Timeout for some wifi connections

Some wifi connection might drop in and out intermittently which would cause the wget function to get stuck.

A work around for this is proposed here to timeout the wget command.

Steps

1/ ssh to the emonWRT

$ ssh root@192.168.2.1

2/ install coreutils-timeout

$ opkg update
$ opkg install coreutils-timeout

3/ Open and edit the emonwrt_forwarder.sh script: (make sure you know the basics of vi before undertaking this)

$ vi /usr/bin/emonwrt_forwarder.sh 

Replace line 63 that says

wget $ec_request -q -O /dev/null

with

timeout 7 wget $ec_request -q -O /dev/null

4/ Restart the service

$ /etc/init.d/emonwrt restart
