Title: Router Hangs Frequently
Post by: Eluder on December 23, 2015, 07:57:58 PM
I've had a DIR-880L for quite some time now (1+ year) and I'd say for the past little while it has been quite unstable requiring a power cycle to get it going again.
I am running the latest stock firmware (1.05WW) and the trigger seems to be high data transfer that causes this router to hang (unresponsive to pings and connecting to the router via IP).

Basically if I am moving a lot of data to my NAS or sometimes even downloading at a high rate (I have a 250Mbps connection) the router will all of a sudden stop working and requires a power cycle.

This is quite frustrating and not the first time I've had issues with DLink so I'm really starting to be discouraged by the quality of DLink wireless products.

Can anyone advise what I can do to possibly rectify this issue?  Is it an impending complete hardware failure, or is it something else?

Thanks.

If your doing large file xfers a lot, I would highly recommend getting a external Gb LAN switch installed and place the switch after the router and connect the PC(s) and NAS to the switch. This will off load the large file bandwidth xfers and eliminate un-necessary router processing.

I'm in North America.
Ya, I know I've done a factory reset and setup the device all over again, just not sure at which firmware I may have done this.

I guess I'll do a reset now and see if it helps in any way.

I don't do a lot of big transfers, and by big, I'm talking maybe a 10GB file, which really isn't all that big, if the router is choking on that then I'd say it's a pretty weak router!

I will see if it keeps doing this, but if it does, I'll likely switch to another brand as I never had these types of issues using a certain blue and black router brand back in the day.

So this didn't happen before doing an update?
Would be interesting to see if reverting back to a older version to see if it happens.

What Mfr PC, OS version and Mfr and model NAS do you have?
So your doing 10Gb files? Are these single 10Gb files or multiple files equalling 10Gb?

Maybe I can help test this with you.

Well, I can tell you this, the Blue and Black company you reference isn't the same as in olden days since they were sold FYI.
Also know that doing any xfers thru any Mfr router will ot have as good performance as if you nstalled a Gb swtich and connected the PC and NAS to the switch.

Well I don't recall what triggered this, but it definitely didn't happen before, whether this was caused by an update or some hardware failure, I'm not sure.

I have a custom built PC, i7-2600k @ 4.5GHz watercooled w/16GB RAM, Samsung 850 pro, etc, this machine is more than powerful for the task at hand. :)
The NAS is a WD My Cloud 4TB gigabit.

Ya, sadly it's not the same company, which is why I won't be going with their routers either for my next unit.
I guess I'll see if I have a gigabit switch laying around, I know I have a spare switch, just forget what it is.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 24, 2015, 11:12:58 AM
Well lets see if I can reproduce this.
Let me know if your xfering a single file or multiples of 10Gb. I have a NAS that stores 10-30Gb files so I can do some testing with my 880L.

There are some known issues which I've made D-Link aware of and hope should be fixed after the holidays sometime. Probably next year.  ::)

Ya if you can connect a switch and test, let us know the results.
Title: Re: Router Hangs Frequently
Post by: Eluder on December 24, 2015, 11:14:38 AM
Single files that are ~10GB, not multiples, so it allows the router to pick up steam during the process.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 24, 2015, 11:18:07 AM
Ok, I think I have some single .mkv files on the NAS that are 15-20Gb. I"ll have a look and bring out the 880L and run some tests. I"d like to see if this is a problem and if so, get it to D-Link for review. I'm wondering if maybe the router is heating up during this process and stopping due to heat.

How is your router place? open area well ventilated? Or otherwise?

I recommend moving either that speaker or the router away from each other. Magnets and magnetic fields are not good for wifi signals. Is that a modem only modem?
Title: Re: Router Hangs Frequently
Post by: Eluder on December 24, 2015, 11:32:42 AM
They are computer speakers so I would believe they are shielded and also my issue is wired so doubt the speaker would be the cause.

It's a router and modem, but it is setup as a bridge.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 24, 2015, 11:35:24 AM
Ok. Well there is still some magnetic fields with even shielded speakers. Comes from the front thought limited.  ::)

Anyways, I'll have a go at this and see.
You don't remember what FW version you had on it before going to v1.05 do you>?
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 24, 2015, 11:36:52 AM
One test to try if you want and have time, disable both wifi radios and the run the xfer test. Still happens?
Title: Re: Router Hangs Frequently
Post by: Eluder on December 24, 2015, 11:39:25 AM
In terms of firmware I checked often so likely whatever was released before 1.05. I can temp disable Wi-Fi and see if it helps. The only thing is this issue isn't 100% repeatable, but it happens enough to be annoying.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 24, 2015, 11:42:13 AM
Ok.

