Can you find signal strength through ping?

That isn't what ping is designed to do. It establishes if there is connectivity between two nodes and if so gives a rough indication as to the network latency between them. To check you wifi signal strength you'll need to look at your wifi-drivers. They all give a signal strength indication but they differ in how they do this, so it is difficult to give clear advice. For Windows the system tray is the first place I'd look.

No.

Ping (Packet INternet Groper') refer to testing signal transmission over an IP network by sending a sample code (In form of Binary) to a host and back to the sender node. The time taken sending the binary code to the host and back is measured (Round trip time).

Ping is use for many purpose e.g calculate time and distance in terms of network, how many nodes your packet has gone through. Its also use to probe domain name or Ip address. Its mostly use to test if packets were duplicated, lost, damage and latency.

BUT, If suppose you ping a remote server and there is no communication. It does NOT mean your Internet connectivity is faulty. you cannot rely on Ping to diagnose Signal strength, there are other test and software for this issue.

Both NO answers so far are correct. However, when your wifi signal gets near the fringe, weak signal, you will notice more ping drop outs or timeouts. The ping time will generally show the same numbers whenever they do connect...

NO

=

There is NO relation between PING && RF signal strength.

-

Signal strength is a factor of how much RF is reaching your device from the wireless device. Signal strength affected by building materials & construction, device quality.

-

Ping is a measurement of time/distance from your device to the device you are pinging [may not be a wireless router]. Ping between wireless device && router will be ALMOST instantaneous [ZERO]

No, I'm afraid not.

PIN tests a connection, regardless of how that connection is made - wireless, hardwire, wet string...

Most WiFi connection software will have an option to show you the signal sstrength either as "bars" a %age figure of "just good/bad/so-so".

Yes
