So you should probably use a mini VINT build 12548, (read below) for the version 1.1 and a micro Build 27858(below) is often recommended for the version #5.

Most routers should use NEWD rather than VINT when they can. VINT is for old routers that cannot support the new wireless drivers and have a correv of 4 or less.
Correvs for many models are listed in the wiki:

If you have dd-wrt installed, here the command that you send to the router to check:

nvram get wl0_corerev

I suggest you ditch the router and buy a new one.

2 MB Flash + 8 MB RAM are simply not enough unless you are running some 3 Mbps ADSL or slower setup.
