RT-AC68U and Synology NAS Surveillance Package

I have been having ongoing issues with my RT-AC68U and the wireless performance on 2.4GHz. I have 8 Foscam security cameras (2.4GHz) and on this router most would randomly connect or not at all. Speedtest results on 2.4GHz were terrible, typically 1Mbps to 10Mbps on my 100Mbps WAN connection. 2.4Ghz devices would often drop off. 5GHz has never been a problem. I played with just about every router setting to try and improve the 2.4Ghz, I tried various firmware, Asus stock, Merlin and DD-WRT but to no avail. All my cameras are monitored and motion recorded by my Synology NAS which is attached to one of the router LAN ports. The NAS uses the Synology package "Surveillance Station" to achieve this. After trying everything on the router I then turned my attention to the NAS. I turned off Surveillance Station and immediately my 2.4GHz performance is back up. My cameras are all working as they should, Speedtest results are great again. For some reason this software on the Synology is bogging down my 2.4Ghz wireless. Has anyone had similar issues with Synology software or have any solutions as why this may be occurring?
 
When you use Synology with Surveillance stations they will constantly monitor the video for motion.
In your case all 8 cameras.
Suggest to try with fewer cameras and over wired instead to verify its the wireless for a start.
Also has the same setup worked with another wireless router before?

Which version Synology (HW and SW) are you running?
Does the stations have enough grunt to handle 8 concurrent streams including motion detection?

On the 2.4 GHz I would go for 20GHz only and turn off beam forming.

Regards
 
Hi,
I have only 3 camera licenses with Synology surveillance station. I run 3 cameras 24/7 and had no issues either with RT-N66U or now Netgear R7000. I only motion sense based recording on one outside camera. Maybe you should try adjusting motion sensing rate. Or you can try freeware iSpy to see if it makes any difference. BTW, my OS is W7 x64, i7 cpu with 16GB of memory

Tried fewer cameras, in fact just tried 2 cameras, same deal.

Yes, no issues with RT-N66U

It is a DS212+ DSM 4.3-3810

I have licences for all 8 cameras (not a cheap exercise!)
It works perfectly on my RT-N66U as well, so it is RT-AC68U specific.
I use VPN on my iPad using the Synology DS Cam app so I really want to stick with the Synology. When it works it works well.
 
Done that plus just about every setting and firmware available out there.

Tries turn off and on HW/NAT Acceleration?
Tried wired connection for cameras?
Tried QOS off?

QOS is off
Tried HW acceleration on and off
The only thing I haven't tried is wired connection.
But I have avoided that as where the cameras are would make
hard wiring them a very difficult job. The point is though that I don't
have these issues on my RT-N66U.

Hi did you try to change FW ?
Also check if it's switching channel , I see some problem in polluted area because the router change frequently is channel to try to find a free one.
BTW nice to know that the synology SVP is working OK I also plan to install few cameras next year on my 713
;)
 
I actually have the same problem. Here is my story (beware, quite long).

Setup
AC68U
Synology NAS
5 WIFI IP cams (working on 2.4ghz)

When the Synology NAS surveillance station is used it will continuously take the stream from every camera, look for motion and record or dispose it. So with and without motion the NAS is getting all the frames from every camera (by default 15fps per camera). The NAS is connected by wire to the AC68U.

Previously I had an old Linksys which supported wifi G only. It worked fine but when I went from 2 to 5 wifi camera the interface from the router went incredibly slow so I could not change port forwarding settings etc when all the camera's were on. However, the WIFI and camera's did work reasonable.

So since it was quite an old router I decided to upgrade to the best and fastest router available that I could find and went for the AC68U. And looking now at the router, it is a beast and works great! Some fine engineering! Unfortunately except for the problem with the WIFI IP cams...

When all 5 IP cams are connected to WIFI it will get incredibly (=unusable) slow. The signal is fine but the data transfer rate is unusable: loading an internet page could take 10 minutes. When I use a computer/laptop connected with a cable to the AC68U everything loads perfectly fast, so something seems to be happening to the wifi. As a reminder, this did not happen with the old linksys and all 5 cams connected.

After a lot of trying I changed the framerates from the camera's to 1fps so only 5 frames (5 cams) were traveling over wifi every second. And fortunately that worked.

But
One camera is located quite far from the router. It still has decent signal (better than with the previous linksys router) but sometimes - it seems randomly - during the day the WIFI again becomes incredibly slow and the synology nas says after a few minutes that it lost connection with that camera (it emails me automatically when that happens). After 5-30 minutes the camera comes back and the wifi works fine again...
So it seems like a bad signal from a wifi ipcam fills up the wifi spectrum. Again, this does not happen with the old linksys.

So at this moment everything works, but only temporary. Once or twice a day the bad reception camera disconnects and before and after that the internet is unusable through wifi.
Also, recording the IP cams at 1fps is also a temporary solution, of course I would like to record with at least 10fps or 15fps as with the old linksys.

Hopefully the information from above will help solving this problem since I really like the router and all the features it has!

Looking forward to a reply! Thanks.

More info
- The IP cams work on 2.4ghz as do the laptop, mobiles etc which also connect to the router
- Tried quite some different settings on the router as mentioned in this topic
- When I connect 1 or 2 camera's with cable I can increase the fps from the other camera a bit more before the wifi goes incredibly slow again. When a camera is connected by cable it works fine on 15fps and doesn't change the speeds on the network.
- There are no other networks that can be found with clients, neighbors are located quite far away so wifi crowding is not a problem.

Reading all this post I have the impression that the problem is a saturation of the band (2.4 Gz in the case) did you check the traffic monitor page on the router to see how much traffic is going on ?
