Yep, this is weird.
One curious thing I noticed was that when I used my old settings the router crashed much more frequently.
Software settings do seem to have some impact...
This is what I did:
- Router (ver 1.74) crashes within 2 minutes, when using HDD (fat32)
- Format HDD to XFS with router, still resets often
- Update firmware to 1.77, still resets often
- Take backup of router settings
- Do factory reset (bootup, press and hold the small button on the bottom of the device)
- Reconfigure wireless
- Router crashes within 20 minutes when using HDD
So software does something for this, now it takes much longer before crash.
