Using Gmail with an Orbi setup

It is given me some options. Which should I use instead of -f and -i?

Seans-iMac-38438:~ seancreavy$ ping yahoo.com 1492
usage: ping [-AaDdfnoQqRrv] [-c count] [-G sweepmaxsize]
[-g sweepminsize] [-h sweepincrsize] [-i wait]
[-l preload] [-M mask | time] [-m ttl] [-p pattern]
[-S src_addr] [-s packetsize] [-t timeout][-W waittime]
[-z tos] host
ping [-AaDdfLnoQqRrv] [-c count] [-I iface] [-i wait]
[-l preload] [-M mask | time] [-m ttl] [-p pattern] [-S src_addr]
[-s packetsize] [-T ttl] [-t timeout] [-W waittime]
[-z tos] mcast-group
Apple specific options (to be specified before mcast-group or host like all options)
-b boundif # bind the socket to the interface
-k traffic_class # set traffic class socket option
-K net_service_type # set traffic class socket options
-apple-connect # call connect(2) in the socket
-apple-time # display current time

The commands differ between OS.  The link I posted was for Windows.

Also, because your issue is only with specific sites, you must ping the website or server you are having trouble with.  It looks like you were pinging yahoo or something in the last test.

Run it on Windows if you can.

And, it's -l 1492 not -i 1492.  That's a lowercase L! -i does something totally different.

Many thanks. I'll run it on the one Windows PC we have got in the house (my wiife's using it to shop at the moment - if only it was was that part of the wifi that wasn't working instead of the email systems!)

LOL!  A router that limits the wife's shopping.  That would be a big seller!

See this link where a user had the same problem.  The solution was, "I reduced the MTU of the router to 1442, and now I can can access all sites."

I'm not saying this is definitely the OP's problem, just that it could be.
