[c-nsp] Large scale rollout - which IOS?

[Garry]

Hi,

we're preparing for a ~400 router rollout. As it would really suck to 
have to go out again and replace the IOS once they are set up on site, I 
was wondering if the IOS that is currently installed when delivered to 
us will be fine, or if I should (or even need to) upgrade while we're 
installing due to some caveats or known problems ... they are 876-W-G-E 
routers, and have IOS c870-advsecurityk9-mz.124-4.T7 ... routers will be 
used w/ PCs in the (wired) LAN, as well as one or more PCs via WLAN 
(WPA2 shared key), with aDSL for WAN hookup ...

Any comments?

Tnx, -garry