Let me ask this, when you start the 10gb xfer, how soon does the xfer stop and you notice the router is hung up?
Title: Re: Router Hangs Frequently
Post by: Eluder on December 24, 2015, 12:03:22 PM
Can't give an answer to that to be honest, it just happens part way through it and varies.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 24, 2015, 12:11:56 PM
Ok, does it happen on WRITE or READ to NAS?

I'm setting up now for NAS, PC and router test now. WIreless disable for first testing.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 24, 2015, 12:24:55 PM
Im seeing 90Mb on the READ from NAS xfer. I did 1 17Gb file so far. Doing a 30Gb now.

Just PC wired to 880L. The router is't connected to any internet.

Will do WRITE next.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 24, 2015, 12:30:51 PM
OK, doing a 17Gb WRITE to NAS: 60Mb
Save for 30Gb file.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 24, 2015, 12:52:09 PM
Doing a 47Gb READ now: 90Mb
For the WRITE: 60Mb
Title: Re: Router Hangs Frequently
Post by: Eluder on December 24, 2015, 01:11:35 PM
Sorry for the delayed response, it happens on writes.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 24, 2015, 04:25:33 PM
OK, well I did both directions, didn't notice anything. The only thing I can try next is to turn on WiFi and connect the WAN port.  :-\
Title: Re: Router Hangs Frequently
Post by: Eluder on December 24, 2015, 07:01:19 PM
Appreciate all the testing. Let me know what you find but the most recent issue popped up while wifi was running to a iptv box and I was downloading at a high speed (35Mbytes/sec).
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 24, 2015, 07:29:09 PM
Ok, I'll turn on the radios and do more testing in the next couple of days.
What radio were you using while doing the xfer on wire?
Title: Re: Router Hangs Frequently
Post by: Eluder on December 24, 2015, 07:38:27 PM
I believe it was the 5ghz. The iptv box is connected to a dap I just forget which model right now.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 24, 2015, 07:41:21 PM
Hmm...so the IPTV box was streaming thru the DAP while you were WRITE to the NAS? I can test this configuration as well. I don't have a DAP anymore however I do have a couple of bridges. If you can get the model of the DAP when you can. Thanks.
Title: Re: Router Hangs Frequently
Post by: RYAT3 on December 24, 2015, 07:43:37 PM
Can you connect the NAS directly to the PC and write this file to it without issue?

Can you run a scandisk or chkdisk or something? 

(I don't have one of these so I don't know how it can be done, but I'd be curious as to the status of the NAS drive.)


---edit---

well I guess if the router is unresponsive probably not the NAS.. well, still worth a check with failed files written now...

I guess I'd put a fan on the router though...
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 24, 2015, 07:48:12 PM
Testing on mine today is working. However the wireless radios were disabled. I'll be testing with the radios enabled and if so, streaming something while WRITE to the NAS. Maybe he's hitting a over load on the router when using wireless and doing a WRITE to the NAS thru the router.  :-\

It's a dap-1513 that the iptv is connected to.

@ryat3, it's not the NAS as the entire router croaks when this happens. It's unresponsive to pings, my entire network is down at this time and I have to power cycle the router to get things up and running again.

Yup, iptv going, me writing to the NAS and probably even downloading from the same PC copying to the NAS from nntp.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 25, 2015, 10:23:25 AM
Ok I'll check this out in the next day or two.

I'd like for you to test a WRITE to the NAS when your not streaming with the IPTV and see if the router still hangs.

Merry Christmas.  ;)
Title: Re: Router Hangs Frequently
Post by: Eluder on December 25, 2015, 10:26:52 AM
I'm sure it has hung during a transfer to the NAS w/o the iptv going, but I'll see if I can repro it in the meantime.
I also have a gigabit switch lying around, so I could potentially offload the traffic from the router as well.

Merry Christmas to you as well.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 25, 2015, 10:33:15 AM
Let us know how it goes.

Have a great day.  ;)
Title: Re: Router Hangs Frequently
Post by: Eluder on December 29, 2015, 03:14:26 PM
So, I just had it die on me while downloading at 35MBps and transferring to my NAS, but my NAS and my PC are connected to a gigabit switch which is connected to the router.  This would offload the NAS transfer to the switch completely, correct?  Also, the iptv box was not in use at this time.
Seems like the fast download was enough to kill the router (had to power cycle it). I wonder if it's the number of connections I have open that is causing the router to hang, for nntp I've got 60 going right now to maximize my connection/speed.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 29, 2015, 03:33:20 PM
were you downloading something from the intenet while xfering to the NAS or was this download and xfer going in both directions to the NAS?

What MFr and model is this switch?

