paulbates Posted January 18, 2017 Posted January 18, 2017 I went back through the write ups, a couple of questions: Would this represent your logical network, and specifically the cameras and the NVR are all on the same switch? wifi Internet Camera 1 ... Camera N NVR | | | | | Asus 87 Asus 68 | | | (AP Mode) (Router Mode) | | | | | | | | --------------------------------Cisco Switch------------------------------------------- Does just the 87 provide wifi, or do they both,,, and what channels on each if so? Do you use Adaptive QOS, if so how is that set up? Paul Paul
pcarfan Posted January 19, 2017 Author Posted January 19, 2017 Update Router is down again. I cannot access wifi with my iPads, yet I can view camera over LAN. Checked data load on the NVR, it is very high around 150 Mb/s. It stays the same even when I am not viewing the camera through LAN. So, something is causing the NVR to send out data at max bandwidth constantly. Could improper port forwarding or something going wrong with setting a static IP for NVR , cause this behavior. I doubt it very much as I can view the NVR via LAN even when I can't access LAN with any other device. But, I was asking because, when Q-see support remotely logged in to set up LAN/WAN for me, I know they went into the router interface to port forward and set a static IP. But, when I called Asus, they recommended setting it to factory setting, so we reset the router thus cancelling the port forwarding and static IP. However, even after the reset as I could access the NVR via LAN/WAN, I did not bother with it. I will be calling the excellent technical support at Q-see later today or tomorrow and will update. If anyone has any ideas in the mean time.

Do you use Adaptive QOS, if so how is that set up? Paul Paul Paul, that's not the setup. I only have one camera hooked up now, that and all future cameras will. E hard wired via CAT 6 solid cables directly to the NVR. Then NVR is connected to the router. The modem is hooked up to the wire that comes from the outside utility box. The router is connected to the modem. The Cisco switch is connected to the router. It doesn't matter whether I hook up the NVR to the router or switch, the sane thing happens. Q-See Seriously does have knowledgeable helpers. Hopefully they'll figure this out. I am glad, with all the help here, I was able to narrow it down as due to NVR outgoing bandwidth issue. This by the way happened even when I set the outgoing video quality to highest possible to lowest possible, when it malfunctions. In both settings it constantly sends out 159Mb/s of data whether any device us accessing it or not.
larryllix Posted January 19, 2017 Posted January 19, 2017 It should be noted that despite Gigabit ratings on each port, switches have a total backplane speed that the internal CPU can handle, and this may be only 1000 Mbit/sec also IOW: Gigabit may be for each post but the Gigabit/sec rating may also be the total for the switch shared between all ports, so that only one port can do that at a time. Another factor may be unless Ethernet ports are running in full duplex each Gigabit line is only capable of carrying 500 Mbit/sec of throughput. With full duplex, each Ethernet line is capable of up to 1000 Mbit/sec. but then the backplane of your router is now carrying 2000 Mbit/sec and may not like it. If any of this is the case, 2 cameras running 155 Mbit/sec with half-duplex and protocol overhead may be all you will ever get through most Gigabit switch/hub or Ethernet lines simultaneously.

It's just that, nothing else other than my ipad was accessing LAN at that time. This NVR shows bandwidth utility in real-time in a graph form. The outgoing signal was zero when it was working and ticks up only when I access it via LAN. Now the outgoing signal is constantly at around 150Mb/s. Doesn't this mean something else is going on also?

I was just PMing Paul about my router how I turned the signal down from 100 / 100% to 50 / 25% on 2.4 / 5GHz and the mass of errors, even on far WiFi devices, went away, overnight test only. I was also overheating my Netgear router causing it to crash. I guess the best thing would be to try to temporarily replace things and see trial and error style. (or car mechanic style) Not saying this out loud but... look for a store with a good return policy and open packages very carefully.
pcarfan Posted January 19, 2017 Author Posted January 19, 2017 Yeah! hoping it will be sorted out when I contact Q-see. He mentioned a firmware upgrade is probably all it needs. We'll see. Thanks!
pcarfan Posted January 19, 2017 Author Posted January 19, 2017 My Asus router has real time graph also. My goodness, YouTube video spikes it up, then I turned on Netflix and it jumps to megabit range. I knew I had Netflix, Hulu, YouTube and some others open all at the same time and my internet service and router never skipped a beat. 150mb/s cannot be crashing the router.

