What kind of router/modem are you using? It may need an update on its firmware to suit your ISP's ADSL 2+2 system. After the update, you have to log into it to adjust MTU or MRU to 1492.

Check with your ISP on how far you are located from their switch station. The further you are, the lower the speed. See this pic for explanation:
