Good Morning!
I am finding myself regretting this purchase a little bit, as it is now just over a year past when I bought it, and this has started.
During usage, random reboots occur. THis is just a reboot of the router itself. The modem never reboots or drops a signal. Pretty straight forward problem. I have the following
~25 wireless devices (mixed between 2.4 and 5gh)
~5 wired devices
The 809L is on Firmware 1.08, hardware version A1, region is North America (washington state) ISP is Comcast. I tried upgrading to the latest available firmware (1.09 B14) and had the same problems, so I went back to what it was on.
Attached please find a sample of my syslog:
07-11-2016 21:28:45 Local7.Debug 192.168.101.1 DHCP: Server sending NAK to 54:e4:3a:99:f7:8f.

I can get a more detailed syslog if need be. Im hoping someone may have an idea on where to start with this.
Thanks!

One reason for reboots maybe wireless interferences:

Furry,
Thanks for the quick response. No a factory reset has not been done. Would that be your next course of action?
My modem is not provided by the ISP, but one I purchased. It is a Motorola ARRIS Surfboard SB6183.
Wireless modes are b/g/n mixed with wpa2 for the 2.4ghz, and a/n/ac for the 5.0ghz.
No other wifi routers in the building. Closest is about 2 doors down from my apartment.
Smart Connect has been disabled for a long time now.
-
Have you been able to calculate when these random reboots happen?
Yes I would do a factory reset and set up from scratch. Please set the router with SmartConnect enabled this time.
-
Furry,
No, I haven't been able to narrow down when they happen. I'll do a factory reset right now and set it up with Smart Connect enabled.
I'll report back.
Thanks
-
Well as I was writing a response, the router decided to restart randomly (again) so I took the opportunity to reset it completely, and rebuild it with the Smart Connect turned on.
I re-enabled logging, and am putting it back through its paces. Will report back if it happens again.
Thanks
-
Ok, Keep us posted.

After complete reset with specified settings, it worked for a while. Here is a current log from the last restart just a minute ago:

