I'm using a WL500W with Oleg firmware 1.9.2.7-10. Worked well for half a year. Since a month WIFI dies frequenty, sometimes several times a day. After a reset all works normally for some time.
Firmware 2.0.0.1 seems less stable (more drop downs) than Oleg.

Who recognises the problem and in particular who knows any solution?

I'm looking forward for the answers
