill reset the router and set it up from scratch again.

Keep Beacon at 100, DTIM at 3 - this is generally good enough for most...

I would look at clients driving traffic into the WLAN with broadcast traffic - the printer is a key suspect here, maybe reset to back to factory and reassociate it..

Even when the printer was on 5Ghz band and phone on 2.Ghz band, phone battery was still draining. Over night I turned off my router and batter on the phone dropped only 1%. But while phone connected to 5Ghz band battery drained slower compared to 2.4Ghz band.

No traffic going in and out on 2.4Ghz band, phone and printer is the only two devices connected to the router, everything else is on 5Ghz band and one devices connected via LAN.

Something funky is going on with the router, because it wasn't an issue with AX68U router.

I'll just reset the router and see what happens. Thanks.

Try disabling wifi on your phone for a bit to see if the battery discharges at the same rate.
Maybe it's just time for a new battery/phone?

I turned off my router over night and my phone only lost 1% of the battery. So it's defiantly not the phone or phones settings. Everything in the phone is turned off and disabled so nothing runs in the background.

I did performed "forget network" in phone settings, reconnected to 2.4Ghz band and after an hour lost 3% of the battery while phone was not in use. I just need to find half an hour to reset and reconfigure my router as the last resort. I was hopping I missed a setting in the routers wifi.

Weak cell phone signal can drain a phone battery likity split.
Is the phone wifi only or cell service as well ?

Just saw your latest post. i keep wifi off on my phone until i need it for just this reason.

Battery drain on my Pixel 6 only when connected to RT-AX55 router

Since last week, I get battery drain on my Pixel 6 but ONLY when connected to my home WiFi on an Asus RT-AX55 (not over data, not over other WiFi networks at friends or family). Battery analysis shows that, when connected to my home WiFi, the phone almost never enters Deep sleep mode...

One other thing to consider - reset the printer, I've had that happen before with an older HP wireless printer, and it was sending crazy traffic over wifi - powered down the printer and the traffic went away...

I have an update and a simple fix for the problem I was dealing with. I enabled AMPDU RTS and kept default setting at 2347, and no more battery drain on my cell phone. It's been about 4 hours and zero battery drain.

Quick update.

Woke up this morning and the battery on the phone was still at 100% while connected to the router. Restarted the phoned the battery went down to 98%, which is fine.

That was a weird bug which im glad is resolved. But I guess im to blame for extensively messing around with the settings one day even though I powered cycled the router several times. Oh well, live and learn.
Cheers.
