Title: synchronization for weeks
Post by: proline1 on August 02, 2015, 02:48:47 AM
I'm running Bitcoin Core version v0.10.2 (64-bit) on my home PC with Windows 7 Ultimate.  I've had it running from scratch for weeks and it still have 1 year and 17 weeks to go.  At most I've had 8 active connections to the bitcoin network, but mostly no connections.

I've found that this newest release is where this problem started for me. it was slow before this release, but this is crazy slow.  I'm on a DSL modem through my local phone company.  The only change I've made to my pc is added a SSD as the old HDD failed.  It's a fresh install of the OS, current with all updates.

Any ideas/suggestions on why it's so slow?

Your problem is that you have no connections. You need to check your router and firewall to see if they are blocking TCP port 8333. If they are, then that is why you aren't having any connections. With no connections, then you have no one to download the blockchain from and thus you won't be synced with the network.

Since he had connections to peers before, the router is likely to not be blocking port 8333 as he wouldn't have block source at all in the first place.

Could you post the logs? If you have antivirus, try turning it off and try adding these into your console.
Code:
-addnode=82.116.203.240
-addnode=84.2.34.104
-addnode=31.170.178.235

Since you are using DSL, I suspect that the connection is unstable hence your peers keep on getting disconnected.
