I notice you focus a lot on the CPU. What about other components of the router like the radio, FEM, etc?

I read that the AX73 is also like that, tri-core but having dedicated chip for 5GHz. I wonder what is advantage of this dedicated chip?

BCM6750 comes with 1 radio, BCM6755 comes with 2 radio. The built-in radio in BCM675x SoC is only 2x2 WiFi 6.

For higher end product, manufacturers will use a dedicated radio chip that's faster. Most if not all AX3000 and AX5400 Broadcom products are using BCM6750 + BCM43684 combo. TP-Link AX73, ASUS RT-AX3000, ASUS TUF-AX3000, ASUS RT-AX82U, ASUS TUF-AX5400, ASUS ZenWiFi XD6 and etc.

Since the router will use a dedicated radio chip, there's no point to spec it with BCM6755 unless the manufacturer is developing a Tri-Band AX6600 product then they will use BCM6755+BCM43684 combo.

In reality, there's no observable CPU performance difference between BCM6750 and BCM6755. Core count is just a marketing figure and router SoC doesn't work the same way as PC or mobile.

Note: BCM6750 is 3 core, BCM6755 is 4 core.

Yes i know but is it overkill to get ax86u? or something like ax68u is good enough price vs performance.
I am planning wired backhauled aimesh if i get another router.

I can't say was it overkill or not when I don't know how much internet connected device and your subscription speed.

Oh sorry, I should have mentioned it in my ori post.

My Unifi is 500mbps. My router AC68u is currently in living hall.
Basically now only me and my wife in the house, and we are working from home now so a lot online calls during the day, and she complained bad connection a lot lately (she is furthest away from router on second floor back room) while i am also working in second floor living room and occasionally also experience bad connection and reboot router helps restore it.

Other uses include streaming Netflix at night, downloading stuffs. I occasionally also pubg mobile on ipad while wife is streaming netflix on TV.

I generally feels the router performance has degraded a bit but not sure whether internet also a factor. 5Ghz ssid sometimes also disappear, even when i am near to router.

To be honest, I would be hesitant to just recommend RT-AX86U due to its price tag. Blacktubi had done a comparison on Asus router wireless performance so you could really decide for yourself.

If you are looking to get the best out of your wifi (close to 500Mbps) when you're 1 wall away from the router, RT-AX86U. Otherwise, Asus RT-AX3000 is a great option and I would say the price/performance is way better than the RT-AX86U.

From what you had described, it sounds like your RT-AC68U is nearing the end of its life but I can't tell for sure.

Thanks for your reply, i will think about it. Maybe just 1 shot hentam 86u

Btw, if i use AX router as main router, then move my AC68u upstairs and setup wired aimesh, it can work right? Not too familiar with mesh network, but i suppose with an old AC node, it won't force the AX to downgrade to AC to maintain compatibility right?

I not too familiar with AiMesh either but I would expect the AX86U working on AX mode while the AC68U working on AC mode when connected through cable.

Pull trigger on Dlink Dir-x5460 during 9.9 Sales.

Hopefully not regret for it coz after long consideration dilemma between TP link AX73 and Dlink Dir-x5460

AC68U work well as aimesh node for AX series router via both wired and wireless

Good info. Thanks

Tempted to pull the trigger on an AC68U this 9.9 sale. Single storey with 500Mbps Unifi package.

Does it work like this, so if my wifi 6 client connect to AX router then connection is AX, and when it connects to AC node, then connection drop down to AC?

yes

Hi, hope anyone can give me some suggestion to solve the problems I am having now.

I am subscribed to Unifi 5mbps package. Using the original D Link DIR-825M router provided by TM. I have added 3 units of Deco M9 Plus for wireless mesh setup in my three storeys home. I have placed each floor each with one Deco M9 Plus.

The problem is, the wireless mesh signal is not strong on the first and second floor, due to walls blocking etc. Now I'm looking to sell of my M9 Plus and get me a new seetup that can solve my problems: Weak signal strength due to walls.

I have called a few network product sellers, they are suggesting that first thing to change is the D Link router provided by TM. Then buy 3 x wifi 6 mesh routers for each of the floor. They suggested Netgear Obi or the Deco AX90 from TP Link.

My budget is around RM 3,500+ - . Can anyone help to suggest some models based on my budget please? Sorry I am really noob in networking solution. I have read a tons of articles but still blur...

5mnps? or 50?
Since your budget so high, u can choose Asus mesh wifi, ASUS ZenWiFi AX Mini (XD4) or even higher spec which is ASUS ZenWiFi XD6.

Bro, now is ax generation. Don't go for AC anymore, kind of waste money if you ask me.

Sorry typo. 500mbps

Then go with that one i choose should be good for you already.
Since got 3 floors, then go for each floor put 1 mesh... And ur current router from Unifi, you can throw sungai already.. unless you want to use it for lan cable purpose or watch unifi tv.
