My BEFW11S4 v3 has all sorts of problems and there have been no recient firmware updates for it. Someone told me that upgrading to the latest v4 firmware *might* work. The only problem is it refuses to let me update it because it's the wrong version. Does anyone know a way around this? I don't care it there is a risk of killing the router since I'll otherwise have to buy a new one anyway. Thanks.
