Slow upload speeds

Hi,

I'm currently on the 350mb package and ordinarily I get around a 35mb upstream.  However, in the past few days I've noticed that my upload speed ranges between 5mb and 10mb.  And whilst my BQM is mostly normal, I experience significant packet loss whilst uploading even small amounts of data (i.e 2 or 3 photos to Onedrive).  This did not occur when I enjoyed a 35mb upstream.  For what it's worth, I've pasted my router stats below.  I've tried rebooting the router and using wired connections only.  There are no reported faults in my area.

Down channel PostRS errors are always an issue needing a tech visit. To be sure can you do this....
______________________________________________________________________________

Switch the Hub off and unplug it from the mains supply for a few minutes minutes. Whilst it's off, do a quick check that all of your coax cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure. Also check that the internal wiring is ok with no kinking or chaffing, check that all looks good with the outside cabling and wall box (no “staples, etc.,) piercing the cables.. Then switch the Hub back on and leave ~5 minutes

When all done, check back in the settings and ensure that the RS error counts have all reset to 0.

Then check every hour or so to see if they start reappearing - they shouldn't. If they do (particularly the postRS ones) you have a problem (noise) that only a Tech visit will sort.

Thanks John,

I did as you suggested and my RS Errors did reset to zero.  I've now reposted my errors below, after 30 minutes of uptime.  I have logged a call with customer services.  They have escalted the issue to their 2nd line and are monitoring my connection for the next seven days.

Thank John,

I've done what you've suggested and reposted my stats below.  I've logged a call with customer services. Even though they couldn't find a specific fault with my connection, they've esclated it to their second line. Also, the call handler told me that there is a 'short term network issue' which might affect me, but he couldn't elborate further.  He also said they'd monitor my line for 7 days.

Thank's John.

I've done what you suggested and pasted my updated stats below.  I logged a ticket with CS.  They couldn't find any faults on my line but they've esclated the issue to their second line and are monitoring my connection for the next seven days.  They also told me that there is a temporary network issue that may be affecting me,  but they were unable to elobarte further.

Hi ashgibbo61,

 

Welcome to our community forums and thank you for your first posts.

 

Sorry to hear you are having issues with your upload speeds. We are however glad that you have gotten in contact with our team regarding this who are monitoring your service. Please let us know the results during this period and if you need any further help.

 

Thanks,

@Akua_A  Can you tell us why CS said the customer needs to monitor the connection for seven days?  There are thousands of PostRS errors appearing in a minute or two after a restart - that is not going to change in seven days.  It usually signifies a noise problem that either requires a Tech visit asap, or - its a known network SNR issue.  Is that so - and if so - what is the fault reference number and estimated fix date?

An update....

I phoned the call centre again tonight for an update.  The call handler told me that my fault hadn't actually been escalted to the 2nd line and that they need to monitor my connection for seven days first.  He also told me their 'might' be an issue in my area but they couldn't give me a fault code or a definitive fix date (like the previous call handler did), he then went on to say that he could book an engineer for me, but it might cost me £20 if the engineer isn't required.  And if that wasn't bad enough, he then decided to tell me that I could be experiencing these problems because my speed (350mb) is too slow and he recommended that I upgrade to 500mb.  The customer service was that unbelievable, it felt like I was on an episode of Fonejacker!

I'll try to phone during normal office hours tomorrow and hope for a sensible conversation....

Hi @ashgibbo61,

 

Thank you for coming back to us in regards to your issue. I'm really sorry to hear that this has been your experience with our call team. This is not the service we aim to provide. Apologies. 

 

After running some further checks on your account, I can see that your upstream and downstream power levels are out of spec and not where they should be. This could be impacting your connection and causing slow speeds.

 

In order to have this issue resolved, we would need to have a technician look into this further for you.

 

I will send you a Private Message in order to confirm a few details so we can have a technician booked in for you. Please keep an eye out for a purple envelope at the top right corner of your Forum page.

 

I will be in touch soon. 🙂

 

Thank you,
