It started around 2,5 hours ago and the trouble is still here. Miner connects (Claymore GPU 3.4, nothing changed in settings; on port 7777 but acts the same on 5555; pools.txt is empty, using only .bat file for mining with no backup pools) after few tries - never from the first attempt, stays connected then disconnects, connects again... Or it doesn't at all. Then I shut it down and start it again. Acting erratic with no pattern...

Reinstalled drivers so it wasn't a software issue. It needed two attempts to connect. Currently it is connected but will see how long and will it get more disconnects and reconnects or will it stay disconnected...

Also the hash-rate which I see when the share is found increases way slower now. Takes 30 minutes to climb from starting 250 H/s to 300 and it still didn't top out on 330 where it should be! Pretty sure it wasn't like that before...
