Antminer S7-LN Network issue

[BryanC]

I have it set up with a Static IP address, using a wired connection. After a random period of time, it disappears off the network and is obviously not submitting shares. No red light or beeping, solid green light on the controller. Only way to get it back up is to power cycle. Not doing anything weird in the settings or elsewhere in the network. THe current setup is the most stable - it will go for 24 hours or so. I was using a wireless bridge at first that would cause this problem in just a few hours.

Thoughts?

Thank you!

try using  a different password  not root.

also is it behind a router  that has a password.

all my miners are behind a router that has a long password.

Also can you share a picture of your network settings page? With network issues I'm just curious to see what your settings are in there.   

Did you try without wireless bridge and see what happens? (don't know if that is a option for some it might not be).   I'm really curious to see what it would do direct to router.   Or if you have another wireless bridge if you can try it.

It is completely inexplicable, but that fixed it. I'm going to go back and see if it holds with the wireless bridge and powerline ethernet options. Thank you!

I have 2x S7-LN that sit together behind two different routers and a wireless bridge. The username/password was left at their default values and I have experienced no network issues.
modem>>>router>>>wireless bridge>>>router>>>switch>>>miners

At one point, I had the miners arranged behind three routers and there were no issues there as well.

Do you have anything that could be interrupting your connection for long periods of time?

I tried using OPE (over Powerline Ethernet) to run a link from my house to garage using TPlink's latest modules. Worked great until the garage got to ~95F. Then they dropped the connection to each other. Odd thing is the lights on them are merrily blinking away like there is traffic but the miner beeping says otherwise.... Have to unplug it for a minute then plug back in,modules find each other and all is well until temp gets too high again.

Even the one in the house runs rather warm so add a hot environment and the dice are tossed.

I'm on fiber (formerly Verizon) that is pretty solid. Definitely not going down at the rate indicated by the S7LN. I have tried the following configs:
1. Gateway (G1100) >>> Powerline adapter >>> miner
2. Gateway (G1100) >>> Wireless to wired client (a TP link device in client mode) >>> miner
3. Gateway (G1100) >>> CAT5e >>> miner

I had issues with all of those configs. Have had zero drops since changing the password. I've switched back to the powerline adapter to see how it performs. I really hate it when a fox for something makes no sense in terms of cause and effect, but at the moment I can't argue with the actual results.

A working unit is all that matters, but it does seem strange from a networking standpoint.

I would agree leave it alone if working.  Reading I saw "Gateway (G1100)" with quick google looks like possibly modem/router.  Is you modem and router an all in one? 

Some all in ones are total crap.   I had one I could turn off every security option it gave me tell it to allow item's on network... and it was miserable my security system did not work outside network it blocked it.   And at the time I was really into renting miners (cant remember site it's long gone), but it blocked that to.   Point is some all in ones are just total crud.

What I did was talk to fiber company (luckily mine is very nice) and got modem turned into a pass-through mode.   I needed modem as it is for my 1 gigabit internet connection but with pass-through it turned it from router to just modem, and allowed me to use my own router.   I used a asus nighthawk (takes a decent router to handle 1 gigabit, some you will lose speed if router is not made for 1 gigabit).   

But that was my magic setup that worked was getting rid of combo modem/router and using pass-through mode.

One small item to consider, though it's not very likely.

After changing your password, you might want to review various options with the S7 configuration. In particular where it is mining. At various times, usually in a hosted arrangement, somebody will find that their machine has been changed to mine on somebody else's behalf. While I think it's unlikely that your network has been "hacked" a password change would likely prevent any previous exploits from working.

Just something to consider.

Change router from default password and add a decent one is a good thing to do.   It should in most cases keep someone from getting on your network (there always could be exploits we don't know about) so can't say 100 percent sure but I can say with a decent password on my router I have not had a single issue with miner being changed to someone else (granted it's just me on network with my miners to).

What hosting center are you having that issue with? Is it a lower budget one?

[BryanC]

It's the latest customer equipment from Verizon for their fiber service. It's a router (wouldn't call it a modem). I've gone through that whole evolution with Verizon (now Frontier) on the configuration. If they put it in a non-standard config, then I get zero support when there is a network issue (until it is reverted to a supported configuration). With the change from Verizon to Frontier, let's just say that it's already difficult enough to get support. It's actually a fine device for a consumer.

I've been running powerline ethernet for a day or two now with no dropouts. There has to be something wonky in bitmain's default image that gets refreshed/overwritten when the password is changed.

So the password change is holding on?

I have had this with 1 s-7  I altered password and was fine from then on.

[BryanC]

Affirmative - all is well after the password change! Many thanks!
