My current rigs are all using wired connection through wifi adapter. I am planning to move to use usb wifi adapter. The reason is to make rig more compact. Any suggestions from the community. My worry is that wifi connection may not be good due to proximity of GPUs. Any recommendation for the USB wifi adapter would be appreciated. Thank you.

My farm consist of 10x 12GPU rigs. I started off with Wifi usb adaptors but as the farm grew I started having endless problems with it. When the rigs are in idle state the network was fine but as soon it`s start mining I had latency, signal drop and re-connection problems all round. I didn't even use 1mbps combined on the wifi. I guess firing up the GPU`s have some kind of impact on interference (even mounted on the roof for better line of sight)

I do however have one or two test rigs running on dongles but I dont monitor them 24/7 to check if there any disconnects.

I recommend for stability stick with wire.

wifi is ok, cables do go bad too, I have good snr on wifi with lot of rigs, however I can't use 2.4G logitech keyboard from more then about 1.5 from the rig, so maybe try different channels

Wifi is always a crap shoot  but if it works it is cool.

hard wired is far more reliable,but has fails.

The bigger and more complex you are the more wifi issues happen.

Don't commit to wifi or bust.

I wouldnt recommend wifi for mining....just another potential issue to tinker with. 

I've always had connectivity issues w/ wifi when I've run rigs on it.  I have no idea if it was my access point, line of sight issues, interference or what...I just hard wired everything and solved the problem. 

The only rig I run wireless consistently is the test bench I use to configure individual cards, test PCIE risers, etc....and that's only because I end up moving it around a lot.  I do have spare usb wifi dongles plugged into some rigs though, just in case a switch dies or something. 

My rigs are in different parts of apartment and therefore using Wired is not possible. I had to use wifi extender and connect rig to that extender using wired connection. It works usually but still wanted to find out option of removing the extender.
Thanks everyone for help.

I have rigs on wifi only..the issue is when you are mining. My fix
put one of the static shield covers from any equipment( I use the ones from riser cards) on the antenna and there will be no interference..it shields from EM interference ??? ;D
Cant comment on latency as never tried wired connection on same rigs
hope this helps

But wired internet still the best for me. I used two kinds of internet(WIFI and Wired connection) in my house for my mining rig
I used 100Mbps WIFI for my mining rig that used wifi adapter because i just focus to get the best latency. Whatever how much bandwith is not so important as long as i can get the best latency for my rigs.No doubt wired will always give you best latency but about WIFI and that needs more effort to do that. I just use Xiaomi Mi Wifi USB dongle maybe it's not so good but it's not bad at all.

Sometimes you struggle with issues on your rig, try different things, overclocks page file and all that, eventually you see that you have a bad connection problem. I'd never ever use wifi if I have a chance of having wired connection.

For extremely long cables to connect the extender/another network switch, just buy a long cat-6 cable and two (or more) RJ-45 connectors.
You can just "crimp" it yourself (if you have the tools and expertise, even time for practice is enough) or pay a computer technician to do that for you.
Usually, they only charge less than the service fee for a simple crimping.

If you are going to use WiFi in a mining farm then you are surely  gonna have connection problems as all load is on single router.

There is one more option, my rig is out of range of router's WiFi  as it is  located outside and electromagnetic waves are isolated,  so I have to  use powerline Ethernet adapters,  so far, no problems with such arrangement.

Like some of the replies in this thread, I've had issues with using wifi with mining rigs. I think if you have 1 or 2 rigs or if the rigs are more spaced apart it won't be an issue but if you got like 10 rigs, each very close to one another then you will get interference and signal drops.

The dead wifi connections were an issue because with the Claymore software, a no internet for a brief period caused the system to hang for some reason.

So I saved myself the headache and just wired up all the rigs and all the issues went away. You can just get a bunch of old router and plug one into the other if you need more ports. Each router can power up to 4 other network connections.

If there is a possible - use only cable connection. My experience with using WiFi says, that hashrate was about 10% less then by cable. I tested it about a week 2 years ago. After this test i refused to use wifi for mining.

