Title: 880L Crashes and Reboots When Connecting to 5GHz With QOS Enabled
Post by: square_eyes on January 12, 2015, 07:34:10 PM
Edit: Amazingly, whilst on the phone to support, during the long waits I started rehashing some of my troubleshooting. I discovered that disabling QOS allowed me to get on to 5GHz. I am certain I had tried all my previous tests in isolation. But now I'm able to get on (for at least 30 minutes so far), with a static IP for the 880L. So I have to say at this point that this is a QOS issue, only made apparent when my Macbook Pro connects to 5GHz.
----

Fatal, repeatable DIR-880L bug for me.

FW:1.02, HW: A1, Macbook Pro Retina 2014, OSX 10.10.1, Huawei Spark HG630b Modem

Repeatable bug: After a factory reset, and no other router config, adding a device to one of the QOS options (saving and rebooting), results in my Macbook pro causing a fatal router crash when it tries to connect on 5GHz. The router continues to crash and reboot as long as the MBP is trying to connect on 5GHz. Switching to 2.4GHz restores peace in the world. I have tested a couple of other 5GHz devices and they don't have the same issue.

Previous post...


Background:
My modem does not "support" bridge mode, and I need the D-Link to handle port forwarding. As such I have been asked to keep the modem on a separate subnet and turn off DCHP and WiFi. This is actually what Huawei calls bridge mode when you call support. In spite of me telling them that it's not truly bridge mode, the morons just keep sending me the same copy paste email instructions. Over and over. A smart user on Stack Exchange suggested using DMZ to forward inbound connections to the 880L. This works fine! But the 880L needs to have a static IP. When I set one up as described above (outside the modem's DHCP range) inbound connections are correctly sent to the 880L, which then handles the port forwarding. There's one problem, connecting via 5GHz from my laptop crashes the modem. Staying on 2.4, everything works as it should. Setting the connection to DHCP means I can't have a static IP. Stupid Huawei doesn't have address reservation either. I found this bug out through extensive trial and error, starting from a factory reset and configuring one option a day to see what broke the router.

Other notes:

Internet Service Provider and Modem Configurations

You may want to check with your ISP to see if they support using a stand alone modem. It's highly recommended to use a stand alone modem with external routers such as the DIR-880L

I've been using my Mac Book Pro 2007 with OSX 10.10.1 and haven't seen any issues on either radio...

The reset or rebooting of the router is a symptom of the router either mis-configured or some form of interference....

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.
Let us know how it goes please.

Did that. Got told their servers are down and they can't help me at the moment. Funny too, the first 3-4 times I called Huawei to get "bridging" instructions I got told the same thing of their servers.

The guys that invented telephone networks, and ensured near on 99.9% up-time would be rolling in their graves if they saw today's enterprise networking service-level. Let alone our pokey, over priced, consumer grade routers and switches ;D ;D ;D

I'll be sure to report any progress.

Please see my edit on the first post. I stumbled on finding the real root cause, QOS, rehashing some troubleshooting steps while on hold at the D-link call centre.

To my amazement, when I explained this to the L1 tech he had the audacity to ask me what the problem was then, and why don't I just disable QOS.

Makes my blood boil. Is it not unreasonable that a feature on the side of the box, one of the main reasons that I purchased the unit for, works correctly as advertised? Not that it's any of their business, but I run an audio networking service that requires high availability, I want it to have the highest priority of all of my traffic, in a busy household.

Note that this is after several factory resets. And I notice there is another post about this (http://forums.dlink.com/index.php?topic=61613.msg248110#msg248110) so I'm guessing it's a firmware issue. I'm waiting for a L2 to call back in 24 hrs. But as they never called me back the first time, I'm not holding my breath.

This maybe a faulty router or a problem with the Apple LT.

So far I've been using the 880L and haven't seen any issues with the latest FW and on OSX 10.10.1 using my LT however your HW is newer than mine so could be the difference.

Do other 5Ghz devices work with the router? I'll put my Mac Book Pro in the QoS and see what happens. Normally the only devices I put there is my 2 game consoles.

My Galaxy S5 has no issue connecting on 5GHz with QOS enabled. And my MBP as no issue (after 24hrs) with QOS disabled. I have spoken to L2 of both manufacturers, with varying degrees of helpfulness, who both suggest it's the other's fault.

