Valuable tip.  Thanks!

3 Mbit... isn't the 640 Kbit I was using on DSL for awhile.  AFAIK 3 Mbit 
was what the cable modem was capped at when I first got cable internet.  
(Some places were 1.5 Mbit still but Cox had upgraded most of their 
territory to 3 Mbit by that point.)  It's usable.  I just won't be able 
to do package sources updates and watch youtube at 1080p any longer.  I 
may not be able to do 1080p without buffering at all.  But 720p for a few 
months won't kill me, especially since a lot of content is either 720p 
original/max or 1080p still image anyway.

Makes sense.

Ultimately I want to put together an amd64-based router, as I said, in 
ordered to be able to put gentoo on it, and build at least base packages 
for it and my main machine at the same time.  The problem I'm hoping to 
solve is that openwrt is great, but it's different than my main machine 
and single purpose, so I really don't have time to learn how to master it 
properly.  Similarly, when I had an x86 netbook, I had a 32-bit chroot 
image on the main machine to build its packages, but I found it was lucky 
to get upgrades once a year, which made them always a major pain.  So I 
decided making everything amd64 based and building most packages only 
once, was definitely the way to go.

But $50-70 for temporary solution of a few months, and as a fallback when 
I do get the amd64-based router, isn't bad and can be considered a minor 
expense associated with the temporary, especially given that I'll not be 
having to worry about rent or utilities.  I /may/ not even worry about 
reflashing it to openwrt, but I definitely want to keep the option open, 
so want an openwrt compatible device.

Thanks.  Another valuable tip. =:^)


I'll be working thru Friday, but have the weekend and early next week 
(thru Wednesday anyway) off for the move.  So unless I simply reconfigure 
the G for the first few days and see how it goes, I'll probably make the 
trip to Fry's Sat/Sun/Mon, of course cross-checking frys.com against the 
openwrt site to get an openwrt compatible before I go.


So there's a few more days left for recommendations if anyone else has 
any. =:^)
