Oooh, 450 GH/s I like the way you think!
Hehe, I was actually thinking higher, but wanted to be conservative, as we've been told so many times about the Gh/s estimates being absolute minimums... Same goes for the 900 watts, because the 1000 watts was an absolute maximum, etc... For instance, my three Saturns are guaranteed to run at 200GH/s each, but with their overhead, and now Sam saying we will be able to overclock them on the coindesk interview, I'm really thinking I'll be able to make much, much more... Because the min #gh/s being what it is, the actual should be as they say, higher by a considerable margin; and that's without overclocking... now add overclocking capability, and even the possibility of Watercooling them(Not confirmed yet), we now have Sleeping Dragon, Crouching Tiger... and who knows what the possibilities are. I'm stoked.

I have a vested interest in KNC being successful, so I decided it was best to Beat back the Naysayers with honest answers.

an excellent reason to use wifi indeed, would stop a cablemodem, or dsl modem spike in its tracks.... but if I'm not mistaken, most wifi routers are already pre-configured as you say, with up-link on the RJ-45 side & down-link on the wi-fi side... or am I missing something?
Perhaps you are missing a spike on the AC line? WiFi will not negate the lightning hazard thru the AC. A smart miner will have a surge protector AT the miner. Surge protectors with telco, coax, and ethernet ports are common. A UPS would be even better so you can mine thru brown/black outs. You would need a very big UPS to mine for more than a few minutes during a blackout though. Everything in the chain needs lightning/surge protection! Miners will come to a screeching halt if your upstream equipment goes poof. Even though I posted a link to a WiFi solution I do not advocate WiFi for mining. There are security/reliability issues.

The origonal conversation stemmed from different utility companies sharing/not sharing grounds, so if your cable internet isn't sharing pole grounds on the way to your home, and gets hit by lightning instead of the POWER line, which IS grounded on every pole, it would indeed lessen the risk of lightning strike spike from the internet line, stopping at the wifi, instead of in your miner.

Yeah it is all about reducing risk. No surge protector is lightning proof. A direct lightning strike is beyond the capability of any surge protector. Ohms law and all that. With circuits in parallel the relative current through each circuit is the inverse of the relative resistance of each circuit. Surge protectors work by creating multiple low resistance circuits to the ground (which only exist at high voltage). With multiple circuits and much lower resistance, due to Ohms law most of the current flows there. The key word is "most". Most is never 100% (that would require perfectly zero resistance to ground). The problem is in a direct strike we are talking about 100 kA (100,000 amps) so most is not going to be good enough. Without any attenuation due to miles of wire the full current slams into the surge protector, and even if it does an amazing job and shuts away 99.99% of the current , 0.1% is still over 100 amps. That is smoke city. Buy a surge protector but it is not a magic bullet. TL/DR: Direct lightning strike = equipment dies. End stop.

Yeah it is all risk management. Also nobody should believe a surge protector (any surge protector) can withstand a direct lightning strike, ohms law and all that. Surge protectors work by creating a parallel circuit to shunt most of the over current to the ground. With circuits in parallel with differing resistance current through each circuit is inversely proportional to the relative resistance of the circuit. The only way 100% of the current is shunted is if the resistance to ground is exactly zero (an impossibility). The ground circuit has much lower resistance so most of the current flows to the ground. Key word is most, a lightning strike can be 100,000A. With a direct strike (i.e. powerline outside your house is hit) most is not enough. If 99.99% flows to the ground that still means the 0.1% which flows to your equipment is >100A. That is smoke city. Buy a surge protector but it is not a magic bullet. indeed, agreed... Just looking at all the protection possibilities

Don't forget you will need to wire it to your power supply or get a USB wall wart.

Yeah it is all risk management. Also nobody should believe a surge protector (any surge protector) can withstand a direct lightning strike. Ohms law and all that. Surge protectors work by creating a parallel circuit to shunt most of the over current to the ground. We use the term "ground" but there is a non-zero resistance on the ground circuit. With circuits in parallel with differing resistance current through each circuit is inversely proportional to the relative resistance of the circuit. So the circuit to ground has very low resistance relative to the circuit through your miner and thus most of the current flows there. The key word is most. A lightning strike can contain 100,000A. If your surge protector shunts away 99.9% of the current, it means 100A still flows through the PUS. That is a more than enough to destroy the PSU. Now PSU has a fuse which will melt due to excessive current but no fuse is instantaneous and for a large number of milliseconds the connected equipment is going to be vulnerable. Buy a surge protector but it is not a magic bullet. Having a UPS would also help, but they can be expensive.

