VMs Hub3 Technology ?

[CP53]

I am sure someone out there knows the tech thats inside VMs Hub3 

I have a feeling its passed its sell by date

My wifi this morning is pumping out 2.29mb/s up 0.00 down in the same room as the vm3 brick

Thinking of using vm hub3 as a frost protection in my small greenhouse as it just sits there consuming power, tried it as a modern day door stop but its to light and flimsy 

any other suggestions welcome

Things are looking up the brick is now pumping out 4.5Mb/s down  and 0.53 Mb/s up

There are still people successfully using the Hub1 and Hub2's. Most likely a circuit problem:

losing connection is this OK

No it looks ominous - can you do this.

Switch the Hub off and unplug it from the mains supply for five minutes. Whilst it's off, do a quick check that all of your coax cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure. Also check that the internal wiring is ok with no kinking or chaffing, check that all looks good with the outside cabling and wall box (no “staples, etc.,) piercing the cables.. Then switch the Hub back on and leave ~5 minutes

When all done, check back in the settings and ensure that the RS error counts and T3 errors have all reset to 0. Also that the Up qams have reverted to 64. Then check every hour or so to see if the errors start reappearing - they shouldn't. If they do (particularly the postRS and T3 ones) you have a problem (noise) that only a Tech visit will sort.

Also........ If you haven’t already, set up a free, secure and “offlsite” - “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”. Click the lower link (Share Live Graph) then click generate. Copy the text in the Direct Link box, beware, there may be more text than you can see. On here click the Link icon (2 links chain to the left of the camera icon) In the URL box paste the link you copied and then click OK
