Okay so while in-game I've been getting the message "Unable To Ping"
A LOT! lately and I don't know why. I'm not actually having any internet
troubles at all. I have other stuff up while playing Toribash and none of
that stuff struggles with internet connection and my internet doesn't show
itself to be down or anything when I check. I have no idea why I'm suddenly
getting this message a lot recently.

-I haven't updated recently or anything (Version 4.95).
-I haven't changed my router or anything recently or internet provider.
-This occurs in both public and private servers (like bet rooms and auto-tourneys)

Any idea why I'm suddenly getting this message so frequently?

This happens to alot of people i know in game i think it might just be connection with server issues
And right now it seems to be unexplained but me and of of me friends constantly get this so i doubt it's something on you're end

It happens to me too, i fixed it A BIT killing the explorer.exe process, i dont know why, i just tried it and it worked fine for about 6 hours without problem (yes, i let my laptop/toaster open all night lol)
if it doest work you can still try to update the client

-im using a 2gb ram Netbook with 1.6HZ intel quad core, and a 200-480kbp/s internet connection.