I'm using powerline adaptors for my rigs in the garage. Works great so far. It's basically internet down your power lines. 

Wire is better, because wifi have issues sometime and i think if use wired, connection is different with use wifi. Maybe see other's reply, it is better to use wire for your internet especially for mining.

Was a dual band, load balanced decent $300 router so was around 5 rigs per channel. After I wired all of the rigs it was smooth sailing from there. I recommend wired, it takes time and effort if you want to do it properly but results = stable network 

Rather than some type of flaky wifi connection it would be better for you to use a powerline adaptor and use the copper electric cables as a route to your router, better performance and more stable

I haven't tried this but maybe if you are getting interference issues then try the following.

If you got say 10 rigs, all close together and you got instability and dropped connections. Buy about 3-4 wifi routers, doesn't need to be dual-band the cheap $35 will work.

For each router set a different channel and alternate the rigs between the channels, and maybe this way you won't et the interference.

My situation is different. I have rigs at different parts of apartment. So currently I use the cheap $35 dollar router and that works well. However the router needs to be plugged on and there is a wired connection from the router (wifi extender) to the rig. I am planning to make rigs compact and thought of replacing the wifi extender with the USB based wifi adapter so that there is one less component. This is the reason why I was looking for option for USB based wifi extender. It is possible that USB based will not work because of interference with the Graphics card.
Thanks for your message.

I have never used wi-fi.
I use wired internet, there is a RJ-45 plug on each board, a simple router costs 10-15 dollars.
There is nothing more reliable than wired connection.

And then you must read what already written by him. His problem to connect the rig at the different room. He has already used wifi adapter but it's more complicated because that needs a lot of room. a wired connection will always become the best choice but how when you have only a small room what will you do? Im feeling very complicated to use wire in this day because of that needs more room to be placed.

I am okay with Wifi, though some people faced problem with the Wifi and wired internet too. If you feel okay with the wired internet then you must go with it. For a mining farm, I would recommend wired internet connection, but if you face problems then you have another option!   

wired connection is more stable, regardless of the size of the room and premises its better to use it to connect mining rigs

Wifi is good enough for most mining operations. I have used both wifi and ethernet cabled connection for mining and I hardly notice any difference at all. You can perfectly safe go with wifi for your mining rig.

It is always better to choose wired, wired is definintely more reliable than wireless, with wireless sometimes the connection lost and by that you may missed the chance of mining or wasting your time while you are away and cant monitor your rig.
Also wired connection tend to be faster than the wireless ones so the choice obviously wired ones just for more reliability.

Well, the best thing to do now is to compare the functioning of those two and then settle on one. Personally, i don't trust wifi connections- it's either cable connection or my private data network. Wifis can disappoint many times.

We have used wifi when no other option was available, heck we even ran over a dozen rigs on using a cell phone hotspot for most of a week once.:p

Wired is definitely the best option though, pretty much set and forget that way.

Use ethernet. Latency can cause stale shares

It might work but you might get issues like I did and most of the other posters in this thread.

Wifi when its in close proximity to other devices has issues by itself. If you go to a Starbucks and there are 100 people trying to use the wifi, there will be issues.

Combined with the fact that you got some open air GPUs and lots of them, it will make the situation even worse.

Also the fact that you live in an apartment, means that your neighbours also have wifi routers which will add to the interference.

So you really should just get a network switch and just use CAT5 for all your rigs. The headache won't be worth it.

It all depends on the quality of your router, the quality of your wifi adapter in your computer, how far the distance from your router to your wifi adapter, how many other wifi networks around in your area.

If all those factors are good, there is hardly any difference between wifi and wired.

Wifi is always worse then wired connection. It`s unstable even if the distance between router and computer is 2 meters. For gaming, internet - this is ok, but in mining this is losses. I calculated difference - it have been about 10%. Router was about 4 meters from rig

This is an interesting topic. I mine out of my garage and once I get enough rigs going the garage door opener remotes lose range.

