I sync and I sync, for like 36 hours now to an SSD. Seems like the internet connection goes offline for the majority of the time I run the daemon. Turn the daemon off, internet comes back on. Any ideas?

edit: should I allow the port through my router? could be a stuuuuupid question!

    With a decent internet connection and an SSD, the sync process could take under an hour if you're lucky. Your issue is strange, and doesn't sound like a Monero problem, but I could be wrong. You should not have to mess with ports at all. It should just sync. Feb 23, 2017 at 17:14
  • Does it kill it, or just use it at its max throughput, causing other net users to starve ?

  • There's too little information to respond with a proper "answer". There's a high probability that you are pegging out CPU and/or memory on your router AND/OR eating through all of the bandwidth. Try the --out-peers option in the daemon to reduce number of connections, and --limit-rate option to limit bandwidth use by the daemon. Mar 6, 2017 at 23:40

Many cheap internet modems choke when the outgoing bandwidth is saturated. Try starting the daemon with the "--limit-rate-up=X" where X is a small value in KB/sec. You can start by allocating one third of your maximum outgoing bandwidth and see how this behaves.
