500MB Fibre Broadband Poor Speeds

[mattyd81]

Hi all

i recently joined virgin media and had superfast fibre 500mb broadband installed. I only have broadband and do not have tv or phone. It is a hub 3.

when the technician left i used my phone to do a speed test next to the router and the technician and it came through at 480mb...great i said.

the day after the speed dropped to 80mb.

virgin media technician came back out and change the connector on the white box where the cable enters the property due to the 'resistence not being sufficient enough to maintain fast connection. He changed this and again ran speed tests and all was fine.

the day after again....broadband is averaging from 50mb - 200mb. i have reset the router twice and now stuck with low speeds.

I see that you can post the diagnostics on here but unsure how to access them.

help would be greatly appreciated

Stats look okay, maybe DS power is a tad on the low side, but still within spec, -6 to +10.

How are you testing speed?  It should be with a Cat6 or better cable direct to the Hub with a gigabit enabled laptop or PC.  Wifi tests are not recognised by VM as proper testing.

Hi mattyd81

Thanks for posting and welcome to the community.

Apologies for the lower than expected speed. I've done a check on the system today, no issues are showing, all levels in spec.

How's the speed been since posting and also how are you testing, wired/wireless?

Best,

[mattyd81]

Hi John

Managed to test for the first time this weekend, speeds look good but i am finding latency/lag as well as drops in bit rate.

[Paul_DN]

Hi mattyd81,

Thank you for reaching back out to us and for the update, glad to see the speeds have improved, in regards to the latency So we can get a better idea of what is happening please set up a free “Broadband Quality Monitor” to continually monitor the state of your connection and record any network dropouts. It does it 24/7/365 and it keeps a visual record of any/all your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and in discussions with us. Make sure you uncheck the “ignore ping from WAN side” box in the settings if you see a wall of "red" - note it will take an hour or two to start seeing a sensible picture. please run this for 72 hours and post the results here so we can have a further look into this for you.

Regards

Paul.

OK Paul leave it with me and i'll run it
