Bought the N900 Monday to replace a D-Link that died after many years of service. Worked without any trouble at all until Wednesday morning. After enabling guest access, things were fine for a while, but then I lost all connectivity (could not even browse to 192.1.1.1) until I power cycled.
Hoped it was a fluke, then some time later it happened again.
I have again disabled guest access and…so far, so good.
Has been at firmware 1.05.12 since updating upon initial installation.
Have you tried factory reset setting after upgrading, I was also facing issues with the wireless but after factory reset in the Admin settings everything is good.
I assume that if I do a factory reset I will lose any customizations (I’m especially concerned about DHCP reservations). I realize that I can back up the settings to a config file (in fact, I’ve already done so), but if I restore from that file have I essentially un-done the factory reset and lost any potential benefit? Am I being too paranoid?
