I use geth winx64 v.1.2.3 and have port 30303 forwarded on my router.
Firewall is completely off and still don't get more than 4-5 peers to be connected to.
They all occasionally drop and I keep mining my own fork. If I notice in time I will
restart geth and it will connect again to 4-5 (maybe 7) peers but nowhere near 15 or so
it used to connect before. Any idea? Is there a newer geth?
