I can't help with your problem, never seen behaviour like that. I leave this for wiser men. What does pool side hash-rate show? I'm pretty sure miner works right but something is missing from your fw package and stats are missing a bit or two.

Do you have another location you can try them from?  Could it be something with your firewall that is preventing the miners from talking to the pool?  If you run a full node, can you try solo mining against your node?

Very strange problem, because they look like they are hashing just fine but not talking to the outside world.

I second firewall.

a few days ago I set the miner as the dmz in the router which is asus dsl-ac68u but it made no diference

i was wondering about isp as well as I'm with talk talk in uk and they block a lot of stuff up to now its not bothered me as its mainly filesharing or video steaming sites, and only been the illeagal ones so far.

I just recently got an Antminer S3 given to me that he purchased at Christmas time. I finally got a chance to work on it and I purchased the HP 1000W power supply with the breakout card.  I got it up and running over clocked to the 237.5Mhz setting with the latest Bitmain official firmware.  Took me a while to get packages to work due to the paths needing editing.  I was also having issues with wireless but after firmware update it's been running decent for about 24 hours now without losing the wireless connection or IP.

Overclocked at 237.5Mhz with 2 power connections. I wasn't sure if it would run at 250Mhz ok or not being new to this.

Is there a newer firmware that I should be using?  Is Antpool a good pool to use?   Any thing I else I should be aware of as a total newb to these miners?

Thanks

I've read everywhere that when you overclock the s3 (in my case I'm overclocking an s3+) to 250freq that you need four separate cables. I took a chance on plugging my split end cables from my corsair rm1000 into it and it's been fine for weeks. The cables aren't even getting warm and the miner is plodding away at a 503.3ghs average.

My other s3 (not plus) won't take even a slight increase in freq without chips getting errors.

Aaahhhhh that makes more sense now. Cheers.

Thanks I have updated the firmware to that version and plugged the other 2 cables into the S3.

So, did you pay for electricity? If not, that's a huge win. I only mined 1 btc with my 5 s3+s, and 1 of them is running on hybrid solar. You really don't need that many fans imho, because s3+s can run hot and still stay perfectly fine, like s1s. S5s not so much, the reliability has gone down all the way into the s7 series. I run mine in the basement and even at an ambient of 70 they don't get very hot.
