Log Indicates Router Restart

I am running Vista Home Premium and have a D-Link wireless router to connect
other PC's and laptops in the house. I have recently noticed in the router
log that my router has been restarted. This befuddles me as the power has
not been interrupted, I have not made any changes to the settings and saved
those changes, and have not restarted the router myself. I currently use the
following wireless security measures, 1) SSID broadcast set to off, 2) Open
WEP 128bit Hex encryption, 3) MAC Filtering with 3 MAC's allowed, 4)
Disabled UPnP, 5) Disabled WAN Ping respond, and 5) default username and
password changed.



Any ideas as to what may be causing this?



Thanks in advance

Hiding the SSID is no real deterrent, nor is mac filtering. WEP also
is not safe. I'd recommend WPA2 or at least WPA.

That said, some routers can reboot when under external attack. Or a
brownout or undervoltage can do strange things.

Hi
Actually it is not such a bad thing warm reboot clean the memory from GIGO
and the Router works smoother.
However if it keep doing it I would look into new hardware, it might
indicate hardware problem.

How do you know for sure that there's no power interruption? Is the device
connected to battery backed power supply (UPS)?

I agree with everyone else... bad security but hey, it's your network.

FWIW, I have a D-Link DSL-302G ADSL modem/router. It has two
supervisor ICs, one to detect the Vcc of the CPU, the other to detect
the unregulated +12V supply from the AC adapter. AFAICS, it should be
possible for the CPU to keep going during a brownout while being aware
that the AC power has dipped. Perhaps the modem does some emergency
housekeeping when it detects an AC power failure.

well, if you can't completely rule out power failures, that would be
my first guess. anything in the router log of interest?

It can't hurt to get a UPS device that provides backup power and see
if that makes a difference. If it does, then you avoid the headache,
if it doesn't, it may be time to replace the equipment.

I should qualify my previous post by first agreeing that behaviour
during a brown-out can be unpredictable. Secondly, I've seen a photo
of a D-Link DSL-500G or DSL-502G modem which uses the same circuit
board as my own DSL-302G, yet it omits the second supervisor IC, ie
the one that detects a dip in the AC supply. So one flavour of the
same PCB is aware of AC power failures while another is not.

One clue as to the nature of the OP's problem may be in whether the
log is stored in volatile or non-volatile memory, and whether there
are any entries preceding the reboot. If volatile, then one would
expect that a "cold" power-on reboot would clear the log whereas a
"warm" reboot may or may not.
