Question

d-link dir-615 rev E4, DD-WRT v24-sp2 (03/25/13) latest firmware.
It works unstable, the network, local and Internet, periodically falls off. There is nothing special in /var/log/messages. How to diagnose and solve the problem?

Answer 1

Maybe the power supply is failing?

Answer 2

It disappears on this piece of iron when uTorrent is actively downloading, it creates a lot of connections, the piece of iron, as it turned out, is not rubber. At the same time, uTorrent downloads OK: up to 11 Mb / s, fast and stable, but http does not respond ... I can’t reach the router itself (192.168.0.1) at all ...
=> I cut the number of connections, and I endure it.

Answer 3

In general, d-link dir615 is dead, temporarily installed dir-320 with native, newest firmware. at the moment the flight is normal (a couple of months).
