Bizarre Broadband Issue

[Pau4]

Hi,

I’m experiencing intermittent connectivity issues on my Sky Full Fibre 300 service.

The issue isn’t raw speed—speed tests are generally good—but the connection is intermittently unresponsive.

Symptoms include:

• YouTube buffers for 5–10 seconds, then resumes at a lower resolution before recovering.
• Social media apps (Facebook, Instagram, etc.) can take several seconds before content starts loading.
• Both iPhones occasionally drop off Wi-Fi and switch to 5G even though the Wi-Fi network is still visible.
• This happens across multiple devices, not just one.
• The router remains online throughout along with the ONT (no loss of Internet or Wi-Fi lights).

I can confirm that there is no electrical interferance, hub is out in the open and i'm only in a small flat anyway.

My neighbours are having issues too and this happened with EE as well. When an EE engineer came out his test found network faults but I have had 2 openreach engineers out through sky and all they have done is ran one test on their phone, surely if the issue is intemittent it won't always show on a line test and no one has bothered to physically check the outside network either.

My broadband just keeps buffering/going slow for a few minutes at a time, 8-9 times a day and while that happens the ping on the network not just wifi can increase massively which i have tested using terminal on my Mac. I have also tried boosters and replacing cables etc.

Sky want us to go to streaming when the broadband is like this?

I am at an absolute loss and this has been going on for ages and no one, not even the executive response group can sort this out.

I would greatly appreaciate some advice. Thanks

Sounds like radio interference to me, causing your broadband to retry an connect, keep raising it as a complaint

Thanks but I believe radio interfence doesn't apply to FTTP and It's raised as an executive complaint now. I'd appreaciate if anyone had any ideas or advice as I'm at the end of my rope and Sky don't have a clue.

Hi, does anyone know anything?

[Sanderce]

It does apply to WiFi which is radio technology using the 2.4ghz ans 5ghz channels, 

it could be anything an old microwave which is leaking as their radio frequency is around the 2.4 ghz range.

to prove it is try a wired connection and see if that drops out.

As a retired person who worked with the cheif engineer,, of a network provider, this has all the sympoms of a radio inteference problem.  It sounds close by as your fibre line cannot be affected by radio interference, but your wifi can, and as you say your neighbours are affected also. 
if it happens intermitently you have to log it down when it happens, see if you can get a pattern.  It can be something as simple as cheap electrical equipent bought off the internet. Flashing lights, alarm systems dect phones(wireless ones) cheap streaming devices old anolgue equipment, an old central heating thermostat, ad nauseum the list is quire extensive.

if you have someone who likes to create their own solution to a problem, make things that is the place to think about clearly.  
i know that this isn't the answer you wasnt but these sort of problems are an absolute bugger to find.
