Smart plug no longer working since fiber install

Since I moved over to fiber my smart plugs stopped working.

I have tried to re add them but they time out. I have tried both  Bnlink and smart life apps. 

My modem is BGW320-505. 

I am logged into the 2.4 wifi configuration with mode of b/g/n and 20mhz as bandwidth. 

Any suggestions?

Like most of the AT&T gateways, the BGW320 has the 2.4Ghz and 5Ghz bands combined into one Wifi Network Name (SSID).  The wifi devices are supposed to interact with the gateway and come to a decision as to which frequency they should connect to.

At least that's the theory, but things like your plugs don't often do well when faced with this combined frequency situation so you've got two choices...

You have to separate the bands OR enable the Guest Wifi Network which is 2.4GHz only and point the feeder to that.

Note: At some point during either of these operations you'll be asked for the Access Code which is found on the gateway itself.

To go with the first solution, go to http://192.168.1.254/cgi-bin/wconfig.ha In the 5GHz section change the Network Name (SSID) to something else.  I usually suggest just adding a -5 onto the end of the current name.  Scroll down and hit Save.  Oh, ignore the dire warnings about the end of civilization if you change the name.

After this, any devices that work better on 5GHz will need to get their password changed to the new one you just made but the exiting 2.4 devices should just keep working. 

If you'd rather go the Guest Wifi route, go to the first Wi-Fi page (Basic Options) and Enable the Guest SSID and point the plugs to that Guest Network Name.

Hello,

I did separate all those out.  Not sure what you mean by point the feeder to that. 

I am logged into 2.4 trying to add the plugs.

I even turned off 5.0.

Any other suggestions? 


Thanks

We're here to help get you connected, Andreavw!

 

Thank you, tonydi for the valuable information regarding this!

 

Since you have changed your configuration, we suggest doing a reboot of your AT&T Gateway to make sure the changes held.

 

If you do still have difficulty connecting, we suggest checking our article on Wi-Fi Troubleshooting For Single Devices. There are many things that could be affecting your ability to connect, such as your devices needing a software update. You can find more information on that, as well as other troubleshooting steps, at that article.

 

Let us know if this helps!

Arrghh.....sorry about the "feeder" thing.  I pasted in a reply that I've used before (for someone with a bird feeder, I think it was) and changed feeder to plugs in one spot but missed the other one.

I just looked at the BNLink site and troubleshooting info doesn't seem to be something they're interested in supplying.  But I did look at the user guides and separating the bands is exactly what they say to do when faced with a router that combines both into one network name. 

Did you try the other option, enabling the Guest Wifi and trying that for the plugs?  It shouldn't matter but at this point I don't know what else to suggest.

@Andreavw and @tonydi I don't have a BGW320, but is it possible that the BGW is using WPA3 (or some other security protocol that is not compatible with the smart plugs)? Most everything I've seen is compatible with WPA2, so I would give that a shot if it's not already on it.

I've seen the response of segregating the 2.4 & 5GHz networks, but I don't recall that actually fixing connectivity issues.  If a device antenna is tuned for 2.4GHz, it will not see the 5GHz network.

For the record, I have all my networks (6 APs across 2 sites) configured for dual band operation and also have a bunch of 2.4GHz devices that have no issues. Devices include a handful of TPLink plugs and switches and about 30 ESP8266 devices.

@tinslwc  Great point about the WPA3 thing!  It's not clear to me if it does or not.  I can find stuff online that says it's not, then others that say there's a "combined WPA2 and WPA3" setting and some that just say WPA3. 

@Andreavw  Can you look in the Wifi settings for the 2.4GHz band and see if WPA3 is involved?  Setting it to just WPA2 would be a good test.

As far as the separating bands and IoT devices, there are lots of cases in this forum alone where that allowed the devices to connect.  Many of the manufacturers (including the maker of these plugs) even suggest that change.  I don't know the exact technical process involved but clearly the combined bands confuses these devices.

I can confirm that the TP-Link plugs are great little devices that just flat work no matter what you throw at them. Not so much with the more popular Wemo plugs.
