@Wizz - The EAP225 seems to work well. It does all the things that the WA1201 promised.

I have now bought a 2nd EAP225, the WiFi covers about 200 m2 of open indoor space and my customer seems happy.

Two EAP225's with an OC200, a TL-R605, a TL-SG2008P, two TL-SG108E's and TL-SG108S, all together make a very usable multi-VLAN, multi-SSID professional grade WiFi and wired network. It's way more expensive than i was promised by tp-link FAQ's (generic router, TL-WA2101 with TL-SG108E)

During testing, both the TL-WA1201 and the EAP225 were multi-SSID, mulit-VLAN on the same network, looking at the R605 as router for DNS resolution. On nslookup to google.com, the EAP worked perfectly *every* time - fast and accurate, the WA1201 did ok for the first few seconds after reboot, then it started to get slow, then it started to time out and within a few minutes, it was timing out almost every request.

Both WA1201 and EAP were on:

VLAN 1 - 192.168.0.1/24 <— Admin

VLAN 10 - 192.168.100.1/24 <— Staff

VLAN 20 - 192.168.120.1/24 <— Guests

VLAN 30 - 192.168.130/24 <— Test

VLAN 1 - always resolved DNS queries instantaneously even on WA1201

VLAN 10, 20 & 30 all exhibited the same slow and timeout behavior on WA1201 but fast on EAP

Factory reset and setting up from scratch did not help the WA1201.

I have not had a chance to apply the beta firmware and test the WA1201 - it is still on my customer's site where it ended up configured as a standard AP on the Admin VLAN and is now switched off.
 

@davidraw thanks for info. Good to know 😊

@Solla-topee - please can you report back on this thread, if problem from @SuudoXR turns out to be unrelated to the TL-SG108E reporting bug discussed on post #16 here: https://community.tp-link.com/en/business/forum/topic/83046?page=2

Thanks

@Solla-topee thanks for the reply (and also for chasing the other thread), but I am actually asking you to report back if you find anything wrong with TL-WA1201 during your private investigation with @SuudoXR (UNrelated - ie NOT related to the known TL-SG108E bug)

@Wizz 

Support did indeed get in touch and after looking at my setup it was confirmed this is the known bug with the TL-SG108E.

Cheers,

SuudoXR

Ah! Great! Good to know thanks @SuudoXR

Hi, thank you very much for your time and patience.

Here is the beta firmware to fix the unstable issue under the Muiti-SSID with VLAN tags:

https://static.tp-link.com/beta/2021/202101/20210104/TL-WA1201v2_210104.zip

please feel free to update here whether the beta firmware could fix your current issue or not;

 

Thanks a lot and wait for your reply.

@TP-Link I notice there is a new official firmware out. Does this include the changes that were in this beta version?

It's been more than a year now, that a beta firmware fixing the problem has been released. How come it wasn't merged in the latest official firmware?

Can we have some news please? Using a beta firmware for VLAN is not acceptable, I expect more from TP Link. The latest official firmware comes with "Enhance device security", the beta firmware doesn't.

I have a V2 hardware version. Is it fixed in V3 maybe? I already lost time identifying the problem didn't come from my network configuration but from the TP Link device.

I would like to not also lose money by putting the device to trash.

Can I get an ETA for an official firmware with the fix included, or a refund, or another similar product with multi ssid/vlan capability?

Waiting for feedback from TP Link.

Thank you

  @Solla-topee what is the latest news please?

When can we expect an official firmware release that works for multi-SSID?
