I have got this problem since BETA4, but some time it was less frequent then it is now. I have 3 wi devices and problems appear only on that, which is used by ospfd(but neighbor router uses similar configuration and doesnt have aby problems with that, so i dont blame ospfd). When i switched the link to wi2, wi1 stopped timeouting(but wasnt used) and wi2 started, so i dont think that it is hw problem. I would be most grateful for any advice..
