For the past couple of weeks I've noticed my download speeds dropping significantly during evening peak hours around 6-10pm ish.
I pay for the 1600 Mbps service with a minimum guaranteed 1300 Mbps speed.
I've logged speedtest results for the past couple of weeks so I can prove when the speeds are dropping.
When I do the test nobody else is on the network, it's tested hardwired on a 2.5Gbe connection high quality Cat 6 cable approximately 4m away from the router.
I've spoken to EE support a few times and they basically say everything looks fine their end and an engineer is coming out tomorrow lunch time.
Because it's not the peak time it'll work fine. How do I approach this to try and get a fix?
Below is the speed test results with date and times:
22-09-2025 20:58 - 116.82 Mbps
22-09-2025 21:09 - 144.87 Mbps