Ya the switch should be off loading the xfer between the NAS and PC. Do you see LED activity on the switch for the NAS and PC when your doing a xfer? The LED for the router on the switch should not be constantly ON while doing a xfer between the NAS and PC.
Title: Re: Router Hangs Frequently
Post by: Eluder on December 29, 2015, 03:37:24 PM
Download was from the net going to my PC HDD, transfer to NAS was from the same HDD to the NAS via the switch.
The switch is a Belkin 8 port gigabit switch, model F5D5141-8.

What LED on the router is active when transferring data? Is it on the back, because the ones on the front as solid and not flashing at all.
Switch LEDs are (heavily) active during the transfer.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 29, 2015, 03:40:20 PM
Ok so what happens if you do only a READ or WRITE to the NAS from the PC. I presume you don't see any router problems right?

LED on the Belkin switch that indicates the router connection. That LED should not be constantly ON while doing a xfer from PC to NAS. Yes it will be constantly ON while doing a download from the internet thru the router.

Title: Re: Router Hangs Frequently
Post by: Eluder on December 29, 2015, 03:42:52 PM
Well since switching to this setup, I haven't had a hang until just now during the heavy download, was during NAS transfers normally while utilizing the switch, no issues.

The LEDs on the belkin switch that were active were the ones for the two ports for the NAS and the PC.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on December 29, 2015, 03:46:56 PM
Ok. I'm thinking that if your doing heavy downloads from the Internet alone, that the router is the issue. I recommend getting on the phone with D-Link support and ask for an RMA. You can reference this thread if needed. Let us know how it goes.
Title: Re: Router Hangs Frequently

Well, looks like I'm done with DLink.
RMA was approved, however to do an advanced replacement, they want to charge me $8 to cross ship, if I choose the regular replacement, they don't charge me this fee.  Seems ridiculous as I've never experienced any vendor charging an administration fee to send me a replacement unit first that is under warranty.

That's just a really poor policy and treats customers quite badly if you ask me.

Thanks for the help Furry, guess I won't be returning to the DLink forums any longer.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on January 04, 2016, 09:51:23 AM
So why not do the regular fee. You still can get it replaced. If your still have a in store policy why not take it back to the store? You don't have a spare router to use while you wait to sent the 890L back? D-Link is honoring the warranty. I presume most other places maybe starting to charge for a cross shipping fee. Some places may not. Some places just ask for a CC number in case something happens or you keep both units. Cross shipping is a convenience and not apparent of the warranty. The warranty is being honored though. Not treating customers badly IMO.

Good Luck.
Title: Re: Router Hangs Frequently
Post by: Eluder on January 04, 2016, 09:55:37 AM
It's about the whole experience Furry, I'm well aware I can go through the standard replacement, but two things wrong here.
When I setup the RMA last week, the tech support rep said I wouldn't even have to ship the defective unit in, which I thought was great (logitech does this with their products), and now when I was told that was wrong, but I want the advanced replacement option, I have to pay an extra $*?  Again, it's all about customer service for me, product quality is the most important thing, but after that it's customer service and right now D-Link is proving that it lacks both to me.
I have another router handy for sure, I'm actually setting it up now, but my plan is to get my repaired or replaced DIR-880L back to sell it so I can use another brand going forward.
Title: Re: Router Hangs Frequently
Post by: FurryNutz on January 04, 2016, 10:05:24 AM
 Usually if you do a regular RMA, I believe you have to send your unit in and wait for a return unit to come in the main. Cross shipping would be that you keep the unit and wait for another unit to come in, then once you get it, and if all works out, you send the bad unit in. If they said something difference, we'll need to find out. Ok, I'll ask and see what the deal is. If I can help save you as a customer, will this work for you? I can't guarantee anything however I'll see what I can do.
Title: Re: Router Hangs Frequently
Post by: Eluder on January 04, 2016, 11:17:20 AM
That is the correct process for a regular RMA which is what I'm going to do at this point.
I don't need to go through the advanced RMA process as I have a spare (non D-Link AC router) which I'm already up and running on; I simply prefer the advanced replacement so I wouldn't have to tinker with my network much, but that's already been done.

I'm now just waiting on the new RMA approval to send in my bum router; when I receive the repaired router I'll be selling it to fund an AC3200 router from a different manufacturer.

It's up to you if you want to speak to D-Link Canada, but they weren't very accommodating when I spoke with them this morning. Had no real logic as to why they needed to charge me $8 to send me a replacement router first.

Thanks for listening...
Title: Re: Router Hangs Frequently
Post by: FurryNutz on January 04, 2016, 11:26:08 AM
Ok, Canada is different from USA. Sorry I can't be of more help. Sorry you had a bad experience. Please give the replacement router a try. Maybe you'll like it.