Likely not relevant, but I'll put it here. I'm also having an issue with my MBP where hot swapping USB 2 devices locks up all USB input (https://discussions.apple.com/thread/6697395) (including the built in keyboad and trackpad). Just in case there is a link.

Any chance you can test out a different MBP? If your seeing other issues with your MBP, could be an issue with the MBP itself. Testing of another could help confirm either way...

QoS is meant for two ir more devices. Also if you have a VoIP device like Ooma, remove it from QoS and place it in the DMZ. Most VoIP devices dont need to be on QoS and work better in the DMZ.

I have roughly 20 devices on the network, but really the Ooma is the only one I need prioritized.  Do I need to hard code the IP for that device when I assign it to the DMZ?  It's behind a switch (not plugged directly into router)?  And would it have to be plugged directly into the router or can it be plugged into a switch?

Yes, give a Reserved IP address for the Ooma and set it into the DMZ. No you don't need to connect it directly to the router.

Thanks for support.  Took 4 steps to (hopefully) resolve my reboot issues:
1.  Replaced my cable modem (SB6141) with a Zoom 5341J:  Users from Comcast forums state the 5341J is very stable. 
2.  Upgraded firmware to 1.02 B13. 
3.  Reserved IP address for Ooma under connected clients
4.  Enabled DMZ mapping to Ooma reserved IP address

I've also set the system logs to write out to my mac file server (which also has a reserved IP address). 

So far no reboots (with 20 connected clients, wireless and wired), and I've got a pretty sophisticated monitoring system (3 kids that are constantly connected to the internet).

Sorry, I wasn't being notified of these posts. I gave up. Contacted D-Link call centre many times and L1/L2 just fumble around uselessly. I get told they have to escalate it to level nth and nobody ever calls back. Rinse and repeat. All relevant info is in this thread already I think.

My MBP works fine on AC5ghz, as does my Galaxy S5. Then I implement QOS for any device (I want a Windows PC to have priority). I boot up my MBP, it tries to connect, then we get a crash/boot cycle on the router.

Ok lets try this, download the last FW update from the web site and unpack the zip file.
Use IE or FF only, and disable any 3rd party browser add-ons and disable security SW on the PC.
Disconnect all devices accept the wired PC. Including the ISP modem. Will connect the ISP modem later. Just test with out it for now.
Factory reset the router using the UI or the button.
Reload  the FW file.
Factory reset once more after the FW was processed.
Set up the router from scratch.
Set single mode N on both radios and give separate SSID names for each radio.
Set Open security on WiFi temporarily. Will enable WPA2 later.
Set up a reserved IP address for the wired PC.
Turn on the MBP and see if it connects. If so, give a reserved IP address and save settings.
Reboot the router with the PC.
Place the MBP into QoS at a high or low section.
Place the PC into the high or highest section.

Anything happen using this process up to this point?
If the problem still happens here then I'm thinking the router needs to be RMAd.

Let us know...

MacBook Air mid 2014 os x 10.10 - the same QoS issue with the 1.02b13 firmware. Didn't had time to tried with 1.03 from ftp.link.ru because that new firmware have a bug regarding guest mode wifi and I need it. PPPoE connection, 1 gigabit speed download, 100 megabit speed upload. Another issue that I found is with vpn, I cannot see the lan or the router (ping request timeout). I can access vpn only to obtain the router ip.

I've never seen QoS work... ever. Not on my old Netgears, Not on this D-Link, not on my employers enterprise grade WAN optimiser. It's a made-up fallacy used to sell hardware, just like self cleaning ovens. It doesn't actually work, but people wouldn't buy it otherwise. It should be illegal to advertise a feature that doesn't do what it's supposed to do.

I was wondering about that actually.. It sounds amazing on paper but i cant say i have ever noticed a difference with QoS. My internet doesn't ever get more than 1Mbit upload so the moment anyone starts uploading anything from a photo to a video the internet becomes useless for the duration of the upload. If you're in a call it's done, if you're on a game it's 500-1000ms ping etc. Thought QoS would be a life saver but really i just wish i could limit the raw upload speed of any device to no more than 0.5Mbit as the QoS wasn't helping..

I run an online radio station. All I want is the traffic on one port, from a particular local IP, egress, to be stable. It's only a source client, (I have a well endowed distro server upstream) so it only requires a steady 128kbs on a 3mb up link. But no.

What FW version do you have loaded currently?

QoS has been working for me and works well aside the enabling and operation of it on prior FW versions.
