This is no much different than your existing ZenWiFi Pro ET12 with 2x 5-port 2.5GbE switches. TL-SG105S-M2 model switch is currently $50 on Amazon. You could get about 1:1 user experience for $100 and 15min time. How much do you pay for 2x RT-BE96U routers and how many of your mobile clients need >1.7Gbps?
I have several PCs right now that are using WiFi7 adapters, instead of their 10GbE connections. I plan on reconnecting their 10GbE connections when I move them back to their permanent locations, sometime in the Winter.
They were getting 1.5+Gbps speeds, over WiFi7, with the BE92U units when I was testing them. Plus, I have a Galaxy S tablet and a Galaxy S phone that have WiFi7. Although, I don't need those faster speeds with those two devices. Plus, I have twelve or thirteen WiFi6E devices.
I had already decided to upgrade after I saw the sales prices. I got great deals on the BE92U units at under $200. Plus 5% back in BestBuy rewards, and 20% back from TopCashBack. But, with all the issues I had with the BE92U units, I really have no choice but to return them. The BE96U units were $400 each and I will get 5% back in BestBuy reward dollars, and 2% back from TopCashBack(The special 20% back was only for a few days on Asus devices. So, it sucks that I need to return the BE92U routers. It would have been nice to also get 20% back on the BE96U routers). My ET12 units were only $200 each, since I got them used. And my AX89X was also only around $200, since they were used. But, I wanted to go with new units this time.
Of course, I will probably upgrade again in two years. Since I upgrade way to often. I already went through three sets of WiFi6E Access Points. First, four Verizon routers as APs. Then two TP-Link routers as APs. And then, the two ET12 units in an AP mesh.
Also, after using Merlin on the BE92U, I wanted to get routers that use Merlin. Otherwise, I would have purchased two or three of the Rog Strix GS-BE18000 routers, since they were also on sale. Or even go back to the AX89X with the two ET12 routers in an AP mesh. But, none of those devices have Merlin firmware available for them.
Also, I'm pretty much done with TP-Link products. I would get them because they would be inexpensive. But then they would be a pain with their UI or there would be issues with them. I absolutely hate dealing with the two TP-Link wireless bridges I use. Since they were not as simple to setup as a bridge like Asus. Where I just select the bridge option. But they were ultra cheap. And I also have a TP-Link long range directional AP. That can supposedly be used for up to several kilometers. But, that UI was nowhere as bad as the UI with the other TP-Link devices I have used. But, I just have it pointing at my parking spot. So my Ring Car Cam can connect to my network.
I had also upgraded my switches to more 10GbE only switches, or with switches with two 10GbE ports and four 2.5GbE ports. But, none of that was going to be TP-Link products. And I also wanted to get rid of the four fiber connections I was using. Three 10G and one 1G. And not need to use those SFP+ ports anymore for fiber or copper. Since the Copper SFP+ modules get too hot.
