Hi from what I can see there your actual physical connection looks fine
You are connecting at 6112 so therefore in an ideal situation your speeds should be somewhere around 5Mbps.
Although saying that I notice your attenuation is 23.5 and I would expect you to be able to sync higher than you are doing.
I cant see what your SNR Margin is as it is possibly just under the attenuation figures. There is the chance that you have some spare SNR to play with.
or it could be that youve has a bout of bad syncs which could have increased your target SNR
I'm not sure who your ISP is but can you try doing a BTw Performance test please and paste the results (minus your phone no).