Go with hard wires and be happy you wont have to worry about it.

MY rigs are all in different parts of an apartment. If I need to provide wired network , I would need to manually run wires to the rigs from router.

This is what im trying to avoid thats why on my first mining operation i didnt tend to consider on using up Wifi but rather choosing up cable instead.
I know the reliability when it comes to connection,it might fail but not as severe with possible Wifi interference.

This is one of the advantage on having a cable yet you can utilize or solve out some sort of things when your rig cant able to receive wifi signal due to some circumstances.

So if your rigs are hardwired, your rigs is not connected to a single router, and not all load is on a single router ? ? :) how many routers are you planning to use  for a few rigs whats are located in a different area of a apartment ?


Wired connection is always better, i would say the best. Its really doesnt matter you are using Wifi, Wired or PNA , if its set up right, you sould be good to go without any issues.

You have a few option other than wired connection, but not not much :)
Im posting links for you , so you can read and understand  better what im saying )

-Wifi - if you set up right , you cant have any issues ... get a access point with beam forming (https://www.pcworld.com/article/2061907/all-about-beamforming-the-faster-wi-fi-you-didnt-know-you-needed.html) and MIMO (https://www.networkworld.com/article/3250268/what-is-mu-mimo-and-why-you-need-it-in-your-wireless-routers.html) function.
Example enGenius EAP 1250 (https://www.engeniustech.com/compact-indoor-wireless-ap.html)

If you dont want to wire anything, not even the access points, you have a option to build a whole home mesh wifi system (https://www.engeniustech.com/enmesh-wifi/enmesh-whole-home-mesh-wifi-system-how-it-works/), using the EAP 1250 what i linked earlier .

-Powerline Network Adapter (https://www.lifewire.com/what-is-a-powerline-adapter-1846813), need some kind of short wiring, but you can use everywhere in your apartment.

I have also tested this many times and I hardly see much of a difference. 10% sounds like a lot. What is the quality of your router and wifi, is it some cheap chinese junk? From what I can see there is less than 1% difference between wired and wifi.

Definitely, 5Ghz wifi is OK, it's fast and things but sometimes it lost its connection not to mention that the wired connection is definintely A LOT stable because it is wired. Even for gaming wifi sometimes sucks because there's lost packet and stuff and that's kinda not worth it for business and it's for mining which requires more intensive work, also wired is cheaper, I can't see why people prefer to buy expensive wifi than ultra cheap cat6 LAN cable

Yes, wired is cheaper and possibly slightly better, but who wants those long nasty cables running through your whole house/apartment. Wifi is so much cleaner looking and don't mess your floor up.

Wired is the only reliable solution. Not all Wireless packets make it to the destination.

MikroTik RB2011. I dont think that it looks like "cheap chinese junk". I was not looking where is problem. I had seen the difference and solved this problem with wired connection.

i dont recommend wifi as your connection to your rig, i will not take my risk since there are many connection problem using wifi in your mining equipment, do play safe with wired internet. but if i find reliable wifi connectiom i will try it too, its seems very awesome, anyway i do really avoid chinese product on my mining equipment, i know its cheaper but it will only last for a couple month.

Wifi is a no go area for me, I don't really know why it has never favoured me and always disappoint when I need it the most. Please go for Wired

Wifi is always bond to have connection issues that's  why I never go for it, I prefer the wired  connection and that's what am using

I would prefer a wired network especially on mining rigs since they are much more easier to troubleshoot than a wireless one. The best thing to do is select a  high quality network cable  and see to it that its connectors are well crimped and maybe you could also increase your subscription bandwidth for improved connectivity. Imho.

MikroTik is a security nightmare...backdoors and vulnerabilities.

Go wired with more than 2 rigs period, otherwise you start losing rewards significantly.  Even with 1 rig it will slow you down a bit but impact started showing up after 2  rigs when I tested it.

