That is more than just internet or other soft problems. You need to reflash the SD card using the image in the #2 post of this thread.

Remove the case, download SD card imager and use it to flash the image here.

Let's see if I can't help you... still waiting on my C1's but been mining for long.

First of all, I figure you changed from Static to DCHP, well, the miner needs an antenna if you go DHCP (WiFi)

Secondly, to access the computer, you need be on the same subnet as the miner.

Manually change your computer's IP to 192.168.1.199 (Yes, .1.199)

You should now be able to access your miner's interface.

However you still need to directly connect to the miner itself to change its settings... you will need an ethernet cable and a router/switch.

Sometimes you can connect directly to the miner sometimes you can't, via ethernet cable... (I never use DHCP)

If it don't work directly or with a router though, you will need a switch... you may need to even change your router's IP address since some routers use 192.168.1.1 as default address which often conflicts with a mining network.

Personally, I cannot connect directly to my miners and have no idea why but works through a switch or router.

If you go buy a switch make sure you get a big enough one you can grow into with GigaBit (10/100/1000) ethernet. (No pun intended)

I got a 24 port Rosewill, has a 5 year warranty and costs around $100, tough and does its job perfectly and then some.

Hello guys .
special greetings to Mr. dogie

firstly, I would like to thank you for your great installing guide which helped me a lot to install my c1 miner .
secondly , I realy want your assisstance to make my miner mine .
I'm very new to mining so please have patience guys if you see any silly questions  .

my c1 miner is 2nd batch with cooling kit .
I'm useing 2 cooler master psu's (  620 watts & 725 watts , 85% efficiency ) to power the miner .

I connected 4 pci's to the miner ( 2 from 620 +2 from 725  in one line ) . the cooling system is working fine .
but the miner is not mining . I connected the miner directly to my labtop using ethernet cable following your  guide .
 the first thing I've noticed is that If my labtop is connected to the miner with a cable , it can not connect to the internet using wifi . 
I logged to the setting page on 192.168.1.99 to change the worker name to my username.1,
 then change network settings to dhcb . then I connected the miner to the internet cable but it doesn't mine . I note that when I turn on the miner
 it lights red around 1 minute .

 I have no idea how to find the miner page after changing the ip adress to dhcb, but I can fing what ip is assigned to my labtop if I connect it to the intenet cable .
