Timer circuit to reset router

Feb 22, 2006 21 Replies

Hello,



I am trying to build a circuit which will turn off the power supply to my router once every now and then (e.g. I want to hard reset it once every 4 hours when I am not at home).



Any ideas where I should start? The more common timer circuits seems to need a trigger of some sort. Thanks!

X10 appliance module with a CP290 controller? You could throw in a phone answering thingy or a SMOP to control the CP290 over the Internet.

Are you trying to compensate for momentary blackouts/brownouts that cause the router to go bonkers?

What brand of router, so I can avoid ?:-)

How's it supposed to know when you're not home?

You could use a mechanical or electronic consumer timer and make a circuit that would interrupt the power for something like 10 seconds whenever it is powered up. Wall wart adapter, 7812 regulator, 555 timer, relay. Use the N.O. contact on the relay, and take appropriate care with the line voltage wiring.

Sucks big-time that the "designers" of such stuff don't put appropriate WDT and BOR/POR reset circuits and firmware in their products, doesn't it?

CD4060 counter, from memory, might do the trick, clock it, derived from the mains supply and select one of the outputs to pulse a mains relay.

But maybe a less error prone router would be better.

Get one of those perpetual bobbing bird toys and place it right over the power strip circuit breaker. Rub some pancake syrup on the bearings to slow it down to the rate you need.

well ... i threw that sentence in to make sure that no one will suggest : "why don't u go and reset it yourself"!

Yeah ... it takes hard reset to get the router back to life. I don't need fancy "controlled over the network" reset ... just something simple like "reset this thing once every 4 hours".

Thanks!

Just get a new router. Don't put a bandaid solution on garbage. They are SOOO cheap, check ebay.

Netgear are good. Not crazy about D-Link routers very cheap.

Of all the 'rubbish' I buy I often find the electronics quite good, but the software is hopeless. In particular the cheap chinese/taiwanese items. The idiots even swap "On" and "Off" in setup menus. Drives me nuts.

But, yesterday I bought a DVD/HDD video recorder from LG. I have not tried everything yet, but sofar it is brilliant. Excellent menus, well structured, easy to understand, does what it should do. Magnificent piece of engineering, and cheap too, at 250 euro.

I'm partial to the pre-Cisco Linksys stuff. It's pretty reliable even in poor power conditions. They don't like lightning strikes much though. ;-) Funny, the micro is usually still working inside, but the network ports die.

The Linksys Pre-Cisco stuff was pretty good, now it's who knows. Wonder what happened?

Are you sure it's the router? Around here it's usually the cable modem that gets hosed.

I have an SMC Barricade (8X) router that occasionally loses track, particularly when Cox loses it then comes back on-line... maybe once every month or so.

An SMC Barricade router, wow I had one of those ages ago. It would lock up once in awhile too. That is an very old router, look for new firmware that may help. Also ebay a new router!!! They are so cheap and most work.

I'm certainly not going to buy new, if this only happens every few months.

I finally had to retire my original Linksys BEFSR11 router. It was locking up every 15 minutes. On the other hand, I did use it for almost five years before it went flaky. I replaced it with a Linksys WRT54G.

I tested a Belkin F5D7230-4, but it was crap. It would not only lock up but it reduced my bandwidth from 3 Mbps to around 300 Kbps, even on the hard wired ports. The wireless signal was unreliable, as well.

I was under the impression it happed every 4 hrs, only point I was trying to make is the cost & time involved would cost more than an ebay router.

These menus are usually designed by software engineers. Nobody likes to do user interfaces, so the guys right out of school get the job. Sometimes the guy out of school has a clue, or they actually do some user testing before release. You got lucky. Most of the ones I've seen recently are crap.

Seems that many of these share the same hardware and base software. The ethernet can/will hang. Whether it is software or hardware, I don't know.
