Gig1 Install yesterday - Speed is less than half

[Scage]

Hi All

I had TV, Broadband and Phone installed yesterday. I have taken the Ultimate Oomph Bundle and opted for Gig1 as it was available.

I tested the speed while the engineer was here and got between 200-281 Mbps over Wi-Fi to my iPhone. I asked the engineer about this and he said it would take a while to settle down but should improve within a day. 

My Xbox Series X is connected by ethernet and its network speed test says it is receiving between 360 and 380 Mbps.

I have done a Sam knows test on my iPhone and it shows speed to the Virgin Media Hub 4 as 135 Mbps and speed to the iPhone as 277 Mbps.

So I'm basically getting the minimum speeds expected of M500.

I would be grateful if someone could help me and see if there is anything in my stats which looks off. The online help all focuses on checking everything is connected and on restarting. I have gone to live chat so that the issue is recorded (obviously I'm in my cooling off period) and they said there is a priority 4 fault in my area which is being resolved at 11am on Sunday. However, Virgin's website shows a green tick and that there are no known issues. The livechat person says I will get my actual speed once this is fixed. But I am a bit sceptical of this.

I will try and post the hub 4 stats in replies to this post.

Thanks in advance.

Hi Corey

Thanks for confirming.

i have one Intelligent Wi-Fi Pod for about 10 days but have had some issues the last couple of days (I realised yesterday this is probably due to the engineer switching Intelligent Wi-Fi off, so have turned it back on). I think I need more than one. Please could you let me know how I could get another?

Thanks

James

Hi Scage...Quite a lot of your post mirrors my issues and readings - the only thing they haven't changed was the actual Hub4 and the original cabling? Despite me still having the same issues everything appears to have gone quiet on here and from VM themselves. My latest Realsam results are these and are actually kind of average fro my test although my speed from the Hub to PC is now lower than before by around 1-200... 415/126...436/160...407/124...935/164...414/151...411/161...!!!

@Scage Hi James, as far as I'm aware we can only order the starter Pod from here you would need to speak with tech support on 150/ 0345 454 1111 for extra ones.

Thanks Tom. I called them and one more should be arriving today. If I need another I have to wait another 10 days.

Hi Ewhitey

My Hub4 has been changed. They haven’t replaced any of the cabling from the street to the house, but that was new for the install. The cabling from the wall point has now been replaced (it’s white which I hear may not be good?).

My Sam Knows readings are not as bad as yours but VM seem to be saying that it’s OK for me to have an occasional reading of 400-450 to the hub and circa 900mbps the rest of the time, there’s nothing they can do.

The engineers solution was I should buy a mesh system as he says it’s the hub itself that’s responsible for the lower than expected readings.

Thanks

James
