Network Log Critical Errors - Hub 3

Hi, I have a Canary security camera, that keeps going offline, the hub says it is a weak wifi signal, but it is only 6 feet away in the same room. My question is i seem to have a lot of Network errors each day some critical, could this affect my camera going offline then back online, sometimes within a minute, and at other times over half an hour. I have had the company check it out, and they say that it is going off numerous times each day. Can someone please give me an answer. I have separated the 2.4Ghz and the 5Ghz, as the camera only works on 2.4Ghz, with passwords etc. This has been going on for a long time. I have tried your technical support, but no disrespect, they do no have the experience to answer my question, and want to pass me over to appliance support, which is very unhelpful.

There has been a lot of activity in the green cabinet lately, but they wont say what is going on, just that they are sorting out the Network, surely these errors should not be there, but why are they not been picked up, my router picks them up so why do Virginmedia not get a report. Sorry for going on, but i just want to know why the camera keeps going offline, looking for any answers.

Many Thanks

Re: Network Log Critical Errors - Hub 3

Hi there Bazzamer, 

 

Thanks for your post - sorry to understand that you're having some issues with your security camera. 

 

Are you having any issues with any other devices connected to the Hub or is it just with the security camera? 

 

Cheers

Re: Network Log Critical Errors - Hub 3

Hi, Many thanks for the reply, and trying to help in this problem.

I am having no other problems, but if the camera is sending information to the camera server, and goes offline, could the network be the cause of the problem, as a critical error means something. The Canary people say it is going offline a great number of times during the day, thanks for the help.

Re: Network Log Critical Errors - Hub 3

The first thing to check, would be if the internet connection between the Hub and VM's servers.
Do devices connected directly to the Hub drop the same time, or do the Hub's lights change behaviour?

Posting the Hub's metrics may help to see if the log entries show anything.
Navigate to the hub's GUI using http://192.168.100.1
Don't log in, click the Router Status button in the top right of the screen.
Copy \ Paste the Downstream, Upstream, and Network Logs.
Don't worry about the formatting, but do obscure personal information like your WAN IP address.

The wireless connection between the Camera and the Hub maybe dropping.
This is the most likely cause as the 2.4GHz band is narrow and popular with many devices using it, not just neighbouring wireless networks but domestic appliances like A\V Streaming Devices, Baby Monitors, older Cordless Phones, Fluorescent Lighting, Hearing Aids, Microwave Ovens, Plasma TVs, security Systems, Zigbee etc. etc. The devices just need to be in range to disrupt your signal.

I would download a wireless scanner like InSSIDer, or WiFi Analyser for Android, which will show you the wireless networks in range and what  channels they are broadcasting on, bearing in mind it will not show interference from domestic appliances like I mentioned above.
The scanner's timegraph should show if the wireless connection is dropping.
You can use the scanner to select the best wireless channel to use at the time, or confirm that the hub's channel optimisation is using the best channel, if you have it enabled on the Hub, personally, I would disable it at set the channel manually.

Another possibility is that a hacker is knocking the camera off the wireless network with a deauth attack which is pretty easy to do if the camera doesn't support 802.11w.

The last two points suggest that wireless isn't the best medium for security cameras.

You alway have the possibility of Hardware or driver issues to throw in the mix.

Re: Network Log Critical Errors - Hub 3

Hi, Before i go and check all the things quoted. Most of my things are on 5GHz, and will stay on it, as i have stopped them defaulting to 2.4GHz, the camera is on 2.4 and cant default to 5, but i just checked its speed and it is only 57.12, it is on channel 13/24 which is set to automatic. The camera is only 6 feet away, which i think should have a faster speed than this, Network log is.

