N900 Wifi Problems

I’ll try and keep it simple to start…I have the router connected to my pc via ethernet cable and I also run wifi to my ps3, two smartphones, and a laptop. My problem is that my computer works fine, ps3 works fine, but the two phones and laptop say I have 100% signal but will not do anything on the internet. Just bought it today, had to talk to tech support to even install the thing because it wouldn’t connect to my modem via the standard install disc.

Why will my computer and ps3 work but not the other wireless devices? Thanks!

Could be something on the configuration either the router or the mobile device.

Check on the router to see if the device is assigning a valid IP.
