Re: SYNC Timing Synchronization failure / RCS Partial Service
Same with my log as of today (though been like it since last week or so). Had external tech team on site yesterday solving a local street broadband dropouts issue. Even though my Wifi connection is somewhat okay after the so called “fix”, I noticed in the hub (3ac) router status that the UPSTREAM is using a modulation of 32 QAM on one of the channels. Now every so often I am seeing RCS Partial Service in the Network Log and Sync Timeouts. Also seem to be getting lots of POST RS errors which I am unsure about. Here’s my current log: UPSTREAM: 1 23600000 42.5 5120 32 qam 10 2 36600000 43.8 5120 64 qam 7 3 43100000 44.5 5120 64 qam 6 4 49600000 45 5120 64 qam 5 5 30100116 43 5120 64 qam 8 Upstream bonded channels Channel Channel Type T1 Timeouts T2 Timeouts T3 Timeouts T4 Timeouts 1 ATDMA 0 0 0 0 2 ATDMA 0 0 0 0 3 ATDMA 0 0 0 0 4 ATDMA 0 0 0 0 5 ATDMA 0 0 0 0 DOWNSTREAM RS: Channel Locked Status RxMER (dB) Pre RS Errors Post RS Errors 1 Locked 37.6 43 330 2 Locked 37.3 63 312 3 Locked 37.3 55 180 4 Locked 37.6 68 226 5 Locked 38.6 22 17 6 Locked 37.6 53 156 7 Locked 37.6 42 281 8 Locked 37.3 59 108 9 Locked 37.6 32 132 10 Locked 38.6 70 35 11 Locked 37.6 28 21 12 Locked 37.3 65 171 13 Locked 37.6 91 245 14 Locked 37.6 44 146 15 Locked 37.6 38 173 16 Locked 37.6 65 156 17 Locked 37.3 48 108 18 Locked 37.6 75 187 19 Locked 37.6 89 318 20 Locked 37.6 48 146 21 Locked 37.6 51 186 22 Locked 37.6 88 204 23 Locked 37.6 62 133 24 Locked 37.3 73 175 14/08/2025 20:08:55 Warning!

Have tried the suggested “Hard Reset” by VM CS1View0likes1CommentStill says intermittent signal despite tech visit
Recently had a technician to look at and solve our “intermittent signal issue”. He changed over an old cable splitter to a new updated cable splitter to balance our signals for broadband/TV services. Since then we are still having to reboot the hub 3 because of frequent disconnects on WiFi (no ethernet connection used). Does anyone have a clue what is going on please? This is madness!52Views0likes3CommentsContract -Broadband help
Currently on a 24m contract on Mixit TV package including line rental and M250 broadband speed however as I reside in a small cul de sac property with just a few family members including myself who only uses the internet for casual music downloads and general browsing behaviour I am wanting to downgrade the speed to M125 (could help lower our 24m contract price again?) If any VM staff could advise me with this that would be great. thank you Hamtrektng28Views0likes1CommentSmartcard provisioning?
Getting intermittent signal breakage on two of my V6 boxes. Have looked at cable coax tightness and seems ok there. Did run a VM service status test on my V6's and only thing that has been detected was that one box states "Smartcard provisioning issue detected" Anyone from VM or forum members with any advice or help is very much appreciated. Thank you636Views0likes4CommentsRe: EPG showing 'title not available' and 'To be announced'
Just found the solution to the EPG intermittently displaying 'To be Announced' and 'Title not available'. Whilst having building work done to the house I was aware of a wifi sender device that "apparently" interfere's with our wifi on VM TV network and displaying an empty EPG. Can anyone confirm findings?5KViews0likes3Comments