14-5-19 11.24am Critical Sync Timing Syncro Failure: loss if sync: CM-MAC = **:**:**:**:**:**; CMTS-MAC = **:**:**:**:**:**: CM-QOS CM-Ver-3

11.24 Warning RCS Partial service CM-MAC = **:**:**:**:**:**

11.24 Warning Lost MDD Timeout: CM-MAC = **:**:**:**:**:**

11.26 Critical Received response to broadcast maintenance request but no unicast maintainance opportunities received T4 timeout - CM-MAC =**:**:**:**:**:**

11.26 Critical no ranging response received T3 Timeout CM-MAC = **:**:**:**:**:**

hope this helps, back to reading suggestions.

many thanks

Re: Network Log Critical Errors - Hub 3

The channel 13/24 doesn't make much sense unless it means CH13 on the 2.4GHz band. (the \24 notation usually defines a subnet)

I would bear in mind that CH 13 is an overlapping channel and any network in range using the non overlapping channel 11 will be interfering with your signal, so I am a bit surprise that it is automatic selection on the Hub.

The camera's speed will depend on how many antennae the camera has, if you are using channel bonding (2 wireless channels) and how the speed is being reported.(if it is an actual speed from a speed test site or a reported Link speed)

A wireless channel on the 2.4GHz band has a LINK speed of 72Mbps (real world speed of around 40Mbps).
Bonding two 20MHz channels to form a 40MHz channel can double the speed, but in the real world, speeds are often reduced as the 40MHz channel width effectively hogs 2/3rds of the 2.4GHz making it prone to interference.
The Hub 3 should drop the width down to 20MHz if it senses interference.

MIMO devices can double the speed by transmitting two stream simultaneously, doubling the speed.
In reality, 57Mmps is a fairly respectable speed on the 2.4GHz band and is more than enough for your camera's needs.

The logs are showing a local circuit dropout, but without the logs and power levels in full, it is impossible to say if this is just a blip or a more consistent local circuit issue.

I would bear in mind that you could have two problems, the local circuit dropping and the wireless connection dropping as well, but it would be wise to resolve any local circuit problems before delving into the wireless side.

Re: Network Log Critical Errors - Hub 3

Hi, Been a bit of a problem trying to get the info, had to find windows machine but cant get 192.168.100.1, Found a way to do it,  I have saved Downstream, Upstream, as I normally work off an Ipad pro. The 13 / 24 is channel 13 of 24 channels i presume.

Well the only one i could get to work was Insidder Home, apparently my 2.4GHz is on channel 1, and my 5GHz is on channel 44, but the Mac address in the router do not agree, in the errors it says one number and in the insidder the end one is 4 different, maybe thats why the errors are possibly produced. I have pasted the upstream and downstream below, hope it helps.

Re: Network Log Critical Errors - Hub 3

Hi, These are the things you wanted, had all sorts of probs, as normally use ipad. Downloaded Insidder Home, and found that my 2.4GHz is on channel 1, and the 5GHz is on channel 44. One last thing that i noted in the errors, the mac address is different by 4 digits in the Insidder so could this be the problem, I did not input the addresses in the router. Its all a little beyond me but have worked it out a bit, if you need anymore info please let me know.

The help is really appreciated, many thanks

Re: Network Log Critical Errors - Hub 3

Sorry. my bad on the Hub address, I forgot to amend my macro for the Hub 3 which doesn't like the 192.168.100.1 address in router mode, it usually only responds on 192.168.0.1.

I wonder if the iPad Pro is reporting a IP address of 192.168.0.13/24 which would make sense. There are only 13 channels on the 2.4 GHz band.

Each of the hub's wireless radios has it's own MAC address (Separate networks), so maybe that is what you are seeing.
I would monitor the 2.4GHz channel on the timegraph and check for dropouts.
How are other devices performing?

The downstream stats look fine, the upstream is running a tad warm which should not be a problem if stable.
The network logs would be useful.

Re: Network Log Critical Errors - Hub 3

Hi, Well the 5GHz seems fine, but the 2.4 is terrible going from -30dBm to -90 approx every 2 mins, i presume you call these drop outs, so maybe i will have to call Virgin, i did notice some other Virgin networks dropping out so possibly they have got a problem.

i have sent some feedback to insidder re it would be good if we could record drop outs, as would Virgin believe what i say, mine goes along quite nicely, then all of a sudden drops out. The 2.4 is on channel 1 with a co channel 5, overlapping 1 network, but all of them have terrible signals in the -90dBm range.

Is this down to Virgin to sort out, or is it my problem, do the drop outs happen because too many on the network, i will be guided by your help and advise.

Many thanks
