upgraded from 200 to 350 speed now slower and inconsistant

Hi,

I had my broadband package upgraded from 200 to 350mbps (happened 19/12/2020)and the speeds I'm seeing are inconsistent and slower when compared to 200 package, I was getting a consistent 213mbps now I'm ranging from 50mbits to a single one off peak of 263 but the average hits around 192mpbs, the homehub3 has been factory reset twice now, I've run the diagnostic test offered on the virgin media app hasn't sorted anything , its in modem mode and has been for over a year now so I know its not my router causing the issue but this too has been factory reset to ensure there aren't any dodgy settings suddenly causing an issue (which i don't think it is unless its a really unfortunate coincidence of it breaking just as virgin upgraded my package), I've run speed tests directly from the router to ensure its running over gigabit ethernet using speedtest.net as netgear offer this functionality, if anyone has had this problem and knows anything simple to sort it out before i go through customer service ideas would be welcome as i'm not sure i can face going through customer service hoops this close to christmas 🙂

Re: upgraded from 200 to 350 speed now slower and inconsistant

Can you please

Type 192.168.0.1 (192.168.100.1 in Modem mode) into your browser URL bar and press enter. 

Hub 2 & 3 When the page appears DO NOT LOG IN but click ‘Check Router Status’.

Hub 4 When the page appears LOG IN then Advanced Settings > Tools > Network Status.

Copy and paste the contents of the Downstream, Upstream, Configuration and Network Log tabs onto here, if you get a yellow / straw box warning click the Post button again. Use one post for each tab if you wish.

Please do not use screen grabs.

A Guru will be along soon to decipher the info.

Re: upgraded from 200 to 350 speed now slower and inconsistant

If possible can you set up a Broadband Quality Monitor (BQM) at thinkbroadband.com - this will give you an insight into what is happening with the signal at the other side of the Hub, it will take a few hours to get any kind of trend showing although you should post the link straight away.

Please post a 'Live Link' to your BQM on here.

Instructions for posting BQM Live Link

Under your BQM graph are two links in red.

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 in the ‘text to display’ box write My BQM then click OK - you can post the link straight away.
