Hi, I have little idea how much internet bandwidth a mining rig requires. Does it vary greatly between a 6 GPU or 13 GPU rig ?

For 12 rigs in front of a 16 port Switch, is a 100Mbps Switch fine or should you go for 1Gbps ?

Gigabit all the time. Fast ethernet is really old. All those routers, switches and hubs with Fast ethernet will use old and slow chips. You need best ping possible.

Total crap. Transaction times and bandwidth are not related like that. 100mbps will do perfectly fine for mining. You will have spare bandwidth for Remote Desktop etc.

lol, even 256kbps will do amazing for mining. You people are slaves of the unknown hehe, better you noobs research before actually do anything but i know in the end you trolls will never listen or test anything, you will just go with your own wrongness all over and over again hehe

It's not about how fast your internet is but the consistency is what it's about. WiFi is okay for mining, and even dial up works juet fine. Ethernet provides better ping but that's not really important in the grand scheme of things. Just make sure you connect your miners in a way such that they can't easily disconnect or have a bad connection.

I think you will be ok with 100Mbps. All whats matter a bit is latence of internet connection. I was using free mobile internet connection with speed 16/16kbps and had no problem (as far as the ping was under 150).

Open your routers with fast ethernet and look at the chipset. I would say it can't support 12 rigs with 13 GPUs and same with old crap switch with good ping. I had 4 rigs connected to old TL-WR741ND V4 I think it was. Ping was two times higher than with TL-WR1043ND and few devices on WIFI and the old TP-link was almost dying.
OP doesn't ask about internet connection speed...
Price differences between routers and switches with fast and gigabit ethernet are minimum... Gigabit for future use is clear choice.

Here i use 2mb download / 500kb upload for 80 gpus and no problem, so, i think 100mbps is more than enough.

whats the price difference?

not really an expert here mate but according to what I've read regarding with mining it does not require faster transfer as the pool will do that for
us the share will be according to what our device can produce we just need stable connection for the pool to receive our share hash, but don't rely
on me mate it was just what I understand maybe an expert can correct me so we both will be guided.

Your Internet connection will likely be slower than your switch.  I'm using gigabit switches since all my rigs are diskless and need to talk to the file server for the OS.

The 100MBpS router is sufficient for mining. It would be enough dial-up modem.

Dont blame the protocol because you had some junk wifi router. You have no idea what you are talking about with networking, please dont spread falsehoods.

 10 MEGAbit is plenty to handle tons of rigs - latency isn't a significant issue at ETHERNET SWITCHING speeds, your latency via the Internet to the pool is going to be thousands of times higher, and the bandwidth usage is SMALL.

 Avoid wifi - it's NOT nearly as reliable as a good Ethernet wired connection.



 With that said, Gigabit is cheap enough any more there's no point in going with less and it's got a lot more room for future expansion - unless you get the 100 Megabit gear DIRT cheap and it's good stuff like 3Com, Cisco, or Netgear "Blue Box" professional gear.

Do they still sell 100Mbps routers?

If you are running local network behind that router your rig to rig speeds are router limited, 1Gbps network is disk speed limited with hdd and router limited with sdd.

For mining only, sure, 100Mbps goes but where are the savings?

As everyone told you internet speed connection does not really matter.
Despite this I would buy the gigabit one because usually the price different is very small and it's newer hardware that will not betray you during night and make you lose profits

Yes, it was weak router, but same is with fast ethernet, why use this old stuff? As I said at first gigabit all the time, it's cheap and powerful even for future use.

This post should be on any guide.

 As of the last time I walked into an Office Depot (last year), yes.

 I'm not sure how much longer that will last, but might be longer than many folks think - 100 MBPS is plenty for most business usage, a LOT of companies are wired for Cat 5 (which does NOT support Gigabit for anything other than very SHORT runs), and they just don't have incentive to "upgrade" when their wiring would take tons of money to upgrade.

 The savings are in places that have installed base to deal with - most small miners have little IF ANY incentive to worry about "installed base of gear and wiring".

There's plenty of cheap sub-10 or 15 dollar new routers that are 300mbps (or so they claim, Chinese router quality can differ a lot). I used to have one and it worked well but range was a big issue. Lots of people don't even have internet speeds that fast either way though. It'll be a while until AC WiFi is actually needed as a base.

with how much rig dont make trouble, go to buy ubiquiti unifi security gateway (https://www.ubnt.com/unifi-routing/usg/)(router) and ubiquiti switch, all gbs internet, mining dont need much connection but have a good  router and switch is better

Yes but when gigabit router is backwards compatible and future proofed why buy ancient hardware if price is almost the same? Even if you don't need it?

