HELP! DSL Wifi status is up, network is visible for connection, but devices will not connect

Hi,

We have an AT&T DSL modem we've been using for years, but yesterday all our devices using wifi (3X iPhones, 3X iPads, and 2X laptops,) stopped connecting to it. The devices can still see our wifi network, the password nor any settings have changed. The devices just stopped being connected and cannot reconnect to the network by wifi.

Our desktop computers connected to the network by ethernet still work and have internet access, and our wired phones still work. It's only our wifi connected devices that are perpetually 'connecting' but never connect.

We tried restarting wifi and all modem services through the AT&T Gateway UI multiple times, and also tried hard booting the modem multiple times by unplugging/plugging in the modem. Gateway seems to indicate that wifi is active and working, and the modem's wifi light has a faint flickering green light (indicating small activity from some device I guess.)

ATM, we're at a loss and considering buying a compatible third party modem, but a new modem doesn't guarantee that it will solve this problem. Does anybody here know what could be wrong or have suggestions we can try?

Thanks in advance for any helpful information.

Hi,

I finally solved the problem but the solution doesn't really make any sense.

Since we were not able to connect to our network by wifi through the normal login, I activated the 'guest' login option and found that we were able to connect to our wifi that way. Curiously, after connecting through the 'guest' login, we discovered that we could NOW connect to the normal network wifi login again.

I don't understand why or how this made any difference, but I'm guessing that the modem wasn't properly resetting through software or hard rebooting, but activating the guest login or connecting to it somehow forced a reset for the modem's primary login.

I'm leaving it up to my family members which login they want to use. I'm assuming connecting through 'guest' means no access to the printer or network directories, but that's probably more secure for our network. But without the overhead, could 'guest' possibly be faster for the devices? Just a thought. If anybody knows the answer, please post. Thanks!

For now though, please consider this matter solved.

I looked into the guest option to see if it affects anything. Normally, having a guest login does more bandwidth because it meant to securely allow additional users to share the connection.

I'm thinking since we aren't adding any more devices, any difference in performance is probably negligible.

Hey @Greenlaw, we're happy to hear that you got that resolved.

 

Not sure why you wasn't able to connect to primary connection. This could have been caused by the router not updating firmware correctly.

 

A factory reset of the router would force a firmware update. The guest Wi-Fi connection will help with network security when guest need to connect to your Wi-Fi.

 

If you have any further questions or concerns please feel free to reach out to us. Thank you for choosing AT&T.

Hi Charles,

Thank you so much for the reply and suggestion!

I'll try the factory reset to see if the firmware updates.
