I reset my bitcoin miner and now it won't show up on my router

[NixonsCat]

I purchased my Visonman Prospector 200 on ebay from a reseller. I set it up was working fine for about an hour then the speed dropped to about 30gh/s and I could no longer connect to any pools since the connection was refused. I tried rebooting it then turning it off and on again but it did not fix it. The only pool I could connect to was slush's pool and the speed was slowly decreasing. I decided to completely reset the machine since I thought some setting was messed up and creating a problem, but after resetting the miner, the page crashed and the IP no longer existed on my router and will not connect to the ip on the back of the case. If anyone knows how to fix this please tell me.
