EAP225 Bug in Version 2.6.1 Build 20191022 Rel. 42463
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
There is a bug in this relase and VLANs do not work. Clients will just not get an address from DHCP (the EAP225 gets address for himself without a problem).
It is definitely a problem of the software because I have just unboxed another EAP225, but with version 2.4.0 Build 20181121 Rel. 55897 and it works.
Also this one worked before the update.
TP-Link, please fix this ASAP.

EAP225 firmware version 2.4.0 had a bug which was fixed in version 2.6.0. This is from the release notes:
2. Fixed the bug that untag packets can be transferred to SSIDs with different VLANs.
If your network does rely on untagged traffic to offer IP addresses using DHCP for different VLANs, it definitely has a wrong setup.
With a correct setup the bug fix in v2.6.0 does not change the behavior of working VLANs, no matter whether you use v2.4.0, v2.6.0 or v2.6.1 firmware. I didn't notice any problem in our VLAN setups for EAP225 when upgrading to v2.6.0 and v2.6.1.

@R1D2 That would be strange, because I have the following APs working without problem.
EAP110 versions
3.3.0 Build 20190301 Rel. 39365
3.4.0 Build 20191014 Rel. 37239
EAP115
3.2.0 Build 20181211 Rel. 51136
EAP225
2.4.0 Build 20181121 Rel. 5589
The only EAP that has problems is the one I updated to 2.6.1.
Could it be that my network setup is wrong, but in this case - all the mentioned versions have still the bug you mention ? Then this is an unfixed problem in the complete range ?
2. Fixed the bug that untag packets can be transferred to SSIDs with different VLANs.

@shberge Does not seem a solution for me, I need this separation - this is the reason I implement a "business" solution.

If you use VLANs for separation, you also need to separate broadcast domains – each VLAN carries an own network, isolated against each other. Please post a diagram or the setup for your network including VLANs and IP address blocks.
For example, this is the typical VLAN setup we use on several sites. This works with EAP110, EAP220 and EAP225:

@RoRo7, if you want me to help you, please post your setup.
What IPs do you use, how are switch settings, which PVIDs are set, which VLAN IDs are assigned to the SSIDs, what networks are defined on the router, where are the VLANs terminated, does the router assign VLAN IDs to its traffic etc.

@R1D2 I would not post the end client setup without his permission. But on the other side, I am not willing to explain him, that he needs redesign of the network - because a single version of TP-Link EAP225 does not work.
It will not look good neither for the solution I proposed, neither to the vendor I have chosen.
EAP225 v. 2.6.1 goes to the drawer, until another release, working one is silently released. I cannot accept all the other versions are working, and the problem is on our side. It will mean for me, that all the other AP-s need fixing.

@RoRo7 @R1D2 I am seeing the same behavior when upgrading to 2.6.1. I run two EAP225v3 broadcasting two SSIDs and rely upon the EAP225v3 to tag the traffic for two VLANs. All prior firmware versions up to 2.5.0 worked flawlessly. Both versions 2.6.0 and 2.6.1 immediately caused all traffic to no longer pass upon upgrade.

@TFTCM, do you use an asymmetric VLAN setup? Asymmetric VLANs are not possible with Multi-SSID VLANs.
Please post your setup.

@R1D2 Ah, there is someone else with the same problem. Specific to single AP version (ok two versions). No assymetric VLANs here. If you are a TP-Link employee, then check what is wrong with those two specific versions. Why deny there is a problem ?
