I think I bricked the tp-link router. I changed network settings to DHCP and now I cannot access the router. I think I'm gonna quit the whole hardware mining thing and just stick with cloud mining. Simply wasted money on some stupid devices.

TP-Link arrived. Connecting to TP-Link and then TP-Link to computer does not shuts down the PC. But I have other errors during configuration of cgminer which I have posted as a new thread. However, I'll update current and voltage readings once I get a multimeter.

tp-link: cgminer socket connection error. Help.

When I connect putty with screen -r command I get the following error. I am using Technobit HEX16B board. I'm following the tutorial "How to upgrade TPLINK TL-MR3020 firmware to technobit openwrt" as is. I'm using 0.3.5 version of firmware from TechnoBit.

Code:
root@HEX16B:~# screen -r 650.btc
[detached from 650.btc]
root@HEX16B:~# screen -r 650.btc
[detached from 650.btc]

I have disabled ntp client, and rebooted, but still the same.
Under the cgminer api log I get the following error.
Code:
[Firmware Version] => 20140702
cgminer: 4_3_4_48ef55a
Socket connect failed: Connection refused

What is the problem? Also for some reason I am not able to ping any address from within my network.
eg: ping 8.8.8.8 will return a request time out. But internet works. Would that be an issue? Any idea? Please help. I've been sitting with this stupid miner for a month doing nothing. Can't able to get it to work, one problem after another.

System Info
Code:
Hostname HEX16B
Model TP-Link TL-MR3020 v1
Firmware Version OpenWrt Barrier Breaker r41452 / LuCI Trunk (svn-r10276)
Kernel Version 3.10.44

Thanks.

To elaborate, simply connecting SMPS to power supply does nothing to the PC or the miner. During this time, I connect the miner to the PC via USB and the miner's fan spins and no reboot happens on the PC. But when I short the SMPS which starts the PSU (the fan inside SMPS spins), the PC shuts down.
Now I don't want to plug it into my laptop anymore. Scary. Shocked What if it blows up my whole system. I'm waiting for TP-Link MR3020 (which will take a week or so, I guess) to arrive plus a multimeter on its way.

So are you hinting that it might be a problem with USB cable? I don't have a multimeter, but I'll get one. If there is a short, will changing the cable fix the problem? Newbie here.  Wink

I've one Technobit HEX 16b which is connected to SMPS with shorted green and black wire. When ever I plug in the USB cable to my laptop, the system shuts down. I tried with different laptop, the result is the same. And the system refuses to startup until the USB is unplugged. One system's date and time gets reset after this. The PSU is has proper grounding and all. Is it something to do with power leakage? Any idea? Will TP-Link work instead?

SMPS Details
SMPS 450 Watt (24 Pin)
Input Voltage Range 220V AC
Frequency 50Hz±5%
Current 4A
D.C Output Voltage: +5V; Current: 40A Voltage: +12V; Current: 20A Voltage: +3.3V; Current: 28A Voltage: -5V; Current: 0.5A Voltage: -12V; Current: 0.5A Voltage: +5V

Thanks.
