Issue Description/Phenomenon:
Recently we received feedback that TCP connections (such as Remote Desktop) failed between clients connected to different VLAN SSIDs on the same EAP650/ EAP670/ EAP653. Here is the case details.
Topology & Setup:
Internet --- Router --- EAP650 SSID1 & SSID2 ))) ((( PC1 & PC2
VLAN1 (SSID1): 192.168.1.x/24
VLAN3 (SSID3): 192.168.3.x/24
Problem:
-
When the PC1 & PC2 are connected to the different SSIDs respectively, TCP connections (such as remote desktop) are broken between the two for anything beyond a simple network ping, i.e., the client on VLAN1 can ping the client on VLAN3 but the attempt to open a remote desktop connection ends up a failure.
-
When two PCs are each connected to the same VLAN SSID, the Remote Desktop connection works as expected.

And again a week without any feedback! What's going on with TP Link?!
It's not a business product from this point of view. With such bad support (no support) and slow updates you never will get Omada into place against UniFi System. So sad to see.

I'm not going to comment on UniFi support because I've never needed to use them despite the fact that I have 50-60 UniFi sites, it just works with little problems.
Maybe the long wait for firmware is because they are actually testing this time :-) just kidding.
And @Fae it would be nice if you could update us on the forum about the progress plans of TP-Link and when we can expect to get new features on devices that are not supported by new features on the controller.
Now almost everything I have only in beta and has been for a very very long time.

@Fae I think the EAP670 Series is a big scam from TP-Link

@Christian2705 He is. He is writing within other topics. So overall not a good sign from TP Link NOT to answer within this topic.

@Fae Any update on a release without bugs (new final release?) for EAP650? We are waiting since months. For such a stupid and annoying bug there must be a new release within days!

@Spryde Any update on when you'll ask for another update?
Yes, it's very disappointing and tarnishing this bug hasn't been addressed, you've aired that grievance and I share it. But only thing to do now is wait for the release. I subscribe to this thread so that I know as soon as the release is issued. All the notifications of people asking for updates are unnecessary. Fae is active, so they'll respond when there's an update, which means the answer to your question is no, there are not any updates. I don't see the value in Fae replying replying "No, there are no updates" every time you ask as it just sends further unnecessary notifications and wastes everyone's time. as no new information is relayed.
@Fae Could we consider locking this thread?
