Devices intermittent after firmware update

I have 2 hardwired connected devices (stereo receiver & apple TV) that have intermittent connectivity issues since updating the firmware.  I restored all settings after the firmware update, since i had some trouble getting everything back online.  These are the only 2 devices that drop out about once a day and it seems to be in the mornings (they work fine the night before) and will eventually restore by itself.  I have several hardwired and wifi connected devices and they all are functioning fine.  The only think these 2 devices have in commong are they are connected to a TP-Link 8 Port Gigabit Ethernet Network Unmanaged Switch (TL-SG108) then they connect to my US-16-150W.  I would normally think the TP-Linkswitch is bad, but this all started after the Firware update last weekend.  I don't have another switch handy to test and see.  Any suggestions on how to troubleshoot this?

Re: Devices intermittent after firmware update

Hello @climb_on,

 

Have you tried downgrading the devices?

Could you post your system config?

Settings > Maintenance > Support Info > Show System Config

Re: Devices intermittent after firmware update

I have not tried downgrading the firmware.  I believe, I updated the USG, both switches and both AP's and the controller.  Which would I try downgrading?

Re: Devices intermittent after firmware update

Hello @climb_on,

 

Thanks, what exact issues are you experiencing?

Do they keep their DHCP address?

What is the signal strength of the clients?

 

 

You can disable the Uplink Connectivity Monitor

Settings > Site > Uplink Connectivity Monitor

 

I also recommend the following Radio Settings ( try to use different channels on each UAP )

Devices > UAP > Config > Radios

 

2.4 GHz
Channel width: HT20
Chanel: 1/6/11 | Choose one of these channels, a RF scan will help you choose the most clean one.
Transmit Power: Low ( Medium )

5GHz
Channel width: VHT40 | Optional VHT80/VHT160 might decrease wireless stability
Chanel: 36/44 | Optional (149/157) Choose one of these channels, a RF scan will help you choose the most clean one. Avoid using DFS Channels
Transmit Power: Medium ( High )

Re: Devices intermittent after firmware update

These devices are connected by ethernet cable, not wifi.  The devices (2 cables) go to a TP-Link unmanaged switch then 1 cable goes to the US-16-150W.

Re: Devices intermittent after firmware update

The issue I have is simply no connectivity.  Each device says there is no internet connection.

Re: Devices intermittent after firmware update

FYI - the confusion is because you posted your question on the wireless forum and not on the routing and switching forum. Man Happy