Yeah, one of the main reasons I don't have Netflix. Friends constantly hound me that I should get it but affording 3-4 GigaBytes per movie will cost me to upgrade my Internet service on top of things. Then I have to go searching for some movie instead of having push technology where I can sit and have them come to me. But then these services have improved my sat service so much we dont see the paying more for the same old... OTOH Netflix is beginning to take on it's own entity and more money for ISP speed, equipment to handle it and oher costs are coming....maybe. Meanwhile my denial friends are telling me Netflix doesn;t take that much with their iPads connected to their TV A/V jacks with a 1024 x 800 pixel screen with large black bars all around it. I just tested some Android Box TV being raved about and the scalped colour depth resolution and very low separation stereo sound is not worth it with a good 7.1 / 5.1 system. I am not going back to listening to some Transistor Radio quality sound again. Bandwidth is certainly becoming an issue and somebody is gonna' pay to build the system.

You have a link to the camera manufacturer? More importantly the actual ones/setup you have? Ill do a bit of looking.

pcarfan Posted January 20, 2017 Author Posted January 20, 2017 Yesterday the q-see guys installed something called 'Telnet fix" He remotely logged in, downloaded a file, did a bunch of things. Sort of like sending new data to the NVR. Not a firmware upgrade but sort of like a new packet involved. My NVR said it was processing something, rebooted. The scripts that was running on my computer said 'success' or something like that. He said that implied the 'Telnet fix" was successfully installed. Read9ng about telenet and security cameras. I see there were some hacking issues with these cameras with something called the root password being easily accessible. I don't know how hacking works, but I just installed my camera. But, it may have nothing to do with hacking. So, far so good. Will know for sure in 12 hrs. Router never worked for a 24 hr stretch after the cameras were installed.
paulbates Posted January 20, 2017 Posted January 20, 2017 Didn't see the other questions. The 87 is set up as a range extender only QOS is available in the router, it is disabled. QOS is a key feature of the asus for managing high volume traffic. I use the adaptive QOS with automatic bandwidth setting. I assign my devices a QOS level. While we don't have cameras, we do watch Netflix and Amazon Video at the same time. As an example, my kids were both home with phones, laptops and tablets over the 2 weeks Christma holiday. The echo, ISY, logitech harmony and roku TV get assigned as "highest" (red)... they don't have much traffic but don't want them impacted by lots of streaming. NAS, Roku, tablets. pcs, phones are all "high" (orange). The rest of IOT is medium (yellow). I use the "Customize" priority mode for tiering Video traffic first, web surfing second and gaming other last... we don't have any multiuser gaming... xbox puzzle type games. I would think about which one you want to win when the network is stressed? Netflix or NVR? I would guess netflix. So one thought is to use QOS tier the NVR below TVs, tablets, phones etc. See what that does. It different requires some trial and error. I would focus on the NVR as the focus of the congestion and not individual cameras. Assigning clients to a tier Tiering traffic type Evaluating how settings managed traffic I use the "MerlinWRT" firmware, but I believe these features are all part of stock, they are very close interface wise.

pcarfan Posted January 20, 2017 Author Posted January 20, 2017 It looks like the 'Telnet fix' has fixed the problem. So, it looks like it was some type of firmware issue. If bandwidth problems happen for real, I am intending to do some QOS management. For now I want to see what will assure a more safer security camera system not open to easy hacking. UPDATE: 'Telnet fix' the q-see support installed fixed the problem.
