Re: Why packets (from my ISP to me) on the WAN VC side of my router are twice the size of packets on the Ethernet (and a corresponding twice as many bytes)

Well, the first time I read your post (the one this responded to, I got the 
(mistaken, I think) impression that you thought I had the in and out 
directions backwards, so I was trying to clarify.

If I'm not mistaken again, I believe we both agree that:

Downloads from Earthlink: WAN in / LAN out
Uploads to Earthlink: WAN out / LAN in

Yes we definitely agree.

By talking about the 10 to 1 ratio, I was trying to confirm that I had the 
directions correct, in other words, using your example, my situation is:

- "Downloading" (WAN_IN / LAN_OUT) == 100 bytes
- "Uploading" (LAN_IN / WAN_OUT) == 10 bytes

My son does play one online game, "Words with Friends" on a tablet--but, it is 
nothing like a--hmm, what do they call them--3rd person shooter(??)--it is 
text oriented--sort of like scrabble--he enters a word every once in a while 
(in addition to whatever overhead is involved in soliciting an opponent online 
for a game).

Thanks, I will send it to you, by attaching it to another copy of this 
response sent to your address, only...

Note that the counters on the Westell apparently rollover at 2^32, so the 
formulas in my spreadsheet have to take that into account.  Some times I have 
to manually adjust (once so far, and I did it by a slight one-time revision to 
the formula in the given cell).
