Could someone please look at my slow speeds and tell me what is happening

After line repairs in the street for water damage, my fibre broadband has become slow. I used to get around 30Mb download and 4-5Mb upload.

However after the repair, I am getting around 15Mb down and around 1Mb up. The modem itself reports 

The download speeds are about twice as fast as the old broadband used to be. The upload is terrible though, that's what it was before the fibre upgrade.

I would be grateful if someone could look at this and suggest solutions.

Many thanks
