This is really weird. A couple days ago, my 500gp v2 suddenly could not connect to my cable modem. I tried reset, restart, restart modem. None can work. I first thought that was the modem went wrong, but my backup Trendnet pickup the internet without any problem. So I brought this 500gp to my office, hooked up with the ethernet and my computer. Bang, I can type this message now. I am a newbe here and not network savy. I did flash mine to 1.22 when it's came out. What could be wrong here? Other thoughts: I was thinking to upgrade to 1.25 to see if the problem still exists. Here's the question. What's the difference between 1.25 and 1.25 ND which states for only some handful routers (WL520 not 500gp V2 in my case). Which one should I flash to?
