Netgear FTW. Linksys: DIE!
My Netgear at home crashes when I log into a specific VOIP provider. My other VOIP provider works fine and the crashy one works fine on every other router I've tried (Billion, D-Link and iOpen)
It crashes spectacularly: Cannot ping it even from other computers. No computer can use the Internet wireless or wired. I have tried difference computers, different softphones, different settings, different operating systems. As soon as I register the router just stops responding. It has the latest firmware available (it was very unstable with the first version firmware). Close down the software and wait about a minute and it returns. If I don't shut down the software it never returns.
So Netgear is not always good!
