The Wholesale Checker estimates are just guidelines, not "could get". More "might get"
. Also, it refers to the connection/sync speed, not the actual speed test results obtainable, which are always much lower.
In your case you are connected at 15,469kbps. On O2 that should give actual speeds of around 12,900kbps, which some testers could report as 12.6Mbps.
Your attenuation of 25.5dB suggests you could connect at somewhere in the range 16,000-17,000kbps. So whatever is preventing that is nothing major. It may just be the way things are in your locality. There are many factors that can reduce your connection speed from the theoretical maximum, such as nearby electricity substations; electrified railway lines; the line passing industrial premises containing some types of electrical equipment between the exchange and you; and so on.
Regarding your own wiring, just check the usual suspects. See my Ring wire
and Miscellaneous nasties
pages.Or any similar factors at home. But I think it unlikely you have anything wrong there.
