3cr858-91 firmware upgrade - dns error

[mpanda]

Hello,

recently I upgraded to latest 1.13 release in order to solve a recurrent dns issue.(for some reason the router did loose dynamic dns and consequently I couldn't proceed my navigation in several sites)

After upgrade everything worked flawless for a couple of weeks but suddendly dns error come up again.

I try to reinstall firmware and reset router to default settings with no result.

Nothing has changed in hardware and software config so I cannot understand what could have caused such a regression.(my system is XP pro sp2, amd athlon xp cpu, branded ddr ram, optical cable connectivity 10mbit, my Isp is Fastweb Nat lan with dynamic ip and dns)

Any help is much appreciated.

Thanks,

Mario
