Slow Gig 1 - even after 2 techie visits !

I started my Gig 1 service on Tuesday of last week and connected my new Hub 4 but speeds were nowhere near what I expected they are around 250meg to 300 meg, but thought it would be sorted by a techie visit

Techie 1 arrive last Tuesday AM and said he had no training on Gig 1 he did adjust the downstream power levels as they were all > 10 dbMv he adjusted them down to 5 dbMv this made no difference.

Techie 2  arrived later  that day he replaced the junction box where it enters the house this increased the downstream back to 9dbMv this made no difference so he replaced the (week old) Hub 4 still no difference.

He left me his number to contact him again if it didn’t improve I called him Wednesday and told him Modulation (Active Profile) was at 1024 and I had read this should be at 4096 but he was not familiar with this but would try to find out, that was two days ago but I have not had a response and he is not answering his phone.

I would be grateful if someone would check the stats and advise

Also if a Mod picks this up could they arrange for another techie come and try and figure out what is wrong please

Many thanks

Paul

Re: Slow Gig 1 - even after 2 techie visits !

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.

Post a 'Live Link' to your BQM on here.

Instructions for posting BQM 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.

I have not posted upstream stats as upstream speed is OK

Re: Slow Gig 1 - even after 2 techie visits !

Thanks Mike will do

 

Have you any idea what causes Modulation (Active Profile) was at 1024 and I had read this should be at 4096 ?

You need to post the Upstream data, they are all interlinked.

Re: Slow Gig 1 - even after 2 techie visits !

Hi there @fiesata 

 

Thanks for your post. Apologies for the delay in response and to hear that you've been having these connection issues despite tech visits. 

 

 How has the connection been? Are you still having trouble at the moment? 

 

Thanks,