That is right. I have the 8Mbps ADSL connections, it is good for my mining.

That's right you should be wise on investing for your hardware, but most importantly you knew the capability of you router most particularly the brand. You can search for any reviews of the comments for the product brand of that router. Well it seems to be having bigger advantages if that 1Gbps speed compared with the late 100Mbps, the more faster the better.

having 1GBps in mining is pointless. all brute force, hashing and other mathematical operation of digital private key are calculated locally on your mining rig, data transmission from every acknowledgement to mining pools are refresh in seconds not in a fraction of an atomic seconds and beside transaction processing is as slow as 7 transaction per second. so having an old 100MBps router/switch is enough for an expensive mining rigs.

Phone as an modem sharing connection to old laptop that works as a router does basic mining very well too, I have tried.

Question remains, if 100Mbps router costs $40 and 1Gbps router $50, what is the reason to save that $10?

That is right. If the latency of the 1Gbps is lower than the 100Mbps, then it is OK to buy the faster one.

Currently I'm running 9 rigs with 100mbps ethernet without any problems. It's just a bit slow on remote control via teamviewer.

 When the latency in both cases is measured in MICROseconds as a general rule, it's NOT AN ISSUE.

 As I already pointed out, it's often a case that the WIRING won't support Gigabit, and in THOSE cases the cost would be a ton higher and it's impossible to justify the extra cost for a router that will likely never run at Gigabit speeds.

 The other factor is that a lot of the time good 100MB gear can be had for PENNIES ON THE DOLLAR - in fact I was recently GIVEN a Cisco 48-port 100MB switch (it also has 2 Gigabit "backbone" ports) that the school district a friend was working for was going to just toss in the trash during "infrastructure upgrade work" they were doing this summer.
 My TOTAL cost for 48 ports of 100MB + 2 Gigabit ports? Well, it DID need a power cable - standard C13 that I have a TON of spares for sitting around - so ZERO.


 For reference, up to middle of last year I was still running machines on 10Base-2 (COAX) - the only reason I stopped is that all of the cards I had were ISA and I retired all of my old ISA machines when I moved cross-country last summer (they weren't worth loading up for the trip).
 10Base was severe overkill for what they were doing - but when I found a bunch of 3Com "trio" port cards at a Hamfest for $2 EACH in the early 1990s, and already had a bunch of BNC "T" connectors and patch cords, the price was impossible to pass up and I got something like 15-20 YEARS of usage out of most of those cards (I did have a couple of the 20ish I bought die over the years).


 But as I already pointed out, for MOST folks there is no reason to NOT go Gigabit, and pay the small premium for futureproofing.

having 1GBps in mining is pointless. all brute force, hashing and other mathematical operation of digital private key are calculated locally on your mining rig, data transmission from every acknowledgement to mining pools are refresh in seconds not in a fraction of an atomic seconds and beside transaction processing is as slow as 7 transaction per second. so having an old 100MBps router/switch is enough for an expensive mining rigs.
 Just make sure that you keep your mining power up, GPU or CPU. You'll be fine :D

Have you tried what 5e can do?

I am dumping them all the time. Like throwing them away for free. They are so 2003.

 You are ASSUMING 5e - a lot of businesses have 3 for wiring, not even 5 much less 5e or 6.

 And yes, I know the limits of using 5e with Gigabit (works but keep the runs fairly SHORT, or go 6 - and for serious backbone work go 6 period).

I originally had a 8 port switch then I got this 24 port https://www.amazon.com/dp/B00GG1AD9A/ (https://www.amazon.com/dp/B00GG1AD9A/)  I think I pad $125 or $130 though. EDIT: Just looked, I paid $90 for an open box.

I think team viewer has an option about local network. I'm not sure, but I felt sometimes team viewer was connecting to an outside server (Use internet connection) instead of just computer to computer via local net. Not 100% sure tho.

We need to edit the subject, it should be "10Mbps, 100Mbps or 1Gbps ethernet router" (:

Nobody sells 10MB any more (except perhaps as ancient used gear).

 Since 10Base-T had the SAME "Cat 3 minimum" wiring requirement that 100Base-T did, once the price on 100Base-T gear got low enough there was no reason at all to stick with 10 on gear replacement.

Nobody sells 100MB anymore, or if they do price is the same as 1000MB. By the cheapest you can find, case closed?

I think there is no difference between them.
