Ethereum wallet is stuck at "looking for peers"

Question

I'm trying to create a private network or test network to work with smart contracts. But when I start ethereum wallet it is always getting stuck at "Looking for peers....". Below is the screenshot for the same.

Can someone help me with this?

I'm using ubuntu 16.04(64-bit) and Geth version is: 1.7.3-stable

At first you have to work genesis file init

file name code use and file name: computer any dir file save /genesis.json

{
    "nonce"     : "0x0000000000000055",
    "mixHash"   : "0x0000000000000000000000000000000000000000000000000000000000000000",
    "parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
    "difficulty": "0x20000",
    "gasLimit"  : "0x800000",
    "timestamp" : "0x0",
    "extraData" : "",
    "coinbase"  : "0x0000000000000000000000000000000000000000",
    "alloc"     : {},
    "config"    : {
        "chainId": 100,
        "homesteadBlock": 0,
        "eip155Block": 0,
        "eip158Block": 0
    }
}

Then this commend run :

 geth --datadir "D:\CHAINDATAFINAL" init genesis.json

D:\CHAINDATAFINAL miens database directory and genesis file directory genesis file directory,Example E:\database\genesis.json

Then private network create this commend run geth directory:

geth --networkid 20 --port 60303 --rpc --lightkdf --cache 16 --datadir "D:\CHAINDATAFINAL" console

then private network create check this network commend:

$ admin 

and

network id = 20;

Important Note: After that mist/ethereum wallet open

If you have genesis file already init , then you do not need to genesis file init .Then you start from the private network commend run

try it then problem solve

Thanks you.

The problem is poor engineering behind Mist wallet (and blockchain idea in general, of course), which would not run on HDD:

you can try using parity wallet, sometimes it works:
