Cisco recently released new version of its IOS for the 877 router:
c870-advipservicesk9-mz.124-24.T.bin
c870-advsecurityk9-mz.124-24.T.bin
Giving advsecurity ios a test, and seems to work really well, also this IOS works with the various DSL firmware releases eg.adsl_alc_20190.bin.4.0.15 etc, unlike where -22 did not work! Cisco finally fixed it it in this new release 🙂
UPDATE: It seems this IOS is a bit buggy, can crash at times and create a crash dump file 🙁
Work harder cisco 😛
Thanks I will try these IOS’s on the router and see how it goes.
