Replacement for Hub3?

[Riffraffs]

Yet again the Hub3 is dying.
it will randomly reboot, often this factory resets the device, so I have to set up the wifi & passwords again. but worse is the fact the time from it turning off until I can log in is 19 mins!!!
that is unacceptable, if I upload the config it has to reboot to take effect making it 40 mins before I can reconnect with wifi.
the hub 3 is obviously not up to the job, so I am looking for a replacement, what can I use to connect from the Coax to my switch? 
The Wifi, DNS & DHCP is all been offloaded to other systems, but the hardware still can't keep the connection alive.
this is the second Hub 3 to take 20 mins to boot, this one is 2 months old.

The VM staff on here are all well trained UK based and in "direct" contact with the staff who look after the VIP members - not the usual offshore, script reading ones whose sole purpose is often to get you off the phone asap 🙂

So is there a Tech visit tomorrow?

If so, they will disconnect all your 3d party equipment (none of that is their concern or within their balliwick) and test the Hub's initiation parameters and when done,its network connection status on their laptop/phone. Interesting to see what they say about that.

If its poor they will replace the Hub and investigate any network fault. If they say its good (they will show you that on their gear) and leave you to reconnect all your kit. Occasionally you will get an "enthusiast" who will wait and help test that - depends on their enthusiasm and workload - tea and biscuits may help 🙂

most of what you have connected is way beyond me but i am puzzled when you say you have offloaded the DHCP from the hub - maybe i have that wrong - with the hub in router mode it is controlling DHCP - whatever you have down the line is in effect double nat and that can give problems

i say again its way beyond me but thats just seems wrong - happy to have it explained

In settings > advanced > DHCP > DHCPv4 server - Disabled.
This way I can set the DHCP lease time to 6 hrs, & have static entries for the local devices (my devices that may not be on at the time etc).
When I build a Mobile, I build configure, package & send, so a 24hr IP lease is not needed & I can control the DHCP leases via RSAT controller.
I did have the hub (old one) in modem mode.

Remove all cables, turn off power & wait till white solid light & no green or green flashing 19-20 mins.
just 1 device connected via cat6 running ping -t response after a min but time jumping from 2ms to 958ms & periods of time out. until around 17 mins.
if I open the landing page I either get "someone is already logged in" or the blue wallpaper version until around the 15 min mark, but attempts to log in are met with "page not responding".

Completely understandable, I strip tested down to 0 connections & 1 device cable only. to rule out my systems, checked the logs on the firewall, switch & server to look for any related issues.
Last time I noted the settings then powered down the Router for 12 hrs, factory reset & reapplied the settings, worked for about 2 weeks then it rebooted again.

Whilst waiting you could show us the Hub stats and connection data and set up a BQM. Bit of faff but "might" reveal some problems

This is the protocol - although I am guessing you already know this 🙂
_________________________________________________________

In your browser’s URL box type in http://192.168.0.1  (or http://192.168.100.1 - if in modem mode) and hit return. On the first page up [there should be no need to login if you have done so before unless you have the New Hub4 when you do] click on the “router status” icon/text at bottom-middle of first page up and then copy/paste as “Formatted Text” (not images) 3 FULL sets of data onto here – 2 pages from the Downstream, 2 from the Upstream, & the Network Logs page. Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - if you copy/paste the data, the board software will do this for you (you may need to click the "submit" button again.

Also, in the meantime... If you haven’t already, set up a free and secure “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph” (as per instructions on the TB website) when it starts to develop.

ok - i am leaning or i think i am so go with me - if the DHCP server is turned off how can you have 3 devices connected to the hub3 - surely they cannot get ip addresses from the hub

not sure i am going to understand but try me

as to the 20 min reboot time - not sure on that - there are posts that say power on and leave the hub 20min to half an hour but thats usually on first install when the hub updates its firmware - i can only postulate that a setting is wrong - if you are in a testing mood reste the hub to defaults and try a power up again

Correct, they do not get the IP's from the Hub, the 3 devices have static IP addresses assigned (in windows or dashboard), rest of the network gets their IP from Windows Server running DHCP, Domain Controller & DNS.
the Hub is listed as the gateway IP address, nothing more. 
3 reboots today, none under 18 mins, all were power removed wait 5 mins. 2 caused a factory reset.

[-tony-]

aaaaaaahhhhhh - i understand - well i think i do - i had no idea you could do that - i know you can set static ip addys in windows etc but i just thought that over rode any that were given by the hub

its down to the tech tomorrow i guess - maybe its as simple as a faulty hub - you can push for a hub4 - i have one and just checked the setting is there in advanced - thats always worth knowing as VM tend to change things

so will read with interest as things go forward

[Riffraffs]

I WAS getting the logs, but the router rebooted & is now showing update in progress & a family pic rather than the red virgin logo

[-tony-]

well for what its worth i think its unhappy - read faulty if you want - thats a first install thing - it would explain the 20min reboot time as its going back to the VM servers for the latest firmware every time it boots 

its not as bad as one that a user had the other week - that had managed to dump the VM firmware and booted up with the Arris firmware logo