I've actually been using my Verizon/android phone's hotspot to mine, which works fine when using a computer to host the miners. The Units I'll be getting are actually going to be set up about 4000 miles from my home location, by me, and then I'll be going back home. So other than the usual tech call to my hired confidante, I wanted to explore every option of protection I could employ that would help... weather we decide to use it or not. Why 4000 miles away you ask? Electric is .43/kwHr here in Hawaii. Nuff said.

yes IF the miner is designed for it.
What do you mean designed for it? As far as the miner is concerned it is Ethernet. Nothing special that it has to be designed for. The miner has no idea (nor does it care) that downstream packets are traveling over a wireless link, a copper link, a sonar link, a tin can link, or smoke signal link. It sends Ethernet (100BaseTX) packets and gets back Ethernet packets. That is the whole point. Hmm, after a momentary lapse of reason... I think you'r absolutely correct.. If it can navigate to the web on an RJ45 connection, it shouldn't care if there is a wireless connection downstream or not. So, with that in mind, I think we'll need a wifi router on each side? The cable/internet provider gives you one with the service, which doesnt care what wifi device is connecting, but in our case, it will be another wifi router, hardwired to the miner, instead of a dongle or built in wifi... Am I on the same page now? Cable provider gives a docsis modem. Routers are privately purchased and/or from Vonage and are downstream of the docsis modem. Routers don't always have 802.11 but might. Routers have subnets, switches are modern versions of hubs but don't allow packet collisions. Switches don't have upstream/downstream ports, any will do. A typical home router will have one upstream port and one downstream port but that downstream port is internal and presents as a multi-port switch. A router with 802.11 will have the multi-port downstream switches (RJ-45 connections) as well as the wireless on that downstream port. One typically can't take two wireless routers and get them to "speak" to one another via wireless (without hacking the board firmware I suppose). The AP router that the link in the earlier message went to apparently can. So, if the device wakes up to DHCP to the AP which then gets an address assigned by the other wireless router then one can ssh, telnet or https in. If it had a mini-pci port, one could fire it up with a Broadcom wireless modem in the mini-pci port like one finds internal on a laptop but allowing it to connect to the internet via RJ-45 cat5 cable; then ssh in, reconfigure and restart the networking so it addresses the Broadcom wireless modem one added, then unplug the RJ-45 cable and it would be safe from lightening to cable and doing all its communication via wireless.

If you want the best surge protector buy one of these. If lightning strikes and the full power of it goes towards the surge protector.. nothing will save things but it has been documented to stop the surge when the building has been hit and only a fraction of the voltage hits it. http://www.surgex.com/whyuse.html

Perhaps you are missing a spike on the AC line? WiFi will not negate the lightning hazard thru the AC. A smart miner will have a surge protector AT the miner. Surge protectors with telco, coax, and ethernet ports are common. A UPS would be even better so you can mine thru brown/black outs. You would need a very big UPS to mine for more than a few minutes during a blackout though. Everything in the chain needs lightning/surge protection! Miners will come to a screeching halt if your upstream equipment goes poof. Even though I posted a link to a WiFi solution I do not advocate WiFi for mining. There are security/reliability issues. A spike on the AC line could damage or destroy the power supply to the miner and the power supply to the bridge but is less likely to destroy the miner if it does not have a Cat5 ethernet connection. The problem I described earlier, the grounds cut on the roadside telephone poles, increase the chances of a high potential riding in on cable, destroying the TV and anything on an ethernet from the cable modem via energy finding its way to ground through the wall 120vac. Surge protection is fine. I agree. The security issue is an element, true. So is the slower connect rate. However the time lost to a machine being down that costs thousands of dollars, is an issue. Having seen melted copper of an RJ-45 connection personally, the loss of a KNC miner to lightening is worrisome. I don't own a $2000 TV but if I did I think I'd look into only using something like WDTV via wifi and not having the cable to the box. The greater threat is the potential between the cable and the AC power in neutral in the event of a lightening strike. At least that's what I gather from having autopsied a lightening fried laptop.

mtgox price of bitcoin is not reality due to not being a true 2 way market. People are trying to get their money out of gox and failing so they have to buy bitcoin and transfer it out. Then sell for fiat. so feel free to send 100 BTC to gox and sell it. good luck getting your USD into a bank account. it could take months or never.
