Ok pro miners, what about hashrates? Why when you see your's speed on the zec pool and it's look like 1.8ksol from 1 rig, but when you see your speed in miner and it's 2.3 ksol? I think internet speed has the meaning and don't forget about ping from your's rig to pool.
Pool hashrate is calculated from shares found, which VARY.
This is not an "internet speed" issue, though it might be an "internet LATENCY" issue if you have something like a Sat connection.
Mining does NOT use a lot of data bandwidth - my junk Virgin Mobile 3G cell connection had more than enough bandwidth to handle several miners, even though it rarely saw much more than 200kbps on a GOOD night.
Static IP doesn't matter unless you're running a pool you want folks to be able to use from outside your LAN.
