I've had the Xr1000 router for a month now with no issues until a couple of days ago when the powerline next to my house decided to blow up and the power got shut off for a couple of hours before someone from the electricity company came to fix it. After that, when power came back and the router was up I couldn't login to DUMA OS. I would get this error message:
haserl CGI ErrorFailed to readline from 'config get DumaOS_Theme_Version'
So I looked it up and one of the suggestions was to reboot the router so I did with the power button on the back and the router had "factory reset" in a way on it's own. The network name and password and all the settings like smart connect were back to factory but the custom device names I had given to each device in the device manager were still there. I did a full factory reset after that thinking wth might as well set everything up again and reboot the router with the new reboot option in the OS.
Why? for 3 reasons,
1) I wanted to test it out since it is fairly new
2) in another post regarding a similar issue OP had the same problem occur again after a reboot and I wanted to see if it was fixed.
3) I needed to know if the power goes out again at some point in my life which it most definitely will or I have to disconnect the router to move it or whatever if this would happen again.
After the reboot same issue occurred I couldn't access the DUMAOS again so I had to reboot from my phone this time which reset everything and so now force updated the OS with the same update 220.127.116.11_1.0.38. I won't do a factory reset however just yet and also won't reboot just cus I don't wana set everything up again incase the force update hasn't fixed things.
Basically if you reboot once, you can't access DUMAOS and you get the error message I posted above. so then you have to reboot a second time which factory resets the router for some reason but in return allows you to log in to DUMAOS and fixed that error issue.
Now my question is do we know if this is a hardware issue that may have caused after the power outage while considering the fact that someone else in the post I linked has a similar issue and OP didn't have a power outage to potentially have damaged his unit. Or is this a software issue and we just have to deal with it in the mean time and hope to get fixed at some point? Cus if it is hardware, I would like to know to see if I should get a new one but if it is software I would just suck it up for now.
