router resets

[Chris_Tucker]

Is it normal for a router to reset about once a day? on its own?
I've only noticed this in the second half of this summer.
I have a DI-524, and it resets about once daily, though sometimes it skips a few days. Not really a big problem but it is a bit slow to reset, its off just long enough to terminate most connections...
I have the newest (last i checked) firmware for the unit, and what sucks is that i can't tell if its resetting in an attempt to get a new IP from the ISP due to an attack/flood, because when it turns off it erases it's logs.

Though, it could be as simple as being because i have routed dialup not highspeed right now, untill i move (1 week :D). Right now its a hacked together system, using a ubuntu machine thats always on with a modem in it, two network cards, one to the WAN port and one to a regular one, with a mess of iptables forwarding all incoming requests to the WAN port of the router (acting just the same as a modem would, cant access ANYTHING on the modem box from the outside), and therres always been an issue with my dialup provider and returning ping requests... for instance if i try to ping google.com, it will dns resolve, but never reply, same for ip's that are home systems that do not have ping blocked., so it could be just this, and nothing at all wrong with the router....

I've noticed that the thing resets itself about once an hour if you remove the antenna (i know this because i have a spare router i move around, wherever i need wireless where there is none, and i broke the antenna, so i swap it around) untill you give it back its antenna, my guess is theres a sensor so it knows if the wireless is outputting at the right dBm that is set in the config... but i dont think this is causing the overall problem as the wireless still works perfect, no drop in signal anywhere where ive tested it when it was working fine.

any ideas?

what about ventilation? make sure it's not feeling/getting hot when it's reseting. I had an old DI-624 that would overheat and freeze. trying to mod it with a HD cooling fan to see if I can revive it.

Replaced with a new DI-624 that would freeze the wireless on me when it was new, and after about a week it finally settled in.

If you are using Modded firmware, look for the Mode called "AP WATCHDOG" This comes as default "OFF" on Linksys Routers, although i do not know much about D-Link.

The AP Watchdog enables a timer that will check to see if any clients are connected in the interval seconds given. If no clients are attached, the watchdog assumes the AP needs to be reset. When clients are connected this reset will not occur. The watchdog is intended for situations where the AP becomes unavailable due to interference or internal chip problems.

[Chris_Tucker]

No idea on the modded firmware, didnt think that stuff worked on d-link.
as for heat, the thing is warm, same as it always it, not hot. but i would suspect the chip inside is mighty toasty for the plastic to be warm... so thats a possibility (only checked the top cause its wall mounted, havent checked the bottom, which is closer to the chip.

[DodgeMan79]

how old is the router any way. btw, there are only two screws, atleast on the di-624, to remove the top. two chips should feel warm, but not hot. my current di-624 is overall warm with no warm-spots.

also if you listen closely to you hear a high pitch whine, similar to when a tv is first turned on the the capacitor starts to charge. mainly you hear it on older tv's.

the wine is a yes, and yes, there are only two screws. Ive had one my di-524's apart before. Its overall warm, except one end and the back (the back is probably cool cause the metal casings of the ports)
I'll take it down later today, pain in the ass to do it cause i have to use couplers to extend some of the wires to check it while it's on... most of the cables are clipped to the walls up to that spot so i cant get any slack out of them. and i have to remove the shelf of my desk to get it out too :/ (screwed up on my measurements when putting it in)

i'll post the results later... it still seems to be rebooting, according to the log it did it yesrday at 4, while i was gone for a while.

I've had my share of problems helping people out with those DI-x24's as well. One of my friends has a 624 that constantly resets (he thought it could have been a bad router and swapped it at the store as well)...the odd thing is that usually only the wireless drops on it.

In the other case (for one of the families I help with computer work for), it had a habit of randomly dropping and resetting in a manner to yours (though usually at night when they weren't on). Their DSL provider gave them a new modem (2wire, with built-in AP), so I took the D-Link out of the picture and shoved it in a box as a backup, and gave the 2wire all the settings the D-Link had (SSID, security key, etc.) to make it easier on them. I haven't heard a complaint about it since.