Are you using a different IP address pool or default? I see 192.168.101.1 and .###
-
Yes I changed the default to 192.168.101.1
-
Would you mind doing a factory reset and then use the default IP address pool and lets try using 1 wired PC for now and turn OFF ALL other devices fully.
I'd like to see if the router still reboots with just 1 wired PC connected. Then lets try adding 1 wireless device.
What all do you have in devices that's connected to the router?
What browser did you use to upgrade the FW and manage the router?
-
I can do that, sure.
I have 12 windows tablets, 10 cell phones, a domain controller (hardwired), my main machine (hardwired), 2 laptops (wifi), 2 laptops hardwired, a ps4 wifi, 4ktv wifi, roku wifi, chromecast wifi and my wifes laptop and cell phone both on wifi but not here at the moment.
Whats weird about this, is that I used to have a couple of virtual hosts as well, running about 40 hardwired virtual machines, and the router handled everything without issue. Hell, my current setup was being handled without issue until a week or so ago...Im wondering if there is some hardware failure in the device...
Ill go ahead and shut down everything except for my main machine (hardwired) and my domain controller (hardwired) and do a full reset of the router again.
I use Chrome to manage the router, and have used it to upgrade/downgrade the FW.
-
Wow. That's alot of wifi devices...wifi 30 devices :o
All these are at home?
How many online at the same time?
Possible that you maybe hitting a max connection/device limit on this home class router. Not sure quite yet though. Starting with 1 wired PC for now and then adding 1 wireless I'm hoping will see a change in behavior.
-
Yeah its a few devices for sure. Yeah all of these are at home. They stream flash videos and advertisements 24/7. I usually put about 13tb of data through the router per month.
I'd be super frustrated if there was a device limit on this router, as that was one of the motivating factors/justifications for spending $300 on a consumer class router. Also, for it to start happening now as opposed to when I have had it even more loaded, is just...Odd.
Im spinning everything down right now in preparation of a reset. Have to let all my production stuff wind down.
-
Ok, this helps explain more of your situation. The problem being 1, you have a lot of physical wifi devices, 2, there all connecting at the same time and probably maxing out the limits of the router, 3 each device is streaming bandwidth and data connections which is probably also maxing out the bandwidth connections limits on this router. This is a factor in any wifi configuration and home class router. We see this with business class configurations, like at a hotel? They have one or maybe two routers, however many wireless access points to cover range and quantity of devices connected and bandwidth. This helps spread the connections and bandwidth needs over the many APs. The bandwidth connections is not just 1 per device or applications, it ranges from few to many per device and application. Browsers can have hundreds going thru the router on just one PC. Now your combining 29 other devices doing other things, ya, your probably going to be hammering there router and thus maybe a reason for the reboots. This would effect any home class router. ::)
I'm hoping that using 1 PC and 1 wireless device for a short duration test will see a change in this behavior.
-
Yeah thats understandable. There are easily thousands of independent connections. Again tho, it is weird that it used to work just fine with even more. In a case like this, I would think that instead of failing and rebooting all together, it would at least drop some connections, or have some packet loss or something other than basically die, ya know?
I can almost promise that using a single wired and single wifi device, itll work just fine, but thats not really a solution ya know?
So can we play devils advocate for a minute? Lets assume that 1 wired deivce and 1 wireless device makes everything hunkydory. What are my next steps? Am I just going to be limited by this router even though I wasnt before? Is the hardware just going bad and thus not able to handle a heavy work load anymore?
Not trying to be rude, and I appreciate your quick responses to my questions, i'm just curious what my next step would be after this test...Or is it just kind of a futile test to tell us something that doesnt help all that much?
EDIT: I should mention that I bought this device (according to my Amazon order) on September 10th 2015. So it isnt even a year old.
-
Ya, may have been working before or may have been a certain situation when you had all of your devices connect. Still to early to tell.
Not being rude. Questions are recommended always. ::)
Next step is to graduate adding devices, 1 at a time and try to see when and if the problem appears. Take notice of what was connected and what you were doing with the devices or other devices while you were adding devices when the router reboots.
Possible that this maybe a wifi issue and that many wifi connections maybe a cause. I only know of one other user on this forum with this router and he has maybe a few less wifi devices however hasn't said anything to me about any problems with reboots with this. I'll have him review this and add any information to this thread that maybe of help.
-
Okay cool. Thanks for your patience.
I had everything powered off, and just as a quick preliminary test, I powered up the 12 windows tablets and started to get them running. Router restarted almost right away. So there is definitely something wrong with the wifi, and it doesnt appear to be device numbered. I had all of the cell phones off for this.
I'll continue with the test as you have requested, and will keep you posted. But having the router restart with only 12 wifi devices running for 30 seconds doesnt bode well.
-
Ok, one more thing to do after testing,
Lets do a full manual installation of v1.09 FW using this process to install it:
Emergency Recovery Mode (http://forums.dlink.com/index.php?topic=44909.msg163599#msg163599)
Use IE11 or FF for this..and disable any PC security SW and security browser Add-ons.
-
Okay. I've done as suggested. Ive upgraded the routers firmware using the recovery mode, and started with a single hardwired device. That was fine. I added a wifi device, and it was fine.
Was. For about an hour. One wifi device and one hardwired device, and the router restarted itself.
So its obviousa this thing is busted. What is my next course of action here, because this is damn unacceptable from a $300 router. This is unacceptable from a $20 router.
Im beyond pissed off right now.
-
Its happend 3 more times today.
I have removed the dlink router from my network, and replaced it with a $30 god damn dollar ASUS router which has been rock solid.
What the hell? Honestly, Im so beyond pissed off right now. I spent $289.99 on a route rthat touted a LOT of stuff, and has provided none of it, and a crappy interface to boot.
I need a god damned syslog server set up on my computer just to see what the hell is going on with it? Seriously? What the Eff.
THis needs to be corrected. THis needs to be addressed. THis crap cannot stand.
I want my money back from this router.
-
Seriously? *cr*appy* is censored on this site?
-
Ok, I was hoping that a full on FW re-load might have fixed this however I think the unit is just faulty. D-Link will be happy to get it replaced under there RMA service. I recommend that you phone contact your regional D-Link support office and ask for help and information regarding this. We find that phone contact has better immediate results over using email.
This issue is not reflecting on the entire 890L line as others have not experienced this issue. I for one and another I personally know are enjoying this router and it does work well. Sorry that you got bad apple. I know that D-Link will get you a good working on soon as you get the phone RMA process started.
Let us know how it goes please.
-
Were you able to get a hold of D-Link support and ask for an RMA? ???
-
Yes sorry, I just sent the router out today. I had to call them and go through a bit of 'troubleshooting' in which I told them I worked with you and they essentially said "that guy doesnt work for us/cant say anything"
So that was weird. Also it sucks that you have to pay for it to be shipped back, but im optimistic.
-
Ya we are volunteers here in the forums. ::)
Most any Mfr now days has a one way shipping policy. Been like this for years.
Keep us posted on the new one. Should work well. What router are you currently using now?
-
Gotcha, gotcha.
Right now Im using a $30 router that I picked up from frys the other night. I've got over 30 devices connected to it, and they all run well, until my wife starts streaming a 4k movie from netflix. Ugh.
That being said, the $30 asus router management console...INSANELY NICE. It is quite a nice change of pace from my dir-890L's
fisher price my first router" interface.
Just the ability to see real time logs, real time utilization (both wired, wireless, and internal router spec utilization) is awesome. And on a $30 router, lol. Im more frustrated now because it was originally going to be this DLINK or one of the $300 ASUS routers.
Not the first choice that Ive regretted, wont be the last.
Friggin technology.
-
Ya, the UI seems simplified from the old ui. Some users have expressed there dislike for it. I presume D-Link went with a setup and and forget it kind of line of thinking in regards to it. Kind of makes sense to some degree. I guess there;s a fine balance between not having enough and too much that some advanced users like.
You could hook up the replacement 890L as a wired AP to the Asus router. ::)
I hope the replacement work well. Does for me. ;)
