R2 hangs up

[Guest Deng]

Ok, changed to 168.

[Guest Deng]

Unfortunately I've had to disable remote support because logs were spammed every second with:

Thu Sep 23 07:08:49 2021 authpriv.warn dropbear[20369]: Bad password attempt for 'root' from 47.94.46.179:45172

and there's no firewall to cut them off the router.

[Netduma Fraser]

That's absolutely fine, just keep us posted on whether the DHCP change helps. There is a built in Firewall on the router so you will be protected.

[Guest Deng]

Ok, so we could hang up the router twice in a row by sending and arranging photos in Google Photos on iPhone.

Unfortunately my wife disabled wifi for a moment after the second restart and we cannot reproduce it the third time.

It also hanged up when using Google Photos on iPhone one time a few weeks ago she says.

[Netduma Fraser]

Thanks a lot for the information, how many photos were you sending roughly and what were the size of all the photos combined that you sent? Then our team can try to reproduce the issue and implement a fix.

[Guest Deng]

Around 20 photos with "live" function or what it is called in ios.

Background backup with rearranging the galleries.

[Netduma Fraser]

Great thanks a lot, I'll pass that onto the team.

Just mentioning - after those restarts adblocker lost its configuration again (whitelists, was disabled completely etc.).

That's bizarre, you didn't have to run through the initial setup again after this did you? Were your whitelists removed or just disabled?

[Guest Deng]

No, it's just adblocker acting up.

I've had to set it up again - enable it, make a whitelist again (I was prepared this time) and disable for some devices.

It did the same like a month ago after one of the powercycles.

All the other functions are ok.

[Netduma Fraser]

Before you power cycle reboot from the interface, this acts as a hard save, then after it's loaded up again you can pull the power if needed and everything should be saved.

[Guest Deng]

@Netduma Fraser I understand, but I only powercycle after there's no option to connect to it

And of course I rebooted it a few times manually thus saving the config.

[Netduma Fraser]

Interesting, as its one of the newer features it may be that it is not saving properly when power is lost even after a normal reboot. I'll let the team know and see if they can reproduce this.

[Guest Deng]

Ok, so I could crash the router a few times in a row.

My wife enabled wifi, Google Photos on the iPhone started to backup the photos and videos, everytime it started to send the backup it hanged up the whole router in the matter of seconds.

I wanted to grab the exact moment in the logs and I did. But unfortunately no logs were written/displayed, it just shows as hanged up - CPU usage lines freeze and everything becomes unresponsive.

I repeated the process a few times even recording the moment on the video, I don't think it will be much helpful but if you want me to share it then PM me.

Best regards

[Netduma Fraser]

That would be good if you could provide the video for the team - is there anything personal in the video? I won't be available tomorrow so the team wouldn't see it so would be best to post it here if possible.

[Guest Deng]

I feel somewhat uneasy about sharing it here, personal details or not

You can send it over to us via email if you'd prefer? Just send it to [email protected] and let us know here if you're happy to do that.

[Guest Deng]

PM-ed you the clips in another topic.

Regards

[Netduma Liam]

Thanks for that, it does look as though the CPU usage graph freezes when you started the backup. 

I'll get back to the team and see if it can be re-produced.

[Guest Deng]

Today at night it died again. This time reboot fixes only the connections but the web interface is unavailable, will try to reset it to the factory settings later.

[Guest Deng]

It works fine after resetting it to factory settings.

OK, thank you for letting us know. 

Presumably you're still getting the same problem with Google Photos uploads after resetting?

[Guest Deng]

Hey Liam, I cannot easily reproduce it. Sometimes it hangs up the router every time you try to backup photos but most of the time it works just fine.

My guess is that when you try to backup lots of photos there's something wrong. Will see when the next problem arises.

OK sounds great, thank you!

Still crawls to the stop.
