Exactly as I would expect at this point. TP-Link is a joke of a company that has no clue how to make any of this expensive equipment they are selling work. We're all the fools for sitting around waiting months for them to figure out how to design firmware to make a router issue IP addresses... the most basic function of any router. Any paying large amounts of money for equipment with no more than a rock.

unfortunately I would have to echo the sentiment. I wished at this point I payed double and went with unify eco system. Now with 2 switches and 3 AP and a router I kind of stuck. Can not upgrade to omada 5 nor to the new fw version so I have to continue on the outdated software as I just need something that more or less works. I think the head of software engineering at TP link should resign and they should hire someone who can overhaul the system and introduce regiouris practises of testing and even go with TDD approach so that everyone is responsible and have tests at multiple levels.

yes this is the routers from hell, but the router is probably programmed as a middle school project without a supervisor, kidding aside. The TP-Link routers are really bad, I have them all and they are all equally buggy. 

we have to cross fingers and hope that everything is in order with the next update.smiley

until then we have to be creative to find a workaround.

  @Fae And an update on firewall features for IPv6 (there is currently no IPv6 firewall protection for 605's).

  @DannyZ I have been with Omada for many years now, I had an ER605, upgraded to a ER7206 many moons ago lol, but I have installed in the office now 1x ER7206; 1x TL-SG3428; 2x TL-SG2210MP; 3x TL-SG2008; and 3x EAP225 APs. I'm gonna be real honest, 1.2.3 for the ER7206 is the first time in at least 3 years that I have had any issues with the firmware or any of the equipment. As far as it being expensive, that's absolutely not true, Omada gear costs less than almost all of it's counterparts, and it really does show. I guess you truly do get what you pay for these days. Now, with that being said, has anyone confirmed if these things work in Standalone mode? Because at this point, if this issue doesn't persist in standalone, I might just forego the controller entirely and configure things using the Web GUIs like we used to do before we had centralized SDN networking LOL. It is rather disappointing that Fae couldn't even be bothered to reply, at this point, this was purchased for my business, not my home, and is installed in my business, I have spoken to my Attorney's and they are going to start looking at what we can do to get back some of the money we paid for these clearly not ready for business solutions.

  @havenstance  Home office stand alone. IMHO this a hardware issue and why do few of us report the problems. Got my replacement on hand, will be configuring it tomorrow.

  @KellisR 

 

Which model are you using?  What hardware version did you have and what version did they replace it with?
 

Please let us know if the newer version works!

  @KellisR I totally agree with it being hardware related, if it helps I have the ER7206 v1.6 as printed on the bottom of the router, however, the controller reports it as 1.0 and installs the 1.0 firmware revision vs the 1.6. TP-Link claims these are interchangeable, however if I go and install the v1.6 firmware from the website, this issue will take longer to recur. But alas, it will inevitably return at some point, usually in the middle of the night, and I wake up expecting to work only to find I need to roll back off v1.2.3 firmware to v1.2.1 and that stops the DHCP issue from happening, this just appeared for me with this new reivision, and it goes away after reverting back to the v1.2.1 firmware on my router, again i make sure to download the v1.6 vs the v1.0 because the v1.0 firmware will cause the issue to crop up even on firmware 1.2.1, otherwise this has been rock solid since I purchased it roughly 2 maybe 3 years ago now. I'm hopeful this is just another bug that will be fixed on the next firmware release, and if not, they need to let us know, so we can reach out the them to get these faulty units replaced, they are afterall guaranteed for life according to TP-Link. I don't mind if it was something they didn't foresee, you can't see the future when you create something, packages get depreciated, drivers as well, chipsets get dropped, etc. This platform has the potential to be an amazing time saving tool for businesses of all sizes, if TP-Link can work out the kinks, it will get better. At this point, if they can fix it for the newer units, and reach out to those of us who are having the problem with the solution for replacement, I would be satisfied for sure.

 

Edited for clarity regarding hardware issue.

  @Fae The problem still persist. I update my ER7206 with firmware version 1.2.3 and still have issues with dhcp. Some clients doesn´t receive a valid IP on netwok. The problem is solved after reboot de router, but it happens again the next day
