871W: Wi-fi to Wi-fi unreliable

As I recall, the .tar.gz one gets has the .bin and separate files for
the web stuff. Does this mean that I need to unpack it on a computer,
repack it without the web files and then get the router to load that
smaller .tar.gz ?

So it is almost 19nmegs versus 16.5 megs.

Do routers require any flash space at run time ?

This isn't about product complexity. It ia about Cisco business
practices. And now, i have to figure out how to obtain that "upgrade"
assuming it is reasonably priced.

 

Apparently the offered product range differs per country.
When I required a router for a small branch office and decided to get
the 877, the local stores (in the Netherlands) that offered it had
the Advanced IP Services Feature Set on it by default.

When I later got an 887, which uses the new method of installing a
"Universal" IOS image that gets restricted via "licenses", it came with
a Advanced IP Services license as well.

 

Not really at runtime.

If there is a software crash, the IOS likes to write a chrashinfo file
to flash, which is between 200k and 500k.
So if you have 1MB free after the IOS image (and a possible ADSL
firmware image which is about 1MB too), you are fine.

Also the RAM or flash demands in Feature Navigator are not always
correct or something like reproducable. It's a rough estimate, usually
more on the safe side.

I'm running two 876 routers with quite complex configs (for those small
boxes) with 128MB RAM / 28MB flash only with IOS 15.0.M3 as field test.
Feature Navigator demands at least 192MB RAM. Still enough free RAM left
after serveral weeks uptime.

I've seen IOS images for Soho96 routers ( 12.3(11)Tx, 12.3(8)YGx )
demanding 32MB according to FeatureNavigator that needed 48MB for stable
operations, where 32MB were merely enough to boot with an empty config.
