Mods: If this should be moved, my apologies. I intended to talk about this with pool people, but maybe it should be in general hardware?
This really only applies to kano.is members who have their miners at their home, who do not have fail-over internet setup, and have a cell phone with them everyday.
I wanted to mention a couple of things that some home miners may be interested in but maybe haven't thought about.
It is easy for most people to have redundant internet through your cell service via a usb modem or even just your cell phone.
It takes the right router to make this plug and play, but it doesn't have to be a $300.00 router. The right router is obviously one which can accommodate at least two NAT connections. The one you are using now, and... I have checked through various carriers and almost every big one offers some form of tethering, usb modem, or you can be creative and use your phone and PC, but my preference for ease of getting started right away is the usb modem +router.
Most of the consumer model routers I have played with use the USB port on the router.
Most people don't need an expensive router, but if you want one, I've liked
https://www.asus.com/Networking/RT-AC88U/overview/ the most out of any I've used in the past 3 months and I have seriously used 4 and played with another 6 - 8.
You don't need most of the features this offers and can find many which have fail-over, redundant, and many which claim to do load balancing. What matters is the least expensive one you can count on that won't break for the next few years unless you have a high wireless traffic household or think you will within the next few months.
You don't need Gigabit Switches and the latest and best of any communications hardware to handle bitcoin traffic. If you have the needs elsewhere in your home then I will also vouch for the Arris SURFboard SB6190 cable modem. I was able to add a fantastic hardware firewall, I use a mix of other equipment throughout the home and replaced the cable from the cable company box to the modem with the proper connections, good crimps, etc.
The cable probably made things more consistent than anything else.I have a great deal of traffic at my home and I still do not come close to using the full potential, so you do not need to spend a bunch of money, but if you are going to anyway, eh check out these things if you want.
Even if you only connect it when you are home so the internet fails over to your cell phone when you are there it covers quite a bit of time for most of us, and you can do this through your PC as well. I'm sure linux makes it much easier.
*Disclaimer, there are plenty of better products, I know, these are my experiences with my purchases, but if you have a specific recommendation regarding a product implementation to help someone have redundancy with their miners and / or nodes I am all ears. I think this is a sorely missed priority for many small miners, especially when many or maybe most already have the hardware to handle it.
Edit 1:
The iOS app for the router I mentioned is not what they show it to be yet. They have many categories listed, but most are not yet functional. Also, the MU-MIMO support has been released in alpha, but just an fyi it is not mainline. The specifications for exactly how mu-mimo is supposed to work haven't been finalized. All these companies are guessing at the standards with the routers they release. Out of them, this is a good one imo.
