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 (see here: Wifi network SSID not visible ), just after buying this very modem. I finally got it to work after performing two factory resets and getting rid of the Cisco "Magic" software; but this time it's not working.
I use a linksys router-modem (WAG320N) which is directly connected (via network 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 that, 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.
- 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.
Has anybody experienced something similar before?
Have you any suggestion to fix that?
Thanks in advance.
