comment Laptop connected to wifi but no internet
The router doesn't respond to the pings. Hmmm. Can you log into the router and see if the router receives the pings? Or ping another computer on the same AP and see if that computer receives the pings? Also please confirm that 192.168.0.1 is the correct address for the router. Do you have a firewall set up — what's the output of iptables -nvL; iptables -nvL -t nat; iptables -nvL -t mangle? Run tcpdump -n -i wlan0 as root in a terminal and ping 192.168.0.1 in another terminal, what does tcpdump display?

comment need to convert from extended-ASCII text, with NEL line terminators data or ASCII
What do you mean by “its file type is getting changed”? Where are you seeing these file types? scp copies the file exactly. Maybe the method you're using to determine the file type is different on the two machines. What Unix variant is the one that isn't Linux?

comment How to encrypt my system such that suspend to RAM works and is also encrypted
@mc0e Indeed /dev/urandom would be a better choice except on a freshly-installed system or live CD, but I think installers tend to use /dev/random, partly out of a misconception that /dev/urandom isn't suitable for cryptography and partly to be safe in the minority but existent cases where /dev/urandom is indeed unsafe.

revised Is `tail -f` more efficient than `less +F`?
`less -n` allows less to seek to the end (thanks cuonglm); mention multitail

comment Is `tail -f` more efficient than `less +F`?
@cuonglm Ah, right, it does. Just less -n is enough, that makes less use the seek-to-end-then-read-back strategy.

comment /opt partition not mounting in DD-WRT v24-sp2
Strange: are you saying that mkdir /jffs/opt doesn't signal an error, but afterwards ls /jffs/ does not list opt? What is the output of cat /proc/mounts?
