Basically, my wifi network simply stopped working for no apparent reason. It doesn't appear in the list of the available networks anymore. I can see all my neighbors' networks, but not mine. It's as if it doesn't exist anymore. The internet connection (non-wifi), which goes through the same modem/router, is fine though.
I already had a similar problem about one year ago, just after buying this very modem. I finally got it to work after performing two factory resets and getting rid of the "Cisco Network Magic" software; but this time it's not working.
My WAG320N is directly connected (via cable) to my desktop computer (Windows 7). I have (mainly) two devices that use the wifi network: my phone (Samsung Galaxy Nexus) and an Asus tablet (TF201, aka Transformer Prime). I also resurrected an old laptop computer (Dell, running Windows XP) to test the visibility of the network, and it doesn't see anything either (apart from the 20 other wifi networks, of course ^^).
This wifi network was working just fine and has been for about a year. I haven't touched the modem settings so I have no idea what's causing the problem. The wifi LED on the device is on (green).
- making my phone "forget" about my network, hoping it would see it again after that: no luck.
- re-entering the network informations (SSID/password) manually on my phone: still no luck (says it's not in range)
- exporting the modem configuration, resetting the modem (factory reset, via modem admin), restarting it, importing the configuration: nope.
- factory reset, turning it off for 15 minutes, restarting, re-factory reset, and entering the configuration manually: still nothing.
Have you any suggestion to fix that?
Thanks in advance.
