The information contained within your router management pages can really help others diagnose technical issues. To post these stats, open up a web browser and type 192.168.1.254 or BThomehub.home. Navigate to the 'Troubleshooting' Tab and then click on 'Helpdesk', you will then need to enter the admin password which can be found on the sticker on the back of BT Home Hub 4 and 5. BT Home hub 3 will have the sticker on the underside of the router.
When using a Hub 3, you will see an option at the bottom right hand corner to select 'full details'. click on this, copy the info displayed and post the results. If using a BT Home Hub 4 or 5 navigate to 'Troubleshooting' then to 'Logs'. You will then find two lines which will state 'DSL noise margin' and 'DSL line rate', copy this info and include this in your post.
The speed that matters to most people is the speed that their computer or device experience, and advice that one should use an ethernet connection is all very well except that few, if any, smart phones and tablets can be connected other than via wifi. The same is true for NOWTV boxes and Amazon Firesticks although some recent models do have ethernet ports. ISP’s quoting speeds that can be exploited only by direct ethernet connections are little short of cons to persuade gullible consumers that they can experience “blistering download speeds” if they upgrade their broadband package.
