steemit sync node

I added all the nodes could find, I've run wallet for a week, but my wallet is not updated, blockchain remained at about 1.8G, download speed is less than 10KB, I need to do what kind of things can quickly synchronize my wallet.
My list of nodes:
seed-node = 162.213.199.171:34191
seed-node = 52.63.172.229:2001
seed-node = 85.214.65.220:2001
