From my understanding, that's a router setting, and usually not set if you have it set to allow all traffic. Even if you had the same model as I have, I wouldn't be able to tell you where to look to change it at this time. :icon_eek:
Correct. It normally would have been set that way by the consumer. If you setup your own router and don't know what this is about then I doubt its set that way. It isn't all that easy to do, but some routers do set it to some extent (at least other forums have posts suggesting so). So I would look at your router for something like access restrictions.
I recently read about some issues with Android and 802.11n routers but have been unable to confirm. A quick search for your router indicates some others have issues connecting to it. Either way, we need to ask some questions to go forward.
1. Is your router still supported with updates and if so, when is the last time your router was updated?
2. What encryption standard are you using on the network (WPA, WPA 2, WEP)?
3. Is your router set to multimode or N only?
I'm sure there are more, but I've only had 1 cup of joe so far.
Basic troubleshooting would include:
1. Power cycle both devices.
2. On the Android, remove and re-enter all wifi settings, try a power-down with a battery pull. Perhaps a bit later we'll get to a factory reset, but its probably a bit early for that right now.
3. Temporarily disable the encryption for the network and try to connect. If it still fails, try switching between multimode and N only.
4. Try changing the networks broadcast channel (get wifi analyzer from the network to find a clear channel).
If the router is old and not supported then its time for a new one. They all have bugs and require updates, so running an old one is probably unsafe anyway. I'd recommend one from Buffalo Technology if you have a geek around to help configure it--you could also use their easier to configure ROM, but I don't recommend it.
