Hi,
My internet connection is going down on average once a day. When it does go down it is normally only briefly but the connection is completely cut. This seems to have started after upgrading to the Hub 5. Any idea why this is happening?
Here is the network log of when it happens:

Firstly... Can we check… are your issues only evident on wifi connections or do you see them at the same times on devices connected on ethernet cables? If you don't know, can you check on one to help diagnose whether it is just a wifi issue or it could be network connection/Hub related?
If ethernet connections are affected see this
______________________________________
Do a Hub “pinhole reset” - first make sure the 2 passwords on the Hub sticker are still there and legible first ! With the Hub still "switched on" throughout, press the reset pin in firmly with paper clip/SIM tray tool or similar "thin thing" and hold it firmly for at least 60 (a timed sixty) seconds, release the pin, leave for 5’ to stabilise - dont manually switch it off at any time. Passwords and SSID’s will reset to those on the sticker so log in and change them back to what they were/want them to be.
Then, Post up all your Hub/network connection details and someone will check to see if there is a problem there.
Navigate to these “data pages” and just copy/paste the normal “Formatted Text” (not images) - 3 FULL sets of data onto here – 2 tables from the Downstream, 2 from the Upstream, & the Network Logs pages. 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). If character limits are “exceeded” - just do two posts
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
