Title: DIR-632 disappears regularly, requires reboot
Post by: gauss256 on April 21, 2011, 11:00:18 PM
I've just been using my DIR-632 for a couple of days but I've had to reboot it several times already.  I have a couple of laptops and mobile phones connected as wireless clients, then after a few hours, suddenly the router is no longer available.  Its SSID doesn't show up and all connections are dropped.  I have to power cycle it to bring it back to life.

It is in the same location and environment as another older router it replaced which didn't have problems like this.  There are no wireless phones or other obvious interfering factors.

How can I fix this?

What is your ISP service? DSL or Cable?
What is your ISP Modem? Stand alone mode or built in router?
What wireless modes are you using? Mixed? Try single mode G or Mixed G and N?
Try turning off auto channel scan? Try different Channels, start with 11 and work your way down.
Any other WiFi in the area?
Does this happen with only one device connected and all others turned OFF?
Any cordless house phones in the area?

Great checklist!  Here's our situation:

ISP service: Cable
ISP modem: stand alone, but there is a router in between the modem and the DIR-632.  I set it up following the procedure to "Connect to Another Router" in the manual.
Modes: It was mixed b, g and n.  I have now set it to mixed g and n.
Auto channel scan: Was on, I have now turned it off and set to channel 11.
Any other wifi: We're in a residential subdivision, so there are several other wifi setups in neighboring houses, but nothing closer than that.
Connected devices: We generally have at least two or three devices connected at once.
Cordless phones: There are a couple of Panasonic 5.8GHz phones in the house.

I'll let you know if it's more stable after the changes.  Thanks!

Ok, I recommend going from Modem to DIR router.
Whats this other router?
Title: Re: DIR-632 disappears regularly, requires reboot

The other router is an old Linksys WRTG54 with its wireless turned off.  It gets worse: there's a switch in there too, so the chain is:
cable modem => router => switch => DIR-632

That's a little messy but it puts the DIR-632 in a location that's good and gives me the network connections I need for wired devices near the modem.  I plan to replace the router+switch pair with a more modern 8-port router to simplify things.

After the first changes you suggested things have been stable.  But if the problem recurs, I'll try hooking up the DIR-632 directly to the modem and see if that works better.

Thanks again for all your help.

It failed twice again today.  So I changed the network topology to:

cable modem => DIR-632 => switch

I'm using the DIR-632 as a router now and have one less item in the chain than before.  It's in a different room now too, so maybe a different environment will help.

Here's hoping...

It failed again.   ???

I've now switched to Channel 6, but I'm not very optimistic.

This used to happen about once every two weeks with my old Linksys router.  With the D-Link the mean time between failure is about 12 hours.  Maybe my cable modem is doing something to mess up the wireless router??

And ... channel 6 failed too.  I now have a case number with D-Link Technical Support.  They took me through many of the same questions and steps that were suggested here, then we reset the router and re-configured it from scratch.  It failed again after a few hours.

Is there some sort of logging facility that can be turned on to diagnose problems like this?

Can look under Tools/Logs and see if there are any entries for this time frame that your seeing this reboot. And you are using Single mode G to test?
Try changing form auto bandwidth to 20 only.
Try turning off Short GI under Advanced/Advanced Wireless.
Test with only one wireless devices if you can. Graduate turning on other devices.

Let us know.

Check Status/Logs

What was the device you had connected when it failed?

I also have this problem.  I talked to tech support and they recommended that I return the router.  I am curious if anyone else has an Android phone that they use on their wireless router?  I read a story about Android phones causing problems with DHCP on a university campus and that university no longer allowing Android phones on the network.

Possible, have seen some interesting issues with cell phones and routers.
Did you try changing the wireless modes?

I just did this morning...to g only.  I will monitor it for a day and see what happens.

Keep us posted.

What is your ISP Service? Cable or DSL?
What ISP modem do you have? Stand alone modem or built in router?

Located in Idaho?

The logs don't go back as far as the failure. Maybe they got wiped when I rebooted

At first I thought no device, but I might have had an Android phone on it.  I see another message about Android causing problems.  It is a new phone (Nexus S) and the wifi on the phone side is a bit iffy.  That was one of the reasons I updated my router and network.

I've already made some changes that I'm testing.  I'll monitor things before doing anything else.  If it fails again, I will take the Android phone off the network but leave everything else the same and see if that makes a difference.

OK,
Can you try a different WiFi Device, something non cell phone? Laptop or WiFi desktop something along those lines?

I just submitted a post because I am certain the DIR-615 is crashing when I connect my Motorola Xoom, running Android.
Does Motorola Xoom crash the DIR-615?
http://forums.dlink.com/index.php?topic=38313.0

I would say that if you have an Android device that is crashing your router, and I have an Android device that is crashing my router, then one more and it is a confirmed problem!

After much help from this forum and three unproductive calls to D-Link support ... I gave up and bought a Linksys router.  Seems to be working fine, with an Android phone, an iPhone, an iPad, a Windows box and a Mac.  Doesn't have 8 ports though.   :(

I just purchased a DIR-632 and am having similar issues - the router crashing about 1-2x per day; all lights stay on, wifi shuts off and ethernet stays L2 connected but drops the IP address.

I seem to be able to triggers this behavior by running a session of logmein on one of the attached computers.  I'm running the latest firmware (just upgraded) and the router is attached to a corporate network (we're just running a local subnet) - its likely 1-2 firewalls away from the public network.

Any ideas?  Otherwise I'm going to have to take it back to the retailer.

Thx.

If you have lots of other WiFi in the are, could be a reason why the router is stopping or need rebooting, it cant find a open channel and maintain signal.

Also for future reference, please post in the 635 forum as it is closest in features for your 632 router.
Thank you.

Didn't fix it.  Three strikes and its out - back to the retailer; got a Linksys router that I've had good luck at home with.
