Awhile back, there were some comments regarding throughput via routers. When I was looking at reviews on Cisco RV 120W Wireless-N, this article had a table showing average throughputs here:
For the routers listed, it ranges from around 12 mbps to 42 mbps. And this article was listed on 15 Dec 2010.
I'm not aware of all router specifications, but I must assume those listed were representative of current routers in production.
Routers do have buffers, so, it would appear if Exede's throughput was higher than what an user's equipment could handle (or parameters used), they could only "see" their router's top speed (or computer's parameters used). I have no idea what older consumer bought routers would handle on wireless side, but I suspect slower throughput speeds.
The chart was based upon 20 MHz bandwidth mode. And they have a separate page
listing various routers, and their speed specs.
In another forum here, I came across this thread,
»[Cable] Cable speeds, normal or am I just making a fuss..
where an user shows a difference between a direct connection to his computer vs router hookup. As poster notes, "I'm trying to figure out what is making the ~30mbp difference while being wirelessly connected to my router then being directly connected to the modem/router."
Also, some of the newer routers, like my new D-Link DIR622 has a default setting that is set for "QOS" enabled...which after I researched what this option does, says it measures the Quality of Service from your ISP and limits speeds to match that measurement.
Well, that QOS measurement may work fine with DSL or Cable modems, but flat slowed my Exede12 modem speeds to my computers, both for the wired and wireless computers I have. I disabled that option and speeds were back to normal again...average 18mbs...
So it's probably a good idea for everyone to poke around in their router's menu options and disable any that seems to throttle speeds to match what it thinks is the "best" for the quality of service it measured...

Recently, I came across this article:
Why do I need to occasionally reset my modem/router to fix my internet connection?
The router can run a bunch of progams on it such a webserver (which is usually how you setup a router), a DHCP server and other services for the network. The vendor hasn't tested it like it runs the shuttle - I have seen several routers actually have a setting for regular rebooting of itself every X Days/hours at a certain time. Some makes/models tend to require fewer resets in my (purely anecdotal) history - Linksys/Cisco and D-Link has worked best for me with fewest resets required.
Over time, many of the interweb connections you send to and fro - can stay open for a while on the router - consuming memory or using processor cycles. After a while and perhaps even certain operations - you may run into bugs or loops or maintenance operations that slow things down. As you push more data through a router (ie: Bittorrent, high video rates, etc) it can run out of memory, or encounter a bug that freezes the OS, or even overheats the processor.