Wi-fi is always a gamble and much more prone to problems, especially if you have a mine with several rigs and/or if the wi-fi is used by more equipments in the house...
I've adopted this logic and went for cables, but I can also tell you that in my experience these also bring you trouble, they also go bad once in a while... and it is a pain because at first this is the last test option that cross your mind....  ;D

LOL what? Looks like you advise me to use D-Link or TP-Link. Try to reset default configuration and write new by yourself for your security prefences.
Later, when i had got fully wired connection - i shutted down wi-fi.

Cheap and crappy wifi = problems. High quality wifi = no problems. There is no need to use wired, yes it's slightly better and somewhat cheaper. But you don't lose out much if you use good quality wifi.

Also it's a much cleaner setup and you don't have to have cables running all over your floor.

For sure it should be a wired connection. Wifi device it's a separate thing which you put in USB-port of your rig and it may cause issues with the stability of your system. Especially if you have numerous GPU's there.

Buy a motherboard that has wifi integrated in it, very stable and solid signal. Don't buy cheap Chinese junk that will only give you problems. Good quality = zero problems.

+ i`m not sure, never watched attentively but i dont remember mining motherboards with wi-fi.
For home miners high quality equipment may become a problem due little profit. And i`ve not seen any big miner with wi-fi connetcions.

My Wi-Fi and Internet provider itself are too unstable to use them smoothly. So the solution for me is just connecting over the wire

If you want to go for wireless which I suggest if you have money to spend,I think Netgear Tomahawk 1900Mbps Ac Router, wifi extender plus many Netgear wireless Usb will save you the trouble of cable management if you have a lot of devices.We all know wired ethernet is usually better but in some specific cases and when we have money I would go with the wireless solution I pointed above.

never trust wireless networks as delivered not a little trouble, only a wired connection. the best, fast and stable.

If you have the chance to choose from wired connection and WiFi, I would recommend the hard wired connection because the WiFi connection has so many connectivity issues which you wouldn't like to experience

idk why people still asking what the best internet connection for rig,because we know exactly wired still the best.
i using wired connection for my PC and my rig since 2017 and never get any problem about internet connection.
although, my bill payment for it x3 higher than using wifi service. but it's worth.

Of course you need stable internet connection. Wifi is totally unstable. I prefer fiber optic wire internet to ensure maximal profits. But I understand that in some places in the world still fiber optic is not possible.

Big caution based on my own experience....

I could not get Linux/Ubuntu to work with Wifi on my mining rig.

Windows works fine, but Linux just refused to work as you need to get the drivers working separately, and some had issues etc etc. In the end, I just went with Windows.

In fact, if you start typing into google - 'Ubuntu wifi..' the second drop down for autocomplete is 'Ubuntu wifi not working'. So think on that.

I am a hobbyist miner, so perhaps there is a way around this, but it was not worth the time for me.

Hopefully you're using Windows, in which case driver installs should be fine. I've had limited/no stability issues with wifi on windows.

But if you're using Linux/Ubuntu... maybe your move to Wifi will also be a move to Windows.

It wasnt a problem for me to make it work. And now there are different mining OS, that can solve your problem. For experiments i tried wifi in HiveOS - it works fine.

People still think that if there's no differences between the two wireless is a more preferable option since it's just more convenient, I mean you don't need to see cables  everywhere and could cover your entire room without the need to undergo complicated setup that's why people are still asking whether it's good to use wifi which in most of the case even if you just search it up over internet you'll easily find the answer as to why wired is the best in term of stability and reliability.

as already said sometimes before. wired connection is stable and without interruption caused through electromagnetic interferences. if you really have to use wifi connection you can try it via an access point which is in a good distance to your rigs positioned. that means you connect your rigs with a wired connection to the access point and the access point gets the connection through wifi. this will work better than using a wifi dongle in your rig but still not the best solution.

although I am not a supporter of wireless connection, but I can say one thing that I used ASUS and dlink receivers. asus prevoshodit throughout, speed and reliability!
