In my current condition I'm not able to open the router to check if it has dust etc. inside, Angie refuses to do anything that even remotely has something to do with repairing geek stuff. It looks OK, but that's just from outside.
I downloaded the update, flashed it. As soon the process is over, router reboots and the reboot loop starts again. There's a pattern there; it tries to boot 17 to 20 times before it finally boots. No less than 17, no more than 20. I set up my ISP credentials, am online from 20 minutes to an hour, and reboot loop starts again, reverting to factory settings. Credentials, half an hour online and so on.
Sending this tone o Belkin, warranty is valid. Trying tomorrow if I can manage to replace router, sitting in wheelchair and using one partly working hand. Why do it today if you have an excuse to postpone it, said my dear dad always.
P.S. Interesting, BTW, is that this only had happened before, sometime last summer, but now it's happened like 20 times in the past 24 hours.
