broadband cutting out

Tuning in

Hi guys my broadband has been rock solid since you last helped me out until the last day or two.

my broadband cut out last night while it was raining for a short while mid evening and ive noticed that the brown cover where the cable is coming into my flat is missing. I presume that is what is causing the problem. but when i log into my hub 3 on the hub over view on the front page ive noticed i get internet(Partial Service (US only)) logs will follow as i know i will be asked for them. any hep would be appreciated. edit Ive tried restarting and resetting the hub but the logs have stayed pretty much the same. although  ive only noticed the one drop out so far.

Not looking good. Only 3 up channels not 4 and logs look awful. Down power levels are all high too (albeit in range).

Can you do a reset and set up a BQM as per below.
__________________________________________

Do a Hub “pinhole reset” - make sure the 2 passwords on the Hub sticker are still there and legible first ! Disconnect any ethernet cables from the Hub (leave the coax connected), and then with the Hub still "switched on" throughout, press pin in firmly with paper clip/SIM tray tool or similar "thin thing" and hold it firmly for at least 60 seconds, release the pin, leave for 5’ to stabilise - dont manually switch it off at any time.

See if that sorts it.
____________________________-
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.

Hi jbrennand thanks for replying; ive already tried a pinhole reset earlier after turning the hub off for 5 min and then back on again. in the meantime ive set up a think broadband monitor and will let it run for awhile. strangle this was the only drop out ive noticed it and just seemed  strange that  the logs seem similar before and after a restart and reset of the hub. wish i had noted the logs before the reset to compare now 🙄

Hi jbrennand ive started running the broadband monitor and heres the link  for the monitor  broadband monitor

It does look a bit spiky so far!

Since posting the data above, did you do the reset again and if so have you now got 3 up channels?

If not, try it again.

BQM looks longer - there are a few spikes and dropped packets though.
