Since renewing my contract my broadband speeds have tanked considerably.
For the first few weeks I ignored the issue as there tends to be a settling in time with DLM. But my speeds have not improved and honestly seem to degrade more over time. The issue has just passed 4 weeks ongoing now.
From my account page my speeds are stated as followed;
Product: Fibre
Estimated Download Range: 61 - 72Mbps
Estimated Upload Range: 17 - 18Mbps
Minimum Guaranteed Speed: 54.6Mbps
Current Line Speed (Download): 80Mbps
My download speeds vary Mbps wise from the low 20's to mid 30's. There have been instances when my download speeds have been well below 20 and a few occasions where its been in the high 30's. But it is far too inconsistent and I am nowhere near my estimated speeds and far below my minimum guaranteed ones. My upload speeds never climb over 7 Mbps.
I do not have a phone line with this package so dialling 17070 to check line faults is of no use as I have seen it mentioned in several other posts.
The router is connected to the master socket (Only socket in the property.) There are no powerline adapters or Wi-Fi boosters or anything else being used.
I have also check through Ofcoms availability checker along with a few other sources and can confirm the highest speeds in my property theoretically should be 80/20 Mbps.
Attached are sceenshots of speedtest taken via LAN with no devices connected through WiFi or LAN (no apps, games etc are running in the background). over roughly a 96 hour period
On top of this I am met with random spots of my internet dropping entirely. And as stated above my speeds were much higher prior to renewing.
EDIT: Added screenshots of BT Broadband Availability Checker and Helpdesk Data from the router
