I have a newly installed home network with the following configuration:

NetGear LM1200 cellular modem

TP-Link TL-R605 Router

TP-Link TL-SG2210MP Switch

  Ports 1-4 - APs

  Port 5 - Software Controller on PC

  Port 8 - Up-link to Router

  (Other ports empty)

4* TP-Link EAP225 APs wired to switch

Omada Software Controller running V4.4.3 on desktop wired to switch

 

I have used almost all of the default settings (single LAN and VLAN), isolation mode disabled, Airtime Fairness disabled on both bands

 

Individually, all devices function fine and have complete access to the Internet. But the client devices cannot see one another, e.g., scanner function of printer cannot see PCs to send scans to, cannot ping the router or any other client device from any connected PC (except the PC with the controller software running can ping the router, just not other devices).  There are two printers on the network and they are accessible to PCs and we can print to them.  I've tried to setup file sharing between PCs on the network and I don't see them either (I have done all PC based troubleshooting on the PCs themselves).

 

I've looked through all of the Omada and device settings and can't find anything else that pertains.  My searching on the Internet and TP-Link forums has turned up nothing that pertains.  Anyone out there have a clue what I can change to get this working?  I appreciate all assistance.

 

Thanks,

Joeh55

Hey

 

If i am reading this correctly.. this is likely the issue

 

 

Guest Network will enable Isolation, basically stop devices being able to see eachother.    It literally is for network where you want guest users (hotel, public wifi) etc and no-one to be able to see anyone else

 

Im guessing this is contrary to what you are trying to achieve.   Try disabling this and see how it goes   smiley

It'll be great if can post IPs. This helps a lot when troubleshooting your network. I don't think that's true. Nothign configured? Cannot ping the router? R605? How can you get Internet while you cannot ping the router? Post some IPs about your diagram. 

VLAN interface would isolate you from the LAN. Check this?

Hey

 

Agree with Yannie

 

If you can provide as much information as possible about the topology / IP Addresses and the setting you configured that would help.  Also include any screenshots you can, sometimes a picture can say 1000 words.

 

My first guess would be client isolation on the WiFi .. or VLAN restrictions

 

If you can give us some more meat to work with we will try to help you out

Port 5 - Software Controller on PC

 

Just noticed this.. before doing anything try dropping the Windows Firewall (turn it off) for a bit to rule out any issues there.   Running this on a desktop PC isn't the ideal scenario (OC200 or Pi is better) and seen this cause issues before, granted not this but worth a try!

I don't know if there are more settings that I should provide, but this seems to be the main points.

 

The way it stands now, The PC that runs the Omada Software Controller can ping all of the hardware devices (router, switch, APs) but none of the clients.  None of the clients can ping any other client or any hardware device.  However, the two printers (currently turned off in the pictures) can be printed to; they just can't be pinged.  My Google devices cannot be setup because my phone can't talk directly to them.  File sharing between PCs does not work; they can't see each other on the network.  It's got to be something simple.  I'm just not seeing it.

 

Hope this extra info helps. Thanks in advance.

@Philbert 

You got it in one!!  That was the problem. Now, in hindsight, it makes perfect sense. I had set that option because I wanted to be able to create Guest networks; I was not wanting to make that particular SSID a Guest network. I simply misinterpreted that option in that location.

 

Thank you so much for spending the time to look through all those settings and picking out the needle in the haystack. We are happy campers now!

 

All the best to you and yours!

Hey

 

Glad that sorted you, you are most welcome!

 

If you are new to Omada and SDN network you might be interested in this video below.. the guys helps show you how to start with basic VLANs and lockdown.   Its worth a watch if you are interested, if you get stuck just post on here

Best of luck and enjoy