Point being...those are pretty cheap routers, so I guess you get what you pay for. You might want to look at trying something with a better track record. Or else, set the router to act just as an AP (turn off DHCP) and set the Ubuntu dialer box you have up to take care of that. It might help out a little bit...key word being might.

Dont forget, im moving in a few days, so that dialer box wont be there anymore, its staying behind. So thats out of the question, and i dont have another system i can connect in a similar matter....
still testing this one, soon going to copy it's settings to the spare and swap them, see if its burning out...

[DodgeMan79]

if you hear the whine, then you might want to keep a spare on hand. that's what happened to my old 624. it eventually kept rebootin and freezing until nothing worked but the wired ports.

since this is my third 624, first one is at parents house still working like a charm, I have to agree that d-link is ok. it's the run of the mill inexpensive router. after my current d-link dies then i'm going for linksys. i've seen nothing but great reviews from end users on the board here about them.

[Chris_Tucker]

so the wine is bad?
all my network hardware has that high pitched sound... since i bought it... as far as i know its safe!? even my switches have it... its not loud, have to have everything else in the room off, and no noise coming from outside the room to hear it, and even then thats with your ear to the plastic...

[brian_holiday]

A high pitched whining? That isn't good. You should take a component or two somewhere else and see if it goes away (like work or school). That whine could be a power problem. Is there a box fan or something on the same power circuit?

[Chris_Tucker]

No... and its very faint... as far as i know something you'd expect to hear from a complex electronic when theres no noise around... as its VERY high pitched, almost unhearable.
If i were at school already i could check the thing in the lab (electrical engineering student) if i heard the wine there even (would be hard to hear over the A/C though) i could check the DC power coming from the power brick with an ossiliscope to see if there is a waveform happening.... but i doubt it

[DodgeMan79]

when mine started the whine you could be about two feet away and hear it. so it was pretty loud.

The problem is back. and now its more annoying than ever.
I'm on highspeed, i have a total of 5 computers on my network at most times, sometimes just 3, (2 are laptops.) 1 is my server.
Now heres where things get confusing.
I have highspeed, its adsl, 5mbit, and they send all new customers a new modem/router combo, the speedstream 6520 with their own firmware in it. I have tried to solve this problem with 2 configurations. When i use their unit as the router, its the one that resets, and thats where it got annoying, because every reset gave me a new internet IP. Not fun when you run a server.
So, after calling them, hard resetting the unit, and reconfiging it, and it resetting on me just as often, i changed things:
Right now the speedstream is set up just like a modem. and i have one ethernet cable connected to it. that goes the the WAN port of the OTHER DI-524... if you read this thread entirely, the di-524 it mentions before this point is another, the one im using now is a slightly newer one, but still not the newest hardware revision.
Anyway, the di-524 has a static wan ip, and thats dmz'd in the speedstream. all that works fine.
But now the speedstream is stable, and the di-524 is whats reseting... usually once to twice daily, sometimes it skips a few resets, same that the speedstream would do when it was the active router.

any idea on what could possibly be causing this? its obviously some kind of traffic that kicks the router in the ass...

systems are winXP sp2 (all the windows machines are this) and 1 linux system. the os doesnt seem to play a role when it comes to the server, as its been a few different things during all of this.
And it also doesnt seem to be a firewall type issue, because the di-524 is dmz'd in the speedstream, but before that the server was in the speedstream's dmz, and now the server is in the dmz of the di-524... so in all cases all the traffic that isnt assigned a port forward goes to the server, so if it were a case like that the speedstream should still be resetting too, or nothing at all should be.

I hope theres some kind of solution out there. i was thinking it was a log thing, and considering getting a linksys wrt54g, and a regular modem, but doesnt seem to be it, and that probably wont solve the problem, and just waste more money.

Also, added bit here, sometimes, the router doesnt fully reset. Just my desktop cant access the internet, the modem , or the router, but it can still access the LAN. Whereas all other computers have access the the net and lan, and just a little trouble connecting to the router when this happens. DHCP renewing doesnt help, rebooting doesnt help, only after forcing a reset of the router (di-524) does this revert back to a working state.
